Newcomers to a state are often baffled and confused by the use of obscure terminology to describe local physiographic regions. When I first moved to Kentucky, references to the vegetation of the Knobs region made little sense to me because I could not find the Knobs region on a map. For newcomers and longtime residents alike, who have always wanted a concise description of Kentucky native vegetation placed in the context of physiography, this publication will be a handy and useful reference.
