Footprint damage to biocrusts
Many human activities can be unintentionally harmful to biological crusts. The biocrusts are no match for the compressional stress caused by footprints of livestock or people or tracks from vehicles.

Biocrust
On the Colorado Plateau, mature biocrusts are bumpy and dark-colored due to the presence of lichens, mosses, and high densities of cyanobacteria and other organisms. Disturbed biocrusts are lighter in color, looking more like the underlying sand than undisturbed ones, and are less capable of stabilizing soils or providing soil fertility.

Dark-colored mature biocrust
On the Colorado Plateau, mature biocrusts are bumpy and dark-colored due to the presence of lichens, mosses, and high densities of cyanobacteria and other organisms. These organisms perform critical functions, such as fertilizing soils and increasing soil stability, therefore reducing dust.

Biocrusts provide soil stability and prevent erosion
Biocrusts provide soil stability and prevent erosion. Soil is the foundation where plants live; if soil is not stable, native plants can have difficulty growing.

Nonnative tamarisk is fire resistant
Nonnative tamarisk is resistant to wildfire, in part due to its abilty to resprout from the its roots.
