Grazing Impacts on Wetland Surface Microtopography

Submitted by Anonymous (not verified) on

Wyoming’s high desert riparian areas cover less than 1% of the landscape but account for up to 20% of forage. Livestock spend disproportionate time in these areas, inflicting disproportionate ecological impact by grazing and trampling, cited causes of increased riparian erosion and hummocking [citations 1-5]. Wetland hummocks are elevated soil pedestals separated by inter-hummock channels draining the wetland and eroding the organic soils that are the “sponge” for holding water in the system and prolonging streamflow that wildlife (and humans) depend on.

Monitoring Change in the Bureau of Land Management (BLM) National Monuments

A remote sensing project in cooperation with Northern Arizona University and the BLM detects newly created networks from illegal human activities: vehicular routes, human trails, and accumulations of litter, debris, and hazardous materials. The project will assist in evaluating the health of the landscape and public enjoyment of national monuments.
