White-topped aster occurs in open grasslands, including seasonally-wet prairies and oak savannah.
Limiting factors
Primary threats to white-topped aster include habitat loss and habitat degradation due to lack of fire and competition from invasive plants. Overspray of herbicides may also harm this species.
Data gaps
Conduct pollinator studies. Develop a seed-sowing protocol.
Conservation actions
Maintain or restore grass-dominated habitat. Control key invasive plants. Use mowing or prescribed fire to control brush and trees. Maintain populations in roadsides and ditches. Collect and store seeds.
