The moist saline depressions and the dry beds of rivers are often covered by the greasewood (Sarcobatus
vermiculatus, Chenopodi-aceae), another shrubby chenopod that only grows 5 ft (1.5 m) tall but has a root system 7 ft (2 m) deep.
Fireman and Hayward (1952) demonstrated that soils beneath the salt-accumulating halophyte Sarcobatus
vermiculatus in the Escalente Desert, Utah, were much higher in exchangeable [Na.sup.+] percentage than under Artemisia tridentata or in the surrounding soils that were unvegetated (Table IV).
Table 1.--Description of cover types on study area to assess selection by kit foxes in southeastern Oregon, U.S.A., 2014-2015 Cover type Description Sagebrush shrubland Open to moderately dense (10-30% cover) (Sage) shrublands dominated by Artemisia tridentata or Artemisia arbuscula with grass and herbaceous layers present Mixed salt desert Open-canopied (10-20% cover) shrublands with scrub (Scrub) a mix of Atriplex confertifolia, Sarcobatus
vermiculatus, Chrysothamnus viscidiflorus, Atriplex tridentala, and Artemisia tridentata Sparsely vegetated A sparse cover (<10%) of Allenrolfea (Sparse) occidentalism Artemisia spp., Atriplex spp., Eriogonum spp., or Tetradymia spp.
vermiculatus shrubland occurred across elevations.
Common plants found on the Warm Springs winter range include Wyoming Big Sagebrush, Basin Big Sagebrush (Artemesia tridentata tridentata), Mountain Big Sagebrush (Artemesia tridentata vaseyana), Tall Threetip Sagebrush (Artemesia tripartita tripartita), Fourwing Saltbush (Atriplex canescens), Greasewood (Sarcobatus
vermiculatus), and a variety of for b and grass species.
Habitat was characterized by scattered shrubs including Chrysothamnus nauseosus (rabbitbrush), Sarcobatus
vermiculatus (greasewood), and Gutierrezia sarothrae (snakeweed), and an assortment of weeds on the roadside and severely deteriorated grassland of the Ninemile Valley adjacent to road 804 (Walker et al., 1998: figure 3).
