The Vascular Flora and Vegetational Communities of Cabin Creek Raised Bog, Randolph County, Indiana

ABSTRACT From 2004 to 2012 a study of the flora and floral communities at Cabin Creek Raised Bog (Cabin Creek) was conducted. Cabin Creek, designated a National Natural Landmark by the National Park Service in December, 1974, is privately owned. It is located in west-central Randolph County, Indiana. An inventory of the vascular flora revealed 478 taxa representing 282 genera and 91 families. The 12 families containing approximately 62% of the documented species (in order by number of species) were Asteraceae, Cyperaceae, Poaceae, Rosaceae, Liliaceae, Lamiaceae, Scrophulariaceae, Apiaceae, Fabaceae, Ranunculaceae, Brassicaceae, and Polygonaceae. Of the 478 documented species, 400 were native, 78 were exotics, and 118 represented new Randolph County records. There were three species with Indiana Rare-Threatened-Endangered status, including Veratrum virginicum (endangered), Triantha glutinosa (rare), and Melica nitens (threatened). A physiognomic analysis (i.e., summary of plant form or habit) is presented....
