Erika Geiger, Ph.D.
Erika Geiger is a Supervisory Biologist at the USGS Canyonlands Research Station (CRS) in Moab, UT.
Erika received her BA in Biology from the University of Colorado in Boulder in 1997 and her Masters in Range Management (2002) and PhD in Natural Resources (2006) from the University of Arizona. She has worked in primarily arid or seasonally water-stressed systems including mesquite savannas in southern Arizona and savannas in the central highlands of Brazil investigating the role of invasive species, fire, and disturbance on native vegetation in these systems. After returning to the U.S. from a postdoc in Brazil she switched from research to management and is currently the Station Manager at the Southwest Biological Science Center – Canyonlands Research Station in Moab, Utah.

Biological Soil Crust ("Biocrust") Science
Biological soil crusts (biocrusts) are commonly found on the soil surface in arid and semi-arid ecosystems (collectively called drylands). Biocrusts can consist of mosses, cyanobacteria, lichens, algae, and microfungi, and they strongly interact with the soil. These organisms or consortium of disparate organisms, depending on the specific biocrust, are important to the functioning of ecosystems...
Long-Term Vegetation Change on the Colorado Plateau
The Colorado Plateau, centered around the four corners area of the Southwest, and includes much of Arizona, Utah, Colorado, and New Mexico, is a large and important component of U.S. drylands. This important home to mountains, desert basins, dramatic canyons, arid woodlands, and grasslands is also one of North America’s most rapidly warming hot spots, with rates of warming of up to 2-3° C within...

Don't Bust the Crust
To examine the influence of biological soil crusts in ecosystems (soil food webs, soil stability, soil nutrient cycles, and plant communities), Hilda Smith, biological technician, prepares to resample paired experimental plots where biological soil crusts were removed annually since 1995 or left intact at Arches NP.

Experimenting with Climate Change
Hilda Smith, biological technician with Canyonlands Research Station, monitors changes in biological soil crusts in response to experimental increases in temperature and altered precipitation patterns.

Factory Butte
A variety of sampling methods are used to assess the movement of dust at different heights at Factory Butte. Dust samplers in the foreground are part of an ever-increasing network of more than 140 sites.

Silt Fences Await Sediment from Storm Runoff
Silt fences were installed at paired locations on Mancos Shale to quantify sediment in runoff in disturbed and undisturbed areas.

Canyonlands and the Colorado Plateau
The Needles district of Canyonlands serves as a stunning backdrop to our study site in the high desert grassland of the Colorado Plateau. Researchers at Canyonlands Research Station are testing the effect of experimentally imposed altered precipitation regimes on plant reproductive success, mortality, and biomass.
