Wildfire Impacts, and Post-Fire Rehabilitation and Restoration
Science Center Objects
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.
Major conservation investments are often directed towards stabilizing soils and promoting native or desirable perennial plant communities that support wildlife and sustain livestock values under current and future conditions. My research group is evaluating risks of soil erosion and exotic-plant invasions, and approaches for increasing the effectiveness of post-fire seeding, herbicide applications, and also effects of grazing-resumption timing. Our activities contribute to the information base needed by managers to preserve or restore resistance and resilience to burned rangeland landscapes. Research sub-topics include:
Post-fire seeding, planting, and herbicide spraying effectiveness; finding ways to improve success
Seed-source effects, determined from actual seedings and through common-garden studies
Post-fire wind erosion: causes, consequences, and management implications
Developing monitoring approaches for post-fire landscapes
Assessing bunchgrass maturity and readiness for grazing

Date published: November 16, 2017Status: ActivePlant-Soil-Environment Laboratory (FRESC)
We produce basic and applied science needed to manage landscapes in ways that make them resistant and resilient to stressors such as wildfire, exotic plant invasions, drought, and temperature extremes. These stressors impact ecosystem productivity and functioning and pose costly risks to human health and safety in the western United States. We team with other state and federal agencies to find...

A conservation paradox in the Great Basin—Altering sagebrush landscapes with fuel breaks to reduce habitat loss from wildfire
Interactions between fire and nonnative, annual plant species (that is, “the grass/fire cycle”) represent one of the greatest threats to sagebrush (Artemisia spp.) ecosystems and associated wildlife, including the greater sage-grouse (Centrocercus urophasianus). In 2015, U.S. Department of the Interior called for a “science-based strategy to...

Plant community resistance to invasion by Bromus species – the roles of community attributes, Bromus Interactions with plant communities, and Bromus traits
The factors that determine plant community resistance to exotic annual Bromus species (Bromushereafter) are diverse and context specific. They are influenced by the environmental characteristics and attributes of the community, the traits of Bromus species, and the direct and indirect interactions of Bromus with the plant community. Environmental...
Chambers, Jeanne; Germino, Matthew J.; Belnap, Jayne; Brown, Cynthia; Schupp, Eugene W.; St. Clair, Samuel B Challenges of establishing big sgebrush (Artemisia tridentata) in rangeland restoration: effects of herbicide, mowing, whole-community seeding, and sagebrush seed sources
The loss of big sagebrush (Artemisia tridentata Nutt.) on sites disturbed by fire has motivated restoration seeding and planting efforts. However, the resulting sagebrush establishment is often lower than desired, especially in dry areas. Sagebrush establishment may be increased by addressing factors such as seed source and condition or management...
Brabec, Martha M.; Germino, Matthew J.; Shinneman, Douglas J.; Pilliod, David S.; McIlroy, Susan K.; Arkle, Robert S. Wind erosion from a sagebrush steppe burned by wildfire: measurements of PM10 and total horizontal sediment flux
Wind erosion and aeolian transport processes are under studied compared to rainfall-induced erosion and sediment transport on burned landscapes. Post-fire wind erosion studies have predominantly focused on near-surface sediment transport and associated impacts such as on-site soil loss and site fertility. Downwind impacts, including air quality...
Wagenbrenner, Natalie S.; Germino, Matthew J.; Lamb, Brian K.; Robichaud, Peter R.; Foltz, Randy B. Transport of biologically important nutrients by wind in an eroding cold desert
Wind erosion following fire is an important landscape process that can result in the redistribution of ecologically important soil resources. In this study we evaluated the potential for a fire patch in a desert shrubland to serve as a source of biologically important nutrients to the adjacent, downwind, unburned ecosystem. We analyzed nutrient...
Sankey, Joel B.; Germino, Matthew J.; Benner, Shawn G.; Glenn, Nancy F.; Hoover, Amber N. A common-garden study of resource-island effects on a native and an exotic, annual grass after fire
Plant-soil variation related to perennial-plant resource islands (coppices) interspersed with relatively bare interspaces is a major source of heterogeneity in desert rangelands. Our objective was to determine how native and exotic grasses vary on coppice mounds and interspaces (microsites) in unburned and burned sites and underlying factors that...
Hoover, Amber N.; Germino, Matthew J. Aeolian nutrient fluxes following wildfire in sagebrush steppe: Implications for soil carbon storage
Pulses of aeolian transport following fire can profoundly affect the biogeochemical cycling of nutrients in semi-arid and arid ecosystems. Our objective was to determine horizontal nutrient fluxes occurring in the saltation zone during an episodic pulse of aeolian transport that occurred following a wildfire in a semi-arid sagebrush steppe...
