Eriogonum visheri


The gullied ridges and eroded hills of South Dakota's Badlands National Park have the character of a moonscape. Almost no plant life can be found on these barren slopes, except the Dakota wild buckwheat, a wiry, inconspicuous little plant that makes a home in the badlands of North and South Dakota and adjacent Montana. An annual that completes its life cycle in one year, the Dakota wild buckwheat can occupy the constantly eroding badland habitat that otherwise provides unstable footing for longer-lived plants.

Distribution & Occurrence

State Range
  Montana
North Dakota
South Dakota
State Range of  Eriogonum visheri
Habitat
  Barren shale and clay outcrops of badlands, eroded hillsides, slopes of bluffs, and outwash fans at the base of slopes. Gravelly, clayey soils. Soils have high shrink-swell potential, are strongly calcareous and high in sodium, all of which may limit competition and succession. Typical habitat is at least 50% bare soil. Surrounding vegetation is mixed grass prairie. Elevation 1900-3100 ft.

Distribution
  Centered in western South Dakota (Corson, Hardin, Jackson, Meade, Mellette, Pennington, Perkins and Ziebach counties), to western North Dakota (Billings, Golden Valley, Grant, McKenzie, Montrail, Sioux and Slope counties), and southeastern Montana (Carter County).

Number Left
  Montana: one occurrence (Montana Natural Heritage Program 2002).
North Dakota: 14 populations (NatureServe 2001).
South Dakota: 79 populations (NatureServe 2001).

Conservation, Ecology & Research

Ecological Relationships
  The most closely related species, Eriogonum aliquantum, occurs in similar habitat in northeastern New Mexico (Reveal 1976).

Threats
  Invasion of barren habitat by exotic weeds that compete with E. visheri.

Current Research Summary
  Successfully propagated from seed using scarification pretreatment (Nebraska Statewide Arboretum).

Current Management Summary
 

Research Management Needs
