MontBlanc1,2, Jeanne C. Chambers3, and Peter F. Brussard1 ABSTRACT.—Climate change and fire suppression have facilitated expansion of pinyon-juniper woodlands into sage- brush-steppe ecosystems of the Great Basin, USA, resulting in a loss of biological diversity. To assess the effects of using prescribed fire in restoration efforts, ant abundance, species richness, and composition were examined pre- and post-burn along the elevation and tree cover gradients encompassed by a pinyon-juniper woodland in a central Nevada watershed.
