Interpretive Summary: Revegetation of medusahead-invaded rangeland is needed to increase forage production, decrease the risk of wildfires, and improve wildlife habitat. Successful revegetation starts with effective control of medusahead. Prescribed burning followed by a fall application of a pre-emergent herbicide has been repeatedly demonstartated to effectively control medusahead. Desired vegetation should be seeded one year after pre-emergent herbicide application to reduce non-target herbicide damage. Introduced perennial bunchgrasses have been the most successful plant functional group at establishing after medusahead control and preventing re-invasion by medusahead. Post-seeding management should include spot-spraying medusahead patches in the revegetation project and short-term rest from grazing to allow seeded vegetation to establish.
