Serpentine Barrens are unique ecoregions that can be found globally, in patchy/small pockets of land with serpentine bedrock and soil. The term "serpentine barren" generally refers to a serpentine outcrop and its associated vegetation. These habitats are notable for their distinct vegetation with high rates of endemism. The difference in vegetative communities is the product of chemical, physical, and biotic edaphic factors but is primarily driven by the toxic chemical composition of the serpentine bedrock and soil. These systems are used to study edaphic endemism and plant speciation. [ ] They are also used as an analog to brownfields in restoration ecology because of the high heavy metal content in the soil.
