NatureServe Status

Global Status: G5
Global Status Last Reviewed: 23Sep2002
Global Status Last Changed: 20Jun2002
Rounded Global Status: G5 - Secure
Reasons: Widespread: occurs in the eastern three-fourths of United States, and from Alberta to Quebec in Canada. Sporobolus heterolepis is a prairie species with spotty distribution in the eastern part of its range, where it is sometimes found on serpentine, limestone, or other unusual rocky substrates. It has a stronghold in the central United States but becomes rare in the eastern portion of its range.

NatureServe Global Conservation Status Factors

Range Extent Comments: From Saskatchewan to Quebec south to Sonora, Oklahoma, Arkansas, Kentucky, and Georgia (Kartesz 1999).

Overall Threat Impact Comments: Highly threatened by succession, and to a lesser extent by land-use conversion, habitat fragmentation, and forest management practices (Southern Appalachian Species Viability Project 2002). In Michigan, this species may be threatened by alterations to hydrology and woody encroahment due to fire supression (Higman and Penskar 1999). In Ohio, this species is threatened by farming of prairies (McCance and Burns 1984). It is also somewhat sensitive to grazers.
