Western Hemisphere Shorebird Reserve Network

Funding: Arctic Shorebird Demographics Network

Existing shorebird monitoring efforts are aimed at providing population size and trend estimates, along with environmental data to help interpret the estimates. However, current programs cannot provide information to determine which life history stage(s) of shorebirds is (are) likely to be limiting overall population growth in declining species. Is it reproductive success? What about the rate of survival of the juveniles, or of the adults? Or perhaps it is some combination of these factors?

This summer, the ambitious and long-sought dream of being able to answer these important conservation questions became a reality with the launch of the Arctic Shorebird Demographics Network (ASDN). Under the leadership of Dr. Stephen Brown of Manomet Center for Conservation Sciences, Dr. Rick Lanctot of the U.S. Fish and Wildlife Service (USFWS) in Alaska, and Dr. Brett Sandercock of Kansas State University, the ASDN currently connects the work of shorebird biologists at nine field stations and sites across the vast Arctic breeding grounds of North America, from western Alaska to eastern Canada. Scientists hope to further strengthen the network in 2011 with a total of 11 locations.

Field stations and sites include:

Understanding the potential factors limiting the populations of so many declining species at this enormous scale is critical to targeting conservation efforts at the right times and places. Dr. Brown underscores the enormity of this project in saying, “we are starting the most ambitious effort ever undertaken to measure survival and reproductive rates of shorebirds, which will allow us to determine when and where their populations are limited.” The ASDN focuses on migratory shorebirds that breed in the Arctic but migrate and winter throughout the Western Hemisphere.  Such migratory species directly experience and are affected by environmental changes occurring throughout their annual range, thereby serving as indicators of that change to scientists. 

An initiative of this scale would not be possible without the collaborative spirit of many partner institutions. A special thank-you to the following partners for taking the lead on supporting one of the existing or potential research sites: Yukon Delta National Wildlife Refuge, Simon Fraser University, Kansas State University, U.S. Fish and Wildlife Service - Alaska Regional Office, the Wildlife Conservation Society, Environment Canada, and Trent University. 

Major support for the coordination of the ASDN comes from Manomet’s Research and Development Fund, along with generous funding from the National Fish and Wildlife Foundation through its Alaska Fish and Wildlife Fund, the USFWS through the Cooperative Ecosystem Studies Unit and the Arctic Landscape Conservation Cooperative, the Alaska Department of Fish and Game, and the National Science Foundation’s Office of Polar Programs.
