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.Read More
Cholla (Cylindropuntia imbricata) often becomes problematic on rangeland when desirable grasses are depleted by drought or over-utilization. The effectiveness of various management methods are discussed including hand and mechanical removal, herbicide rates and mixing guidelines, and management considerations for using herbicides to optimize cholla control.Read More
