Glaucocarpum suffrutescens


A perennial herbaceous plant with clumped stems arising from a branching woody root crown. The flowers are light yellow or green-yellow in a raceme (cluster) at the end of the stems.

Distribution & Occurrence

State Range
  Utah
State Range of  Glaucocarpum suffrutescens
Habitat
  This species occurs in a desert shrubland, with occasional Utah Juniper and Pinyon Pine trees. It grows on clay soils with chips of white shale. The soil is derived from the Evacuation Creek Member of the Green River geological formation between 5,400-6,000 feet elevation.

Distribution
  Found in the Uintah Basin in Duchesne and Uintah counties, Utah. (State of Utah Natural Resources 2002)

Number Left
  Three known populations with a total number of individuals estimated at about 5,000 individuals. (USFWS 1994)

Conservation, Ecology & Research

Ecological Relationships
  Unknown.

Threats
  Oil and gas exploration, drilling, and production
Oil-shale mining and processing
Off-road vehicle use and surface disturbing activities associated with energy development
Building stone removal
(USFWS 1994)

Current Research Summary
  None known.

Current Management Summary
  Populations of this species are partially on the Uintah-Ouray Reservation, the naval oil shale reserve administered by the Department of Energy and the rest is either Bureau of Land Management or private land. Finally, a more accurate estimation of population distribution is recommended.

Research Management Needs
  Successful propagation protocols must be developed and more coordination is needed between the various agencies/tribes that manage this species.

Ex Situ Needs
  Limited success with ex situ propagation. This species should be studied further in the greenhouse.
