Western Great Basin Wetlands Biodiversity Initiative
Completed
The western Great Basin Region is among the driest in North America. Wetlands of this area are of four types: large deep lakes, riparian areas, shallow alkali lakes, and complexes of natural and managed wetlands. While critical contributors to North American biodiversity, these wetlands are increasingly threatened and vary in quality and quantity from year to year. Western Great Basin wetlands provide critical breeding and migration sites for wading birds and shorebirds, yet little is known about their needs or habits. There is no management paradigm for species using these highly variable wetlands at any scale, much less guidance for dealing with changes in habitat quality or quantity. Shorebirds, the most numerous of birds inhabiting western Great Basin wetlands, are among the world's most mobile organisms. In most cases, individuals spend parts of their lives in different nations and ecotypes. In order to plan for conservation of these critical resources, it is essential to understand dynamics of avian movements across different patches of a landscape, connectivity among landscapes of a region, and movements across regions. Thus the goal of this project is to examine wetland viability and connectivity in the western Great Basin using a large-scale, landscape-level approach. This study documents the breeding and post-breeding phenology of use of the area by shorebirds, as well as the regional dispersal and movements of individuals among the most prominent wetland sites of eastern Oregon, northern California and Nevada. Our work focuses on three species of shorebird: American avocet (Recurvirostra americana), willet (Cataptrophorus semipalmatus), and killdeer (Charadrius vociferus).
