Sustainable Management of Non-Native Thistles on Colorado’s Western Slope

Sustainable Management of Non-Native Thistles on Colorado’s Western Slope

A research project was initiated on a 10,670-acre ranch near Cimmarron, Colorado to develop sustainable management strategies for musk and Canada thistle. Objectives of the study were three-fold: 1) Investigate invasive thistle distribution through geospatial analysis; 2) determine effects of musk thistle management on forage quality and native plant diversity; and 3) develop a sustainable invasive plant management plan for the ranch.
