Developing and optimizing shrub parameters representing sagebrush (Artemisia spp.) ecosystems in the northern Great Basin using the Ecosystem Demography (EDv2.2) model [PDF]

Geoscientific Model Development, 2019
Ecosystem dynamic models are useful for understanding ecosystem characteristics over time and space because of their efficiency over direct field measurements and applicability to broad spatial extents.

Ecological potential fractional component cover based on Long-Term satellite observations across the western United States

Ecological Indicators, 2021
Rangelands have immense inherent spatial and temporal variability, yet land condition and trends are often assessed at a limited number of spatially “representative” points.

Post-Fire Vegetation Response in a Repeatedly Burned Low-Elevation Sagebrush Steppe Protected Area Provides Insights About Resilience and Invasion Resistance

Frontiers in Ecology and Evolution, 2020
Sagebrush steppe ecosystems are threatened by human land-use legacies, biological invasions, and altered fire and climate dynamics. Steppe protected areas are therefore of heightened conservation importance but are few and vulnerable to the same impacts ...

Sagebrush recovery patterns after fuel treatments mediated by disturbance type and plant functional group interactions

Ecosphere, 2021
Fire and fuel management is a high priority in North American sagebrush ecosystems where the expansion of piñon and juniper trees and the invasion of nonnative annual grasses are altering fire regimes and resulting in loss of sagebrush species and ...

SCALING UP SAGEBRUSH CHEMISTRY WITH NEAR-INFRARED SPECTROSCOPY AND UAS-ACQUIRED HYPERSPECTRAL IMAGERY [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2021
Sagebrush ecosystems (Artemisia spp.) face many threats including large wildfires and conversion to invasive annuals, and thus are the focus of intense restoration efforts across the western United States. Specific attention has been given to restoration

Trends in soil microclimate and modeled impacts on germination timing in the sagebrush steppe

Ecosphere, 2022
Past and projected changes in climate affect soil microclimate, impacting seeds that use soil moisture and soil temperature as cues for germination.

Data set on the effects of conifer control and slash burning on soil carbon, total N, organic matter and extractable micro-nutrients

Data in Brief, 2017
Conifer control in sagebrush steppe of the western United States causes various levels of site disturbance influencing vegetation recovery and resource availability.

Interannual variation in climate contributes to contingency in post‐fire restoration outcomes in seeded sagebrush steppe

Conservation Science and Practice, 2022
Interannual variation, especially weather, is an often‐cited reason for restoration “failures”; yet its importance is difficult to experimentally isolate across broad spatiotemporal extents, due to correlations between weather and site characteristics ...

Soil characteristics are associated with gradients of big sagebrush canopy structure after disturbance

Ecosphere, 2019
Reestablishing shrub canopy cover after disturbance in semi‐arid ecosystems, such as sagebrush steppe, is essential to provide wildlife habitat and restore ecosystem functioning.

The Effect of Seeding Treatments and Climate on Fire Regimes in Wyoming Sagebrush Steppe

Fire, 2021
Wildfire size and frequency have increased in the western United States since the 1950s, but it is unclear how seeding treatments have altered fire regimes in arid steppe systems.
