This summer I had the opportunity to work as an intern for the Conserve Wildlife Foundation of New Jersey (CWF), researching and surveying Northern diamondback terrapins. Words could not describe how excited I was for this position, working with Senior Wildlife Biologist, Ben Wurst every day this summer was an incredible learning experience. Mr. Wurst taught me how to conduct surveys Great Bay Blvd Wildlife Management Area. This area is an ecological marvel, I witnessed hundreds of terrapins crossing the road on multiple occasions. I remember one day in particular when such a large quantity of terrapins were moving that it took me six hours to drive down that five-mile road, over two hundred terrapins were observed on Great Bay Boulevard that day alone.

This summer, I had the chance to volunteer for the Great Bay Terrapin Project to help survey the local terrapin population within Great Bay Boulevard Wildlife Management Area. Being able to assist a vulnerable population was incredibly fulfilling and I personally was able to learn a lot about their behavior during this incredible time. I got to see firsthand just how many female turtles crossed that road to lay their eggs, but unfortunately that also showed me just how many were injured or killed by reckless, inattentive, or outright malicious drivers. One thing I realized during this is just how hardy of an animal the terrapin is. I saw individuals with massive chunks taken out of them, bite marks, claw marks, and huge gashes from boat propellers forever etched into their shells. I realized that despite their vulnerability in early life and extremely slow growth, the defense of their shell and their insane ability to recover from injuries left them with very few threats for a long time. Even many major boat injuries are recoverable, emphasizing the severity of the threat posed by automobiles specifically.
Since 2021, Conserve Wildlife Foundation of New Jersey (CWF) has been partnering with New Jersey Audubon (NJA), New Jersey Conservation Foundation (NJCF), the United States Fish and Wildlife Service (USFWS), and New Jersey Fish and Wildlife (NJFW) on bog turtle conservation in Salem County. Though densities in the southern part of the state are understood to be lower than in north Jersey, conserving this metapopulation is a priority as bog turtle numbers continue to decline despite long-term state (endangered since 1974) and federal (threatened since 1997) protections. A primary driver of this decline is habitat loss- but not necessarily in the way you might expect. The shift in plant communities- from grasslands to forests- occurs naturally over time. We call this process “succession”, and it can be both a gift and a curse.
Under normal circumstances, Mother Nature sometimes throws a wrench in the plans of mid- and late-successional species (like oaks and maples, respectively), in the form of disturbances. Beaver activity may cause flooding that inhibits tree growth. Natural fires in healthy forests can thin trees enabling the understory to receive enough sunlight to persist. These burn slower and cooler than wildfires. Some trees, like the longleaf pine in the southern US, even require fire in order to rejuvenate. In some cases, large mammals may eat or break saplings before they have a chance to establish. This apparent “destruction” is actually a good thing- disturbances like these are why we have meadows and prairies. A mosaic of habitat types that run the spectrum of open wetlands to old-growth forest, is key to a high diversity of wildlife.
Etiquette tells us that we shouldn’t have a favorite child. I sometimes wonder if the same rules apply to biologists with regard to our study species. If so, my manners fall woefully short, at least where reptiles are concerned.
Conserve Wildlife Foundation has been partnering with the United States Fish and Wildlife Service (USFWS) on bog turtle conservation initiatives for years. We do this using a multi-faceted approach. We connect landowners with qualifying habitat with federal funding opportunities and technical support that can preserve and restore significant wetlands. We assist the state and nonprofit partners with visual surveys to better understand the status of historic populations. Finally, we suit up with USFWS personnel each fall and winter to remove invasive species and woody vegetation that are shading out nesting spots, rendering bogs and fens inhospitable to turtles. We applied to continue this work for the next few years but decided to shake things up a bit by adding in tasks targeting the protection of the bog turtle’s closest living relative… the wood turtle, a state threatened species that is currently under consideration for federal listing.

Although I spend much of my time thinking about reptiles and amphibians, if you were to ask me if I could be classified as a “herper”, my immediate answer would be no. When I go for hikes, my objective is to reach the summit and take in the view- I’m not generally looking to offroad and go slow. I recently compiled a list, however, of all the herps that I have found during my outdoor adventures this year and was shocked to realize that I’ve encountered 31 species of wild turtles, snakes, frogs, and salamanders. Of those, I had the intention of locating 13 as part of my seasonal field assignments for CWF- the rest were all incidental finds. Moreover, despite the period in question being rather lengthy, it was very easy for me to parse apart which species were really 2023 observations versus some other year. And I can recall where I was and what the individual was doing in each case.
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.

July 16th is World Snake Day! This day of recognition was established to increase awareness and raise appreciation for these most polarizing of creatures. People tend to have an extreme opinion when it comes to snakes; They are loved and revered by some, loathed and vilified by many. Mythology, religion, and pop culture are riddled with snake imagery and, though these media sometimes align them with healing, transformation, and fertility, they often proliferate a connection between them and evil intentions. Whether learned or not in Greek legend, the Medusa, with her living locks, is universally recognizable and her beheading is counted among the greatest achievements of the hero, Perseus. Norse stories give us Jörmungandr, the serpent son of Loki, hated by and responsible for the death of his uncle, the beloved god Thor. The Bible symbolizes the devil himself as a snake in the Garden of Eden and, in this form, provides the temptation responsible for original sin in Christian teachings. More recently, we watched as ophidiophobia (fear of snakes) became the Achille’s heel of everyone’s favorite archeology professor, Indiana Jones, and read about how the ability to communicate with snakes was a defining characteristic of Lord Voldemort, the most notorious dark wizard of all time. To be clear, I’m not suggesting that works such as these are responsible for a negative public perception of snakes. Rather, I think they capitalize on a rampant unease associated with snakes to encourage their audience to sympathize with the protagonist. The truth is, snakes can be dangerous, particularly if they are venomous. Snakes can and do kill people, sometimes stealthily, which defies our view of humans as the universal apex predator. This, naturally, instills anxiety. But it’s also not the full story.
Coverboards are typically placed along ecotones, where species diversity is expected to be greatest. The corrugated tin board, pictured above, was positioned along a forest edge where larger deciduous trees meet a more open, sandy landscape.
How do you survey for animals that spend most of their time hidden under leaf litter or wedged between fallen tree limbs and rocks?
In the case of reptiles and amphibians, the answer is to use coverboards!
Coverboards are materials that are intentionally placed within a potential habitat, often along ecotones (where different habitat types- e.g., wetland and forest, field and forest, etc. come together) that trap moisture and retain heat, creating favorable conditions for our “cold-blooded” (ectothermic) friends. Researchers often arrange coverboards in long transects or arrays and collect data on the diversity of the community underneath the boards as compared to the surrounding environment. This technique was used by NJDEP Division of Fish and Wildlife to survey for herptiles in 17 wildlife management areas in the early 2000s (Golden, 2004). A total of 30 species were recorded during the first year of the study, including long-tailed salamanders, pine barrens tree frogs, and northern pine snakes, all of which are listed as threatened in New Jersey.

If you live here at the Jersey Shore then there is a good chance you have seen a turtle or two trying to cross the road. This project ”turtle gardens” is located on the bay in Little Egg Harbor Township on Seven Bridges Road. The purpose is to give area turtles a place to lay eggs that’s out of harm’s way.
This is a fantastic project to help turtles which often are hit by cars trying to find areas to lay eggs. You may have seen signs around the Jersey Shore ”turtle crossing” to alert you to watch for turtles on area roadways usually late spring through summer.
Northern Diamondback Terrapins (Malaclemys terrapin terrapin) are a native species of New Jersey turtle, inhabiting the brackish waters of the state’s coastal salt marshes and estuaries. The survival of the species depends on the ability of female turtles to access safe nesting habitat every summer, a struggle for the species these days with roadways disconnecting large swaths of their habitat. To help give females a better chance of successfully reproducing, CWF partnered with New Jersey Division of Fish & Wildlife last year to create a half-acre “turtle garden” at a former marina within the Great Bay Wildlife Management Area.
CWF Habitat Manager Ben Wurst took Pat Johnson of TheSandpaper.net to the site recently to survey the success of this new turtle garden and walk through what it takes to save a species like the diamondback terrapin.
Check out the except below!
It’s diamondback terrapin hatching season in the newest turtle garden established by the Conserve Wildlife Foundation of New Jersey in the Great Bay Wildlife Management Area. Project Manager Ben Wurst has been monitoring the 50 or so nests that were created this spring to protect them from predators so the hatchlings could have a fighting chance of survival.
