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.
Shrub-steppe lands typically consisted of a mixture of native plants such as sagebrush Artemisia tridentata, bitterbrush Purshia tridentata, green rabbitbrush
Chrysothamnus viscidiflorus, and bunch grasses, and to varying extents exotic invasive species such as cheat grass Bromus tectorum, tumble mustard Sisymbrium altissimum and Russian thistle Salsola kali.
The flat (100 to 200 m elevation) lake basin is dominated by shrubsteppe including Big Sagebrush, rabbitbrush (
Chrysothamnus spp.), Western Needle-and-Thread (Stipa comata), and introduced Cheatgrass (Bromus tectorum; Clarke and Bryce 1997).

Chrysothamnus and Sarcobatus.
