Erika Geiger, Ph.D.
Erika Geiger is a Supervisory Biologist and Director of Operations with the Southwest Biological Science Center, based at the Canyonlands Research Station (CRS) in Moab, UT.
Erika 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 stationed at the Southwest Biological Science Center's Canyonlands Research Station in Moab, Utah.

Riparian vegetation, topography, and ground cover constituents along the Upper Colorado River near Moab, UT (2010-2017) (ver. 1.1, Jan 2023) Riparian vegetation, topography, and ground cover constituents along the Upper Colorado River near Moab, UT (2010-2017) (ver. 1.1, Jan 2023)
The data release presents observations of riparian vegetation, topography, and ground cover in two river reaches of the Upper Colorado River within a river segment extending 208 river kilometers (rkm), from near the Colorado/Utah border to the confluence of the Green River. Methods included field observations and analysis of the plant community five times over eight years in the fall of...
Meteorological measurements from five locations within the Badger Wash study area near Mack, Colorado (ver. 3.0, September 2024) Meteorological measurements from five locations within the Badger Wash study area near Mack, Colorado (ver. 3.0, September 2024)
These data are records collected from an automated weather station and four stand-alone tipping bucket rain gauges each with their own data logger that were in operation between February 2005 and December 2019 in the Badger Wash Study Area near Mack, Colorado as part of a larger project funded by the Bureau of Land Management. These files are hourly-interval data from the automated...
Long-term precipitation reduction experiment in the Colorado Plateau - Survival and mortality data from 2010 to 2018 Long-term precipitation reduction experiment in the Colorado Plateau - Survival and mortality data from 2010 to 2018
From 2011-2018 USGS biologists recorded vegetation and biological soil crust (BSC) cover by species and tracked survival of tagged individual plants (388 in total) across 40 locations where paired experimental plots had been installed in 2010. Plant cover was visually estimated using four 75 x 100 cm survey frames. Each site contained a two plots measuring 1.5 by 2.0 meteres: a control...
Vegetation and Soils Data from Grazed and Ungrazed Watersheds in the Badger Wash Study Area, Colorado, USA Vegetation and Soils Data from Grazed and Ungrazed Watersheds in the Badger Wash Study Area, Colorado, USA
In 2004 U.S. Geological Survey biologists recorded vegetation and biological soil crust (BSC) cover by species as well as measured soil stability and compaction data along 85 transects at the Badger Wash study area in western Colorado. Soil samples were collected and processed for chemistry and texture. Using analysis of variance and nonmetric multidimensional scaling (NMDS) we assessed...
