Conserve Wildlife Foundation of New Jersey Releases a New Story Map: “Turtle Gardens”
By: Michael Davenport, Wildlife Biologist & GIS Program Manager
The northern diamondback terrapin is an imperiled species of turtle found in brackish coastal waters along the northeast coast of the United States. Within New Jersey, much of the nesting habitat once used by terrapins has been lost to development and rising sea level. What little suitable nesting habitat remains is often inaccessible to terrapins due to bulkheads or other construction and road mortality is a major cause of terrapin mortality as they cross roadways seeking nesting sites.
Turtle gardens provide suitable nesting habitat for diamondback terrapins where little natural suitable habitat remains or is inaccessible. By enhancing the existing habitat at a site within the terrapin’s range to meet their nesting habitat requirements, terrapins can more safely lay their eggs within an area specifically set-aside for them.
CWF recently partnered with the Marine Academy of Technology and Environmental Science (MATES) on a pilot project turtle garden on Long Beach Island in New Jersey. The newly released Turtle Gardens story map details this project.
For those of us who call New Jersey home, we’ve all likely witnessed the impact human activities have on our environment and the species who thrive here. Although habitat loss, illegal poaching and invasive species can be equally devastating to an ecosystem, the presence of plastic pollution around our state is a threat that almost every individual can be found personally culpable.

Although many forms of pollution impact our native species, the summer months at the Jersey Shore often result in a surge of plastic debris that are left behind or improperly disposed of. Plastic pollution impacts millions of wildlife species globally, and the diverse number of species in New Jersey are no exception.
The plastic pollution that accumulates in our waterways and elsewhere around New Jersey poses a serious threat to native species. Single-use plastic products like plastic bags, bottles, bottle caps, wrappers, straws, and even balloons are not only unsustainable, but particularly dangerous for the animals that may become entangled in them or accidentally ingest them.
A few years ago, CWF’s Habitat Program Manager Ben Wurst and his dedicated group of volunteers who monitor the osprey nests along the coast began to hold onto the trash and debris collected in and around the nests. While it may not be the most visually appealing educational resource, it made the growing problem of plastic pollution personal for Ben, in a way that words aren’t always able to convey.
Plastic bags, one of the most common single-use plastic products, were overwhelmingly prevalent in many of the nests. And osprey aren’t the only wildlife species facing this threat. Seals, terrapins, shorebirds, fish, whales, sharks and dolphins can also be impacted by plastic debris.
The presence of plastic in our daily lives is interminable and difficult to eliminate completely, but there are a number of things we can do to minimize the impact our habits may have on our wildlife!
Clean up after yourself:
Whether you’re spending the day at the beach, having a picnic by a lake, or tubing down a river, make sure you take any trash with you before leaving and recycle what you can.
Be mindful of your surroundings:
If you’re out and about and notice that someone left some trash behind, take a moment to throw it away.
Reduce your consumption:
A number of small changes from millions of people can make a big difference. For starters, invest in reusable shopping bags and water bottles. And cut down on the number of miscellaneous throw away plastics you use, including straws and plastic wrappers.
Donate:
Consider donating to CWF to support our conservation projects and ensure our biologists and our volunteers are able to continue surveying and aiding species in need.
DONATION SUPPORTS CONSERVATION OF NJ’S ONLY COASTAL MARSH TURTLE
by Corrine Henn, Communication Coordinator
Great Bay Boulevard in Little Egg Harbor is a favorite haunt for local fisherman, birders and tourists alike. While many locals and visitors celebrate the summer, Conserve Wildlife Foundation of NJ’s Ben Wurst and his team of dedicated volunteers know that summer can mean something else entirely.
An increase in traffic on Great Bay Boulevard during the summer months threatens the survival of one particular species, the northern diamondback terrapin. Hundreds of female terrapins cross roads adjacent to their native habitat, our coastal estuaries, in search of suitable nest sites each year. Unfortunately, Great Bay Boulevard lacks a formal speed limit and mortality rates as a result of vehicle collisions are just one of the dangers the terrapin face.
“From what I’ve seen and experienced from the beginning of this project is that many more people are more aware of terrapins on the road,” said Habitat Program Manager, Ben Wurst. “It is critical to have the support of the local community as they are the ones who frequent the area the most and can really play a huge role in their long term conservation.”

The Great Bay Terrapin Project has done tremendous work to reduce road kill rates. More recently CWF has been collecting data to monitor the local population by taking measurements and notching individual terrapins as part of a mark-recapture effort. Our volunteers conduct road patrols to collect data on terrapins that are encountered on road and also help ensure that they cross safely. Along the most dangerous part of the road, a barrier fence helps to deter terrapins from entering the roadway. Both the fence and several “Terrapin X-ing” signs, have also aided efforts to curb mortality rates each summer.

Ensuring the future survival of the terrapin is, of course, a collaborative effort. We were especially thankful when Glenn Laborda, Dibyarka Chatterjee and Kristen Schmicker of Absolutely Fish presented Conserve Wildlife Foundation of New Jersey with a $5,000 check from the proceeds they raised throughout the Earth Day weekend in April.

According to Jennifer Ruivo of Absolutely Fish, “People come into the store specifically to see her and are generally much more willing to help, donate, or take information when we have a terrapin in store.” The turtle’s presence in the store garners support by bridging the gap needed for many to see that these animals, our neighbors, are in need of our support.
Following the donation from Absolutely Fish, Absolutely Fish representatives – along with Wurst and CWF Executive Director David Wheeler – conducted a survey of Great Bay Boulevard with CWF intern Carly Sibilia who demonstrated the data collection and notching technique of terrapins.
Stay tuned for post-summer update on CWF’s terrapin projects. And in the meantime, be mindful of your surroundings and be terrapin aware!
Have you ever seen a cute little turtle on the roadside or in a river or lake? Lots of people have had the pleasure of seeing turtles in the wild- as they are often easy to see and not too weary of people! This time of year, turtles are beginning to hatch after months of developing inside eggs that were laid in the spring. When turtles are just hatched they are the most vulnerable to predators and even humans! Most hatchling turtles can fit inside the palm of your hand. Often time humans have the misconception that a small turtle is a helpless turtle. Turtles are wild and unless they are trapped or diseased- they do not need our help!

If you find a turtle, please leave it – even if the surroundings seem strange to you, it probably feels right at home. Moving turtles away from their home range can cause disorientation and leave it vulnerable to predators or other hazards.
If a turtle is ON a roadway- then it can be quickly helped off the road! Please see our recent blog post about helping turtles on the road. If you do move a turtle off the road, never take the turtle to a completely new location. Finally, handle it as little as possible to reduce the risk of injury or disease for you and the turtle.
It can be exciting to see a turtle in the wild, and it may be tempting to continue to handle it or even take it home to keep as a pet; however, it is important to remember that they are wild animals and will live much better lives in their natural habitat than they will in a tank. In many cases, wild caught turtles do not adjust to captivity, as they do not react well to sudden space and dietary restrictions. Furthermore, only a small percentage of wild turtles survive to adulthood, so removing them from the population can be detrimental to that population’s future.
NEW, WEEKLY UPDATES FROM NEW JERSEY’S BEACH NESTING BIRD PROJECT TEAM
by Todd Pover, Beach Nesting Bird Project Manager
There are many ways to gauge success for our beachnesting bird project. We look at how well our management tools work, the effectiveness of our partnerships, and how well our educational efforts work, to name a few qualitative measures we use. At some point, however, it comes down to cold hard numbers, how well did the birds do in a particular season and over the long-term. We are at that point in the season, and for the most part, I am happy to report it has been an excellent breeding year. I will caution that these are still preliminary figures, some quality checking of the data needs to be done before they are final, but the trends are clear.

First up are piping plovers. We will come in at ~115 pairs statewide, up modestly from the 108 pairs in 2015, and the second consecutive year of an increase after hitting our historic low of just 92 pairs in 2014. So, we have climbed back closer to our long-term average, but there is still room to improve. The really good news is our productivity this year – close to a statewide record at 1.37 chicks fledged per pairs – puts us in the position to continue our population increase. If trends hold, because piping plovers demonstrate high site (or region) fidelity, when we produce a lot of fledglings, our breeding population rises in the next year or two. With three straight years of well above average fledgling rates for New Jersey now in the books, our prospects look good in the short term for our breeding population levels.
Least terns and black skimmers, which nest in colonies, sometimes numbering hundreds (or even thousands), are more challenging to count and assess, but we had at least modest success this year for both species. As is typical, our least tern colonies were variable, with some completely failing and others being highly productive. The Monmouth County region, one of our strongholds for least terns in New Jersey, didn’t have one colony that was a standout but most of them had at least some success. In South Jersey, our two largest colonies at Holgate (EB Forsythe NWR) and Seaview Harbor were very successful and helped make up for losses and failures at other colonies. The majority of our state’s black skimmers are concentrated in one large colony at Seaview Harbor, and although skimmers are our latest nesters (so the season isn’t quite over for them), they appear to have been very successful there, which means a good season overall for the state.
We also track American oystercatchers, although only for the portion that nest on the barrier beaches and spits. Because the biggest percentage of oystercatchers in the state nest on back bay and marsh islands, we cannot determine true statewide population or productivity levels, but the population on the beach habitat appears to be rising in recent years. Typically breeding success is lower for oystercatchers on the beach habitat due to high levels of human disturbance and predators, but productivity has been relative high the past two years. Of particular note this year was Stone Harbor Point, where a record number of 27 pairs nested and produced over 30 fledglings.
The reality is our beachnester staff works just as hard in years when the birds do poorly, as when they do well like this year, but it is SO much more rewarding when we have a good season. So as we wrap up the season, we are all feeling in a bit of a celebratory mode now!
NEW, WEEKLY UPDATES FROM NEW JERSEY’S BEACH NESTING BIRD PROJECT TEAM
by Todd Pover, Beach Nesting Bird Project Manager
For this week’s installment, I thought it would be fun to have you tag along with me on a day in the field, so you can get a sampling of what goes into our beach nesting bird program. Let’s call it, “A Day in the Life of a Beachnester.”

Today it is an early 4 am rise to beat the beach crowds and heat, as we are banding black skimmers at our Belmar colony. This is the first time our program has banded skimmers – it is a collaborative effort with other organizations/agencies in both New York and New Jersey – we hope to find out more about their survival, longevity, and movement, both local and long distance. Everything goes well, we are able to corral and band about 35 chicks in less than an hour. This part of the day represents the science portion of the beach nesting bird project, science for the sake of study and a better understanding of our birds, but more importantly to gather information to help us manage and recover endangered species.
With no time to spare, it is now off to Leonardo along Sandy Hook Bay where CWF is hosting a summer wildlife experience for kids. No surprise, I am the guest today to teach the kids about beach nesting birds. I explain why piping plovers and American oystercatchers are at risk, and then give them a chance to use a high powered birding scope to try to read bands I have placed on decoy birds. We definitely have some budding biologists in the mix. Education is key to our project, unlike other endangered species that mostly live out of sight or reach, beachnesters spend the breeding season on the same beaches visited by millions of tourists and residents. If they are going to learn to “share the shore” with our endangered birds, outreach is essential.

Next up is a stop at Seven Presidents Oceanfront Park, one of our important nesting areas in Monmouth County. For most of the season we are erecting and adjusting fence to protect nesting areas, but today we are working with the park to reduce the fence, as many of our birds have successfully nested and started to leave the area. First we count and locate any remaining least terns – these surveys are the base of our project – we need this data to track population trends and seasonal productivity as metrics of progress towards recovery. Before we remove any fence at this site, we also conduct surveys of sea beach amaranth, an endangered plant that shares the beach with our nesting birds. We locate a few plants and that dictates how we readjust the fence, the plants need protection from trampling by beachgoers or vehicles used by the park to maintain their beach.
Coordination with municipalities or other land owners that host beach nesting birds is a critical part of our project, as their activities can impact nesting success as much as beachgoer’s recreational use of the beach. So there is one more stop today to assess whether a maintenance request can be granted in a way that won’t put birds at risk. That done, it is time to start the two hour drive back to our office in Cape May County. I am ready for a nap, but no luck, as the truck becomes a mobile office to take care of other unattended business (while someone else drives of course). There are calls with several other towns, check-ins with our seasonal staff members that are spread out all along the coast, and finally dealing with a broken down vehicle (not ours fortunately) and a person who refused to take their dog off a nesting site.
Back at the office, it is one last check of email, entering a little bit of the data we collected today, and finally time to head home. Every day is a little different, but this day has been a good cross-section of the range of things we do on the project. It is tempting to think we just pop up fence and signs and hope the birds do well, but protection and recovery of our endangered beach nesting birds requires a comprehensive strategy addressing all the factors that impact nesting success.

ROADS ARE DANGEROUS CROSSINGS FOR SLOW-MOVING TURTLES
by Kathleen Wadiak, CWF Intern
New Jersey is home to a number of turtle species, and this time of year, it is not uncommon to see some of them crossing the road. Slow movers on land, they are not well equipped to avoid the dangers of a busy roadway. If you come across a turtle on one of your streets, what should you do?

First of all, it is important to think of your own safety in addition to the turtle’s. Be sure to pull completely over to the side of the road and to put on your hazard lights. Check for cars, and make sure that you are visible to oncoming traffic.

If you want to move a turtle across the road, there are a few things to keep in mind. To start, remember to never lift a turtle by its tail or limbs, as this can cause serious injury. With most turtles, it is best to pick them up on either side of their shell between the forelimbs and hind limbs. Even small ones may squirm and kick, so try to keep a firm hold and carry them low to the ground to avoid a dangerous drop!
If the turtle is large with a long tail and pointed head, it is likely a snapping turtle and should be met with some extra caution. Try using a blunt object to gently coax it to the roadside, and be careful to avoid touching it anywhere within range of its bite, which can reach as far back as the middle of its body! If you think you need to carry it, hold it with two hands on the shell behind its hind legs, on either side of the tail.

Before you handle a turtle, notice which direction it’s facing. Move it to that side of the street, as it is likely determined to head to a certain site, and will end up in the road again if it is moved away from its goal. This is an especially important point with the many threatened and endangered turtle species in our state. Helping turtles in trouble across a roadway and leaving them to enjoy their natural environment is a great way to ensure that there will be more wild turtles to appreciate for years to come!
BIG BROWN BATS ARE THE STAR OF THE SHOW FOR OVER 200,000 ONLINE FOLLOWERS
By Stephanie Feigin, Wildlife Ecologist
Earlier this week marked the second year that Conserve Wildlife Foundation of New Jersey wildlife ecologist Stephanie Feigin, along with project partner MacKenzie Hall from New Jersey’s Division of Fish and Wildlife and project interns from Rutgers University, banded the BatCam bats. This banding survey was part of a long standing maternity survey project conducted by CWF in partnership with NJDEP. These surveys allow us to gain important information about reproductive success, record weight, sex and age status of the bats, assess bats for signs of white-nose syndrome, and band bats for future observation.

This year, the team decided to stream the banding of big brown bats LIVE on Facebook. Allowing viewers to gain a once in a lifetime opportunity to see wildlife in a way they have never seen before and giving us the ability to directly interact with thousands of followers as we conducted an important wildlife survey. The banding has reached over 200,000 online followers as of Thursday morning.
The team caught and banded 36 bats total, 14 adult females (10 were recaputres from last year, 4 were banded as juveniles last year) and 23 juveniles (12 males and 11 female). All of the bats were weighed, measured, and banded according to the same coding as last year (red for juveniles and silver for adults).
The main goal of our Bat Project is to protect the bats we have in New Jersey, protect their habitats, learn more about their life cycles, and educate the public on the benefits of bats and how amazing and beneficial they truly are. By streaming live, we were able to shed new light on bats and allow the public to gain a better understanding for these special mammals.
GETTING A CLOSE-UP LOOK AT A BEAUTIFUL BUT ENDANGERED SONGBIRD
by Kathleen Wadiak, CWF Intern
Interning for CWF allows me to take part in a variety of projects and learn from different professionals working throughout the state. One example of this is the morning I was able to learn about golden-winged warblers through a mist netting survey. Honestly, I did not know much about this little bird until we were driving to a power line right-of-way early one morning, and I was given a quick summary of why it’s causing a stir in our home state.
The golden-winged warbler (Vermivora chrysoptera) is a striking little gray bird with black eye and throat markings, sporting a bright yellow head with matching wing patches. New Jersey serves as part of its breeding grounds throughout the summer, when it migrates north from its winter habitat in Central and South America. Unfortunately, its populations have been in decline, resulting in its classification as a state endangered species.

There are a few possible reasons for the decline in golden-winged warbler populations, including a decrease in their habitat, early-successional sites which consist of shrubby and herbaceous ground cover instead of mature forest. To the golden-winged warbler’s disadvantage, much of its New Jersey forest was cut at the same time, resulting in even-aged stands that are now too old to provide the nesting sites necessary for survival. Currently, golden-winged warblers occupy regenerating clear cuts, wetlands, or utility right-of-ways in northwestern New Jersey, where they can still find the resources that they need.
In addition to habitat loss, interactions with the closely related blue-winged warbler (Vermivora cyanoptera) are impacting the golden-wings’ numbers. It is thought that as climate change causes shifts in the geographic range of both species, more overlap between the two occurs. This results in increased competition for food, nesting sites, and even mates, as the two birds are closely related.
Walking through the high grass under the powerlines, we stopped now and then to listen to birds singing and look for golden-wings. While my untrained ears had trouble differentiating between all of the different calls, a biologist with NJ Audubon confidently told us where to begin setting up each net. After the net was raised, different recordings meant to attract the warblers played while we stepped back and waited hopefully for the right birds to come.

It was exciting to see the first birds fly into the net and to have the opportunity to view them up close, even if they weren’t always the ones we were looking for. While we set up three nets throughout the morning, our first attempt was most successful as it resulted in the capture of one of the rare golden-winged warblers! Its banded leg told us that this wasn’t its first time in a net, and that it had been to this site in the past, a good sign for this particular stretch of habitat. Its dramatic markings and flashes of gold feathers made it a beautiful bird, and it struck me what a shame it would be if they disappeared completely from our state.
While things are tough for golden-winged warblers in New Jersey, hope is not lost as many organizations, including CWF, the Natural Resources Conservation Service, NJ Audubon, and NJ Division of Fish and Wildlife are working to keep these birds in the Garden State. Mist netting and banding the Golden-wings allow biologists to track the number and location of these warblers throughout their breeding grounds and aid in the creation of management strategy. In addition, there is an effort to educate private landowners about golden-wings and to help them manage their property in a way that attracts the birds. Hopefully, as this work continues, more land will be suited to their habitat preferences, and golden-winged warblers will return to their summer homes in New Jersey.
