Serpentine Barrens

Serpentine Barrens are rare and unique ecoregions that can be found globally, in small pockets of land with serpentine bedrock and soil. The term "serpentine barren" generally refers to a serpentine outcrop and its distinct associated vegetation. Vegetative communities growing in serpentine barrens differ from surrounding areas by having a notably distinct physiognomy and community structure, low species richness, a dominance of specific taxa, a predominance of xerophytic species, low productivity, the co-existence of high and low ph-tolerant species, and high rates of endemism. [ ] This difference in vegetative communities is driven by the toxic mineral composition of the serpentine bedrock that has weathered into the soil.
