BLM Colorado Special Status Plant Species Guide

Revised March 2025

This fully revised guide of the Bureau of Land Management (BLM) special status species plant list for Colorado is intended to assist agency biologists, consultants, and members of the public in the identification of special status plants in Colorado. This revision includes 74 plant species that are either listed as threatened or endangered under the Endangered Species Act (ESA), are proposed or candidates for listing under the ESA, have been delisted from the ESA within a 5-year period, or are designated as sensitive by the BLM. Many of these species occur primarily on the 8.3 million acres of land managed by the BLM in Colorado, positioning the agency with an important responsibility to influence their long-term conservation. It is the policy of the BLM to manage for proactive, landscape- and ecosystem-level, and scientifically informed conservation and recovery of special status species and their habitats.
