Control of Nitrogen Mineralization a Sagebrush Steppe Landscape
Ecology, 1989Factors controlling N turnover in sagebrush ecocystems are separable into two groups. The first group consists of properties that exhibit strong spatial patterning at a landscape scale but are temporally static at time scales of years or tens of years.

Comparing Burned and Mowed Treatments in Mountain Big Sagebrush Steppe
Environmental Management, 2012Fires in mountain big sagebrush [Artemisia tridentata spp. vaseyana (Rydb.) Beetle] plant communities historically shifted dominance from woody to herbaceous vegetation. However, fire return intervals have lengthened with European settlement, and sagebrush dominance has increased at the expense of herbaceous vegetation in some plant communities ...

Succession patterns following soil disturbance in a sagebrush steppe community
Oecologia, 1990A study was begun in 1976 to measure succession patterns following soil disturbance within a sagebrush community in northwestern Colorado. The principal hypothesis was that type of disturbance affects the direction of succession, resulting in different plant communities over time. Successional dynamics were studied through 1988.

Indicators of ecosystem function identify alternate states in the sagebrush steppe
Ecological Applications, 2011Models of ecosystem change that incorporate nonlinear dynamics and thresholds, such as state-and-transition models (STMs), are increasingly popular tools for land management decision-making. However, few models are based on systematic collection and documentation of ecological data, and of these, most rely solely on structural indicators (species ...

Cattle Grazing and Vegetation Succession on Burned Sagebrush Steppe
Rangeland Ecology and Management, 2014There is limited information about the effects of cattle grazing to longer-term plant community composition and herbage production following fire in sagebrush steppe. This study evaluated vegetation response to cattle grazing over 7 yr (2007–2013) on burned Wyoming big sagebrush (Artemisia tridentata ssp.

Aeolian sediment transport following wildfire in sagebrush steppe
Journal of Arid Environments, 2009Abstract Wind erosion of soil is an appreciable but unstudied event following fires in cold desert. We examined aeolian transport of sediment for 1 year following fire in semi-arid shrub steppe on loess soils in southern Idaho, USA. Sediment collectors were used to determine horizontal mass transport of soil and saltation sensors and anemometers were

A comparison of livestock grazing effects on sagebrush steppe, USA, and Patagonia steppe, Argentina
2003My comparison of plant traits showed that sagebrush steppe grasses have significantly higher forage quality than Patagonian grasses, based on measurements of tissue nitrogen and fiber content. Sagebrush steppe grasses also tend to be taller than Patagonian grasses.
