An accuracy assessment of satellite-derived rangeland fractional cover
Ecological IndicatorsSatellite-derived maps of vegetation cover provide detailed information about vegetation spatiotemporal patterns and are increasingly used to better understand and manage rangelands. Despite their utility, questions remain regarding the regional and site

Restoration Ecology, EarlyView.Abstract Introduction Endangered fish species, such as Delta smelt (Hypomesus transpacificus), in the San Francisco Estuary are threatened by a multitude of anthropogenic stressors. Tidal wetland restoration can partially mitigate these stressors by increasing food availability of aquatic invertebrate prey, but the efficacy of restoration remains ...

Using Aerial LiDAR Data to Map Vegetation Structural Types in Arid and Semi-Arid Rangelands
Remote SensingRangelands occupy over half of the Earth’s terrestrial surface and play an important role in supporting biodiversity and livelihoods. However, widespread degradation—particularly in arid and semi-arid regions—has compromised their ecological function ...

Restoration ecology in conflict along the Colorado front range
Restoration Ecology, EarlyView.Abstract Introduction Cheatgrass (Bromus tectorum) is a challenge to restoration in western North America. It attracts the attention of academic and government research scientists, weed managers, and chemical companies. Attempts to control it cause conflicts among these groups.

Restoration Ecology, EarlyView.Abstract Introduction The invasion of the winter annual grass Cheatgrass (Bromus tectorum L.) reduces native plant biodiversity and increases wildfire risk in western North America. Seed‐based restoration often fails to increase native plant recruitment in degraded, Cheatgrass‐invaded areas.

Estimating Woody Vegetation Cover in Arid and Semi-Arid Rangelands
Ecological IndicatorsMeasuring woody vegetation cover (WVC) is an essential part of ecological monitoring in rangelands. While continental-scale products that map vegetation cover from satellite remote sensing are available, it is uncertain whether these products are well suited for analyses at the sub-catchment and property scale. We evaluated a novel approach to regional-

Restoration Ecology, EarlyView.Abstract Introduction Biocrusts are increasingly recognized for their contribution to soil stability, hydrology, nutrient cycling, and energy balance in drylands, yet practical field methods for assessing functional roles are limited. Existing approaches typically rely on cover estimates, taxonomic identification, or laboratory analyses, providing ...

Restoration Ecology, EarlyView.Abstract Introduction Successful restoration of terrestrial drylands depends on stable, fertile soils that retain water. These functions are provided by biological soil crusts (biocrust), suggesting their reestablishment is a critical step in dryland restoration.
