Over the winter, biologists from CWF, Ducks Unlimited, USFWS, and Partnership for the Delaware Estuary visited sites like this marsh in Dix Wildlife Management Area to assess their restoration potential and strategize monitoring plans.
This spring, CWF will begin fieldwork for a new marsh restoration project along the Delaware Bay. The ambitious project, funded by the National Fish and Wildlife Foundation and co-led by Ducks Unlimited and the U.S. Fish and Wildlife Service, aims to implement cost effective and low-tech marsh restoration techniques in New Jersey and Delaware salt marshes. Restoration plans will be designed to create, protect, and/or enhance habitat for multiple marsh-dependent species including black rails and saltmarsh sparrows. As a project partner, CWF will provide two seasons of biological monitoring assistance at the New Jersey sites. This week, WHYY published an article about the project, featuring representatives from CWF and other project partners.

CWF is excited to announce a new project funded by the National Fish and Wildlife Foundation’s Delaware Watershed Conservation Fund designed to develop and execute management strategies for American oystercatchers along the Delaware Bay. Breeding populations of American oystercatchers (State Species of Special Concern) have been well studied and monitored along New Jersey’s Atlantic Coast since 2003, but very little is known about the oystercatchers that nest on the sandy beaches along the Delaware Bay. In 2021, CWF conducted a near bay-wide window census survey to establish a baseline estimate of the Bayshore population. Thirteen oystercatcher pairs were documented across approximately 35 sites from Cape May Point to Sea Breeze, prompting a need for further research and management. This new project seeks to shed light on this understudied population and add to our scientific understanding of their management needs.

Conserve Wildlife Foundation’s research with scientist Dr. Larry Niles was highlighted in today’s New York Times feature detailing the 80 percent decline in red knots in New Jersey’s Delaware Bay this spring.

A sudden drop in the number of red knots visiting the beaches of Delaware Bay during migration this spring has renewed concern among scientists about the survival of the threatened shore bird’s Atlantic Coast population.
According to biologists, the number of knots that stayed to feed at the bay in May declined by about 80 percent from the same time last year. The Delaware Bay is one of the world’s most important sites for shorebird migration.

A migratory stopover for arctic nesting shorebirds must provide each bird the energy necessary to get to the next stopover or to the ultimate destination, the wintering or breeding area. Delaware Bay stands out among these shorebird refueling stops because it delivers fuel in the form of horseshoe crab eggs giving birds options. Our telemetry has shown that Red knots, the species we best understand, may leave Delaware Bay and go directly to their Arctic breeding areas, or stopover on Hudson Bay. The choice of going straight to the breeding area or stop at another stopover may be critical to understanding the ecological dramas now underway on Delaware Bay.
When asked to describe the ecological conditions of any one year of our 23 years of work on Delaware Bay, Humphrey Sitters, one of the first biologists to understand the value of Delaware Bay to shorebirds would respond “every year is unprecedented”. And so it seemed until this year.
