FACT SHEETS

Wildlife: Terrestrial and Endangered Resources Program. Download the fact sheet (145 KB, PDF)

Abstract: Wildlife: Terrestrial and Endangered Resources research is conducted on migratory birds, mammals, amphibians, and their habitats. Results complement and support the conservation and management efforts of Federal and State wildlife agencies, nongovernmental organizations, and international treaties.

Imperiled Species and Communities Threatened by Invasive Species. Download the fact sheet (2.7 MB, PDF)

Abstract: The impacts of invasive species on our economy and ecosystems are now a fact of life in the United States. Extensive studies have shown that the unchecked invasion of non-native species is causing billions of dollars worth of damage to U.S. agriculture, forestry, and human and wildlife health, as well as threatening the vital functions that natural ecosystems support. A less well known fact is that invasive species threaten one of our most precious natural resources -- imperiled species and communities.

Occupancy Models to Study Wildlife. Download the fact sheet (951 KB, PDF)

Abstract: Many wildlife studies seek to understand changes or differences in the proportion of sites occupied by a species of interest. These studies are hampered by imperfect detection of these species, which can result in some sites appearing to be unoccupied that are actually occupied. Occupancy models solve this problem and produce unbiased estimates of occupancy and related parameters. Required data (detection/non-detection information) are relatively simple and inexpensive to collect. Software is available free of charge to aid investigators in occupancy estimation.
