Eriogonum gypsophilum


Eriogonum gypsophilum, known commonly as gypsum wild buckwheat, has only three known populations, all exclusively located in Eddy County, New Mexico. Populations are limited to growing on a specific soil composition, gypsum, a mineral commonly used in drywall and plaster. This area of New Mexico is also suitable for mineral development of gypsum, as well as oil and gas. These profitable land uses have been deemed to be serious potential threats to gypsum wild buckwheat populations, and consequentially large portions of these habitats are protected by the Bureau of Land Management.

Distribution & Occurrence

State Range
  New Mexico
State Range of  Eriogonum gypsophilum
Habitat
  Found only in southeastern New Mexico on gypsum soils and outcrops in the Chihuahuan Desert.

Distribution
  Three populations of Eriogonum gypsophilum are known to exist, all found in Eddy County, New Mexico. These populations are found at Seven River Hills, Black River, and Ben Slaughter Draw.

Number Left
  Each population of E. gypsophilum contains between 11,000 and 18,000 plants (USFWS).

Conservation, Ecology & Research

Ecological Relationships
  Climate for E. gypsophilum is semi-arid. Individuals mainly reproduce via asexual cloning from rhizomes. However, reproduction through seed may be possible in years where the climate favors seed germination (USFWS).

Threats
  • Habitat destruction through mineral extraction of gypsum, oil, and gas.

• Surface disturbances such as off-road vehicle use, camping, and plant collection.

Current Research Summary
  Research has been carried out by the US Fish and Wildlife Service in New Mexico. A recovery plan for E. gypsophilum was applied in 1984, with a recent 5-year review published in 2007 (referenced throughout this profile as "USFWS"). Further research outside governmental agencies is unknown.

Current Management Summary
  USFWS reports that the “federal regulatory mechanisms have been effective in removing or managing many of the threats” to E. gypsophilum. These include the Special Management Area Restrictions which limit “surface occupancy” for all three areas. As a result of this, they recommend the delisting of the “threatened” status. The report notes some obscurity as to whether these restrictions will continue after the species is delisted.

Research Management Needs
  Ensure continued federal protection under Special Management Area Restrictions, even after the species is delisted from the threatened and endangered list.

Monitoring Efforts
  Monitoring efforts are carried out by the U.S. Fish and Wildlife Service. Continued observational studies by this organization would be desirable.

Ex Situ Needs
  Past ex situ work has been carried out for this species, and as such further work is not recommended.
