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.

USGS scientists created outdoor testing plots where large squares of biocrusts were exposed to different warming and precipitation factors over time.

Tamarisk leaves regrow following defoliation by the biological control agent, tamarisk leaf beetle (Diorhabda spp.).
Tamarisk leaves regrow following defoliation by the biological control agent, tamarisk leaf beetle (Diorhabda spp.).
Nonnative tamarisk can form mixed stands with native trees, such as cottonwoods, and other nonnative trees, such as Russian olive.

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