Distribution and habitat

Symphyotrichum estesii is found only in the May Prairie State Natural Area of Coffee County, Tennessee, within an area of less than 5 hectares (less than approximately 12 acres).[2] May Prairie is located in the Eastern Highland Rim of central Tennessee.

Within May Prairie is an open grassland little bluestem community and a tallgrass prairie community, as well as some sedge meadows. The combined grassland community is surrounded by an oak forest that begins the oak barrens.[4] The Symphyotrichum estesii population thrives in the hydroxeric soils in the open and sunny flat prairie sites. In semi-shaded areas nearer the woods, it can rarely be found.[2]

Conservation

NatureServe lists it as Critically Imperiled (G1) worldwide.[1]
