Maryland’s Oyster Sanctuaries Show Promising Signs by Joe Zimmermann

March 12, 2024 by Spy Staff

Share

At first, oyster biologists were concerned. Monitoring efforts at some restoration sanctuary reefs in 2022 weren’t pulling up many oysters, even though the sites had previously been performing well.

So divers with the Oyster Recovery Partnership went into the water to investigate. What they found there wasn’t a shortage of oysters, but such a dense and mature population that the shellfish had cemented into three-dimensional reefs, thick enough that the team’s patent tongs sampling gear weren’t able to get them out of the water.

“We’re excited because we feel like we’re starting to reach our goal of self-sustaining reefs,” said Olivia Caretti, the partnership’s coastal restoration program manager. “In another sense, it becomes a question of how we adjust our sampling plan. It’s a good problem to have.”

These sites in the Tred Avon River are a part of an ongoing and long-term experiment in oyster recovery. In an effort to shore up declining numbers of the bivalve, Maryland dramatically expanded oyster sanctuaries in 2010 to cover 24% of historic oyster habitat in the Bay, a span of about 9,000 acres spread over a wide geographical area.

Then, in June 2014, Maryland and other regional governments signed onto the Chesapeake Bay Program’s Chesapeake Bay Watershed Agreement that outlined a goal to “restore habitat and populations in 10 tributaries by 2025 and ensure their protection.”

Maryland and Virginia split these 10 tributaries, and both states embarked on five large-scale restoration projects. In Maryland, these are known as the “Big Five” sanctuaries in Harris Creek and the Little Choptank, Tred Avon, St. Marys, and Manokin rivers.

Now, nearing 10 years after the agreement, Maryland’s restoration sanctuaries are on track to be completed in time to meet next year’s goal. Across these restoration sanctuaries, scientists are finding impressive signs of recovery, with considerable reproduction and the establishment of dense, vertical oyster reef structure.

“The success of these restoration sanctuaries is a testament to years of dedicated work,” said Maryland Department of Natural Resources Secretary Josh Kurtz. “DNR and our partners are taking oyster restoration seriously, and it’s great to see our efforts result in these productive, living reefs.”

The restoration work is carried out by the Chesapeake Bay Program’s Maryland Oyster Restoration Interagency Workgroup, a partnership between the National Oceanic and Atmospheric Administration, the U.S. Army Corps of Engineers Baltimore District, the Oyster Recovery Partnership and the Maryland DNR.

Of Maryland’s Big Five restoration sanctuaries, initial restoration is complete at four, and Harris Creek is considered fully restored. In 2022, Harris Creek had an average density of 462 oysters, including spat and small oysters, per square meter.

At the fifth large-scale restoration sanctuary, Manokin River, initial restoration work began in 2021 and DNR estimates it will continue until 2025.

Evaluating the Oyster Restoration Sanctuaries

The restoration sites are exceeding success metrics established by the Maryland Oyster Restoration Interagency Workgroup. The workgroup’s  2021 Oyster Monitoring Report on these large-scale restoration sites showed that 100% of 3-year-old and 6-year-old reefs that year met the minimum success criteria for oyster density–15 oysters per square meter over 30% of the reef area. More than 90% of the reefs had more than 50 oysters per square meter in the same area.

The 2022 and 2023 reports are scheduled to be released this spring, but DNR scientists think it’s likely that the trends already seen will continue.

“The five large scale sanctuaries have significant populations of oysters, given the massive plantings and the occurrence of natural spatset,” DNR Shellfish Division Director Christopher Judy said. “The next monitoring report will likely show a continuation of past results.”

DNR’s own oyster monitoring across the Bay has found that restored sanctuaries are high in oyster density, reproduction, and cultch (the shell or substrate necessary for juvenile oysters to grow on) as well as low in mortality.

From 2012 to 2022, DNR spent $49 million to restore oysters in the five large-scale sanctuaries. By the end of 2022, partners had planted 5.93 billion juvenile oysters and created 894 acres of oyster reefs at the Big Five sanctuaries, according to the working group’s 2022 Chesapeake Bay Oyster Restoration Update. Previously, these sites had only 42 acres of existing reefs that met the restoration metrics, which did not require initial restoration.

The Need for Oyster Restoration

Scientists and environmental advocates say this considerable undertaking was necessary to begin to address the need for oyster recovery.

Once far more abundant in the Bay, eastern oysters plummeted to a fraction of their early-1800s population due to historic overharvesting, disease-related mortality, habitat degradation, and reduced water quality.

The bivalve is a keystone species, a critical part of the ecosystem of the Bay, as well as an economic driver for the region, making restoration a priority. Oysters also serve as natural filters in waterways. Scientists estimate that adult oysters can filter more than 10 gallons per day in the Chesapeake Bay.

Sanctuaries are permanently closed to harvest, except on aquaculture lease sites, and intended as areas where oysters can grow undisturbed. This enhances the oyster broodstock population and allows the bivalves to build reefs that offer crucial habitat to many other Bay species.

Scientists hope that sanctuaries could also help facilitate pockets of natural disease resistance. In theory, oysters that survive after an outbreak of an oyster disease could better pass on their resistance if left undisturbed in a sanctuary setting. The diseases MSX and Dermo lead to significant die-off in Chesapeake Bay oysters in previous decades.

Restoring a sanctuary involves building cultch, the hard substrate that can support reefs, and planting spat, or juvenile oysters. The University of Maryland Center for Environmental Science’s Horn Point Laboratory in Cambridge grows most of the oysters that supply these restoration efforts.

This fall, DNR’s annual dredge survey on juvenile oysters found prolific spatfall across a wide distribution of the Bay, both in numerous harvest areas and sanctuary areas. (Spatset or spatfall refers to oyster reproduction in an area.) It was the fourth consecutive year of above-median results for juvenile oysters. Data from the survey also indicates that sanctuaries are performing about on par with previous levels and expectations.

Environmental conditions in the Bay, such as higher salinity, have been more favorable to oysters in recent years, likely playing a major part in the increased spatfall. But research suggests that restored sanctuaries provide areas where oysters can thrive in the long term, especially when these environmental conditions are right.

Visualizing Oyster Restoration

Using underwater photographs from tributaries of the Chesapeake in Maryland and Virginia, scientists at the Smithsonian Environmental Research Center analyzed oyster habitats at 600 sites, including areas that were restored and unrestored, as well as sanctuaries and harvest locations.

Comparing the percent of the bottom covered by oysters and the amount of verticality—which indicates the buildup of reef structure—at these sites, restored sanctuaries performed notably well.

“Generally the reefs that are in the best condition at a Chesapeake-wide scale are the ones that are both protected from harvest and have seen restoration,” said Matt Ogburn, a senior scientist at the Smithsonian Environmental Research Center and an author of the study, which was published in October in Marine Ecology Progress Series.

Oysters form reefs on older shells or other hard surfaces, and these structures grow vertically over time. These oyster reefs form the foundation of an underwater ecosystem, providing habitat for fish, crabs, shellfish, and other marine life. The reefs act as nurseries for small fish and hunting grounds for larger fish, which makes for prime angling for sport fish like striped bass and black drum.

Vertical reefs also provide more space for oyster spat to grow, which in turn leads to increased density. Vertical reefs allow the mollusks to stick up higher in the water and have greater access to algae, increasing water filtration, Ogburn said.

Sites that are harvested rarely have this vertical structure, Ogburn said. Harvest sites might be covered in oysters, but they’re all laying down flat at the bottom.

“A core finding of our study was that when oysters are protected from harvest like in the sanctuaries, those oyster reefs all look really good,” Ogburn said. “They often meet the restoration metrics or exceed them, and they also support other species.”

Can Restoration Sanctuaries Reseed Oyster Harvest Areas?

While sanctuaries have seen positive growth, it’s not yet clear how sanctuaries are affecting the overall oyster population in the Bay. Most sanctuaries are relatively new, and DNR scientists suggest that it will take time to gather all the data and have a better understanding of the Bay-wide benefits of sanctuaries.

The next five-year report will come out in 2026, and DNR scientists will analyze that data to determine if there are any indications that restored sanctuaries are contributing to spatset outside sanctuary boundaries. The DNR Shellfish Division has also been planting half-acre shell sites outside the Big Five sanctuaries since 2018, which could help demonstrate whether spat is spreading, either from sanctuaries or harvest areas.

When oysters reproduce, they release eggs and sperm into the water column. Fertilized eggs then develop into free-swimming larvae that drift in the water for two to three weeks before latching onto a hard surface—often other oyster shells. There, the larvae develop into mature oysters and remain sessile, locked in the same spot, for the rest of their lives.

A model developed by researchers at the University of Maryland Center for Environmental Science suggests that larval oysters are able to spread widely before settling down.

Oyster larvae are extremely small—tinier than a grain of sand—and scientists can’t follow them in the water, said Elizabeth North, a professor at the University of Maryland Center for Environmental Science who studies the influence of water flow on oyster larvae in the Chesapeake Bay. But the movement of the larvae can be estimated.

The percent of simulated larvae released from Harris Creek estimated to settle into other regions or back to the sanctuary (blue percentage). Via Elizabeth North, University of Maryland Center for Environmental Science

With a simulation that took into account tides, river flow, salinity, temperature and a number of other factors, North’s team predicted that greater than 95% of larvae end up leaving their reef of origin and settle somewhere else.

Oysters benefit from having a network of reefs that act as “landing strips” to catch larvae as they drift, North said. Some reefs are naturally suited, because of their size or position in the water, to be the “population hubs” that send larvae to other reefs, while others collect larvae but don’t contribute as many to other reefs. Restoration efforts have created new “landing strips” for oyster larvae.

North said oyster larvae are certainly leaving from restoration sanctuaries, though it’s not yet clear how much the larvae then populate the oyster bars of the commercial fishery, or how many of the larvae from commercial areas populate the sanctuaries that have “landing strips” in them.

“There’s no doubt in my mind that any reefs that have oysters on them, especially high density, 50 per square meter and higher, are broadcasting larvae to other areas,” she said.

Restoration and the Long-Term Outlook for Oysters

Though the Chesapeake Bay oyster population continues to face challenges, there have been other promising signs for oysters, aside from spatset numbers and reef growth. In the past two seasons, Maryland oystermen have brought in the highest number of oysters since 1987, at least in part due to successive years of good spatsets that generated increased numbers of oysters.

The 543,000 bushels in 2021-2022 and 722,000 bushels last winter resulted in a dockside value of $21.5 million and $31 million, according to the DNR Shellfish Division.

The spatset in 2023 marked the fifth highest in 39 years, with a historic geographic distribution that far exceeded prior spatsets, a recent milestone in natural oyster reproduction in the Bay. Shellfish biologists were finding spat in areas where they were rarely observed, including in the upper reaches of some Bay tributaries that are typically too brackish for strong oyster reproduction.

And restoration efforts continue apace. Last year, a record 1.7 billion new juvenile oysters produced at state hatcheries were planted on sanctuary and public oyster fishery sites in Maryland’s Chesapeake Bay.

Aside from restoration sanctuaries, there are some unrestored sanctuaries that are doing well. The Nanticoke River sanctuary, which received some limited small-scale restoration since 2020, had an average density of 417 oysters per square meter in 2022. Hooper Straits sanctuary, which received no restoration, had an average density of 294 oysters per square meter in 2022.

But some other sanctuaries that have not received restoration are performing less well. These sites tend to be in lower salinity areas, which are less favorable to oyster reproduction, or in places that didn’t have a lot of good oyster habitat prior to 2010.

But DNR scientists say these sites also present opportunities to get more oysters in the water and further restoration efforts.

“Right now, we have considerable unrestored sanctuary areas that are unproductive because they lack suitable substrate,” said DNR Fishing and Boating Services Director Lynn Fegley. “These areas will need investment to begin producing oysters, and this could come in the form of restoration sanctuaries or in the form of multi-use areas that include aquaculture and some wild harvest. The overarching goal is more oysters in the water and improved ecological function.”

In February, the Chesapeake Bay Foundation released a report calling for additional oyster restoration in Maryland and Virginia, highlighting the benefits oysters provide economically and environmentally, including their ability to protect shoreline habitats from erosion. The Chesapeake Bay Program will determine and approve any new goals for the Bay.

Smaller-scale restoration projects are in the works. In January, DNR committed to planting 147 million oyster spat in Herring Bay Sanctuary with mitigation funds from the Ever Forward running aground on an oyster bar in March 2022.

Cody Paul, a Dorchester County waterman who’s harvested oysters for 13 years, has worked with the Oyster Recovery Partnership on monitoring in the Choptank and Tred Avon rivers and Harris Creek. He said that, although sanctuaries remove bottom areas from harvest, he sees the benefit of them too, from helping build the overall broodstock of oysters to contributing to water filtration.

“The first time I ever went, it was jaw-dropping what you would see there,” he said of the sanctuaries.

Ben Ford, the Miles-Wye Riverkeeper with the environmental nonprofit ShoreRivers, has monitored and captured footage at oyster sanctuaries on the Eastern Shore and said he’s impressed by the recovery he’s seen.

“Oysters loom so large in our culture and our history and our environment,” he said. “So it’s great to give back and have that persist. I know it sounds trite, but for our kids and their kids—I have an almost 2-year-old and I want him to see what I’m seeing, and maybe something even better.”

The Eagle’s Owl Nest: After Years of Teasing, This Great Horned Owl Couple Finally Delivers

February 28, 2024 by Val Cavalheri

Share

In 2020, the Spy published a story about Blackwater National Wildlife Refuge (NWR) that began like this: This was supposed to be a story about eagles. We were going to cover the installation of a camera above an eagle’s nest at the Blackwater National Wildlife Refuge (NWR) in Cambridge, one that would follow the progress of an eagle couple returning to their nest.

Well, this story is now about owls. Maybe.

————-

Fast forward to 2024, and we can update that story, which is now definitely about owls, particularly a nesting Great Horned Owl (GHO) couple expecting the hatching of their two eggs!

To catch up: The Friends of Blackwater (FBW) put up a streaming cam in 2020 to follow the goings-on of a busy eagle’s nest. Unfortunately, the eagles abandoned it at that point (except for an occasional visit now and then). The owls, too, have come and gone, but the rental remained vacant.

Until this year!

“We have a female owl that has been teasing us every year, coming and sitting on the nest and never laying any eggs,” said Lisa Mayo, webmaster for FBW. “She would mimic all the behaviors of an incubating female sitting on eggs. She would look down under herself as if tending eggs, rock back and forth with her brood patch against the nest, but there was nothing there.”

The behavior was repeated winter after winter, to the point that everyone gave up on any ‘egg action.’

This year, the teasing stopped, and two viable eggs appeared!

“One of our cam watchers alerted us, and Lisa went back and grabbed the video from it. When she gets up at night, you can see the two eggs pretty clearly,” said Bob Quinn, who manages the IT equipment for the cams.

Quinn, who retired as the IT Infrastructure Manager for the Consumer Financial Protection Bureau and is now a volunteer at NWR, describes the technology behind the live cam. “We use a PTZ Cam, (pan/tilt/zoom). I can move it vertically, around 360 degrees, to capture various angles,” Quinn explains.

Unlike ospreys, who take turns sitting on the eggs, the female GHO does all the incubating. “We’ve never seen the male change places with her,” Quinn said.” “We have seen her leave for a few minutes and come back. Maybe because the male hasn’t delivered enough food, and she went out for a snack.”

Given their nocturnal nature, cam viewers don’t often see the type of food the male brings to his mate, but it is probably consistent with their diet of mainly small mammals – mice, voles, muskrats, and snakes. Whatever it is, chances are these owls had no problem in their hunt. According to Quinn, great horned owls are apex predators, meaning they are at the top of the food chain. “They’ll take out an eagle. They’re silent fliers and come in from behind. So they’ll fly in and dig their claws into everything, including a larger bird. They’re extremely efficient hunters.”

The big question now is whether these eggs are viable after years of no production from this site. Mayo says it’s hard to know if this is the same couple that’s been teasing them annually. “We can just assume, based on their behavior, it’s likely the same couple. But we can’t guarantee it because we don’t tag these birds.”

The experts are uncertain about the owl’s behavior, theorizing that she is either a new parent or an older owl reaching the end of her reproductive time. “We’re not sure – there are many gaps in the story because you can’t interview them down at the nest!” Mayo said.

A GHO egg incubates for approximately 30-37 days, and the second egg was first seen on February 2nd. Expectations are that the first hatch will happen around the end of this week – beginning of next week (February 28th).  “We’ll definitely be watching even more closely then,” said Mayo. “Just to be able to keep folks updated.”

Volunteer cam watchers always notify Mayo if they see anything interesting happening at the nest. Quinn also monitors the cams even when at home. “I have two screens on my computer in my bedroom. And I keep it up on one of the screens. So that if something happens, like it goes out of focus, I can go in and refocus it. Or if I see an event, I’ll notify Lisa so she can grab the video.”

Motion detectors are also set up as an alert system. Maintaining live cams for a wildlife refuge has its challenges, especially when relying on solar power and rural internet connectivity. Quinn related instances of lost video feeds, sound issues, and inclement weather causing disruptions. “We’ve had some problems where we’ve lost the sound. And it turned out that a piece of equipment got fried, and we had to go out and replace it,” he said.

Obviously, major issues have required some hands-on triage. “We’ve had to go into the woods and reboot.” However, should anything happen while there are nesting birds, they would not be disturbed until after the fledglings have left.

There are currently five live streaming cameras: Two on the Eagle’s Owl’s Nest, an Osprey Cam, a River Osprey cam, and a Waterfowl Cam in the middle of the field, which spins around showing various views of migratory birds during different times of the year. The costs of the live streams are covered by FBW rather than the federal government or wildlife refuge.

Looking ahead, the chances of the owls returning next year seem slim. GHOs don’t build their own nests but take over other birds’ old nests. “Sometimes they’ll make a nest cut out on a rock formation – anywhere that’s convenient,” said Quinn. Unlike eagles, who invest in maintaining sturdy nests and return to them annually, owls trash their seasonal sites. “It’s common that the nest never gets used again,” Quinn added.

In fact, the borrowed eagle nest that currently houses the GHO pair is deteriorating from lack of maintenance over successive winters. Mayo is cautiously optimistic, hoping that if the chicks hatch successfully this year, the nest will hold up long enough for them to fledge successfully.

“Hopefully not this season, but I envision that the nest will eventually form a hole, or part of it will sink, or it may fall out of the tree,” she said. “It’s hard to know what will happen, but something will happen because these owls are not making any effort to strengthen it. It’s not in their behavior.”

For now, all eyes are on Mama GHO as the baby watch begins. But being part of this wildlife reality comes with a disclaimer:  “Our cameras display raw, unfiltered nature that might include wildlife interactions and weather calamities that we cannot control. We have a no-intervention policy, as we are just observers.“

Still, how can we resist a front-row seat to nature’s real-life reality show?

Mid-Shore Ecosystem: Record Breaking Farm Land Saved by QAC but Future Funding Looks Bleak

February 13, 2024 by Dave Wheelan

Share

For the record, Queen Anne’s County has never preserved more agricultural land in its history than last year. With the combination of Maryland MALPH grants and matching funds, a remarkable $5 million was allocated to purchase conservation easements in 2023.

The County’s success in land preservation in 2023 is attributed to state and local funding programs, strategic planning, and community involvement. However, the foundation of the County’s preservation efforts is the Maryland Agricultural Land Preservation Foundation (MALPF) and its matching fund program.

This program is primarily funded through an agricultural transfer tax levied when farmland is converted to residential use. In Queen Anne’s County, 80% of this tax is retained locally, with the remainder sent to the state to support MALPF.

In 2023, the state of Maryland allocated $95 million to land preservation, with each County receiving an equal share of approximately $1.8 million. Counties contributing their funds towards conservation can receive additional matching funds from the state, amplifying their capacity to secure agricultural easements.

Queen Anne’s County has been particularly innovative in its approach to funding land preservation. In addition to utilizing the agricultural transfer tax, the County has leveraged revenue from a solar fee tax, directing these funds toward land preservation. This approach supports the County’s preservation goals and mitigates some of the impacts of solar farm development on agricultural land.

Despite these successes, Queen Anne’s County, like all of the state’s counties, is facing significant challenges in the future.

Maryland has projected substantial reductions in land preservation funding for 2025 and 2026, with anticipated budget cuts of two-thirds from the 2024 levels. This reduction poses a real threat to the County’s ability to continue its land preservation efforts at the current scale. The County’s proactive measures, such as leveraging solar fee taxes, may provide some cushion against these cuts, but the overall effectiveness of land preservation initiatives is likely to be impacted.

In response to these challenges, county officials and advocates for land preservation are calling for sustained commitment to funding preservation programs. They argue that the investment in land preservation not only supports local agriculture and maintains the County’s rural character but also offers a strong return on investment by stimulating local economic activity and ensuring the continued vitality of the agricultural sector.

The Spy asked Donna Landis-Smith, who has headed up this project for the last 19 years for Queen Anne’s County Soil Conservation department, and QAC’s commissioners Jim Moran and Jack Wilson, two of the program’s leading advocates, to discuss how successful this state-local program has been and the challenges of funding these priorities in the future.

Md. Offshore Wind Project Loses Energy: Developer Announces ‘Repositioning’ Of Project

January 26, 2024 by Maryland Matters

Share

Maryland’s nascent offshore wind energy industry suffered a major blow late Thursday when one of the two companies planning to install wind turbines off the coast of Ocean City announced that it was “repositioning” its plans, pulling out of its agreement with the state and seeking alternative financial arrangements to keep the project going.

Ørsted, the world’s largest developer of offshore wind, emphasized that it was still committed to building its project in federal waters, but said it was opting out of the agreement it had reached with the Maryland Public Service Commission for financial clean energy credits intended to help fund the development. The company said that while it would still seek permits for the proposed wind farm from the federal government, and would continue to develop construction and operations plans for Maryland, the current financial realties of the offshore wind industry made it impossible to continue under the present arrangement.

Through two separate but adjacent leases known as Skipjack 1 and Skipjack 2 that had won state approval, Ørsted is ticketed to provide 966 megawatts of wind energy beginning later this decade. A company executive said Ørsted was determined to work with state officials, potential investors and other stakeholders in an effort to find a better way to finance and save the project.

“Today’s announcement affirms our commitment to developing value creating projects and represents an opportunity to reposition Skipjack Wind, located in a strategically valuable federal lease area and with a state that is highly supportive of offshore wind, for future offtake opportunities,” said David Hardy, group executive vice president and CEO Americas at Ørsted. “As we explore the best path forward for Skipjack Wind, we anticipate several opportunities and will evaluate each as it becomes available. We will continue to advance Skipjack Wind’s development milestones, including its Construction and Operations Plan.”

By saying the Danish company was exploring “future offtake opportunities,” Hardy was signaling that Ørsted will be looking for new funding streams, new investors, new government programs that could potentially generate additional capital, a new rate scheme for electricity consumers — or some combination.

But it isn’t quite clear where the discussions in Maryland will go from here.

The Challenge of Solar Farms on the Shore: A Chat with Eastern Shore Land Conservancy’s Steve Kline

January 10, 2024 by Dave Wheelan

Share

Solar farms, at least in the abstract, seem to be one of the more perfect solutions for this country’s crippling dependence on fossil fuels. Passive and free rays from the sun generate a reliable source of energy while at the same time offering struggling farm landowners the opportunity to repurpose their property so they can leave a financial legacy to their families. Case closed, so to speak.

But Steve Kline, president of the Eastern Shore Land Conservancy, says in a long-form interview with the Spy that the issue is far more complex and challenging when discussing the challenges facing solar farm development on the Mid-Shore of Maryland. And that includes the insight he shares that 60% of farm acreage in this region is leased, not directly farmed by the owners. This leads to a fundamental disconnect in land-use decisions, particularly concerning the adoption of solar farms.

Kline notes that this significant shift in local land-use decision-making is important. Utility-scale solar projects (over two megawatts) bypass traditional municipal or county planning processes, a change driven by court decisions and statutes. This controversial preemption may undermine local authority and public involvement in land management.

Steve also notes that the Eastern Shore Land Conservancy is grappling with integrating solar development while preserving substantial agricultural land. A major concern for ESLC is the long-term impact of solar farms on agricultural land. Contrary to the solar industry’s portrayal of solar farms as temporary land use, Kline argues that the transformation is effectively permanent, jeopardizing the future of agriculture.

Maryland has witnessed a significant reduction in farmland over the past decades, a trend that solar farm development could exacerbate. Kline highlights the economic implications, noting that large-scale solar development could drive full-time farmers out of business, as agriculture also requires extensive contiguous lands for viability.

A particularly alarming aspect Kline mentions is the removal or displacement of topsoil in solar farm setups, which could have long-term detrimental effects on the land’s agricultural potential. To mitigate these impacts, ESLC proposes a mitigation fund. For every acre of farmland converted to solar use, a fee would be imposed to fund conservation efforts in the same county, aiming to balance out the agricultural land loss.

Kline stresses that the rush to deploy solar energy should not overlook the critical nuances of land use and conservation. He underscores the need for public engagement and legislative attention to ensure a balanced approach that respects both renewable energy goals and agricultural preservation. The interview ends with a call for citizens to communicate their concerns to legislators, emphasizing the importance of deliberate, well-informed decision-making in this critical area.

But the reality of using precious farm land for solar harvesting is simply not that simple. And this is particularly true on the Mid-Shore and its unique abundance of potential sites for new solar installations.

A Conservation Journey From Cordova to Palaka and Back to Delmarva by Norman Greenhawk

January 1, 2024 by Spy Daybook

Share

Editor’s Note: As part of the Spy’s welcoming of the new year, we thought our readers would particularly enjoy this inspiring story by Mid-Shore native Norman Greenhawk and his conservation journey from Cordova to the Philippines to create the Harris Conservation Initiative and his plans for the Eastern Shore.

Twenty years ago, if you told me that I’d be writing this from the Philippines, I wouldn’t have believed you. It’s a far cry from Cordova, Maryland, where I was born and raised. Like most people in town, my family is working class; anyone familiar with Easton Farmers’ Market likely knows my mother’s business, CD Produce, a mainstay at the Saturday market for over 20 years. My grandfather spent his life as a construction worker at James Julian Construction in Delaware. My grandmother worked as a cafeteria manager at the Moton and Dobson buildings at Easton Elementary School in Easton, Maryland. My mother supported our family with her market produce business, and even after retirement, my grandparents helped us on the farm and at our family’s produce stand. 

Harry and Stella Harris of Cordova

My grandparents, Harry and Stella Harris, lived just a mile from my house, and so every weekend I’d stay over from Friday afternoon until Sunday evening. We had a tradition; every week, we’d tune into Wild America and National Geographic documentaries that were aired on Maryland Public Television. These nature programs showed me a world that seemed like fantasy, with brightly colored treefrogs peeking out of bromeliads, giant birds swooping to catch prey, and forests that seemed older than time. My grandfather would take me fishing for bluegill and smallmouth bass at the “gravel pits” owned by his employer. My grandmother would buy every book that caught my eye; the topics usually centered on dinosaurs, tropical forests, frogs, lizards, and botany. My grandfather shared with me his passion of raising aquarium fish and tropical birds. When I wanted my first pet frog, he helped convert an old fish tank into a setup appropriate for housing amphibians. 

They supported my love of nature and the outdoors, but more so, they encouraged my education. I’m the first member of my family to graduate from college, earning my undergraduate degree in Environmental Studies from Washington College in 2003. My career took me away from the Eastern Shore of Maryland. I’ve lived 11 years in Puerto Rico and five years in the Philippines. I’ve also worked and trained in Belize, Honduras, and Panama. My passions are conservation, herpetology (the study of reptiles and amphibians), forest ecology, and habitat preservation.

My specialty is ex-situ conservation, specifically, taking endangered animals from the wild, breeding them in captivity, and then returning the captive-bred offspring to the wild to boost populations. In 2015, my Fulbright award took me to the Philippines, where I established Project Palaka, the first organization in the country that focused on “ex-situ” (captive breeding) of endangered Philippine amphibians. We’re currently working to conserve and protect the Gigantes Limestone Frog, Platymantis insulatus, the most threatened frog species in the Philippines. Our team conducts population monitoring and threat assessment, in the remote Gigantes Islands, located in the Visayan Sea in the Philippines. We also have an assurance colony of the frog set up in Subic Bay, Zambales. Since October 2022, Project Palaka has been breeding the Gigantes Limestone frog in captivity, with plans to start reintroduction in late 2024.

Over the past two years, I’ve considered how to bring my experiences home to the Delmarva Peninsula. While my grandparents always worried about me, they supported my travels and work around the world. They have since passed on, and I miss them daily.  As a way of honoring their memory, I created The Harris Conservation Initiative (“HCI”). Formed in 2021, HCI is a 509 (a)(2) charity. Through this organization, I seek to enact real, measurable conservation actions that focus on overlooked, understudied, and ignored species of herpetofauna and freshwater fish. I have established partnerships in the Philippines, Puerto Rico, and Belize. Now, I’m developing projects in two additional areas- Japan, and back home on the Delmarva Peninsula.

The Delmarva Peninsula, although small, contains six ecoregions and five types of wetlands. The Peninsula’s diverse habitats, from the forests of the Piedmont Uplands near Pennsylvania to the coastal wetlands, are home to 70 species of reptiles and amphibians and more than 40 species of freshwater fish. Conservation organizations around the world rightly focus on protecting the biodiversity of developing nations, where threats to the environment are often intensified. But that doesn’t mean that developed nations have solved all of their ecological concerns.

On a local level, I’m aiming to set up a network of study sites to monitor target species across various ecosystems on the Delmarva Peninsula, to establish updated baseline populations of threatened species, as well to enact data-driven conservation measures to protect Delmarva’s herpetofauna. I am also highly open to collaborating with local, established NGOs and conservation groups.

Just as importantly, I also began the Harris Conservation Initiative to provide the same opportunities that I have had to others. A major goal of the organization is to facilitate a research and collaboration exchange program between each project. From my time my graduate program at the Universidad de Puerto Rico, I know that every year, Puerto Rican students travel to Maryland’s Western Shore to engage in ecological research. I’d like to open that opportunity to the Eastern Shore and Delmarva, so that students from abroad can experience not only the peninsula’s unique natural landscape, but culture as well. I also want to see talented college students from Delmarva travel to and gain experience in herpetological surveys in Belize, or tropical forestry in Puerto Rico. 

I believe that by providing these opportunities, young, aspiring conservationists will be able to gain experience working in ecosystems that they otherwise might not. 

Norman Greenhawk is the director of the Harris Conservation Initiative. He is a graduate of Washington College and is holds a Master Herpetologist certification from  The Amphibian Foundation. He is also a recipient of the National Geographic Explorer award and a U.S. Department of State Fulbright Specialist. He currently lives in Philippines.

Environmental Reclamation and Sustainability for the Bay: The Poplar Island Project

December 16, 2023 by Matt LaMotte

Share

Dr. Michael Erwin

Recently retired career field biologist and college professor Michael Erwin, Ph.D., penned a scientific memoir, Birds, Beaches, and Biologists (2023, Austin Macauley Publishers, NY), chronicling a lifetime of teaching and field research in such exotic locations as Guyana, Trinidad and Suriname. But the book’s final chapters focus on Erwin’s decade-long dedication to the ongoing Poplar Island reclamation project here on the Chesapeake Bay.

Officially titled the Paul S. Sarbanes Ecosystem Restoration Project at Poplar Island, the reclamation effort has evolved into a model “Beneficial Use Project.” It is now the largest of its kind globally. It also reflects successful cooperation and coordination between Federal, State, and local organizations.

The interagency team includes the U.S. Army Corps of Engineers (USACE), the U.S. Fish & Wildlife Service (USFWS), the U.S. Geological Service (USGS), the Maryland Department of Natural Resources (DNR), and the Maryland Department of Transportation/Maryland Port Administration (MDOT/MPA). The University of Maryland (UMD) and University of Virginia (UVA), where Dr. Erwin ended his over 40-year research career, also played important roles.

The history of Poplar Island goes back to well before colonial times. By the mid-1800s, surveys showed that the island was around 1,200 acres; by 1900, there were nearly 100 residents. Besides several farms, the island had a post office, a church, and a school. Erosion was already taking its toll, and by the 1930s, it had been reduced to about four acres of “drowned wetlands.” By the 1990s, Poplar Island seemed doomed to extinction.

In 1996, the Maryland General Assembly passed a declaration stating that “all material dredged (from Baltimore Harbor) must be placed within a confined area or be beneficially reused.” A Poplar Island Research Group – a consortium of federal, state, local agencies, and non-government organizations — produced an Environmental Impact Statement that recommended using dredge material from the Baltimore Harbor to reconstruct Poplar Island as it was first surveyed in 1847. By 2000, environmental scientists like Dr. Erwin began researching the impact of the added dredge material on wildlife on and around Poplar Island.

What remained of Poplar Island was a little more semi-submerged marshland (aka, drowned wetlands) and mudflats that came and went with the tides. Using sand, rock, and stone, engineers built over 35,000 feet of dikes that created containment cells. At present, there are 20 cells. Water was discharged from these cells and dredged material was pumped in. After settling for several years, the remaining soil was graded to create a habitat that would be conducive to wildlife nesting and migratory resting areas. This is where the observations of Dr. Erwin and other scientists became so vital.

Beginning in the late 1990s, Dr. Erwin began working on Poplar Island by serving on a committee focused on project planning and design. In 2003, Dr. Erwin received funding from the USACE to serve as the USGS scientist to assist with designing upland and wetland wildlife habitats as well as monitoring wildlife populations – particularly rare species of waterbirds. For example, the arrival of the American Oystercatcher at Poplar Island has been a notable recent visitor to the Chesapeake Bay.

In the years since, waterbird species of concern, such as Least Terns, Snowy Egrets, Glossy Ibis, Black-necked Stilts, and Tricolored Herons, have begun nesting at Poplar Island. Ospreys have nested in good numbers along with Herring Gulls. In winter, rare Short-eared Owls have been seen. Since the Poplar Island Project began, researchers have identified over 250 species of birds, including close to 40 nesting species. 

Dr. Erwin’s years of field monitoring observations greatly influenced construction decisions for the island. Ultimately, construction decisions were made in no small measure based on Dr. Erwin’s years of field monitoring. It was here that he met and became associated with St. Michael’s own Jan Reese. During both field monitoring and habitat planning meetings, Dr. Erwin remarked that “Reese’s vast knowledge of the Bay’s natural history” proved extremely helpful to him and other researchers at Poplar Island. 

For Dr. Erwin, the Poplar Island Project was the longest as well as one of the most challenging projects of his career. “I had a reputation as an expert in the design and monitoring of key species using coastal habitats. It was challenging coordinating and working with the variety of engineers, administrators, and research scientists on the numerous upland and wetland decisions that were ultimately made.” In particular, the numbers and variety of colonizing, nesting, and hatching success of coastal waterbirds – many declining species – was an important highlight for Dr. Erwin. 

“As far as the future of Poplar Island, there is an ongoing need for natural resource monitoring and management,” stated Dr. Erwin. “Continuing public tours and education to make sure the island remains a wildlife and fisheries magnet – not to mention a dredged material depository – will be an important component of the ultimate success of the Project.”

Dr. Erwin retired in 2012, including from the Poplar Island Project, but he stays in touch with others he’s worked with and mentored even today. Construction and restoration, as well as monitoring and wildlife management at Poplar Island, is scheduled to continue until 2040. It should be noted that a similar project at James Island is just getting underway based on the Poplar Island model that he was instrumental in establishing.

“In the near future, we need to continue to assess and limit the degree of predation there – especially focusing on nesting birds,” said Erwin. “We should continue limited public tours, scientific research, and education visits to keep everyone aware of the invaluable wildlife and fisheries magnet that Poplar Island has become.” 

Dr. Erwin has dedicated more than 40 years to wildlife research, management, and conservation. As reflected in his memoir Birds, Beaches, and Biologists, Erwin’s career should inspire us to restore and sustain our delicate ecosystem. Poplar Island is a model example of how mankind can turn the tide and, particularly in the Chesapeake region, help reverse the ongoing loss of unique island habitats.

Washington College’s Natural Lands Project Creating More Wildlife Habitat

December 14, 2023 by Dennis Forney

Share

Dan Small, coordinator of Washington College’s Natural Lands Project, uses prescribed burning as one of the tools available to help maintain early successional grasslands on Maryland’s Eastern Shore

“The long-term efforts managing early successional habitat at our model farm, the River and Field Campus, have shown us that when you make a dedicated effort to set aside marginal cropland and install early successional habitat, birds will thrive.” – From Washington College’s Natural Lands Project website

Proof of that opening statement? Over the course of the last couple of years, at least 32 distinct coveys of Bobwhite Quail have been identified on and around Washington College’s River and Field Campus on the Queen Anne’s County side of the upper Chester River.

Summer surveys have recorded as many as 35 males singing their distinctive bobwhite calls. That’s according to Dan Small, coordinator of the college’s Natural Lands Project, under the umbrella of the Environment and Society department. Go big or go home!

Last week I wrote wistfully about a bygone era when evening summer rides through the Eastern Shore countryside would often be accompanied by the distinctive songs of Bobwhite Quail males. That soundtrack, due to lots of factors, eventually faded away.

This week though I write, more optimistically, about the success of the college’s efforts to return those sounds to the Eastern Shore landscape.

Since 2011, Small has been researching grassland birds such as quail. That research evolved into habitat management and conservation which led in part to creation of the Natural Lands Project in 2015.

The Chestertown college’s River and Field Campus of approximately 5,000 acres is known locally as Chino Farms. Dr. Henry Sears gathered several farms to create Chino in the latter half of the 20th century. Now known as the River and Field Campus, the diverse complex is owned jointly by Sears and the college. The total property includes 2,600 acres of farmland, 1,800 acres of forested woodlots, along with other wetlands and meadows.

“Dr. Sears,” said Small, “set aside 200 acres of that land in 1999 for experimental grasslands where he hosted classes and labs.  The specific goal was to create a successful habitat of early successional grasslands attractive to quail.  Now a thriving population occupies that area along with several other species that have been in decline including lots of different birds. On a summer’s day, it’s not unusual to hear 15 male quail calling in that area.”

Partnering with Maryland’s parks, and other state open space programs, as well as conservation-minded private landowners, the Natural Lands Project aims to replicate that success up and down Maryland’s Eastern Shore. “We advise and provide funds to assist landowners in the process,” said Small.

He noted that in cooperation and assistance with the program, public and private owners have converted more than 1,200 acres of mostly marginal farmland into early successional habitat.  Those are habitats that emerge after clearing events such as cultivation, burning or mowing take place.

If those areas were left undisturbed and unmanaged for several decades, they would eventually evolve into forests.  But management such as prescribed burnings hold them in that early successional grassland phase so preferred by quail and other species, including a number of sparrows.

”A lot of people are interested in helping,” said Small. “On eight of the properties we have converted in recent years, quail have shown up. For two years in a row we have seen successful breeding. We would like to create a corridor of habitat spanning several connecting farms. With proper management, we can have quail in the modern agricultural landscape.”

Small said the Natural Lands Project also contributes to efforts to improve water quality in the Chesapeake watershed by creating natural buffers that keep sediments and fertilizer run-off from entering waterways.

Partnering with Queen Anne’s County, the Natural Lands Project has helped convert 200 acres of farmland into grasslands between the Chester and Corsica Rivers. A parking area at the Conquest Preserve near Centreville invites visitors to walk trails winding through meadows and forests along the Chester. The meadows and five different managed wetlands attract birds, reptiles and mammals, and groups of people who like to watch nature in action. Members of the Talbot bird club, for instance, flocked there recently to add LeConte’s sparrows to their lifetime lists.

Conquest Preserve also includes an edible food forest with a variety of trees and shrubs designed to provide wild fruits for critters up and down the food chain.

“Momentum is growing,” said Small. “Farming operations are passing down to a new generation that is more conservation minded.  They realize the benefits of not farming marginal land and saving on the cost of inputs, as well as the importance of providing habitat for birds and animals.”

Study: Lawn Mowers and Leaf Blowers in MD Produce as much Pollution as Long Car Trips

November 18, 2023 by Maryland Matters

Share

It’s leaf blower season, adding new layers of unwelcome noise to the cacophony of daily life.

Leaf blowers — along with gas-powered lawn mowers, string trimmers, chainsaws and other garden equipment, also generate an alarming amount of air pollution. Some machines emit as much pollution in an hour as driving hundreds of miles in a car.

A recently released report by the Maryland PIRG Foundation, called “Lawn Care Goes Electric: Why It’s Time to Switch to a New Generation of Clean, Quiet Electric Lawn Equipment,” attempts to quantify the public health risks and potential damage.

Analyzing U.S. Environmental Protection Agency data, the report found that gas-powered lawn and garden equipment in Maryland emitted an estimated 597 tons of harmful “fine particulate” air pollution in 2020 — an amount equivalent to the pollution emitted by 6.4 million gas-powered cars over the course of a year.

Montgomery County, which is phasing out the use of gas-powered leaf blowers and leaf vacuums, ranked 16th among U.S. counties for “fine particulate” air pollution in 2020, with Prince George’s, Baltimore and Anne Arundel counties all ranking in the top 100 as well.

“It’s absurd that we have been tolerating so much harmful pollution and noise just to cut grass and maintain landscapes,” said Maryland PIRG Foundation Director Emily Scarr.

The pollutants emitted by gas-powered lawn equipment include fine particulates (PM2.5), ozone-forming nitrogen oxides (NOx) and volatile organic compounds (VOCs), and air toxics such as benzene, 1,3-butadiene and formaldehyde. Exposure to these pollutants has been linked to health problems including asthma attacks, reproductive ailments, mental health challenges, cancer and premature deaths. Because they burn fossil fuels, gas lawn mowers and leaf blowers also emit carbon dioxide, the leading contributor to climate change.

The report estimates the emissions of each pollutant and health impacts for the state and on a county-by-county basis. It also calculates the benefit of taking the gas-powered equipment out of circulation, comparing it to the equivalent of taking a certain number of gas-powered cars off the road.

“Air pollution from lawn equipment isn’t some big, distant problem — it’s happening right in our own backyards,” said Tony Dutzik, associate director and senior policy analyst at Frontier Group, a nonprofit think tank that focuses on transportation and environmental policy, who is one of the authors of the new study. “The data in this report shows that emissions from lawn equipment are an important issue in every part of our country.”

The report recommends that local and state governments use electric equipment on public property and provide financial incentives to encourage the widespread adoption of electric lawn equipment by residents. It further suggests that cities and states consider restrictions on the sale and use of the most-polluting fossil fuel-powered equipment.

“The good news is, for those who chose to not use a rake or other manual tool, cleaner, quieter electric-powered lawn equipment is capable, affordable and readily available,” Scarr said.

Those recommendations align with sections of the preliminary Maryland Climate Pathway report, which the Maryland Department of the Environment issued earlier this year, with suggestions for how the state can meet its aggressive climate goals. A final version of the pathway report is due out next month.

Earlier this fall, the Montgomery County Council voted 10-1 to phase out gas-powered leaf blowers and leaf vacuums. Sales of those items will be prohibited in the county beginning on July 1, 2024, and their use will be banned altogether a year later — with exceptions for large-scale agricultural operations.

As he signed the legislation in September, Montgomery County Executive Marc Elrich (D) said the county was “putting the health and safety of all our community members first,” and said the government would design a rebate program to help residents defray the cost of purchasing electric leaf blowers and vacuums.

Del. Linda M. Foley (D-Montgomery) introduced legislation in the 2023 General Assembly session that would have phased out the use of gas-powered leaf blowers and vacuums, similar to the Montgomery County measure. In addition to several environmental groups, supporters of the bill included the National Association of Landscaping Professionals and the Humane Society of the United States. The Maryland State Firefighters Association supported the legislation but sought an exemption for the Department of Natural Resources, Forestry division fire management team, arguing that battery-powered leaf blowers do not operate for as long a period as gas-powered units.

Several individuals testified against the measure, as did The Maryland Arborist Association, Inc., which argued that the bill would cost tree care companies — and their customers — more money.

The House Health and Government Operations Committee took no action on Foley’s legislation. But Foley said Monday she would be back with similar bills in the 2024 session, with some changes.

Foley said she is changing the phase-out period of her prior legislation to make it “a little more generous” and is expanding the list of equipment covered to include all “non-road” fossil-fuel engines.

“It is a small portion of fossil fuel emissions [in the state], but every bit of it matters,” she said.

Foley said she anticipates putting in a separate bill regarding sales of leaf blowers. In all likelihood, she said, consumers would be required to buy electric yard equipment when their older, gas-powered equipment breaks down.

Adkins Mystery Monday: Whose in the Garden?

October 23, 2023 by Adkins Arboretum

Share
Happy Mystery Monday!  Can you guess what is pictured in photo #1?
The answer to last week’s mystery is the flower head of bull thistle, Cirsium vulgare, pictured in photo #2.
Bull thistle belongs to the artichoke sub-family, and was used by early humans as a warm medicinal tea. The roots helped with poor digestion and the treatment of stomach cramps, while the leaves were used to treat neuralgia.
In addition to medicinal uses, thistle seed fluff can serve as tinder, and the inner bark can be used in paper-making.

Goldfinches are particularly attracted to thistle. Not only do they pull the seeds out to eat, goldfinches use the thistle down, the pappus, to line their nest.

Adkins Mystery Monday is sponsored by the Spy and Adkins Arboretum. For more information go here.
