A new reality for plovers on the Jersey Shore

This story was originally published on our new Medium blog platform

This year’s severe storms underscore the power of nature and the vulnerability of our coasts. While nature can destroy, it can also defend. Supported by federal funding for Hurricane Sandy recovery, we’re working with partners to restore and strengthen natural systems that provide not only habitat for wildlife, but also protection against rising seas and storm surge. This is one in a series of stories highlighting results of our ongoing efforts to build a stronger coast.

On October 29, 2012, Hurricane Sandy plowed ashore near Atlantic City, N.J., with sustained winds of 75 miles per hour. In its wake, state officials declared it the most destructive natural disaster in the history of New Jersey. It changed communities dramatically.

There were flooded roads, fallen power lines, and 346,000 damaged homes.

Natural features of the coastline underwent significant changes too, but in some cases, those changes presented new conservation opportunities that could protect people and wildlife in the face of future storms.

“We were able to identify places where piping plover habitat had been enhanced by the storm,” explained Todd Pover, a senior biologist for the Conserve Wildlife Foundation of New Jersey who has been involved in monitoring the federally threatened shorebird for 25 years. Places like Edwin B. Forsythe National Wildlife Refuge, where the storm erased the dunes in a three-quarter mile stretch of beach, creating an open expanse from ocean to bay.

“It’s what we refer to as an overwash fan,” Pover said. “The most desirable habitat for plover.”

It was a good sign for the future of these birds in New Jersey. Although the number of nesting pairs along the Atlantic coast has nearly doubled since piping plover was placed on the Endangered Species List in 1986 — the species has since been downlisted from from endangered to threatened — New Jersey’s breeding population has failed to launch by comparison. There were 94 nesting pairs in the state in 1986. In 2017, there were 105.

More nesting habitat meant the potential for more nesting pairs.

It was also a good sign for the New Jersey shore. Those overwash fans where piping plover like to nest are the product of wind and wave action continually reshaping the coastline, sometimes dramatically as in Sandy. Allowing coastal processes to play out naturally in areas like these helps absorb impacts of future storms.

“In a sense, piping plover represents coastal resilience,” explained Brooke Maslo, assistant professor of ecology at Rutgers University.

But although the creation of habitat gave biologists a reason for hope in the wake of this storm, it also gave them a reason to plan ahead next time. Agencies that typically respond to natural disasters, like the Federal Emergency Management Agency and the National Oceanic and Atmospheric Administration, follow standard operating procedures — a sort of playbook that identifies roles, responsibilities, and actions to make sure all the bases are covered.

Assistant professor of ecology at Rutgers University Brooke Maslo focuses on developing science to support habitat for beach-nesting shorebirds, including piping plover, black skimmer, and American oystercatcher, the bird in her hands in this photo.

“There wasn’t a similar protocol for biological conservation,” Maslo said. If there was a way to quickly assess and communicate benefits for endangered species, they could incorporate that into the response process too.

Now, thanks to collaboration between Rutgers and CWF New Jersey, there is.

With support from U.S. Fish and Wildlife Service Hurricane Sandy resilience funding, the partners have developed a standard assessment protocol for identifying opportunities to protect functional beach habitat after big storms based on what they learned from the last one.

They started by comparing nesting habitat for four beach-nesting species — piping plover, American oystercatcher, black skimmer, and least tern — before and after Sandy.

“Where did habitat persist? Where was it lost? Where was it newly created? We wanted to be able to quantify habitat changes that occurred as a result of the storm, and to quantify the new habitat areas that could be prioritized for conservation,” Maslo said.

The results have already proven useful as a screening tool when working with communities to develop beach management plans — mandatory for towns that receive federal funding to protect piping plover.

“We suggest what could be the most suitable habitat based on the results, and they give us feedback about what they know to be true about that site on the ground,” Pover said.

It also helps natural resource managers plan for constant change. “The beach will change, so creating set-aside areas interspersed throughout the state gives the birds someplace else to go when it does,” Pover said.

It’s like habitat insurance for plover, and it’s clear they will make the most of their safety net. Although most of the new habitat created by Hurricane Sandy was stabilized to pre-storm conditions, resource managers were able to let nature take its course at the site at Forsythe — a wilderness area where no human infrastructure was at stake.

And?

“In the years after Sandy, we went from 12 to 25 pairs at that site,” Pover said. With a secure place to nest, the birds became more productive, with twice as many fledglings as a typical pair in New Jersey.

“Forsythe is a poster child for what could happen if we protect these sites,” he said.

Biologists now know what to look for in potential nesting sites. With the protocol, resource managers, landowners, and town officials can look for these opportunities in their own communities as well.

And because it was developed with input from agencies like NOAA and FEMA that are on the front lines after a natural disaster, the protocol will help factor benefits for wildlife into the existing response process. That will benefit people too. Wildlife tend to good indicators of threats to communities, or as in New Jersey, a sign that they have reason to hope.

(The Real) Plovers of New York

Beaches, bagels, and ’burbs: the three B’s of Long Island. If you haven’t been to the island—like me, prior to this week—you probably associate the area with some of these trademarks. But do you know about one of the tiniest but most important ‘B’s on the island—birds?

Long Island is a crucial habitat for many birds, including a number of terns, skimmers, and even a few bald eagles. Only if you look very closely in the right places will you see one of the most important birds on Long Island: the piping plover, a tiny shorebird unique to North America that has been considered threatened since 1986.

Atlantic Coast Piping Plovers

Piping plovers are small migratory shorebirds with white and sandy coloring that nearly camouflages them in their beach surroundings. The Atlantic Coast breeding population was listed as a federally threatened species in 1986 and are considered endangered within the state of New York. Their entire Atlantic Coast New York population is concentrated on Long Island beaches, where they make their nests for the spring and summer and fortify themselves for their long journey south. As you’re reading this, hundreds of plovers are preparing for their imminent migration to their wintering grounds in far-off tropical destinations like the Bahamas and Cuba.

Piping plovers love sandy open spaces for their summer homes and thrive on the tiny invertebrates that colonize decaying vegetation known as wrack. But due to major habitat loss and disturbance from beach recreation, plover populations have grown precarious.

Long Island is a crucial site for plover protection and recovery.

Arverne, for instance, is a community on the very western part of the island where there was once no hope for plover reproduction. Now, this site is on track to support the Service’s recovery goal of 575 breeding pairs for the New York-New Jersey area. This success comes after years of dedicated efforts by community members, legislators, and scientists to protect the birds and their environment.

Piping Plovers of the Great Lakes

 And while Long Island habitats like these have become hotspots for the plovers, the Long Island gang is not alone in the state of New York.

There is a Great Lakes piping plover population (say that 5 times fast) that is listed as endangered under the Endangered Species Act. The majority of Great Lakes birds nest in Michigan, but scattered pairs occur in other Great Lakes states including New York. This population went from a low of 12 pairs in 1990 to a high of 75 pairs in 2015, but it remains small enough to be vulnerable to shoreline development, public recreation, predators, human disturbance and extreme weather events.

In 2015, after a 30-year hiatus, Great Lakes piping plovers returned to nest in New York State on the eastern shore of Lake Ontario.

This year there was another documented successful breeding pair that took up residence at Sandy Island Beach State Park in Pulaski, New York. Four plover chicks were reared and fledged while being closely monitored by conservation scientists. The New York State Office of Parks Recreation and Historic Preservation (Parks) designated a protected bird nesting area which allowed these plovers to have a safe place to nest and forage for food. Parks hired full time staff to educate beach goers as well as protect the plovers out on Sandy Island Beach.

Ways to Protect Plovers

 Ways we can help protect all populations of piping plovers is to continue to protect and conserve habitat. If carefully and thoughtfully planned, development can occur on shorelines without affecting nesting plovers or landowner enjoyment or access to the shoreline.

Keeping our distance from the chicks by walking in the water during a health survey, USFWS.

Invasive plants such as spotted knapweed, lime grass and phragmites rapidly take over and alter habitat along the shorelines and dunes, making it less desirable for nesting plovers. Removal of invasive plants each season will help maintain plover habitat.

As a beach goer there are some simple ways we can share the beach with piping plover adults and chicks and help them survive:

  • Follow the guidance on signs and respect all areas fenced or posted for protection of wildlife.
  • Watch these entertaining birds from a distance.
  • If pets are permitted on beaches, keep them leashed and away from birds.
  • Remove trash and food scraps, which attract animals that might eat piping plovers and their eggs.
  • Do not feed animals on or near the beach. Keep your cats indoors.
  • Volunteer as a piping plover monitor, ambassador, or educator on your local beach. Tell your friends and family how to help.

Starting in April, sites with proper nesting habitat are surveyed to locate nesting piping plovers. Once a nest is found it is protected by placing a wire enclosure over the nest. This provides protection from predators, while allowing the adult plovers to come and go for feeding. The entire nesting site is posted to inform people to keep their distance.

You can take initiative to help keep piping plovers safe and continue to allow this amazing migratory species to not only survive, but thrive.

Snail Blazers! Creating a future for one of New York State’s tiniest residents

Imagine yourself in the mist zone of a waterfall.

You are surrounded by dense moss and vegetation and cascading dripping wet rocks.

Chittenango Falls, USFWS

In Chittenango Falls State Park in upstate New York lives several hundred tiny, rare animals that evolved over 2 million years ago.

The Chittenango ovate amber snails are unique to the Empire State meaning you won’t find them anywhere else in the world!

This population is the only known living wild population of these snails at the edge of this waterfall in Chittenango Falls State Park.

The snail, affectionately referred to as “the Chit” or COAS is named for its home. They have a beautiful ovate, egg-shaped shell with amber coloring. The snails thrive in the mist zone of the waterfall, and feed on leaves of plants growing on nearby rocks and vegetation.

For years, biologists feared that a single, catastrophic event such as a toxic spill, could wipe out the entire population of COAS.

This potential devastating truth almost happened after a huge rockslide into their habitat in 2006. This event prompted action and a collaborative partnership emerged between the U.S. Fish and Wildlife Service, SUNY-ESF, the New York State Office of Parks Recreation and Historic Preservation, the New York State Department of Environmental Conservation, and the Rosamond Gifford Zoo to breed and rear the COAS in captivity with intent to release individuals in to the wild.

In the summer season biologists and dedicated volunteers make regular trips to the falls site to complete a species survey and evaluate the health of the COAS population.

On the first of survey of the 2018 season a miraculous event occurred.

Not only were 42 captive reared COAS released in to the wild, but a COAS that was bred in captivity and released last year was found.

This finding is monumental!

This means that individual not only was able to find food and support itself, but was able to overwinter successfully. This is so important as it reinforces the captive rearing techniques being refined at SUNY-ESF and the Rosamond Gifford Zoo.

Some people ask, “Why put all this effort in to protecting a snail?” “What would happen if we just let it go extinct?”

The answer to those questions is we don’t really know, but all species have a role.

In addition, as a federally listed species, the public has entrusted the Service with responsibilities towards recovering the COAS.

The COAS has many champions forging ahead to conserve and protect them. It all stems from a cooperative effort to looking to prevent extinction and maintain a successful wild population one snail at a time.
