A Partnership of Herpetologists

Tuesday, August 8th, 2023

by Christine Healy, Wildlife Biologist

It’s always fun to learn the collective names for groups of animals. For example, in the amphibian and reptile world, we have an army of frogs; a congress of salamanders; a bale of turtles; and a lounge of lizards. I wonder what quippy term could describe a group of herpetologists- the folks who spend their lives studying the armies, congresses, bales, and lounges? Perhaps… a partnership?

In that case, a partnership of herpetologists from as far south as Virginia all the way up to Maine descended upon Middletown, Connecticut last month. Not to cross some rare species off their life list (though coincidentally, I crossed two off mine), but rather to attend the annual Northeast Partners in Amphibian and Reptile Conservation (NEPARC) conference, hosted at Wesleyan University.

That’s a Wrap for the Pilot Season of a New Collaborative Project with NJDEP Focusing on Pine Barrens Tree Frogs

At quick glance, Pine Barrens tree frogs (PBTF), with their vivid green backs, deep purple sides, and vibrant yellow thighs, might put folks in mind of Central and South American rainforests. Based on their visage, they could, theoretically, be at home beside red-eyed tree frogs and poison arrow frogs – the poster children of amphibian diversity. They have occupied that spotlight themselves. In fact, in his 1983 Endangered Species series, American pop artist Andy Warhol chose to immortalize the PBTF in silkscreen as the lone representative of herptiles. But these tiny beauties do not favor the tropics. Occurring in three disjunct populations across the eastern United States including the Florida/Alabama panhandle, the Carolinas and, naturally, New Jersey, PBTF are habitat specialists. They reside in seepage bogs where the water is relatively acidic, due to the presiding vegetation. Sadly, as is the case with many animals reliant on very specific landscape features, habitat loss and fragmentation pose a concern for the persistence of this species, which is listed as threatened in New Jersey.

CWF is very excited to be partnering with NJDEP, Division of Watershed Protection and Restoration on a long-term study aimed at better understanding the effect of development on vulnerable species. We will measure abundance, adult health and survival, and larval growth of Pine Barrens tree frogs within a population impacted by encroaching construction to evaluate whether current wetland regulations, including buffer size, are sufficient for species conservation.


Star Ledger: The Endangered Species of NJ

NJ Advance Media reporter Michael Sol Warren highlighted 17 endangered species in an insightful story looking at what can be done to save New Jersey’s rare wildlife. Conserve Wildlife Foundation has long focused on many of these species – from the piping plover and the bobcat to the bog turtle and the Pine Barrens tree frog – through monitoring and surveys, habitat restoration, and public engagement.
