Exotic Annual Grasses in Western Rangelands: Predicting Resistance and Resilience of Native Ecosystems to Invasion (Draft)
Abstract
Bromus tectorum (hereafter referred to as Bromus) is a non-native annual grass from the Mediterranean region that arrived in the United States in the late 19th century and soon spread throughout the western states. Bromus now dominates millions of hectares of low- and mid-elevation landscapes. Where this occurs, native plant and animal diversity is reduced and sometimes extirpated, fire frequencies are increased, community productivity is decreased, and soil biota and nutrient cycles are altered. This has led to many research efforts to understand the impact of Bromus on native ecosystems and to identify ways to prevent invasion and/or to restore invaded landscapes.
