Tier 1 and Tier 2 Plant Species of Greatest Conservation Need

Colorado’s 2015 State Wildlife Action Plan
Table 1. Colorado Plants of Greatest Conservation Need
NatureServe status ranks are: 1 = Critically Imperiled; 2 = Imperiled; 3 = Vulnerable; 4 = Apparently Secure; 5 = Demonstrably Secure; T =
subspecies; Q = taxonomic question; SNA = Not Applicable (not in Colorado). Agency status indicates federal listing under the U.S.
Endangered Species Act (LE = Listed Endangered; LT = Listed Threatened; C = Candidate for listing), and/or inclusion on the Sensitive
Species lists of the Bureau of Land Management (BLM) Colorado Office or US Forest Service (USFS) Region 2. The percent of a species’
range in Colorado is calculated as: Endemic = 100% of range within Colorado; Very High = 75-99% of range within Colorado; High = 5075% of range within Colorado; Medium = 25-50% of range within Colorado; Low = < 25% of range within Colorado (source: Colorado
Natural Heritage Program).
