Western Hemisphere Shorebird Reserve Network

Western Hemisphere Shorebird Reserve Network
Name	Western Hemisphere Shorebird Reserve Network
Location	Americas, Caribbean
Established	1985
Governing body	Manomet (U.S. Secretariat)

Western Hemisphere Shorebird Reserve Network. It is an international conservation strategy dedicated to protecting key habitats for shorebird populations across the Americas. Established in 1985 through a partnership between Manomet and the International Wader Study Group, the network identifies and designates critical sites used during bird migration and breeding. This initiative connects a chain of essential wetlands, beaches, and grasslands to support species from the Arctic to Tierra del Fuego.

Overview

The network was formally launched following a 1984 conference in Edmonton, organized by Brian Harrington of Manomet and Guy Morrison of the Canadian Wildlife Service. Its creation was driven by alarming declines in species like the red knot and semipalmated sandpiper, documented by research at locations such as Delaware Bay. The strategy is modeled on the Ramsar Convention but focuses specifically on the habitat needs of migratory shorebirds. The U.S. Fish and Wildlife Service and Environment and Climate Change Canada were among early governmental supporters of the concept.

Designation criteria

Sites qualify for inclusion based on rigorous biological thresholds related to shorebird abundance. A location can be designated as Hemispheric, International, or Regional based on the total numbers of birds it supports annually. Hemispheric sites must regularly support at least 500,000 shorebirds or 30% of a species' flyway population, such as those documented at the Bay of Fundy. International sites support 100,000 birds or 10% of a flyway population, while Regional sites support 20,000 birds or 1% of a population. These criteria are applied across diverse ecosystems from tundra to mangrove forests.

Network sites

The network encompasses over 100 key sites across more than 15 countries. Notable Hemispheric sites include Cheyenne Bottoms in Kansas, Copper River Delta in Alaska, and Lagoa do Peixe National Park in Brazil. Major International sites range from the Paracas National Reserve in Peru to the Fraser River Delta in British Columbia. Regional sites include critical stopovers like the Altamaha River estuary in Georgia. The network spans the entire Pacific Flyway and Atlantic Flyway, creating a connected chain of essential habitats.

Conservation role

The primary role is to safeguard sites from threats like coastal development, pollution, and climate change. Designation often elevates a site's profile, aiding local conservation groups in advocacy and securing protective designations. For example, the network has supported conservation actions at San Francisco Bay and the Mississippi River Delta. It plays a crucial role in implementing the United Nations Sustainable Development Goals related to life on land and below water by preserving ecosystem services provided by healthy wetlands.

Partnerships and management

Management is collaborative, involving a wide array of partners. The U.S. Secretariat is housed at Manomet, while Wetlands International often coordinates efforts in Latin America. Key partners include national agencies like Parks Canada and CONANP in Mexico, as well as non-governmental organizations such as Ducks Unlimited and the National Audubon Society. Local landowners, indigenous communities, and municipal governments are integral to on-the-ground stewardship at sites like Quill Lakes in Saskatchewan.

Research and monitoring

The network is underpinned by robust science, including the Program for Regional and International Shorebird Monitoring (PRISM). Long-term banding programs, like those led by the Patuxent Wildlife Research Center, and aerial surveys track population trends. Research on species such as the Hudsonian godwit and western sandpiper informs conservation priorities. Technological advances, including satellite telemetry and geolocator studies conducted by the Max Planck Institute for Ornithology, have revolutionized understanding of migratory connectivity between sites like Mono Lake and Chiloé Island.
