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.
A scientific study has determined that survey methods designed for spotted owls do not always detect barred owls that are actually present in spotted owl habitat.
Description of research and monitoring work proposed for 2008 to combine hydrologic models with manatee distribution and movement models near and within Everglades National Park.
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.
These organisms have negative effects on local ecosystems, but we don't yet know how extensively they have spread. Here is a key to help people identify them.
This program provides management-oriented research and delivers information needed to prevent, detect, control, and eradicate invasive species, and to restore impaired ecosystems.
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.
