Medusahead & Barb Goatgrass
Medusahead (Taeniatherum caput-medusae) and barb goatgrass (Aegilops triuncialis) are two aggressive annual grasses that are negatively impacting rangelands across the western United States. These winter annuals establish and spread quickly, creating undesirable monocultures. Invasion of these species can result in the following: altered nutrient and hydrologic cycling, modified fire regimes, diminished wildlife habitat and reduced forage quality.
Reference the below publications, links and educational resources for information about these undesired rangeland grasses.
