New Jersey: Biologists Utilizing New Tools to Mitigate the Impact of Climate Change

Refuge biologists head to the field at Edwin B. Forsythe National Wildlife Refuge to study ways to manage marsh habitats in the face of climate change. The refuge hosted a workshop in 2010 so biologists from Northeastern national wildlife refuges could learn how to manage salt marshes to adapt to climate change. Photo: Bill Butcher, USFWS.

Edwin. B. Forsythe National Wildlife Refuge in Oceanville, New Jersey, is among the first wildlife refuges in the country to complete the Climate Change Vulnerability Assessment for Shorebird Habitat, which not only measures how vulnerable a habitat is to the effects of climate change, but also enables managers to consider how to sustain such habitats.  The assessment looks at a range of stressors, including sea level rise, increased frequency and intensity of storms, and changes in precipitation and temperature.  

The assessment shows that climate change threats at Forsythe Refuge will be magnified over time, with much higher risk in 2100 as compared to 2025.  Potential risks include sea level rise inundating habitats, storms destroying beaches and dunes, erosion of tidal creek banks, ocean acidification affecting invertebrates that birds feed on, and heavy rainfall causing greater runoff of pollutants into tidal flats.

Refuge staff is using the assessment results to develop a habitat management plan.

Forsythe Refuge mainly consists of tidal salt meadow and marsh. Tens of thousands of migrating shorebirds, wading birds, ducks and geese use the refuge in the spring and fall to rest and eat the rich food resources. Other birds remain through the summer to nest and raise their young. 

Nesting habitats for American oystercatcher and piping plover, as well as stopover habitat for red knot during its lengthy fall migration are particularly vulnerable.
