Composite habitat condition for Great Basin watersheds

Percentage of watersheds in the Great Basin by combined classes of habitat abundance and risk that habitats will be displaced by cheatgrass, summarized for each of the five groups of species of conservation concern (from Wisdom and others 2005a). Total number of watersheds for each species group is given below the group name.
