At Prime Hook National Wildlife Refuge, Mother Knows Best

A new video from the U.S. Fish and Wildlife Service offers an overview of the coastline and salt marsh restoration at Prime Hook National Wildlife Refuge on Delaware Bay. “Building a Stronger Coast: Prime Hook National Wildlife Refuge” is a behind-the-scenes look at how engaged partners and visionary science came together to improve conditions for wildlife and the local community.

After Hurricane Sandy breached the beach at Prime Hook, spilling salt water into an area long managed as a freshwater marsh, refuge staff decided to work with Mother Nature to build a stronger coast.

“We know that we’re going to see more-frequent intense storms,” said Refuge Manager Al Rizzo, “so we didn’t want to put it back into a situation that was vulnerable to the next storm.” Credit: Citizen Racecar

The $38-million project, supported by federal funding for Hurricane Sandy recovery, rebuilt 4,000 acres of marsh and one mile of dune and barrier beach over 18 months. The restoration, one of the largest and most complex of its kind on the Atlantic Coast, enhances habitat for migratory birds and other wildlife. It also makes the coast more resilient to future storms and sea-level rise.

The refuge is an important stopover site for migratory shorebirds, including federally threatened rufa red knots, which rest and refuel there during their long migrations along the Atlantic Coast. Delaware Bay also has the world’s largest population of horseshoe crabs, which spawn in the spring. The birds can eat their fill of the crab eggs, then be on their way north.

For decades, refuge staff managed the marsh as freshwater habitat for ducks and geese by blocking tidal flow from the bay. Hurricane Sandy flooded the marsh with sea water, killing the freshwater plants.

After closely studying state-of-the-art computer models, managers decided restoring the marsh to its natural state was the way to go. It is open once again to the ebb and flow of the tides, which will let salt-marsh plants and wildlife return.

“The project is an investment that is already paying off,” said U.S. Sen. Tom Carper (D-DE), who is featured in the film. “The dunes are holding up, the marsh is rebounding, and wildlife is thriving. I hope other areas of our country — and the world — can learn from this success.” Credit: Citizen Racecar

The restored marsh will buffer the effects of storms and sea-level rise, protecting private property and public infrastructure, such as roads. Acting like a giant sponge, the marsh will absorb water to reduce flooding. It will also offer recreation, such as fishing, hiking, and wildlife watching. A new low, wide dune and barrier beach offer a natural defense against rising water.

Managers will use storm-tide sensors, placed in the marsh, to gauge the project’s success. The sensors measure wave height, speed, force, and extent during storms. The information will help scientists create better models for storm surge and flood forecasting, as well as understand how restored marshes spread out storm-tide and wave energy.

“Federal funding for Hurricane Sandy recovery has provided us with a window of opportunity to protect this fragile marsh, while also helping protect our coastal bay-front communities from flooding,“ said Delaware Sen. Gary Simpson (R-Milford), who is interviewed in the video. Credit: Citizen Racecar

Returning the coastline to a more natural state makes it a healthier place for both wildlife and people to live — proving that sometimes, Mother really does know best.

Four Years After Hurricane Sandy

This week marks the 4th anniversary of Hurricane Sandy, an event that lives on in the minds and hearts of many of us who call the East Coast home.

In the wake of Sandy’s destruction, the U.S. Fish and Wildlife Service received $167 million in federal funding to strengthen natural defenses and protect communities and wildlife along the Atlantic Coast from future storms.

Four years later, here’s a by-the-numbers look at what we’ve done to build a stronger coast as of October 2016:

  • 3,500 tons of hurricane debris removed from refuges;
  • 5 badly eroded beaches restored on Delaware Bay;
  • 7 refuges installed with solar and back-up power;
  • 20 refuges repaired for visitor and staff safety;
  • 6 dams removed to improve river flow and reduce flood risk;
  • 4,000 acres of invasive species treated;
  • 30,000 feet of living shoreline developed;
  • 1000s of native plants planted to restore wetlands, rivers and marshes;
  • 4 breaches fixed, 9,000 feet of shoreline restored, 500,000 plugs of beach grass planted, 1,000 acres of marsh seeded, and 25 miles of channels dredged at Prime Hook National Wildlife Refuge – one of the largest coastal restoration projects on the East Coast.

Some highlights of our 2016 work:

Removal of the 150-foot-long Hughesville Dam on the Musconetcong River in New Jersey to restore fish passage and reduce flooding risks for the local community – a project that caught the eye of Secretary of the Interior Sally Jewell, who toured the site in September.

Removal of the Pond Lily Dam in New Haven, CT, where local community members and politicians mobilized to bring attention to the flood risks of this dam. In April 2016, volunteers planted native vegetation at the dam site to help stabilize the riverbanks and create an urban nature park for the community.

“We spent a lot of time thinking about what management actions we can employ that will increase the resiliency of the salt-marsh community to sea-level rise, to storm impacts and how can we do that in a way that really maximizes the benefit to the wildlife that depend on it,” says Whitbeck.

Science tells us that the future will include more intense hurricanes and storms like Sandy, causing more damage to coastal ecosystems and communities. In fact, a recent study predicts disastrous floods like those seen during Hurricane Sandy may hit New York City 17 times more often in the next century.

With anticipated rising sea levels, more frequent and intense storms, shifting seasons and higher temperatures, we need to continue to work together to better understand and adapt to changing conditions. Strong natural defenses will help all of us better weather future storms.

People Behind a Stronger Coast: Matt Whitbeck and Miles Simmons

Matt Whitbeck and Miles Simmons are on the front lines of dealing with climate change. Where they work along the coastline of the Chesapeake Bay, scientists say sea levels are rising at rates three to four times faster than the global average. The cause is a combination of rising waters due to global climate change and sinking land, also known as subsidence.

As the supervisory wildlife biologist at the Chesapeake Marshlands National Wildlife Refuge Complex, Whitbeck oversees the diverse habitats of Blackwater, Glenn L. Martin, Eastern Neck and Susquehanna National Wildlife Refuges.

While many may see the impacts of climate change as a looming event in the future, Whitbeck disagrees, saying, “It’s very real here.” Sea-level rise has continually shaped the landscape, turning marshes into lakes and forests into marsh grass. At the predicted rate of sea-level rise, nearly all of Blackwater’s marshes could be permanently inundated by 2100.

That could be disastrous for the refuge’s habitats, plant and animal species. Many of the species found here are uniquely adapted to survive in the refuge’s forests, marshes and shallow water habitats. “All the major taxonomic groups have a species or two that has found a way to exist in a saline environment,” says Whitbeck, such as the salt marsh skipper and the Diamondback terrapin.

“In the spirit of maintaining biological diversity, it is important to conserve salt marshes. So strictly from a conservation biology standpoint, a fish and wildlife conservation standpoint – maintaining all the parts is really the first order of business. Ensuring all these species have all the habitat they need to exist is critical,” says Whitbeck.

Yet the community benefits are equally important, especially as the threats of climate change become more evident. Salt marshes provide huge benefits as nurseries for fish, sponges for soaking up flood waters and reducing coastal erosion, and buffers from storm surge and strong waves.

Miles Simmons, a biological technician at the refuge, grew up on the Eastern Shore and has experienced the effects that storms can have on the environment, but also what kinds of effects a healthy marsh can have.

“Marshes – wetlands in particular – are critical in mitigating the effects of large storms,” he says.

When Hurricane Sandy struck the Atlantic coast in 2012, there was a lot of infrastructure that was damaged, but it could’ve been worse – specifically for the communities around Smith Island, located just south of Blackwater.

Having the healthy intact marsh systems of the Glenn L. Martin NWR along the northern part of Smith Island helped to stop shoreline erosion that was taking place on the western and northwestern shorelines. This “really helps maintain that buffer and give the community a small measure of protection,” says Whitbeck.

In June 2016, Whitbeck and team completed construction on a 21,000-foot living shoreline at Martin NWR that will dynamically benefit the surrounding local area and the environment into the future.

Following Hurricane Sandy, efforts to repair and build resiliency around these coastal communities were aided with the help of federal funding from the Hurricane Sandy Disaster Relief Appropriations Act of 2013. Refuges and communities all throughout Maryland received over $13,096,841 to put towards recovery and resiliency.

At Blackwater, as the shoreline elevation begins to shift, biological technicians like Simmons are conducting vegetation surveys to monitor the changing landscape. This is some of the first opportunities that Blackwater has had to examine the ecological changes that result from elevated water levels.

By continuing to work on the Chesapeake Bay coastline, Matt Whitbeck and Miles Simmons are not only ensuring that Blackwater National Wildlife Refuge is #StrongAfterSandy, but continue to make it resilient in the face of climate change.
