Abstract
In the region of Turkey Run State Park, Parke county, Indiana, there occurs an abundance of Hemlock, Tsuga canadensis. In this locality the tree is to be found typically along the upper limits of precipitous creek bluffs and along the rims of the sandstone canyons,-- here it is the dominant plant in an edaphic climax. The Hemlock association is a codominant climax with the typical Beech-Maple climax of the region.
