Ongoing Grassland Restoration Efforts Improve Conditions for Grassland Nesting Birds

by Meaghan Lyon, Wildlife Biologist

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.

Protecting Seabeach Amaranth – New Jersey’s Endangered Beach Plant

by Todd Pover, Senior Wildlife Biologist

Seabeach Amaranth – Amaranthus pumilus

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.

Protecting Flood-Prone Communities Through Wetland Restoration

by Christine Healy

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?

Restored Garden is Ready for Wildlife at Watchung Reservation

by Meghan Kolk, Wildlife Biologist

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.

As the coordinator for CWF’s Amphibian Crossing Project, I think it’s safe to say I spend more time than the average person hoping for rain to pop up in springtime forecasts. April 22, however, is always an exception. What could be better than warm and sunny conditions to inspire folks to get outside and celebrate Earth Day by giving back to the planet that gives us, well, everything? Mother Nature certainly came through with the weather last week, handing us one of the most glorious days of the season thus far, while the Elizabeth Mayor Chris Bollwage, Union County Board of County Commissioners, Groundwork Elizabeth, and their partners offered a destination for all the aspiring wildlife warriors: Phil Rizzuto Park.

Habitat Enhancements for Rare Species at the Sea Girt National Guard Training Center

by Meaghan Lyon, Wildlife Biologist

Although the Sea Girt National Guard Training Center (NGTC) has just a small section of beach to manage, their efforts there with threatened and endangered species has been big. Conserve Wildlife Foundation of New Jersey has been a partner in these efforts, monitoring the piping plovers that nest on this beach during the breeding season and assisting in the planning of habitat enhancements. The protection area at the NGTC has been the nesting site of a piping plover pair for the past three breeding seasons and it is likely they will return again this spring, all while supporting the military and recreational missions of the New Jersey Army National Guard.

A Certified Wildlife Habitat Restoration in Progress

By Meghan Kolk, Wildlife Biologist

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.

New Jersey Piping Plover Breeding Population Rises Sharply in 2021

The 2021 New Jersey piping plover breeding season was a classic “good news, bad news” result. According to the annual report released by the state’s Endangered and Nongame Species Program earlier this month, the breeding population increased to 137 pairs in 2021, third highest since federal listing in 1986. That is an unprecedented 33% rise over the previous year and just short of the record high of 144 pairs in 2003. On the downside, the number of chicks fledged statewide was just 0.85 chicks per pair, the lowest since 2013 and about half of the 1.50 federal recovery goal. The low productivity was largely the result of a severe Memorial Day weekend nor’easter and persistent predator activity throughout the season.

Holgate, a unit of the Edwin B. Forsythe National Wildlife Refuge, hosted 46 pairs, the most in the state. This site, which is monitored and managed by CWF through a cooperative agreement with the Refuge, has seen an astounding increase in piping plover pairs in recent years, up about 2.5 times from the 18 pairs it had in 2018. CWF also monitors Little Beach, the adjacent Refuge-owned site, where another 13 pairs nested in 2021. Combined the two sites had 59 nesting pairs, a new record, by far, for the Refuge. Unfortunately, like the statewide results, productivity was very low this year at both Refuge sites, combined only 0.80 chicks fledged per pair, about half the rate just a year ago. The Memorial Day weekend nor’easter flooded those sites, wiping out most nests, and although most of the pairs nested again afterwards, many of those renests (or hatched chicks) were lost to predators, especially coyotes at Holgate.

CWF also oversaw piping plover breeding at the National Guard Training Center, which had just one pair in 2021, but that nest successfully hatched and fledged three chicks, helping boost the state average. Overall, CWF was responsible for monitoring 44% of the statewide population, giving it a significant role in helping guide conservation of this highly vulnerable state endangered (and federally threatened) species.

Although CWF does not conduct the daily on-the-ground monitoring and management of piping plovers at the Barnegat Inlet nesting site, it was a co-leader of the habitat restoration that was completed there two winters ago, and as such has had a big role in the nesting outcomes at the site. The number of pairs using the site has noticeably grown, up to five pairs in 2021 from just one pair when the project began. Productivity has also been consistently high at the restoration site and 2021 was no different with the pairs exceeding the federal recovery goal and statewide average with 1.6 chicks fledged per pair this year.

With the breeding results for 2021 now “in the books”, we are already looking forward to next year. The biggest question will be whether the state can sustain the progress towards recovery it made this year, especially given the big drop in productivity, which typically drives population. But for now, all we can do is wait until next spring to learn the answer to that question.

Own Your Land and Help Wildlife, Too: Exploring NRCS Partner Programs

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.
