Research
Research in our lab focuses on integrating tools (e.g. prevention; chemical, mechanical, and biological control; prescribed fire, revegetation) to manage invasive plants on rangeland in Montana. We aim to find ecologically-based, economically viable means to control invasive plants while maintaining or restoring desirable vegetation that meets management objectives.
| Current Research |
This section is in development. Check back for updates on our research including revegeting rangelands infested with annual grasses; herbicide efficacy trials; plant competition studies (see photos in right panel). |
