摘要

Lakeside daisy (Hymenoxys herbacea (E.L. Greene) Cusick = H. acaulis var. glabra)is a federally threatened (listed in 1988) and Ohio endangered species (listed in 1980). It occurs naturally only in Ohio and Ontario and has been restored at three sites in Illinois. In Ohio, the species is restricted to the Marblehead peninsula adjacent to Lake Erie in Ottawa County. The plant formerly grew in the dry, limestone prairies of Marblehead, but these areas have been destroyed by limestone quarrying. The species has survived despite the quarry activities and now thrives in abandoned areas of the active Lafarge Marblehead Quarry. Although the number of plants on Marblehead Peninsula is large (more than one million adults, scattered across three square miles, DeMauro 1993), only a small portion of them are protected. In 1988, the Ohio Department of Natural Resources, Division of Natural Areas and Preserves, acquired a 19-acre tract of abandoned quarry land which was dedicated as the Lakeside Daisy State Nature Preserve in 1989.
