fresc.usgs.gov — Periodic fire is a natural part of sagebrush steppe ecosystems in the Great Basin. However, a suite of human-caused factors has dramatically changed fire regimes in many of these systems. Decades of fire suppression and livestock grazing have produced dense, single-aged sagebrush stands and invasion by cheatgrass (Bromus tectorum) has increased More...

www.umesc.usgs.gov — Eurasian Ruffe pose a threat to native fish because they(1) mature quickly, (2) have a high reproductive capacity, and (3) easily adapt to new environments. Ruffe were first detected in western Lake Superior in 1986. UMESC scientists are conducting research on various types of piscicides (chemicals that kill fish). They are attempting to develop More...
