The second year of five on this study has been completed. The plant communitites in the area have been mapped and various subdivisions of these have been made partly as a result of their stage of ecological development in this geologically young area, and partly on the basis of their disclimax development as a result of grazing pressures. This project is closely tied to Project 89-- "An evalualtion of certain exclosures" by Dixie Smith. Joel Verner worked throughout the summer on phases of this project. Project Number 85.
