Exploring New Jersey’s Amphibian Migrations

by Leah Wells, Wildlife Biologist

Wood Frogs

 On rainy spring evenings, have you ever encountered large numbers of salamanders and frogs crossing the road? Do you ever wonder where they came from and where they are going? New Jersey’s forests are home to a group of amphibians that breed in small, temporary wetlands called vernal pools. Within northern New Jersey, this group includes wood frogs, spotted salamanders, and Jefferson salamanders. 

These salamanders are elusive, often concealed under foliage, moss, or in burrows created by small creatures.  They belong to the Ambystomatidae family, earning the nickname “mole salamander” due to their subterranean tendencies. Feeding primarily at night on various invertebrates like earthworms and insects, they, along with wood frogs, play crucial roles in forest ecosystems as vital links in the food chain and are indicators of ecosystem health. Emerging from winter hibernation during rainy nights in late winter and early spring, they embark on journeys to vernal pools for mating and egg-laying, marking the onset of the amphibian migration.

2024 Species on the Edge Art & Essay Contest Winners Announced

by Rachel McGovern, Director of Education

For more than twenty years, Conserve Wildlife Foundation of New Jersey has been organizing the Species on the Edge Art & Essay Contest, inviting all fifth graders in New Jersey to participate. This year marked another successful run, with an array of imaginative and captivating submissions pouring in from all twenty-one counties. Each entry examined the plight of a threatened or endangered species native to New Jersey.

To take part in the Species on the Edge Art & Essay Contest, students must craft an original piece of handmade artwork and compose an essay responding to a provided prompt. Both components of their submission center around a single at-risk species from New Jersey. We typically find that some species are represented more than others. This year, the golden-winged warbler stood out with numerous striking artworks spotlighting this bird. Other frequently chosen species included the blue whale, bobcat, and red-headed woodpecker.

Encouraging Development for Tiger Salamanders

By Christine Healy, Wildlife Biologist

In today’s world, it’s pretty difficult to think of a species that scientists are not concerned about in the face of climate change. The reasons are many and diverse, but in a state where 42% of municipalities are considered “coastal”, it comes as no surprise that sea level rise (SLR) is a big threat here- both to people and wildlife. When the average person imagines which species are most likely to be impacted by SLR, it’s likely that beach nesters, including piping plovers, immediately come to mind. Afterall, they occupy the same environments that recreationalists are worried about losing. Valid point- but they are not the only ones. Eastern tiger salamanders, one of New Jersey’s rarest amphibians, also make the list. 

Like our other mole salamanders (spotted, blue-spotted, marbled, and Jefferson), Eastern tiger salamanders require access to temporary wetlands, called vernal pools, to successfully breed. The ephemeral nature of these water bodies is critical because it eliminates fish as potential egg predators and thus increases larval survival. While these salamanders spend much of the year in forested landscapes, adults return annually to their natal pools (in most cases) to reproduce. High fidelity to these sites can put these amphibians in danger if development occurs within their migration corridors or changes transpire within the pools themselves.

A Return to Barnegat Light to Get the Beach Ready for Plovers

by Todd Pover, Senior Wildlife Biologist

Winter maintenance of the Barnegat Light habitat restoration site is a key element in the project’s success to benefit New Jersey’s piping plovers and other beach-nesting birds. The original project – clearing about 40 acres of dense beach vegetation and dunes to create an early-successional habitat favored by plovers and adding “ponds” to create foraging opportunities – was completed over two winters in 2019 and 2020. Each winter since, we have returned to the site for a short period, typically a week or so, to thin vegetation and reestablish foraging habitat along the pond edges in advance of nesting birds returning for the season.

This year was no exception, I was on-site in late January and early February to guide a bulldozer operator to prepare the site for plovers. Although the maintenance work we do each year is similar, the details and nuances of it vary quite a bit. Last winter, for example, one of the foraging ponds was completely sanded over from fall and early winter storms, so we spent most of the time re-digging that. This year, the ponds were in much better shape, so we had more time to focus on clearing out thick vegetation that had crept back into the site to improve the nesting substrate.

Highlights of a Recent Mammal Inventory

by Meaghan Lyon, Wildlife Biologist

In the spring and summer of 2023, CWF set up over 100 field cameras in a variety of habitats along mammal travel paths at the Joint Base in Lakehurst. The study captured a glimpse of what wildlife does when they think no one is watching.

To start, here is an abbreviated species list of most of the wildlife captured on camera. We were not surprised to find that nearly 80% of our captures were of white-tailed deer! Unfortunately, no captures of black bears have been reported in the area in previous years. Check out some of the captures below!

  • White-tailed deer
  • Red fox
  • Grey fox
  • Coyote
  • Striped skunk
  • Opossum
  • Beaver
  • Groundhog
  • Eastern grey squirrel
  • American red squirrel
  • Southern flying squirrel
  • Raccoon
  • Eastern cottontail rabbit
  • Mice species
  • Domestic cat
  • Great blue heron
  • Wild Turkey
  • Owl species
  • Songbird species
