Status: Active Weed-Suppressive Bacteria – Testing a Control Measure for Invasive Grasses in the West
Recent popular news has implied that Weed-Suppressive Bacteria (WSB) holds promise for cheatgrass control, yet a lack of peer-reviewed research exists to support this claim. USGS researchers stepped up to the challenge of objectively and rigorously evaluating the effectiveness of WSB for controlling exotic annual grasses, such as...

Status: Active Cheatgrass and Medusahead
Invasive annual grasses, such as cheatgrass (Bromus tectorum) and medusahead (Taeniatherum caput-medusae), are one of the most significant stressors to rangeland ecosystems in the western U.S. Their expansion and dominance across this area are the most damaging ecosystem agents on this iconic landscape.

Status: Active Wildfire Impacts, and Post-Fire Rehabilitation and Restoration
Land use and unintentional (e.g., wildfire) disturbances are increasingly dominant factors affecting land-use planning and management of semiarid landscapes, particularly in sagebrush steppe rangelands. In the last 10-20 years, wildfires are occurring more frequently and increasingly in very large burn patches.

Climate responses of sagebrush are needed to inform land managers of the stability and restoration of sagebrush ecosystems, which are an important but threatened habitat type. We evaluated climate responses of sagebrush using two approaches: (1) experimental manipulations of temperature and precipitation for natural plants in the field, and (2) assessment of how climate adaptation and weather...

Intraspecific variation mediates density dependence in a genetically diverse plant species
Interactions between neighboring plants are critical for biodiversity maintenance in plant populations and communities. Intraspecific trait variation and genome duplication are common in plant species and can drive eco-evolutionary dynamics through genotype-mediated plant–plant interactions. However, few studies have examined how species-wide...

A chemical and bio‐herbicide mixture increased exotic invaders, both targeted and non‐targeted, across a diversely invaded landscape after fire
QuestionsInvasive‐plant treatments often target a single or few species, but many landscapes are diversely invaded. Exotic annual grasses (EAGs) increase wildfires and degrade native perennial plant communities in cold‐desert rangelands, and herbicides are thus sprayed to inhibit EAG germination and establishment. We asked how EAG target and non‐...

Weather and distance to fire refugia limit landscape‐level occurrence of fungal disease in an exotic annual grass
The enemy release hypothesis proposes that invasion by exotic plant species is driven by their release from natural enemies (i.e. herbivores and pathogens) in their introduced ranges. However, in many cases, natural enemies, which may be introduced or managed to regulate invasive species, may fail to impact target host populations. Landscape...
