NatureServe Conservation Status
Rounded Global Status Rank: G5 - Secure
Reasons: Although this species remains very common in parts of its range, it appears to be in severe decline in others. Habitat destruction and manipulation has caused a range wide decline of this species. The general center of this species distribution (the eastern tallgrass prairie states) has been almost entirely converted to agricultural and urban uses. Fragmentation of remaining habitat, contamination of the gene pool, and wild harvesting present ongoing threats to this species. Nevertheless, it is still quite common in semi-natural settings such as roadsides and old fields.
