Summary:

Worldwide Species Action Plans

Marbled Godwit action planThe Marbled Godwit (Limosa fedoa) nests primarily in temperate grasslands of northcentral United States (U.S.) and south-central Canada (i.e., mid-continental population) and winters primarily at coastal sites from central California south to central Sinaloa. There are also two small breeding populations that are highly disjunct from the mid-continental population├╣ one on the Alaska Peninsula (L. f. beringiae) and one at James Bay in Ontario, Quebec, and Nunavut. Alaskan birds are thought to winter at coastal sites from Washington south to central California, and James Bay birds are believed to winter at coastal sites of the southeastern U.S. and/or at sites along the U.S. Gulf of Mexico coast. The Marbled Godwit warrants conservation planning for several reasons: (1) its estimated global population is relatively small (140,000-200,000 birds), (2) its population trends and ecology are poorly understood, and (3) significant habitat loss or degradation appears to be eroding much of its breeding and wintering ranges. Primary mid-continental nesting habitat is native grassland encompassing complexes of relatively unvegetated, shallow wetlands. In these habitats, godwits face a number of threats, the most significant of which is habitat loss/ degradation due to agricultural conversion. Currently, the greatest threats to the two disjunct breeding populations are their small sizes. At wintering and coastal migration stopover sites, the most significant threats are development, recreation-based human disturbance, mariculture, and invasions of exotic plants and aquatic invertebrates. Threats at inland migration stopovers vary regionally, but the primary threat is inadequate water supply, which threatens the habitats themselves and exacerbates contamination, invasions of exotic plants, and disease outbreaks.
