Recent physical changes over time, including trends toward earlier snowmelt runoff, decreasing river ice, and increasing spring water temperatures, may affect salmon populations; we want to know how important these effects are.
Article from Status and Trends of the Nation's Biological Resources on the serious impacts to river systems due to damming and flow regulation, and rehabilitation, monitoring, and research on such rivers.
We conducted a national landowner survey, evaluated short-term vegetation responses to land management practices (primarily grazing, haying, and burning), and initiating a long-term vegetation monitoring study for wetland buffers.
Description of research program for immediate and long-term management of grizzly bears (Ursus arctos horribilis) inhabiting the Greater Yellowstone Ecosystem. Includes links to reports in PDF format and cooperating organizations.
Links to research projects that will improve the ability to detect, monitor, and predict the effects of invasive species, including exotic animals, on native ecosystems of the Pacific Southwest (California, Nevada, Utah, and Arizona).
Will salt marshes survive if sea level rises quickly? The answer depends on whether the areas surrounding them can allow salt marsh fauna and flora to migrate there. Local topography, both natural and manmade, is the main factor limiting this migration.
