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.

If you said Jersey Girl, then you’d be correct! Coincidentally, that’s also where volunteers and supporters alike gathered last month to show their love for amphibians. Jersey Girl Brewing in Mount Olive, that is.
Two years ago, we partnered with Jersey Girl to host a trivia event to raise awareness for our Amphibian Crossing Project, an initiative that seeks to reduce mortality among populations of frogs and salamanders whose migratory pathways are bisected by roadways. We chose the location based on its proximity to our largest crossing site, Waterloo Road, in the hopes that many of our hardworking volunteers could attend. We had a great turnout and a lot of fun. Following several requests, we decided to bring it back this year for round two.
Participants, including former CWF intern, Nicole Bergen (who helped write and host our first trivia event) pause during answer deliberation to smile for the camera.
Lots of familiar faces were in the crowd at Jersey Girl, including CWF’s Founder, Linda Tesauro, trustees Steve Neumann, Rick Weiman, and Amy Greene, former amphibian crossing leads MacKenzie Hall and Allegra Mitchell, former CWF intern, Morgan Mark, and many new and seasoned volunteers, like Barb and Rick McKee, without whom, this project could not succeed.
In the May 16th blog, Shorebird Stewards On the Bay in May, it’s mentioned that some beaches along the Delaware Bay have restricted access every year from May 7th to June 7th. This is due to the migratory shorebirds that travel thousands of miles and need a place to stop to feed. Our beaches contain excellent food sources to help birds gain weight to continue their journey- horseshoe crab eggs. They are filled with fat and protein. The Delaware Bay is the largest spawning area for horseshoe crabs in the world!
Now what do the Shorebird Stewards, such as myself, do all day? We monitor our assigned beaches and educate the public about this incredible phenomenon! My favorite beaches are Roosevelt Blvd. beach and Cook’s Beach because I see the most active flocks of shorebirds at these locations.

On a quiet day with not many people to educate, there are many things for us Stewards to do. Some Stewards read their books, watch movies, listen to music/podcasts, color/paint, take walks, research, etc. I do all of the above! Since we have a love for these special shorebirds, most Stewards also birdwatch! It’s a must to bring your binoculars or scope to observe these beautiful birds. Sometimes, you observe other interesting animals, too!

Another activity to do in the down-time is to flip the spawning Atlantic Horseshoe crabs, Limulus polyphemus, back onto their legs so they can crawl back into the bay. When the tide rise, these crabs get overturned by the waves and have no way of returning back to their feet! Personally, this is my favorite activity to do. When you return after your “crab walk”, you get to see the tracks of their feet traveling back into the bay where they belong. Below on the left is a picture of flipped and rescued crabs: the one on the left is a male who decided to bury himself in the sand to preserve water until the tide comes back in, and the one on the right is a male who decided to make the trek back into the bay. When the tide comes in, the horseshoe crabs come up and begin spawning. Pictured below in the middle is an example of how crowded the beaches get with these creatures! On the right, is a photo of a tagged crab I found, and reported it to the US Fish and Wildlife Service so that they can collect data on the tagged crabs.
You can also get involved with helping these critters! “Return the Favor” is an organization dedicated to conducting beach walks to flip overturned horseshoe crabs on the NJ beaches of the Delaware Bay. You can join public walks that are held by walk leaders or sign up to be a volunteer and conduct your own walk (until July 15th, 2023 or next year). I am a volunteer and walk leader and it is one of my favorite things to do. Flipping horseshoe crabs is such a special event because that means you’re saving those crabs so they can continue to spawn and produce eggs for the shorebirds. With your help, you could help save hundreds of crabs just by flipping them over! Of course I had to capture this special moment of me flipping a crab (picture below)!
On these walks, you experience much more than just crabs. You get to see other wildlife that emerges during dusk or dawn. You can also go on the closed beaches to save the crabs that can’t be rescued during the day. During my walk, I got to see thousands of horseshoe crab eggs!

Hurricane Ida. Hurricane Irene. Superstorm Sandy. These weather events represent three of the four most devasting storms recorded in New Jersey history. Though data dates back 218 years, all 3 have occurred within the past 11, substantiating concerns over the effect of climate change on tropical cyclone severity. Therefore, taking measures to safeguard communities from devastating floodwaters is more important now than it ever has been. But who said helping people can’t, in turn, help wildlife?
Since 2003 Conserve Wildlife Foundation has been coordinating the Delaware Bay Shorebird Stewards. Shorebird Stewards are posted at the beaches with restricted access during the shorebird season. This is done so that the shorebirds can feed undisturbed on horseshoe crab eggs. The beach restrictions are from May 7th to June 7th. The Delaware Bay is an important stopover for these birds on their way north to their breeding grounds. Stewards educate the public about the need for the beach restrictions. Once most people learn about the connection between the horseshoe crabs and shorebirds, they are more than happy to accept the restrictions. This season there were thirty-one stewards on 10 beaches in Cape May and Cumberland Counties. They are dedicated and on the beaches despite the weather, bugs and sometimes lack of shorebirds. Stewards are on beaches through Monday, so stop by and say “hello”.
Thank you Shorebird Stewards

Conserve Wildlife Foundation has successfully completed the restoration of the Certified Wildlife Habitat behind the Trailside Nature and Science Center at Watchung Reservation. The project was initiated last fall with a major clean up of the overgrown and neglected garden. The cleanup included pulling weeds, digging up unwanted and overgrown plants, trimming shrubs and trees, clearing vines from trees, and raking and blowing leaves. As a result, sunlight was let into the garden so that new wildlife-friendly plants could be added. After the cleanup, new native shrubs were planted that attract bees, butterflies, hummingbirds, and other birds. A new deer fence was also installed to protect the plantings from deer browse.

May is wonderful time of year at the Delaware Bay. Horseshoe crabs are spawning and shorebirds stopping over on their migration to feed on the eggs. One of these shorebirds the red-knot, is a federally threatened species. Beaches along the Delaware Bay in New Jersey are extremely important stops in their migration. Many of these beaches have been restricted from May 7th to June 7th to allow the shorebirds to feed undisturbed. They need to gain enough weight to be able to fly non-stop to their breeding grounds in the artic.

People come from all over to view this natural phenomenon and the Delaware bay is a popular tourist destination. It’s important to have Shorebird stewards on these restricted beaches to educate the public about the crabs and shorebirds. Shorebird stewards support beach restrictions by being present at closed beaches during shorebird season to ensure that resting and foraging shorebirds are not disturbed. This job includes educating beach visitors as to why the beaches are closed and the importance of the beaches to horseshoe crabs and migrating shorebirds.
Stewards are needed short term in May at beaches along the Delaware Bay in Cape May County from the Villas north to Reed’s Beach and beaches in Cumberland.

Introducing Critter Chaos! The CWF team got together and selected 40 species that spend at least part of their lives in New Jersey to compete in a series of simulated battles to determine the most adapted (or luckiest) of the bunch. Call it a game of natural selection or simply of chance- contestants each represent one of four divisions; Shorebirds & Raptors, Mammals, Reptiles & Amphibians, and Grassland Birds & Invertebrates. We’ve given each contestant a rank within their division, based on their defense mechanisms, predatory techniques, camouflage, parenting style- anything that we felt would be relevant in fictional combat. The top competitor from each face-off will advance until we discover the worthy winner of the symbolic 2022 CWF Darwin Award.
If this is sounding a bit familiar, then yes- this competition is based on the NCAA basketball tournament “March Madness” and inspired by March Mammal Madness, a fun and educational alternative for those who are more (or equally) interested in springboks than sports. And if you’re most interested in spadefoots, then I’m pleased to tell you that the Eastern spadefoot toad is making an appearance as the #7 seed in our Reptiles & Amphibians division.

This fall CWF worked with the staff at the Trailside Nature and Science Center at Watchung Reservation in Union County, New Jersey to restore their Certified Wildlife Habitat. A Certified Wildlife Habitat must include sources of food, water, cover and places to raise young, and must be maintained using sustainable practices. Their garden had suffered from years of neglect and had become overgrown and choked out by weeds.
The first task was to tackle the major cleanup with the goals of opening the garden up to more sunlight, making room for new plantings, and giving the garden a fresh and clean appearance. CWF staff, interns and volunteers joined the Trailside Center’s staff and spent a day pulling weeds, digging up unwanted and overgrown plants, trimming shrubs and trees, clearing vines from trees, and raking and blowing leaves. Dead, dying, or damaged trees and shrubs were cut down. We left the healthy and beneficial trees, shrubs and herbaceous plants that will be the backbone of the refreshed garden. At the end of the day, the result of cleanup was remarkable. Sunlight can now reach the ground, and the garden became a clean slate to add new plantings that will benefit birds, bees, butterflies, and other wildlife.

The next step was to install a new deer fence around the garden. The Trailside Center lies within a wooded area and deer are drawn to the garden to munch on the shrubs and plants. In order to keep deer from destroying the garden, while allowing birds and other wildlife to utilize it, we installed a new eight-foot-high deer fence around the garden to replace one that had fallen down years ago. At the same time, we planted some new trees and shrubs in the garden that will be able to grow without the pressure of deer browse. We planted only native species that will attract birds, hummingbirds, bees, and butterflies to the garden.
In the spring, we will return to plant native herbaceous perennial plants that will also benefit birds, hummingbirds, bees, and butterflies. We will be sure to plant some host species for native butterflies, such as milkweed for monarchs. We plan to make a corner of the garden that caters specifically to hummingbirds. The garden is already home to a beautiful man-made creek flowing into a pond that draws birds and frogs. Several types of bird feeders, squirrel feeders and nest boxes are scattered throughout the garden as well. The restored garden will be unveiled this spring for visitors to observe through the viewing windows inside the Trailside Center.

We’ve all heard the expression “you can’t have your cake and eat it too”. For example, as a wildlife biologist, I can’t be promoted and still expect to spend most of my time in the field playing with turtles and salamanders- that would simply be too good to be true! The same phrase could probably be applicable to land; your property can’t simultaneously be profitable to you, the landowner, and beneficial to rare wildlife… right?
Well, in this case, I would have to disagree with the proverbial wisdom.
For many years, CWF biologists have worked with private landowners, other nonprofits, and the state and federal government to spread the word on programs that make wildlife conservation not only accessible, but economical. Why? Because >80% of New Jersey is privately owned. This gives residents a unique opportunity to be a part of the success story for every endangered, threatened, and at-risk species that, like us, call the garden state home. In the words of everyone’s favorite ‘90s superhero, Captain Planet, “The power is yours” – truly.
Prescribed grazing by livestock, like the cows pictured above or water buffalo below, can help improve hydrology in certain types of wetlands. If your property fits the criteria, NRCS can assist with the maintenance or installation of fencing as part of your restoration plan.Photo by Kristen Meistrell, NJ Audubon.
