FY2011Increasingly large wildfires in the Great Basin and Columbia Plateau have led to large dust storms in areas historically without them. Large dust storms have adversely affected human health, energy production operations, soil fertility, and mountain snowpack hydrology. USGS research efforts have investigated the causes and consequences of post-fire dust storms. Publications from this work are being used by managers with the Bureau of Land Management, Department of Energy, and other land managers to develop management practices that will minimize dust production.

Aspen is a highly valued tree species in western forests, but it has been declining due to drought, herbivory, and fire suppression. Fire suppression has contributed to aspen’s decline because post-fire environments provide more opportunities for aspen to regenerate, both by resprouting and by seed. Regeneration from seed in these post-fire settings is particularly valuable because it increases aspen population genetic diversity and resilience. However, natural seeding events are not common, and mortality rates for seedlings are quite high. Nursery-grown seedlings provide a promising alternative and an opportunity for assisted migration, but planting protocols have not been well developed and mortality rates for...

We conducted a study to evaluate the relative importance of topography, grazing, the location of individual plants (microsite), and plant species in controlling the spatial variability of soil organic matter in shortgrass steppe ecosystems. We found that the largest spatial variation occurs in concert with topography and with microsite-scale heterogeneity, with relatively little spatial variability due to grazing or to plant species. Total soil C and N, coarse and fine particulate organic matter C and N, and potentially mineralizable C were significantly affected by topography, with higher levels in toeslope positions than in midslopes or summits. Soils beneath individual plants (Bouteloua gracilis and Opuntia polyacantha)...
