Each year in the early spring, piping plovers migrate north to their breeding range, which spans from North Carolina to the Canadian island of Newfoundland. The New Jersey coastline has historically been integral for breeding birds to forage and raise chicks, although suitable habitat is becoming more and more of a rarity in the state. The increase in development, as well as the impact of storms, shoreline erosion and climate change, have permanently altered much of the Jersey shore. Nesting habitat for beach-nesting birds is limited, and predators with exploding populations benefiting from human presence along the coast, make their homes among the beach vegetation and nearby man-made domiciles. Natural beaches with minimal recreational usage are extremely valuable for beach-nesting birds in NJ, with most located along the southern shores. However, some Monmouth County beaches like the National Guard Training Center beach in Sea Girt, are managed to protect the natural resources that are present and continue to host nesting plovers annually. 

The NGTC beach is monitored throughout the year by Conserve Wildlife Foundation biologists assigned to the duty as part of the Integrated Natural Resources Management Plan for the site, established by the NJ Department of Military and Veterans Affairs (DMAVA). Included in that plan are various surveys, practices and regulations designed to protect vulnerable species and habitats on the site while still allowing public recreation and beach maintenance to occur. The south half of the beach is a popular bathing beach that is free to military, veterans, police, and their families. The north half is primarily designated as natural beach where recreation is not encouraged. Piping plovers have nested in the Northern Protection Area for the last four years, from 2019 to 2022, with the same resident pair returning each year to reclaim their territory. Piping plovers “Joey” and “Hamlet” had a bitter end to their long-term relationship last year when Hamlet was found deceased, likely killed by an avian predator. Joey attempted to renest with a new female he met later in the season but was unsuccessful. Eventually, both birds moved on. However, given that he survived his winter retreat, Joey may return to the NGTC for 2023 and try to attract a new mate.

Terrapin hatchlings and 3000 tons of sand.

by Ben Wurst, Habitat Program Manager

While out inspecting our newly created terrapin habitat enhancement site in Little Egg Harbor, I found several terrapin hatchlings who were traversing the 36″ high pile of sand. I was expecting to see some hatchlings, since many arise from the protection of nest cavities on warm spring days in April, but not on top of our enhancement site. The moment I spotted one of these half dollar sized turtles, I looked into the distance and saw another.

Waterloo Village in Byram Township, Sussex County is more than a tourist attraction and local gem, it is also home to the largest cross-road amphibian migration in New Jersey. Each spring, frogs, toads, and salamanders stir from their hibernation to make their way to their breeding sites. Some of these sites, like the one at Waterloo, are vernal pools – small, temporary bodies of water that appear in early spring as snow melts and rain and groundwater gathers, and disappear throughout the summer as they evaporate. The ephemeral nature of these pools can’t support fish, which would prey on amphibian eggs and larvae. Vernal pools therefore provide some protection for amphibian offspring, with many species such as wood frogs and spotted and Jefferson salamanders – both of which are listed as New Jersey species of Special Concern – relying exclusively on these vernal pools for breeding.

 

 

The greatest challenge for amphibians breeding at Waterloo Historic Village is crossing Waterloo Road. Living in the most densely population state takes a toll on many species of wildlife in the form of habitat loss, degradation, and fragmentation. Each year, many amphibians become victim to vehicular collision as they move from their hibernation sites across Waterloo Road to the vernal pool in which they reproduce. Amphibians may be disproportionately affected by vehicle-caused road mortalities compared to other wildlife because of their tendency to migrate en masse to breeding sites. These annual road mortalities can have devastating effects on amphibian population sizes, especially for the local at-risk salamander populations. In fact, as little as about 10% annual risk of road mortality in spotted salamanders can lead to the local extinction of an entire population.

 

To address this problem, the Conserve Wildlife Foundation of New Jersey (CWF) and the New Jersey Endangered and Nongame Species Program (ENSP) organized amphibian rescue efforts. Since 2002, dedicated volunteers have assisted frogs, toads, and salamanders across Waterloo Road during the busiest migration nights. This aid has proven effective in reducing amphibian road mortalities, but it is not a permanent solution to the problem. Efforts are underway to construct under-road tunnels to help guide amphibians safely across Waterloo Road. These tunnels will provide safe passage for these critters throughout the breeding season, including on their migration back into the woods where they will hibernate. Since this return migration is more sporadic and less weather-dependent than migration to the vernal pool, it is much harder to protect amphibians as they make their way back to the forest.

 

 

This year, CWF scientists have begun the initial phases of research to understand current amphibian population sizes and the impact of vehicle traffic on these animals at Waterloo. Scientists and volunteers have been out 7 days a week since amphibian migrations began in late February to tally daily roadkill on Waterloo Road. This study will be used to evaluate changes to frog, toad, and salamander populations as the under-road amphibian tunnels are installed. CWF scientists have also conducted egg mass counts in the vernal pool at Waterloo Village to estimate the current population sizes of the different amphibian species in the area. Having this knowledge will allow CWF to improve on future projects to minimize road-related human-wildlife conflicts.

 

Along with improving conditions for amphibians in this location, CWF’s work at Waterloo Village will serve as an example of New Jersey statewide initiatives to reconnect wildlife habitat as a part of the Connecting Habitat Across New Jersey (CHANJ) program. The goal of CHANJ is to make our state landscapes more permeable to wildlife movement so that all of New Jersey’s residents – human and wildlife – will have the space they need to thrive.

 

In an effort to bring people and wildlife together in a positive way at Waterloo Village, CWF scientists are leading educational walks for the public and local schools. Through hands-on interaction, local residents can learn about and appreciate the remarkable wildlife right in their own back yards and what they can do to support conservation efforts.

 

All New Jerseyans can help wildlife this season by planting native plants for their gardens, building bat boxes where bats can roost, and, of course, by keeping an eye out on the roads, especially on warm, rainy nights when amphibians might be migrating.

Our Team is using Science-based Methods to Elevate the Marsh and Restore the Balance of High and Low Elevation

by Lindsay McNamara, Communications Manager

To restore Thompsons Beach, along New Jersey’s Delaware Bayshore, our team removed debris from the beach, removed rubble from the road leading to the beach, and placed over 40,000 cubic yards of sand (weighing over 9 million pounds) onto the beach. We were filled with pride when we saw sanderlings and ruddy turnstones feeding this August on horseshoe crab larvae on our newly restored beach. We were delighted to learn that this spring, Thompsons Beach had the highest abundance of horseshoe crab egg clusters out of all the beaches that our team monitors on Delaware Bay.

 
How do we keep the momentum going? How do we ensure our restoration work at Thompsons Beach yields long-term, sustainable results? The answer is clear: we protect the backbone that the beach sits on — the salt marsh behind the beach.
