Oyster Reef Build on South Reeds Beach a Huge Success

Over 130 volunteers and veterans worked alongside Conserve Wildlife Foundation of New Jerseyand American Littoral Society to establish a near-shore whelk shell bar at South Reeds Beach in Cape May Court House on the Delaware Bayshore on Saturday, April 4, 2015. The shell bar was built to prevent sand loss from wind-driven waves. During the “Shell-a-Bration,” an approximately 200-foot oyster reef was constructed offshore to test whether the reef bars help reduce beach erosion and create calmer water for spawning horseshoe crabs.
“We are rebuilding the habitats of Delaware Bay to strengthen its ecology, its communities and its economy. This reef approach will be a key technique which we will try to expand around the Bayshore,” stated Tim Dillingham, American Littoral Society Executive Director.
The South Reeds Beach Oyster Reef is one of the many projects that American Littoral Society and Conserve Wildlife Foundation are working on to restore the ecology and economy of the Delaware Bayshore, thanks to generous funding by the National Fish and Wildlife Foundation.
“The project focuses on creating resiliency in Delaware Bay beaches while improving their usefulness to horseshoe crabs. We have a great challenge: how do we create a reef to protect against damaging Bay storms without stopping horseshoe crabs from getting ashore to breed,” said Dr. Larry Niles, a biologist who leads the beach restoration efforts for Conserve Wildlife Foundation of New Jersey and American Littoral Society, and has studied Red Knots for three decades. “This project is an experiment to help us do both,” he added.
Shorebirds, like the federally listed Red Knot, depend on an uninterrupted supply of horseshoe crab eggs when they stopover in Delaware Bay during their migration. In recent years, countless horseshoe crab eggs have been lost because of the devastating storms that swept away the beaches they depend on.
“The time-honored migration of Red Knots to reach the eggs of these ancient horseshoe crabs is a wildlife spectacle of global significance right here in Delaware Bay,” explained David Wheeler, Conserve Wildlife Foundation of New Jersey Executive Director. “Red Knots come to New Jersey’s Delaware Bay from as far away as the southernmost tip of South America to feed on horseshoe crab eggs. It is vital that we promote coastal resiliency projects like this one to support the largest population of horseshoe crabs in the world, and the human communities of the Delaware Bayshore alike.”
The new oyster reef will attenuate waves but still allow for horseshoe crab breeding. In existing areas where crabs can breed without interruption, like creek mouths protected by sand shoals or rock jetties, egg densities can exceed ten times the egg densities on unprotected beaches.
The projects are being funded by National Fish and Wildlife Foundation (NFWF) through their Hurricane Sandy Coastal Resiliency Grants Program, and are being developed in partnership with U.S. Fish and Wildlife Service and New Jersey Division of Fish and Wildlife.
“The Delaware Bayshore is a perfect location to demonstrate how communities benefit from their connection to a healthy natural resource base – for fishing, boating, wildlife watching and tourism,” said David O’Neill, National Fish and Wildlife Foundation Vice President of Conservation Programs. “The economies of Bayshore towns have historically been intertwined with the bay. And with the NFWF Hurricane Sandy grant, American Littoral Society and Conserve Wildlife Foundation of New Jersey are already restoring shorelines to make Bayshore natural resources and communities more resilient for the future.”
Event guests enjoyed a barbecue and oysters, and family-friendly activities like a “Green Eggs in the Sand” Easter Egg Hunt. In addition, local leaders and biologists spoke to the attendees about the oyster reef project at a mid-day “Whelk-come.”
Beach nesting birds and New Jerseyans who live along the coast both depend on a resilient shoreline — and plenty of sand.
This season, thanks to a grant from the National Fish and Wildlife Foundation (through their Hurricane Sandy Coastal Resiliency Grants Program), a team led by New Jersey Audubon worked with Conserve Wildlife Foundation of New Jersey, The Wetlands Institute, New Jersey Division of Environmental Protection, and the US Fish and Wildlife Service to make the beach community of Stone Harbor Point more resilient for birds and people alike.
Conserve Wildlife Foundation of New Jersey collaborated with New Jersey Audubon to improve beach habitat for Piping Plovers (endangered in New Jersey), American Oystercatchers and the colonially nesting Least Terns and Black Skimmers. Sand from the southernmost tip of the point was moved to create three areas of higher elevation. The new landscape is expected to benefit Red Knots, Semipalmated Sandpipers, Sanderlings, Semipalmated Plovers, Black-bellied Plovers and others.
Stone Harbor, a small beach town along the New Jersey shoreline will see added coastal resiliency benefits and flood protection due to this innovative project that combined the needs for shorebirds with the needs for shore residents. The Stone Harbor project also included the construction of a wide berm of sand near the beachfront parking lot at the far south end of the town. This aspect of the projects aims to increase flood protection for the residents on the developed area of the island.
The National Fish and Wildlife Foundation (NFWF) is a non-profit organization created by Congress to preserve and restore our nation’s native wildlife species and habitats. NFWF is one of the largest funders of wildlife conservation in the world. They fund science-based projects and community-driven solutions.

CWF Releases its First Annual Report Ever Using a Story Map Format: “2014 Annual Report“
By David Wheeler, Executive Director
Technology has proven to be vital to Conserve Wildlife Foundation’s work protecting rare wildlife species over the years. Our biologists depend greatly on modern technologies to band, track, and share online the journeys of wildlife. Our webcams broadcast the most intimate behaviors of nesting birds and bats across the web. And we seek out ever-evolving communications technologies to spread the word about the inspiring stories of wildlife, from social media and infographs to e-books and Story Maps. These technologies offer newfound abilities to share complex data on multiple levels, while still incorporating the awe-inspiring photography and videos that bring wildlife’s stories to life.
Conserve Wildlife Foundation of New Jersey is excited to offer our 2014 Annual Report in a unique format that utilizes one of those technologies – Story Maps. In the past year, we have explored the wonders of American oystercatchers with our first Story Map – and now the annual report allows all of our projects to be highlighted in this interactive format.

And take an online journey across the state to learn how our projects made a difference in all corners of New Jersey in 2014 – a great year for wildlife in the Garden State!
Each spring New Jersey hosts the largest concentration of shorebirds in North America! From about the first week in May to the second week in June, the biggest gathering of horseshoe crabs in the world comes to Delaware Bay to spawn.
At the same time, hundreds of thousands of shorebirds arrive on the Bayshore to refuel on horseshoe crab eggs at a critical stopover during their migration. Delaware Bay is an extremely important area for a number of at-risk wildlife, including Red Knots and Horseshoe Crabs.
CWFNJ AND MONMOUTH UNIVERSITY PARTNER IN THE BAHAMAS

We totally shifted gears for the second half of our week here on Eleuthera, The Bahamas. Piping Plover surveys took a back seat as we focused on working with 20 students from Monmouth University (MU), who were taking part of in a two-week Tropical Island Ecology course during their winter break.
We settled into the Cape Eleuthera Institute, who hosted the students at their world class facilities for an intense (but fun) regimen of hands-on science research, typically marine based, but a Piping Plover unit was added for the MU students. It was particularly exciting to work with the MU students here in the Bahamas because back in New Jersey we have partnered with MU for over ten years on a beach nesting bird internship program during the summer months.
First up was an evening primer for the students on Piping Plovers, including a brief summary of our efforts in NJ on the breeding grounds and recent work by CWFNJ and others on the wintering grounds in the Bahamas. The next morning we were up early to kick off our trial research project; benthic macro-invertebrate sampling at Piping Plover wintering sites in the Bahamas to try to develop an inventory of their potential prey items, and eventually determine what constitutes a highly suitable foraging site. This was spurred, in part, by field observations of tidal flats that appear to be highly suitable, but have no piping plovers present, whereas similar adjacent flats are covered with shorebirds. Perhaps not all flats are created equal and prey availability is the key.
Students collecting and processing the sediment samples as part of the research to assess foraging quality.
For our field work with the students we chose two sites in Eleuthera where Piping Plovers have been observed; Savannah Sound, a classic low-tide flat in a sheltered area, and Winding Bay, an oceanfront, high-energy beach. The students extracted core sediment samples (20 cm deep) at each site along prescribed transects (10 samples per transect) for two consecutive days. Then it was back to the lab to sift the sand, sort the samples, and identify any invertebrates found. As part of the analysis, the students compared the species abundance and diversity between the two different sites, as well as between different transects within a site.
The results are yet to come and this was just a preliminary test of the methods and logistics involved. We were learning along with the students and while we were happy with the overall outcome, many questions were raised that will have to be addressed if we decide to develop a larger more robust study moving forward. In the meantime, the students got to learn a bit about Piping Plovers in the context of a research project, and inaugurate what we hope is another long-term partnership in the Bahamas.

A special thanks to the staff at Cape Eleuthera Institute for their hospitality and for letting us be part of their innovative learning experience. Thanks to John Tiedemann and Pedram Daneshgar at Monmouth University for setting the wheels in motion and now helping us implement this partnership. And finally, “shout-out” to Taylor Rodenberg for stepping up to assist us with the field work – Taylor was one of our MU interns in New Jersey last summer and happened to be one of the students visiting the Bahamas this winter, so she is part of a small group of lucky people to see (and work with) Piping Plovers on both their breeding and wintering grounds!
CWF RESEARCHERS EXPAND SURVEYS TO ANOTHER ISLAND IN THE BAHAMAS
By Todd Pover, Beach Nesting Bird Project Manager and Stephanie Egger, Wildlife Biologist
Todd Pover, CWF Biologist, surveying for Piping Plovers using the final minutes of daylight.
Our experience so far this week in Eleuthera is a reminder why we do so much pre-trip “recon” for our Bahamas Piping Plover Project. Prior to the trip, we poured over Google Earth maps to try to identify the most suitable habitat for plovers. We read (and reread) the report from the 2011 International Piping Plover Census, the last time any significant surveys were conducted here. Finally, we “huddled” with our partners from Monmouth University so they could help us with logistics, as they have a history of marine-based research here.
Without this preparation we would have been ill prepared, of course, but we still faced many challenges right out of the gate. First and foremost, Eleuthera is more than 100 miles long, with two coasts, so covering even a small portion of the island is difficult in a short period of time. Once we decided which sites were the top priority, we quickly found out that reaching those locations is difficult. There are few official signs to the shoreline on the Atlantic side along the one main “highway”, and many of the “roads” are difficult to traverse, even with a 4WD. A number of turnoffs ended as dead ends or too overgrown to continue.
Piping Plover “Gry E4” was banded as a chick at White Point Beach, southern Nova Scotia in June 2014. Resighted on Spanish Wells and the first time reported after the breeding season.
It also quickly became apparent that Eleuthera’s rocky coast, especially along the western side is not nearly as suitable for piping plovers as we had experienced on earlier trips to Abaco and Grand Bahama. And some of the beaches on the Atlantic side were too narrow to likely support piping plovers. Not surprisingly, the initial day of surveys ended with a lot of lessons learned, but NO piping plovers.
Day Two we took an entirely different tack. We left our vehicle on the mainland and headed out on small ferries to two islands off the northern coast of Eleuthera; Spanish Wells, a residential community with a commercial lobster port and Harbor Island, a resort town known for its famous Pink Sands Beach. Our luck turned around, as we observed 20 piping plovers (with relative ease) including four that were marked with engraved flags that denoted they were Canadian breeders. This was one of the highlights of all our Bahamas trips to date.
We were also able to track the movement of 18 plovers from a high tide roost on the ocean side beach to a low tide flat on the other side of the island as the sun set. From what we learned on Abaco on previous trips to the Bahamas, this type of information is some of the most critical we can collect to help inform future surveys. We definitely earned our celebratory Kaliks that evening!
On the road to nowhere – locating piping plover sites on Eleuthera was a logistic challenge at times.
Our goals for the surveys this week are modest. We are trying to confirm some of the site information our colleagues Pat and Doris Leary gathered during the 2011 International Census, as well as add some additional sites to the survey inventory. We also are trying to visit high value sites, such as Savannah Sound, to determine which tide or portion of the tide is most productive for the surveys. With this information in hand, we hope to do our small part to help make the 2016 International Census next winter the most productive and accurate to date.

“Moonbird is the most famous, charismatic member of a group of mid-sized shorebirds called Rufa red knots, whose numbers have plummeted so dramatically in the past several decades that they just became the first bird ever listed under the Endangered Species Act with climate change cited as a “primary threat.”
Rufa red knots are among the avian world’s most extreme long range flyers (especially in light of their relatively small size). They travel vast distances — some flying over 18,000 miles — in the course of an annual migration that begins in Tierra del Fuego, Argentina, and extends all the way up to the Canadian Arctic (and back again).
Which brings us to Moonbird’s distinction: Because he is so old — he is at least 21 — he is believed to have flown as many as 400,000 miles in his lifetime. The distance to the moon varies, depending on where it is in its orbit, but the average distance is about 237,000 miles. Thus, Moonbird has not only flown the distance it takes to reach the moon — he has also covered the bulk of the return voyage.
Assuming that Moonbird is still living — the last sighting was in May — there are reasons to wonder whether there will ever be another bird that is his equal. Why? Simply put, his subspecies has been devastated, and climate change will only make matters worse — making extreme survival of the sort that Moonbird has achieved that much more difficult.”
Washington Post Science and Environment Reporter Chris Mooney explores Moonbird’s journey, threats to the species, and the recent Endangered Species Act listing of the Rufa Red Knot:
Wildlife conservation organizations leading the efforts to restore New Jersey’s Delaware Bay beaches for at-risk shorebirds today applauded the U.S. Fish and Wildlife Service decision to designate the Red Knot, a migratory shorebird, as “threatened” under the Endangered Species Act. A “threatened” designation means a species is at risk of becoming endangered throughout all or a significant portion of its range.
“This federal designation will make a big difference in strengthening the protections of this incredible shorebird,” said David Wheeler, Executive Director for Conserve Wildlife Foundation of New Jersey.
“Here in New Jersey, we are restoring the vital beach habitat that had been decimated by Hurricane Sandy, and this designation ensures the safeguards we are providing can be complemented along the East Coast,” Wheeler added.
Since the 1980’s, the Knot’s population has fallen by about 75 percent in some key areas. Wildlife biologists believe the major threat to the Red Knot is the dramatic decline of horseshoe crab eggs, an essential food source at the most critical stop over during their 8,000 mile trip from southern wintering grounds to Arctic breeding territory. High-energy horseshoe crab eggs provide nourishment for Red Knots to refuel and continue their journey.
“This is an important and needed step in the conservation and recovery of the Red Knot. It is an essential step in preventing the extinction of this amazing long distance traveler,” stated Tim Dillingham, Executive Director forAmerican Littoral Society.
The largest concentration of Red Knots is found in May in the Delaware Bayshore of New Jersey and Delaware, where the shorebirds stop to gorge themselves on the eggs of spawning horseshoe crabs. In just a few days, the birds nearly double their weight to prepare for the final leg of their long journey.
“The major decline of horseshoe crabs in Delaware Bay is one of the largest threats to the survival of the shorebird,” explained Dr. Larry Niles, a biologist who leads the beach restoration efforts for Conserve Wildlife Foundation of New Jersey and American Littoral Society, and has studied Red Knots for three decades. “Agency groups have been working hard for the last two years, and will continue for the next two years going forward to rebuild the habitat damaged by Hurricane Sandy that the horseshoe crabs rely on. This work is integral to the recovery of the Red Knot and the shorebird’s best hope for survival.”
In the wake of Hurricane Sandy, American Littoral Society and Conserve Wildlife Foundation of New Jersey worked with the U.S. Fish and Wildlife Service, the New Jersey Division of Fish and Wildlife and the New Jersey Recovery Fund to remove 8,000 tons of debris and added 45,000 tons of sand to the beaches just before the annual spring arrival of the Red Knot in 2013.
