www.werc.usgs.gov — This web resource lists research projects related to detailed studies of fire history and fire ecology in the Sierra Nevada forests, the California shrublands, and the Mojave and Sonoran deserts. Researchers at the Western Ecological Research Center (WERC) are making contributions to this effort through Knowledge, forming the basis for new More...
Publisher: USGS | Science Center: Northern Prairie Wildlife Research Center (NPWRC, Jamestown) | Format: URL
www.npwrc.usgs.gov — This research project evaluates the effects of prescribed fire on the biological control of an invasive species, leafy spurge (Euphorbia esula). This project evaluates the effect of prerelease burning on establishment of flea beetle (Aphthona nigriscutis) colonies and the ability of established colonies to survive prescribed fire.

www.npwrc.usgs.gov — Alien Plants Ranking System (APRS) is a computer-implemented system to help land managers make difficult decisions concerning invasive nonnative plants. Land managers must focus their limited resources, targeting the species that cause major impacts or threats to resources within their management, or the species that impede attainment of More...
Publisher: USGS | Science Center: Fort Collins Science Center (FORT, Ft. Collins) | Format: URL
www.fort.usgs.gov — This web resource is a compilation of research projects related to Energy, Land Use, and Sagebrush Ecosystems. Investigators at the USGS Science Centers (FORT and FRESC), and Central Regional Office have brought biological and ecosystem research and mapping expertise to a partnership with the Bureau of Land Management, Wyoming Game and Fish More...
Publisher: USGS | Science Center: Forest and Rangeland Ecosystem Science Center (FRESC, Corvallis) | Format: URL
sagemap.wr.usgs.gov — SAGEMAP - Spatial Data for Sage Grouse and Shrubsteppe Systems is needed for research and management of sage grouse and sagebrush steppe habitats in the western United States. This website is a product of the NBII Great Basin Information Project. Find out more from this resource on sage grouse as endangered species, habitat information, More...
Publisher: USGS | Science Center: Upper Midwest Environmental Sciences Center (UMESC, LaCrosse) | Format: URL
www.umesc.usgs.gov — This web resource provides decision makers with the information needed to maintain the Upper Mississippi River System as a viable multiple-use large river ecosystem. This resource also includes Data and sampling information, publication links, reports, other related documents and statistics, as well as links to field stations and other projects More...

www.umesc.usgs.gov — Presently, the Long Term Resource Monitoring Program (LTRMP) conducts annual monitoring of vegetation using a stratified random sampling method (Yin et al. 2000) in five study reaches of the Upper Mississippi River System: Navigation Pools 4, 8, 13, and 26 on the Mississippi River; and La Grange Pool on the Illinois River. The LTRMP will continue More...

www.werc.usgs.gov — Fire occurs in many North American ecosystems, and most of these systems are resilient to fires that occur within a broad range of variability in frequency and intensity. In a recent USFS publication (General Technical Report PNW-GTR-779, ), USGS scientist Jon Keeley led a team of scientists from various agencies and academic institutions in More...
June 20 2008 | Publisher: USGS | Science Center: Fort Collins Science Center (FORT, Ft. Collins) | Format: URL
www.fort.usgs.gov — This report provides a preliminary review of adaptation options for climate-sensitive ecosystems and resources in the United States. The term "adaptation" in this document refers to adjustments in human social systems (e.g., management) in response to climate stimuli and their effects. Since management always occurs in the context of desired More...
November 2007 | Publisher: Academic Institution (Sage-grouse Restoration Project (SGRP), Utah State University) | Format: .PDF
sgrp.usu.edu — The greater sage-grouse (Centrocercus urophasianus) and the Gunnison sage-grouse (C. minimus) are species of concern because of their population declines and shrinking geographic distributions. Of continuing interest is the question of population abundance and trends. This publication answers the questions that deal with sage-grouse population, More...
July 2007 | Publisher: Other (Ecological Society of America (ESA) Journal) | Format: URL
www.esajournals.org — Periodic wildfire maintains the integrity and species composition of many ecosystems, including the Mediterranean-climate shrublands of California. However, human activities alter natural fire regimes, which can lead to cascading ecological effects. Increased human ignitions at the wildland-urban interface (WUI) have recently gained attention, but More...
