Climax Conditions and the Ecological Status of Pinus Strobus, Taxus Canadensis and Tsuga Canadensis in the Pine Hills Region of Indiana

摘要

Along Sugar creek in Montgomery and Parke counties in west central Indiana, where the stream cuts through the Mansfield and deep into the Borden sandstones, there are a number of areas characterized by deep canyons with almost perpendicular rock walls. Three of these areas are locally known as Turkey Run State Park, The Shades, and Pine Hill~. The latter two are about two mile~ from each other, and these in t.urn are approximately eighteen and twenty miles respectively upstream from Turkey Run. The canyon walls of Turkey Run are largely Mansfield sandstone, while those of Pine Hills are Borden sandstone, the Mansfield having been eroded away.
