Currently known from 11 occurrences in Mesa County, Colorado and along an 8 km stretch of the Colorado River Canyon (Professor Valley) in adjacent Grand County, Utah. Several of the occurrences are within a 2 km separation distance and could be combined in the future. The Dolores River Canyon, where most of the plants occur, is heavily grazed, and L. dolorensis tends to be found on sites that are physically inaccessible to cattle, in protected spots within larger vegetation, or along roadsides.
Threats include livestock grazing (Atwood 1991).
There are three known sites (Von Bargen 1997).
There is no formal management plan.
Research needs include understanding reproductive biology and ecology, habitat requirement, relationships with other species and population dynamics.
Seed collection and storage.
