Dedicated volunteers help reduce mortality of adult female terrapins
by Ben Wurst, Habitat Program Manager
Volunteers Elizabeth and Courtney measure the height of a female terrapins carapace.
Now that Northern diamondback terrapins (Malaclemys terrapin terrapin) are officially considered a nongame species, our work to help conserve breeding adult females is more justifiable. Before July 2016, adult terrapins, including egg bearing females, could be harvested during an open season from November to March. With that said, it was troublesome to know that a 15+ year old female that you helped safely cross a road in summer, could be harvested, shipped to Asia and eaten only a few months later… Now, we can rest (somewhat) easy knowing that the hard work of our dedicated volunteers will live on and help the population grow (there are still many threats to terrapins including collisions with boats, vehicles, poaching, drowning in ghost crab pots, etc…) Continue reading “Reducing Roadkills of Terrapins in S.

The salamanders and frogs in East Brunswick got an early start to their migration season by crossing this week on February 15. David Moskowitz found spotted salamanders, wood frogs, dozens of spring peepers, and one wood frog crossing the temporarily closed section of Beekman Road in the early evening rain.
“This is the earliest they’ve ever moved – by about a week – in the 12 years I’ve been closing the road,” said Moskowitz.
East Brunswick has closed the road for a few nights each late winter/early spring when conditions are just right. While all amphibian species are vulnerable, spotted salamanders are a species of special concern in New Jersey.

Conserve Wildlife Foundation partners with certain municipalities and the Division of Fish and Wildlife’s Endangered and Nongame Species Program on salamander crossings in northern New Jersey. This is a key initiative among CWF’s amphibian projects.
The East Brunswick crossing offers the best opportunity for the public to take part and see these salamanders and frogs up close. Check their website for the next expected crossing and share the road with a salamander!
Each New Year promises an exciting year ahead, and conservation science is no exception! As biologists gear up for the field season, CWF’s amphibian programs are particularly noteworthy.
Our Amphibian Crossing Project has made major strides in protecting the frogs, toads, and salamanders migrating to breeding areas, and we’re launching a new program this year to better document the newly discovered mid-Atlantic coast leopard frog. You can help CWF biologists collect data and save these fragile creatures.
Read below for more details about each program. In the meantime, if you would like to support CWF’s amphibian programs, please visit our YouCaring page here: https://www.youcaring.com/conservewildlifefoundationofnewjersey-1091698 . Your contribution will help us develop training materials and cover research expenses to protect our most vulnerable frogs and salamanders!
Amphibian Crossing: A New Twist on an Old Program
The long-standing Amphibian Crossing Project, established in partnership with the New Jersey Endangered and Nongame Species Program (ENSP) in 2002, has been organizing dedicated volunteers each spring to chauffer migrating amphibians across roads as they trek from their upland hibernation sites to their breeding ponds. This program has saved thousands of frogs, toads, and salamanders from vehicle strikes so that local amphibian population sizes can be maintained, which is especially important for species of concern, such as the Jefferson and spotted salamanders.
Seeking a more long-term solution to the amphibian road mortality problem at the Amphibian Crossing Project’s top site, ENSP has finally secured funding to construct crossing structure system for amphibians to move safely across Waterloo Road in Byram Township, Sussex County. This system, including under-road tunnels and guide fencing, will help amphibians avoid problems on the road all season long. CWF is preparing its second year of monitoring along Waterloo Road to track the changes in amphibian vehicle-caused mortality before and after this system is installed.
Leopard Frogs: A New Program for a New Species
This year marks the launch of CWF’s Kauffeld’s Calling Frogs program. Similar to New Jersey’s Calling Amphibian Monitoring Program (CAMP), volunteers will listen and document frog calls during the breeding season. Kauffeld’s Calling Frogs, however, will focus specifically on the newly discovered mid-Atlantic coast leopard frog. This frog, named after the late avid herpetologist Carl Kauffeld, had been mistaken as a member of the southern leopard frog species for decades. Only recently was it determined to be a separate species with unique habitat requirements.
Despite only being an official species since 2014, it is already considered a Species of Greatest Conservation Need in New York, and may be declining from other portions of its range. CWF biologists are eager to document the current extent of this frog’s range within New Jersey in order to monitor the population for possible declines. Knowing where this species is found is the foundation for future research into its habitat needs and threats.
Getting the Public Involved
These amphibian programs cannot move forward without the dedication of CWF volunteers. Over 100 volunteers have been involved with the Amphibian Crossing Project, and a dozen more dedicated at least a day a week for months to monitor Waterloo Road amphibian mortality. With the success of CAMP in mind, this first year of Kauffeld’s Calling Frogs promises to be full of new frog population discoveries.

Just in time for next week’s Great Backyard Bird Count, The (Bergen) Record’s Jim Wright takes a look at the hairy woodpecker with help from CWF Executive Director David Wheeler. This backyard birdwatching favorite is still a common sight on many New Jersey feeders and tree trunks, but remains vulnerable nationally due to its nesting reliance on old tree snags.

How CWF Is Fighting This Threat to Wildlife in Barnegat Bay
by Emily Heiser, Wildlife Biologist
For many coastal communities in New Jersey, like the Barnegat Bay region, winter is a time for rejuvenation and the preparation of our resources for a busy summer season. It only makes sense that we also start to prepare the coast’s most precious resource – the bay.
Barnegat Bay is approximately 42 miles of brackish marsh and bay bordering Ocean County. The bay and surrounding marshlands are rich in vital resources that directly and indirectly support over 60,000 jobs and have an economic value of $2 to $4 billion dollars annually (Barnegat Bay Partnership Economic Report 2012).
Pots are often heavily encrusted with organisms and can contain several different species of bycatch. @ John Wenk
Part of that economic value is attributed to the tremendous blue claw crab fishery in the bay. The New Jersey Division of Fish and Wildlife estimates that commercial and recreational crabbers harvest around 6 million crabs per year from New Jersey waters. Barnegat Bay, along with Little Egg Harbor and the Maurice River estuary comprise approximately 65-86% of the recreational harvest that occurs annually. Recreational crabbers use a variety of methods, but typically rely on baited pots or hand lines for crabbing. Regulations exist for the use of pots, but their unintentional loss has created an economic and environmental problem for all portions of Barnegat Bay.
CWF, along with our partners, has been diligently organizing and executing what is essentially a cleanup of these pots within Barnegat Bay. In 2015 and 2017, CWF was granted a NOAA Marine Debris Removal Program grant to support the removal of derelict crab pots, also know as ghost pots, from Barnegat Bay. Over the course of the last three years, we have removed over 1,300 crab pots that have become a death trap for a variety of marine organisms, including diamondback terrapins and otherwise fishable blue crabs.
Students from the Marine Academy of Technology and Environmental Science assist in assessing pots after they’ve been pulled from the bay. @John Wenk
All of the fieldwork on this project occurs during the chilling winter months when only the hardiest of fishermen can be found on the water. The blue crab season is open in most parts of the state from March 15th – November 30th leaving the coldest months to head out and collect pots that are not supposed to be actively fishing. Several partners have made this project a possibility – the Marine Academy of Technology and Environmental Science, Stockton University, Monmouth University, ReClam the Bay, American Littoral Society, and through contracts with local fishermen.
Using side-scan sonar units, crews head out in early December to start looking for ghost pots. Once a sufficient number of pots have been marked, waypoints are transferred over to retrieval crews. Retrieving the pots sounds easy in theory, but can be time-consuming and success is dependent on many compounding factors such as substrate, weather, and tidal conditions. Upon relocation of a surveyed pot, the captain must line the boat up to the best of their ability and with as much accuracy as they can, instructs the crew where to throw the grapple line. Often you hear them call out, “Five feet – left center” and amazingly, the crew throws the grapple and hooks into a pot! Depending on the substrate and how long the pot has been on the bay floor, it can be very difficult and dangerous to leverage out. With the use of just the right amount of engine power, sunken pots can be delicately coaxed out of the water and lifted onto the boat by crews. Once a pot is on the boat, a rapid assessment is done to look for unintended bycatch, pot design, and encrusting organisms. Some of the various bycatch that has been found in pots include several species of crabs, lobster, flounder, tautog, and sadly, several diamondback terrapins. One pot contained the remains of more than 17 diamondback terrapins.
Ghost pots are disposed of by NFWF and Covanta’s Fishing for Energy Program where they will be recycled and turned into energy. @John Wenk
After a day of retrievals, the crew heads back to the marina where pots are placed in a disposal bin. The bins are provided to the project through the successful Fishing for Energy Program run by National Fish and Wildlife Foundation, Covanta Energy, and Schnitzer Steel. Gear collected from our port is stripped for recyclable materials at Schnitzer Steel and then non-recyclable material is turned into energy at Covanta’s facility in Rahway, New Jersey. The holistic nature of this project breathes life into the term, “reduce, reuse, recycle”.
Barnegat Bay’s ghost pots exemplify an overarching issue of our environment, human-wildlife conflicts. The Bay’s vital resources drive the economy and addressing these issues make us better stewards of the Bay and its resources.
Our Work isn’t Done – the Ongoing Importance of Band Resighting
By Todd Pover, Senior Wildlife Biologist
Earlier in January, I attended the Abaco Science Alliance Conference to make a presentation about recent conservation and research developments for piping plovers in the Bahamas. This marks the eighth year, starting in 2011, either solo or with CWF staff and other colleagues, that I have been able to follow piping plovers to their wintering grounds in the Bahamas to conduct work to better understand and help recover this at-risk species. And in another sense, to be an international ambassador for piping plovers.
Todd Pover, CWF Senior Biologist, busy searching for piping plovers on the flats in the Bahamas
Over that time, the focus of those trips has varied widely, including conducting surveys for the International Piping Plover Census in 2011 and 2016, improving our understanding of how piping plovers use the various habitats, engaging students with our Shorebird Sister School Network from 2014-17, helping Friends of the Environment, our primary partner there, integrate piping plovers into their educational/school programs, building conservation partnerships, and even producing a video. Tremendous positive changes have occurred in that time with regard to awareness of and attitudes towards piping plovers in the Bahamas and some significant conservation progress has been made, most notably the establishment of several new national parks by the Bahamian government that help protect piping plovers and other shorebirds.
CWF’s bald eagle project was featured in a news feature today on New Jersey 101.5 FM.

January kicks off bald eagle nesting season in the Garden State, and biologists from CWF and the Endangered and Nongame Species Program are working with volunteers across the state to monitor the nests of approximately 150 bald eagle pairs – up from 1 nesting pair just a few decades ago!
Statewide Census Documents over 650 nesting pairs in New Jersey
by Ben Wurst, Habitat Program Manager
An osprey prepares to land on a natural nest. Barnegat Bay, NJ.
Since we began to work more closely with ospreys in 2006, we have documented the population grow beyond the historic population estimate of 350-450 nesting pairs (Henny 1977) to a new historic milestone. In 2017, a total of 668 active nests were recorded during a statewide census of nesting ospreys, which is well above the post-DDT milestone of 500 nesting pairs, and show that the population continues to grow. This is the second census conducted without the use of manned aircraft since 2009 after all known osprey nests were released and mapped online in 2013. Despite the lack of aircraft, we’re still able to obtain an accurate representation of the size and health of the statewide population, while reducing the overall project cost. Continue reading “Osprey Numbers Surge Above Post-DDT Milestone”
CWF will be at the festival on February 3rd. There are presentations, walks, viewing sites and exhibitors. It’s a great way to learn about NJ’s eagles and other raptors.
These amphibian programs cannot move forward without the dedication of CWF volunteers. Over 100 volunteers have been involved with the Amphibian Crossing Project, and a dozen more dedicated at least a day a week for months to monitor Waterloo Road amphibian mortality. With the success of CAMP in mind, this first year of Kauffeld’s Calling Frogs promises to be full of new frog population discoveries.
