Appendix 4. UNPS Rare Plant List: Need Data List
The following table includes 115 species with three or more ranking criteria scored as “unknown”. A large number
of these species have only recently been named or discovered within Utah, and additional field surveys are needed to
confirm their abundance, distribution, habitat needs, life history patterns, potential threats, and trends. Some species
on the list have taxonomic questions that still need to be resolved. All of the plants included here have the potential
to be ranked as extremely high or high priority, or as watch species, once needed studies are completed. Species are
arranged alphabetically by family and species. Additional information is provided on county-level distribution (see
Table 3 for codes) and data needs. Legal Status: Bureau of Land Management (BLM) and US Forest Service (USFS)
Sensitive = S; US Fish and Wildlife Service (USFWS) Candidate = C.
