Vegetation Recovery on Abandoned Oil and Gas Well Sites is Variable on Colorado Plateau
Recovery of vegetation on plugged and abandoned oil and gas well sites on the Colorado Plateau is influenced by time, moisture, nonnative plants and the type of plant community that was originally in place before well sites were constructed, according to a recently published study by the U.S. Geological Survey.

Future Temperature and Soil Moisture May Alter Location of Agricultural Regions
Future high temperature extremes and soil moisture conditions may cause some regions to become more suitable for rainfed, or non-irrigated, agriculture, while causing other areas to lose suitable farmland, according to a new U.S. Geological Survey study.

Increases in Wildfire-Caused Erosion Could Impact Water Supply and Quality in the West
A growing number of wildfire-burned areas throughout the western United States are expected to increase soil erosion rates within watersheds, causing more sediment to be present in downstream rivers and reservoirs, according to a new study by the U.S. Geological Survey.

Changing Temperatures and Precipitation May Affect Living Skin of Drylands
Arid and semiarid ecosystems are expected to experience significant changes in temperature and precipitation patterns, which may affect soil organisms in ways that cause surfaces to become lighter in color and thus reflect more sunlight, according to a new U.S. Geological Survey study.

A River Ran Through It and Brought Life, At Least for a While
In 2014, a large pulse of water was released into the mostly dry delta of the Colorado River along the U.S.-Mexico border. U.S. Geological Survey scientists are studying the effects of the pulse on the environment as part of a historic, bi-national collaborative effort. The pulse flow and the need to study its effects were accepted as part of the Minute 319 of the 1944 U.S.-Mexico Water Treaty.
