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 — Pinon-juniper woodlands have expanded beyond their historical range in the western United States, due partly to land management practices such as fire suppression that began with settlements of the region in the late 1880s. This woodland expansion has replaced sagebrush steppe vegetation, leading to decreased wildlife habitat, soil seedbanks, and More...

www.werc.usgs.gov — This issue overview focuses on nonnative grass invasions and fire in the Mojave Desert, which appear to have been infrequent historically. When fires occurred, gaps of plant-free space separating individual shrubs, bunchgrasses, cacti, and trees, stopped the spread of fires like networks of small firebreaks. The increasing dominance of nonnative More...

www.umesc.usgs.gov — After a series of navigation dams were constructed in the Upper Mississippi and Illinois Rivers in the 1930s, aquatic vegetation flourished. Its distribution, however, has fluctuated drastically in the 1980s and 1990s. As the navigation system ages, the fate of this important ecosystem component is a growing concern. This issue overview's More...

www.umesc.usgs.gov — The diversity of habitat types, plants, and animals in the Upper Mississippi River has declined considerably over the last 50 years, creating loss of aquatic vegetation, loss of islands and side channels behind dams, and changes in river sediments, potentially caused by the method of managing water levels, which maintains artificially high water More...
