Over the past five years, long term efforts have been ongoing to complete a large-scale grassland restoration at the McGuire Airfield. So far, roughly 500 acres have been treated and seeded to encourage the growth of native warm season grasses with another 100 acres to be completed by next spring. The planting of species like little bluestem, sideoats grama, and blue grama has helped to create grassland bird nesting habitat and conserve existing habitat, while accommodating necessary airfield procedures and safety.
Keeping the vegetation on the airfield short is important to ensure airport safety and to achieve that goal, the fields must be mowed. When the vegetation reaches 12-14 inches, the area is mowed back down to 7 inches. The vegetation before the start of the restoration project was a mix of native and non-native woody, forb, and grass species, with some plants growing at a faster rate than others. The quicker these plants grow, the more frequent mowing must occur. It’s for this reason why native warm season grasses were planted, which have a slower growth rate and tend not to grow more than 12-14 inches. By planting these species and reducing mowing frequency, the grassland birds have less disturbance and human impacts on their nesting season.
This work is done in cooperation with the USFWS New Jersey Field Office, and grassland bird surveys are completed throughout the summer to monitor success. Stay tuned to learn more about our grassland bird results for the 2022 breeding season.
Vegetation must be mowed when grasses exceed 12 inches.
It’s always a good day when we get a resighting of a NJ banded eagle, especially if it was one that had a transmitter attached. On November 1st, 2022 “Oran” was resighted in Stone Harbor, Cape May County, NJ by John Kauterman. This is about 22 miles from where he had fledged along the Delaware Bay in Cumberland County in 2015.

On May 18th, 2015 a remote eagle nest on the Delaware Bay was visited by biologists with the NJ Bald Eagle Project, from both the NJ ENSP & CWF. There were two eight week old chicks in the nest both and we banded both. The male, banded NJ Green band E-17, was outfitted with a transmitter and he was named “Oran”.
It’s official. The Northern long-eared bat is listed as an endangered species under the U.S. Fish and Wildlife Service’s (USFWS) Endangered Species Act. Earlier this year, the USFWS announced the proposed uplisting due to severe population declines. This uplisting would help to protect and recover this imperiled species and the ecosystems upon which they depend on.
A Northern long-eared bat is held in a gloved hand- these bats are less that 4 inches long with a wingspan of 9-10 inches.
Through the Endangered Species Act, species may be listed as either endangered or threatened. The term “Threatened” means a species is likely to become endangered within the foreseeable future. The term “Endangered” means a species is in danger of extinction throughout all or a significant portion of its range.
An osprey nest with hatchlings on May 16, 2022. One of many nests that eventually failed to produce young this year.
Whenever we look at how ospreys are faring, weather is always taken into account. When we summarize and report on the results of our summer osprey nesting surveys, we also look at the local climate. Being situated along the Atlantic coast, our weather is influenced by the ocean. As aerial predators of fish, ospreys are reliant on favorable water conditions to forage.
Preliminary results of the 2022 New Jersey Osprey Project Census show that the osprey population was not as productive this year as they have been over the past ~20 years. This was largely due to a low pressure system (nor’easter) that stalled off the coast in early May — when the majority of pairs were incubating eggs. The strong onshore winds caused moderate coastal flooding, windy conditions, increased wave action and water turbidity, which made it more difficult for ospreys to find and catch prey in coastal waters. Males do 100% of the foraging from the onset of egg laying until young begin to fledge, so when they are unable to provide food, females must abandon their nests and eggs to forage for themselves. The nor’easter in May appears to have affected the outcome of many coastal nests and in some cases, complete colonies. Of course there are many other causes for nest failure but this year weather played a major role.
Once leaves fall to the ground, leave them be! Deciding not to rake, blow, and dispose of your leaves not only benefits native wildlife but provides nourishment to your garden and lawn.

I am a volunteer eagle nest monitor for New Jersey’s Bald Eagle Project. A new nest was discovered in central New Jersey this year by birder Chris Brown. Larissa Smith, the volunteer coordinator for the Bald Eagle Project and Conserve Wildlife Foundation asked me to monitor this nest. I did not know at the beginning of nesting season, what an interesting story would unfold! In mid-April, by watching the behavior of the adult eagles, I could see that eggs had hatched and that the adults were feeding eaglets that were still too small to see. At the beginning of May I caught glimpses of the head of one eaglet peeking up over the top of the nest rails. Too cute! By the end of May, I could see the head of a second chick in the nest. But this chick looked very different! I soon discovered this chick looked different because it was not a Bald Eagle at all! It was a red-tailed hawk chick in the eagles’ nest! I could not believe what I was seeing! I took lots of photos to document this situation, a first for New Jersey! I consulted with two respected birders in the state, Chris Brown, who is a county eBird reviewer and Tim Brown, to help verify and document my observations for CWF and the NJ DEP/ENSP. We observed the adult eagles feeding both the red-tailed hawk chick and the bald eagle chick. It was one big happy family, with both chicks getting along with each other and with the adults quite well.

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.
New Jersey Eagle Project nest monitors Cathy and Jeff White have been volunteering with the program since 2009. The 2022 eagle nesting season was officially their last as they will be “retiring.” When they started with the bald eagle project, they had two eagle nests that they monitored in Southern New Jersey. As of 2022 they were monitoring 25 eagle nests. That is a lot of nests to keep straight! During their 14 years of observing nesting behavior to determine egg laying, hatching, and fledging, a total of 244 eagle chicks fledged from their nests. The Whites have witnessed the eagle population grow over the years and have played a large role in the success of the eagles, including many rescues of both chicks and adults. Their dedication to the eagles through both the good and bad outcomes, is commendable and they are irreplaceable.
They have done so much for the eagle project and will be greatly missed. Thank you!

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.
Hello! I would like to introduce myself as a new member of the Conserve Wildlife Foundation of New Jersey team. My name is Rachel McGovern, and I am joining CWF as the Education Director.
I am a lifelong NJ resident and have always been passionate about environmental issues in the state. After completing my undergraduate degree in Human Ecology at Rutgers University, I spent a year in the Americorps New Jersey Watershed Ambassador Program (NJWAP) where I first taught environmental education lessons. Since then, I have had wonderful experiences teaching at nature-based organizations across the state.
Most recently, I was the Program Director at Flat Rock Brook Nature Center in Englewood, NJ. This center is located on a 150-acre forested preserve surrounded by dense development just minutes from the George Washington Bridge. At Flat Rock Brook, I led the education team in developing and delivering school programming, community events, and summer camp. I was also fortunate to take on the care of five non-releasable raptors—a job that deepened my admiration for all raptors in NJ (particularly falcons).
