Reflecting on a Year of Growth for Seabeach Amaranth

Wednesday, August 16th, 2023

by Sherry Tirgrath, Wildlife Biologist

The population of seabeach amaranth (Amaranthus pumilus) in New Jersey has continued its upward trend for the 2023 season, marking another successful year of protecting the rare and vulnerable plant. Since 2019, CWF has partnered with the U.S. Fish and Wildlife Service – NJ Field Office (USFWS-NJFO) in monitoring and managing the state’s population of seabeach amaranth (SBA), a federally-threatened and state-endangered coastal plant. The number of SBA in the state fluctuates each year but suffered tremendously in the past due to coastal erosion, habitat loss, and disturbances from recreational use and municipal beach management. For 87 years, from 1913 until 2000, the species wasn’t seen in New Jersey. Plants have started rebounding on certain beaches in recent years, with numbers now in the thousands.

It’s a Wrap! First Season of Delaware Bay American Oystercatcher Monitoring is a Success

Tuesday, August 15th, 2023

by Emmy Casper, Wildlife Biologist

This past winter, CWF announced a new project designed to study and monitor the population of American oystercatchers breeding along the New Jersey side of the Delaware Bay. In addition to locating nesting pairs and tracking their success, our goal is to better understand how oystercatchers utilize the bayshore habitats and what factors threaten their productivity. The data we gather with our partners at The Wetlands Institute and U.S. Fish and Wildlife Service will be used to inform future management decisions. We spent the past few months working hard to conduct the project’s first season of monitoring, and we are happy to say that we have made significant progress in beginning to unravel the mysteries surrounding this understudied population.

Since so little is known about this subpopulation of oystercatchers, we had a lot of ground to cover in our first season of fieldwork. First, we had to locate any breeding oystercatcher pairs across 35 sites spanning approximately 45 miles of bayshore from Cape May Point to Sea Breeze. Luckily, we had a head-start based on a preliminary census survey from 2021 that documented some already existing pairs as well as some sites with potentially suitable nesting habitat. We were also fortunate to have a dedicated seasonal technician assisting with the heavy workload. That said, figuring out how to access many of these sites was definitely a learning curve. We quickly discovered that many beaches were only reachable by boat or kayak and only during a narrow window of tide and wind conditions. Other sites were walkable, but only at peak low tides, which meant our surveys couldn’t take too long without risking becoming stranded by the rising tide.

In the News: WHYY Article Highlights New Delaware Bay Marsh Restoration Project

Thursday, March 9th, 2023

by Emmy Casper, Wildlife Biologist

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.

Announcing New NFWF Funded Project to Study and Monitor American Oystercatchers along the Delaware Bay

Wednesday, February 15th, 2023

by Emmy Casper, Wildlife Biologist

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.

Giving the Federally Endangered Bog Turtle a Fighting Chance in New Jersey

Coalition of Agencies Working Together to Enhance Turtle Habitat in Sussex County

Through federal partnerships and incentive programs, the federally endangered bog turtle can have a fighting chance in New Jersey! The U.S. Department of Agriculture’s Natural Resource Conservation Service (NRCS) and the U.S. Fish and Wildlife Service (USFWS), in partnership with Conserve Wildlife Foundation, New Jersey Audubon Society, and Wallkill River Watershed Management Group, are currently working to restore a once natural wetland on private property in Sussex County. The program is possible through the Agricultural Conservation Easement Program, Wetlands Reserve Easement (WRE). WRE is a voluntary program that provides an opportunity for landowners to receive financial assistance in exchange for permanently protecting retired agricultural land. In their first year, NRCS and USFWS helped to restore and protect 52 acres of bog turtle habitat in New Jersey!

 

The goal of this project is to restore hydrology, enhance bog turtle habitat, control invasive species, and stabilize the stream bank. Through the partnerships we have already planted riparian buffers along the river and plan to conduct invasive species removal and create shallow water pools for wildlife such as amphibians.

The site contains active bog turtle habitat that has been degraded over time through grazing and other human induced impacts. Bog turtles are found throughout the state, but Sussex County is a hot spot because of its prime wetlands habitat. At the bog turtle site, cattle will be actively managed to graze the area for specific periods of time throughout the year. This will reduce invasive species and create mucky soils preferred by the bog turtle.

New Jersey Audubon Society was also able to supply a native sedge plant to enhance the wetland. Last week, a youth corps group from Phillipsburg, New Jersey met on site to help plant green bulrush. The bulrush will aid to improve water quality, as it will take up phosphorous and other nutrients moving into the water column. It will also aid to reduce erosion and provide food and cover for ducks, and other water birds. So far, 5,050 plugs of green bulrush have been planted!

CWF has also partnered on other Sussex County bog turtle restoration projects with the New Jersey Division of Fish and Wildlife’s Endangered and Nongame Species Program, National Fish and Wildlife Foundation, USFWS, and the New Jersey Corporate Wetlands Restoration Program.
