The Bat Team setting up a mist-net in the Pine Barrens
Surveying for bats means staying up late and spending a lot of time in the dark. Our evenings begin a few hours before sunset, giving us just enough time to set up for the night. We start off by scouting locations to set up our mist-nets which we use to capture bats. These fine nets, ranging from 8 – 30 ft across and 16 ft high, are attached to tall poles stationed along corridors which bats often use to forage for food. With our nets ready to be deployed, we use the last of the daylight to set up our work station where we will process the bats we hopefully catch.

Since 2018, CWF has partnered with the USFWS New Jersey Field Office in completing summer mist netting surveys for bats in the Pinelands. The goal of these surveys is to capture the federally threatened Northern long-eared bat and track these bats to maternity roosts.

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.
Biologists Meaghan Lyon, Leah Wells, and Sherry Tirgrath each hold bats that were captured in nets and processed at camp before being released.
CWF’s team of biologists, along with several USFWS biologists from the New Jersey Field Office, specializing in bat surveying have been at it again for their fourth year of mist netting in the Pine Barrens. Mist netting surveys for bats starts at sundown and continues for five hours through to the early morning. The nets are set up across travel corridors through the woods with canopy cover and wetland foraging grounds nearby. As the bats head to and from their roosts and foraging grounds, they funnel through the corridors and into our nets. The bats are quickly and carefully extracted from the nets and then walked a short distance to our ‘camp’ where they are processed. Processing bats includes identifying bat species, sex, and reproductive status, as well as taking wing measurements.
Holgate, a unit of the Edwin B. Forsythe National Wildlife Refuge, is having another record year for piping plovers. A total of 49 pairs have nested at the site this year, up from 46 pairs in 2021, which was also a record, by far, from the previous high for the site. Since Superstorm Sandy devastated much of the New Jersey coast in October 2012, the number of piping plovers nesting at Holgate has increased fourfold.
Although most of CWF’s work focuses on protecting New Jersey’s imperiled wildlife, in a few cases our mission overlaps with at-risk plants, as well. One such case involves seabeach amaranth, a state and federally-listed plant that shares the beach with our endangered beach nesting birds. In the past, CWF’s effort to protect seabeach amaranth was more “behind the scenes” through the development of beach management plans with coastal communities that put measures in place to protect plants from municipal activities. Over the past several years, in partnership with and through funding by the U.S. Fish and Wildlife Service – New Jersey Field Office, CWF has now taken a more pro-active role in helping monitor and protect seabeach amaranth.
Starting in late May and all throughout June, CWF staff combs the state’s Atlantic coast beaches looking for amaranth plants that are just starting to germinate. Once found, the plants are protected with fence and signage, so they aren’t trampled by beach goers or driven over by vehicles conducting various beach maintenance activities, such as cleaning the beach with mechanical rakes. In the past they would have gone undetected and unprotected; few of the plants would have made it to the stage where they flower and produce seeds. Seabeach amaranth is an annual plant, its continued occurrence depends on seeds being produced and then dropped nearby or dispersed by wind or tides for next year’s “crop” of plants.
So far this season, mostly through the diligent fieldwork of CWF’s Biologist Sherry Tirgrath, we have located and protected 811 plants at 19 sites leading into the busy July 4 th holiday. The highest concentrations of plants are on beaches in southern Monmouth and northern Ocean counties. Since seabeach amaranth was rediscovered in New Jersey in 2000 – it had been absent since 1913 – Monmouth County, in particular Sandy Hook, a unit of Gateway National Recreation Area, has harbored most of the state’s seabeach amaranth population. However, over the past few years, increasingly more plants have been found on Ocean County beaches. In addition to increasing the overall population of plants, this wider distribution is one of the goals of the CWF/USFWs initiative.
With the early season work completed, CWF will now move onto other phases of the project. That includes repeat surveys for later germinating plants, ongoing maintenance of the fence we erected, and coordinating with the state’s beach nesting bird staff as they remove their fence once breeding season ends so it can be checked for plants. Those sites often have large numbers of plants as that habitat has been protected for birds – and as a result plants too – since late March or April. Finally, an annual statewide survey of seabeach amaranth occurs in late July and August and CWF will be “on call” to fence plants that are found by those survey crews. Plants can persist until late November in years with mild fall weather and low-flooding, in those cases our fence could remain up until then, so our work for the season has really just begun.
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?
The Kindergarteners at Ridge Street School in Newark, New Jersey, have been utilizing Conserve Wildlife Foundation’s Soaring with STEAM curriculum in their classrooms. From snakes and turtles to whales and woodpeckers, the students are learning all about the endangered species that call New Jersey home as well as the unique habitats in which they reside. Each lesson includes hands-on activities to drive home what they have learned, with all materials provided by CWF. Students have enjoyed using their creativity to make each lesson activity their own! They have been given the opportunity to build snake dens, design a habitat for their favorite animals, and practice breathing like humpback whales. Kindergarten teacher Aracelys Muniz says students look forward to these lessons each week and call their CWF lesson days the “Best day ever!”. By providing positive experiences for students at such a young age in the realm of wildlife sciences, we hope to engage with and inspire the next generation of environmental stewards. Our goal is for students to remember our lessons beyond the classroom, becoming excited to continue learning on their own and sharing their knowledge with their friends, families, and communities. CWF thanks PSEG Foundation, Victoria Foundation, The Merrill G. and Emita E. Hastings Foundation, David A. and Carol B. Lackland Family Foundation, and the Zoological Society of New Jersey for their generous support for our work with Newark Public Schools.

It’s officially chick season for the beach-nesting birds of New Jersey, and some of the first, fuzzy babies of the year were hatched at National Guard Training Center in Sea Girt. Piping plovers, Joey and Hamlet, laid their third nest together after first nesting at NGTC in 2019. The pair both had different partners that year, but got together in 2020 and fledged three chicks together for two years in a row. This year, the pair had the first confirmed nest in the state and diligently incubated their eggs during the entire month of May. The nest was anticipated to hatch over Memorial Day Weekend.
Just a couple days before the chicks made their appearance, tragedy struck. Hamlet was not seen for a couple days, and fear started growing that something had happened to her or she abandoned the nest, which would be very unlikely for such a devoted and successful veteran mother. When the chicks finally hatched from their eggs on May 29th and only Joey was seen tending to them, some investigating was done into Hamlet’s disappearance. Her body was found at the edge of NGTC property, likely predated by an owl or other bird of prey, as evidenced by the condition of her body. As tragic and sad as her death was, it’s a wonder that her body was found at all. In many cases, there’s no closure for piping plover disappearances. Joey was left to raise his chicks as a single father, receiving praise and encouragement from everyone following his story.
The chicks have reached the 10-day mark as of June 8th, and appear healthy and strong. Only two have made it this far, but Joey is doing an excellent job on his own protecting them from threats and keeping them in line. We’re keeping our fingers crossed that both chicks make it to fledging, and Joey can keep up his excellent fatherhood record. It’s unknown if Joey will seek a new mate next year or retire from parenthood, but for now, we are saddened by the end of the era of Joey and Hamlet.
Monitoring of beach-nesting birds takes time and commitment from our team of biologists and seasonal technicians. The largest piping plover breeding population in New Jersey resides at our Holgate site, where pairs, nests and hatched chicks are observed and tracked nearly every day during the nesting season. Nests north of that site are sparser and face many threats from human disturbance and high predator presence. While the coastal piping plover population is still struggling, CWF continues to fight to protect our state’s rare species and educate the public about the importance of respecting wildlife.
Earlier this week CWF and USFWS biologists joined forces to start off the season with a grassland bird survey in Burlington County, New Jersey. The vast grassland habitat, doubling as an airfield, is home to the state endangered upland sandpiper, state threatened grasshopper sparrow, savannah sparrow, and bobolink, as well as the eastern meadowlark, a species of concern. These bird species, among many others, can all be found nesting at this site in the clumps of grass during the months of May, June, and July. Many of the management practices at the airfield, like consistent mowing, help maintain this grassland habitat and keep it an early successional state for grassland birds to nest in year after year.
For the survey, biologist met on site just before sunrise with binoculars hanging from their necks and clipboards with data sheets in hand. Male birds were already perching on tall blades of grass and singing to attract mates and defend territory as we dispersed to our survey points. At each point it was our job to distinguish what bird song and calls we were hearing and record any focal species activity onto our data sheets.
Between the three surveyors and 25 survey points, all of the target species were identified as well as hundreds of red-winged black birds, two great egrets, and a few mallard ducks. Of particular note, one upland sandpiper pair was sighted in its usual nesting area.
Three more surveys will follow between now and the end of the grassland bird nesting season. Follow along for updates throughout the season!
