Botanical research in the state of Colorado has identified many plant species considered to be rare or uncommon in the state by the Colorado Natural Heritage Program, who maintains a tracking list and serves as the central data repository for Colorado’s rare flora. Many of these species are also considered species of conservation concern by the U.S. Fish and Wildlife Service (USFWS), the U.S. Forest Service (USFS), the Bureau of Land Management (BLM), and the Colorado Department of Natural Resources (CNHP 2022).
The Colorado Rare Plant Guide was originally produced through the efforts of the Colorado Rare Plant Technical Committee, a committee representing government and private interests and concerned with protecting Colorado's flora. Continuing support for updates to the guide has been provided by numerous partners. The Committee anticipated that a guide to Colorado's rarest plants would facilitate the collection of botanical data, be indispensable to the establishment of conservation priorities, and enable informed land management decisions.
