Endangered species conservation isn’t just about animals — plant species often become rare and endangered as well. Colorado is home to a number of rare plants that various state agencies, including the Colorado Department of Agriculture, the Colorado Department of Natural Resources, and Colorado State University’s Colorado Natural Heritage Program (CNHP) have been working to conserve. In our library you will find a number of resources that detail what Colorado is doing to conserve rare plants. (Publications without hyperlinks can be checked out in print).
