CWFNJ Returns to Blue Acres Tremley Point for Fall Planting

by Sherry Tirgrath, Wildlife Biologist

Restoring floodplains and protecting urban communities may not sound like a typical workday for the biologists of Conserve Wildlife Foundation of NJ (CWFNJ). However, multiple staff and board members of CWFNJ were present at the annual Blue Acres Floodplain Restoration Fall Planting and Clean-up Day on October 27th, clearing weeds, trash and planting new trees and shrubs at the Tremley Point restoration site in Linden. Blue Acres, a program created by the New Jersey Department of Environmental Protection, helps residents in low-lying areas that are subject to repeated flooding by buying out their properties and aiding in homeowner relocation. The acquired properties eventually become buffer zones, such as floodplains, that protect surrounding communities from the impact of storms and rising sea levels by acting as natural floodwater storage. The land purchased through the Blue Acres program may also be restored into functional wetlands, habitat for wildlife and open green space for the community to enjoy. Blue Acres not only provides disaster relief for residents whose homes have been destroyed or damaged by flooding and surges caused by large storms, but also contributes to the NJ Climate Change Resilience Strategy by proactively creating wetlands and floodplains to lessen the severity of future flood events.

It is Bat Week!

by Meaghan Lyon, Wildlife Biologist

Internationally celebrated, Bat Week runs from October 24th through October 31st. This week we celebrate bats to raise awareness for these nocturnal creatures that are often left in the dark. In New Jersey, we have two federally listed bat species, the Indiana bat and the Northern long-eared bat. Several more bats are being uplisted to the threatened and endangered list. Threats primarily include habitat loss and a fungal disease called white-nose syndrome.

2023 JB McGuire Grassland Bird Survey

by Meaghan Lyon, Wildlife Biologist

Each year since 2017, CWF has been teaming up with partners from the USFWS New Jersey Field Office to survey the JB McGuire Airfield for grassland birds during the breeding season.  Part of a long-term monitoring project, the airfield has been undergoing habitat restoration to maintain native warm season grassland habitat. The habitat restoration efforts are nearly 70% complete with roughly 700 acres seeded since 2017 and another 100 acres to be completed the following year.

Six of the ground-nesting bird species documented at the airfield are State-listed as either endangered, threatened, or of special concern.  The eastern meadowlark (Sternella magna), a member of the blackbird family, is a State Species of Concern.  It prefers a minimum of ten to twenty acres of unfragmented dense grasses of medium height for nesting.  The State-threatened grasshopper sparrow (Ammodramus savannarum) favors patches over 100 acres containing short- to medium-height bunch grasses interspersed with patches of bare ground, a shallow litter layer and scattered forbs. The savannah sparrow (Passerculus sandwichensis), also State-threatened, requires a mix of short and tall grasses, a thick litter layer, dense ground vegetation, and scattered forbs.  Another member of the blackbird family is the State-threatened bobolink (Dolichonyx oryzivorus).  Bobolinks prefer to place their nests in areas of greatest vegetative height and density and could potentially nest in patches as small as five to ten acres.  The State-threatened horned lark (Erimophila alpestrias) nests in areas of barren ground with short and sparse cover and are quick to abandon sites as vegetation grows thicker.

Barn Owls in Monmouth County

by: Larissa Smith, CWF Senior Biologist

Barn Owls (Tyto alba) are one of the most widespread avian species in the world. Despite this impressive distribution, their numbers have been decreasing in parts of their range, and New Jersey is no exception. The barn owl population in New Jersey is in decline due to habitat loss associated with urban sprawl and development of former agricultural lands. Little is known about the Barn Owl population in central New Jersey. Through a grant from the Monmouth Audubon Society, Conserve Wildlife Foundation of New Jersey is partnering with Monmouth County Park System and the New Jersey State Park to construct, install and monitor three barn owl boxes. By providing suitable nest site opportunities we can potentially boost the barn owl population locally within Monmouth County as well as regionally as fledglings disperse to find their own nesting areas.

The first step of the project has been completed. CWF biologist Christine Healy and her Father Jim Healy have constructed three nest boxes that are ready for installation.


Would you like to learn more about the elusive Barn Owl, support the CWF Barn Owl Project and have a fun family night? Join us at Howls for Owls, at the Screamin’ Hill Brewing.

We Hope to see you there. This outdoor event will be cancelled for bad weather, so please stay updated on our website.

A New Science Partnership Grows on Long Beach Island

By Todd Pover, Senior Wildlife Biologist

CWF had a busy summer at the Long Beach Island Foundation of the Arts and Sciences (LBIF), having launched a new partnership this year to help strengthen their science programming through a grant from the Osprey Foundation. A number of offerings targeting both adults and kids, highlighted by three week-long science camps for ages 7-9 and 10-12, were developed and led by CWF’s staff. The LBIF facility, with its close proximity to both the ocean and bay, is an ideal location to feature New Jersey’s coastal species and their unique conservation challenges.

Gardening for Terrapins

by Ben Wurst / Senior Wildlife Biologist

Work on this project is done under NJDEP Fish & Wildlife Scientific Collecting Permit SC2023048

When we founded the Great Bay Terrapin Project, our goal was to reduce roadkills of adult female northern diamondback terrapins. This was largely due to personal observations of multiple roadkills during the summer months along roads in Little Egg Harbor Township and past research which accounted for a large number of adults DOR (dead on road). Since 2010, we’ve been able to cut the historic roadkill rate in half, all thanks to our devoted volunteers who patrol area roads and raise awareness for them! This allows adults to grow larger and live longer lives, which helps to ensure their long term survival.

The Complicated History of Our Marshes and an Update on Restoration Progress

by Caroline Abramowitz, CWF Biological Technician

When looking at the expansive mudflats along the marshes of the Delaware Bay, it is hard to imagine that the area was once densely vegetated and home to a variety of bird species. This spring, CWF began work on a new marsh restoration project funded by the National Fish and Wildlife Foundation and led by Ducks Unlimited and the U.S. Fish and Wildlife Service (USFWS). CWF was contracted to assist with biological monitoring at sites targeted for marsh restoration along New Jersey’s side of the Delaware Bay. Restoration efforts for our sites are being directed toward mudflats that exist due to significant physical alterations made to the marsh in the past. The story of how these mudflats came to be lies in the area’s history and roots in salt hay farming.

As early as 1675, settlers arriving on the Delaware Bay built dikes in salt marshes to protect land from saltwater inflow and create an environment more conducive to salt hay farming and development. One of the most important types of salt hay harvested along the Delaware Bay was Spartina patens, a crop that was widely used as bedding and feed for livestock due to its high nutritional value. By the mid-1800s, at least 14,000 acres of marsh were impounded in Salem County alone with comparable areas altered in both Cumberland and Cape May counties (Cook, 1870). Impoundments restricted tidal flow within the marsh, which stopped the natural process of marsh accretion in which sediment is consistently added to the marsh to increase its elevation. Additionally, drier conditions exposed marsh soil to too much air, resulting in the breakdown of soil and further loss of elevation.

Collaborative Projects Gather Data About Bats in the Garden State

by Leah Wells, Assistant Wildlife Biologist

Conserve Wildlife Foundation of New Jersey (CWF) works hard every summer to protect New Jersey’s bats by employing continuous research, education and outreach endeavors. Our Summer Bat Count project and Mobile Acoustic Surveys, both in collaboration with the State’s Endangered and Nongame Species Program (ENSP), are essential components of these efforts, enabling us to gather and document crucial information about bat populations within the state.

Since 2003, the Summer Bat Count project has relied upon the commitment of dedicated volunteers. Equipped with only a fresh set of eyes, these volunteers tally bat populations at known summer roost sites, whether it be a bat house, attic, bridge or church. The project’s primary goal is to gain a deeper insight into the distribution of bats across the state, their preferred roosting conditions and the fluctuations in population over time. While the outcomes of this year’s survey are still pending, emergence surveys during the 2022 maternity season revealed a noteworthy increase in bats for a particular roost in Warren County. This roost has been consistently monitored, with data dating back before the introduction of White-nose Syndrome.

JB MDL Military Conservation Partnership Award & CWF Projects

by Meaghan Lyon, Wildlife Biologist

Earlier this year, the U.S. Fish and Wildlife Service (USFWS) awarded Joint Base McGuire, Fort Dix, and Lakehurst (JB MDL) with the Military Conservation Partnership Award for outstanding efforts to protect both State and Federally listed threatened and endangered species. The award recognizes significant natural resource management achievements by military installations, particularly the conservation of important wildlife and their habitats through cooperative work with USFWS and other partners. CWF has been a major partner on many projects at JB MDL spanning from grassland habitat restoration and monitoring, myotis bat surveys and tracking, and a full mammal inventory.

Over the past six years, long term efforts have been ongoing to expand and protect grassland habitat at the McGuire Airfield. So far, roughly 600 acres have been restored to 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. Grassland bird surveys are conducted each summer to monitor success of species like upland sandpiper and bobolink.
