A Natural History Study of the Vascular Flora of Cedar Bog, Champaign County, Ohio

Abstract

Cedar Bog Nature Preserve is a relict boreal bog situated in the Mad River valley in Champaign County, west-central Ohio. Originating following the retreat of the Wisconsin glacier, it has been maintained by the combination of a usually cool moist microclimate and a uniform flow of cool ground water. Microclimatic data recorded from 1963 through 1969 demonstrate that Cedar Bog has cooler temperatures and a shorter frostfree period than do adjoining areas. These two factors have resulted in the survival of plants unique to this part of Ohio.
