Symphyotrichum depauperatum, also known as the Serpentine aster, is a rare species of aster adapted to serpentine barrens, an ecosystem with a high concentration of toxic metals in the soil.
Distribution
It occurs in 20 of the 26 serpentine barrens in the eastern United States, and has been called a "flagship" species of this unique ecosystem. It was previously thought to be endemic to these barrens, but it was recently confirmed to also occur in a disjoint population on diabase glades in North Carolina.[2]
Conservation
Symphyotrichum depauperatum is classified by the state of Pennsylvania as a threatened species because its range is restricted to a few limited areas, and the majority of its populations occur on sites threatened by quarrying, housing and industrial development.[3]
