New invasive annual grass book addresses critical questions for western United States

FS News Posted on: January 20, 2016
BOISE, ID — Bromus species – such as cheatgrass – are exotic annual grasses that have become the dominant annual grasses in the western hemisphere. Their spread and impacts across the western U.S. continue despite the many attempts by land managers to control these species. A new book edited by scientists from the U.S. Geological Survey, U.S.

A new look at the race for survival: Cheatgrass biocontrol with “black fingers of death”

Science Spotlights Posted on: September 09, 2015
Cheatgrass is one of the most destructive plant invaders in the West with significant economic and ecological impacts on rangelands and agricultural lands. The seed pathogen "black fingers of death" is a promising tool under consideration for biocontrol of cheatgrass. Understanding the effects of slow-growing versus fast-growing pathogen strains may be the key to successfully slow down or stop cheatgrass seed germination.

Effects of resource availability and propagule supply on native species recruitment in sagebrush ecosystems invaded by Bormus tectorum

Publications Posted on: September 13, 2010
Resource availability and propagule supply are major factors influencing establishment and persistence of both native and invasive species. Increased soil nitrogen (N) availability and high propagule inputs contribute to the ability of annual invasive grasses to dominate disturbed ecosystems. Nitrogen reduction through carbon (C) additions can potentially immobilize soil N and reduce the competitiveness of annual invasive grasses.
