America's Bird Habitats
The State of the Birds report uses birds as indicators of habitat health by examining population trends of obligate species for a single habitat (all the bird species dependent primarily on that habitat for survival). The report includes bird population indicators for five habitats—grasslands, aridlands, forests, wetlands, and coasts (the last including a sub-indicator for long-distance migrant shorebirds).
The report also assesses bird populations on oceans and islands. Although broad and deep, long-term populating monitoring doesn’t exist for these two habitats, the report presents regional analyses and discussion of seabird and island bird conservation issues.
