Rest-rotation grazing, defined as lack of livestock grazing in a pasture for 15-18 months, is suggested to improve the quality of sagebrush, shrubland, and grassland habitat for a wide range of species. However, little work has been done to evaluate impacts of rest-rotation grazing on migratory avian species which serve as indicators of sagebrush ecosystem integrity. Evaluating the impacts of rest-rotation grazing using indicator species can provide valuable insight into how rest-rotation grazing may affect multiple species in the ecosystem.Our research is focused on how different grazing systems, rest-rotation and traditional, change songbird community structure (e.g., species abundance and richness). Traditional...

The project will use baseline data on pre-restoration measures of baseline hydrology and water quality to evaluate the impacts of large scale wetland and prairire restorations on hydrology and water quality including: recovery of key habitats and functions; abilities of wetlands to buffer variable water flows; ability of groundwater to buffer water flows; groundwater and surface water quality; changes in groundwater movement; rates of denitrification and carbon storage/ transport.

Temperate grassland ecosystems are imperiled globally, and habitat loss in North America has resulted in steepdeclines of endemic songbirds. Commercial livestock grazing is the primary land use in rangelands that supportremaining bird populations. Some conservationists suggest using livestock as “ecosystem engineers” to increasehabitat heterogeneity in rangelands because birds require a spectrum of sparse to dense vegetation cover.However, grazing effects remain poorly understood because local studies have not incorporated broad-scaleenvironmental constraints on herbaceous growth. We surveyed grassland birds across a region spanning26 500 km2 in northeast Montana, United States to assess how distribution and abundance...
