Our objective is to determine if and how these processes operate in shrub steppe ecosystems in Idaho by monitoring nesting success of shrub-steppe obligate species (Brewer's Sparrows, Spizella breweri, Sage Sparrows, Amphispiza belli, and Sage Thrashers, Oreoscoptes
In contrast, spatial measures of habitat richness and texture in the landscape were significant only at large spatial scales, Abundance of Horned Larks, Western Meadowlarks (Sturnella neglecta), and Brewer's Sparrows, but not Sage Thrashers (Oreoscoptes montanus) or Sage Sparrows, was positively correlated with changes toward stable habitats.

Sage Sparrows (Amphispiza belli) and Brewer's Sparrows (Spizella breweri) were the most abundant bird species breeding in the area, and Horned Larks (Eremophila alpestris) and Sage Thrashers (Oreoscoptes
montanus) were also common.
