Dealing with the Triple Threat Invasion: Cheatgrass, Medusahead, & Ventenata

Invasive annual grasses such as cheatgrass (Bromus tectorum), medusahead (Taeniatherum caput-medusae), and ventenata (Ventenata dubia) are devastating western natural areas and rangeland at a landscape scale. These grass invasions favor further invasions while eliminating desirable vegetation and wildlife habitat. Further impacts include:

  • A continuous bed of fine fuel associated with an increase in frequency and intensity of rangeland wildfire
  • Significant reduction or elimination of desirable perennial species
  • Reduced forage quality for wildlife and livestock
  • Increased risks for wildlife and pollinator species
  • Resulting wildfires that are a threat to humans, wildlife, property and infrastructure.

Speakers will address all of these points, including current management tools for the “triple threat”, highlighting recent research conducted in multiple western states.
