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...

www.nwrc.usgs.gov — Cogongrass (Imperata cylindrica) is an agressive, perennial grass from Southeast Asia. Introduced into the United States on at least two separate occasions, this weed is currently invading Florida, Alabama, Mississippi, and Louisiana and has recently been discovered in East Texas. Cogongrass is considered one of the 10 worst weeds worldwide and is More...

www.werc.usgs.gov — This issues overview and its resources deal with the spread of nonnative grasses in the Sonoran desert of Arizona has increased the risk of devastating fires by ignited fuel. The saguaro cactuses and desert tortoises have suffered catastrophic population losses as a result of these fires fueled by nonnative grasses. Read more about nonnative More...

www.werc.usgs.gov — This resource provides an overview of the research on ways to prevent invasive annual grass invasions and restore invaded habitats, which has independently and repeatedly been identified by all land management agencies as a top national research priority. Annual grasses have invaded a number of shrub and forest ecosystems in western North America More...

www.werc.usgs.gov — USGS scientists are conducting research through the Joint Fire Science Program to determine if fire contributes most to plant invasion in low-nutrient soils by making available increased nutrients that invasive grasses may exploit more effectively than native flora. Soil nutrient changes can vary widely depending on soil properties and the amount More...

www.werc.usgs.gov — The sage grouse that occupies the Mono County area is described as the eastern subspecies of the greater sage-grouse (Centrocercus urophasianus urophasianus). The greater sage-grouse (Centrocercus urophasianus) is found in sagebrush (Artemisia spp.) dominated habitats across western North America. Sage grouse populations have declined dramatically More...

www.umesc.usgs.gov — This resource is a species profile and issue overview of the reed canary grass (Phalaris arundinacea). It discusses its increasingly dominating behavior in wet meadows in the Upper Midwest. Reed canary grass is highly tolerant to flooding, resistant to burning, and quickly forms virtual monocultures by shading native grasses and forbs with its More...

www.werc.usgs.gov — This web resource addresses the positive relationship between cheatgrass (Bromus tectorum) and fire frequency as a major concern for land managers in semi-arid shrublands throughout western North America, particularly in Great Basin sagebrush steppe. Management tools are needed to break this cycle, and in this project we will evaluate the use of More...
