Add to ORKGA plant cover map of the land comprising the five thousand acre watershed of Lake Wapello has been made in connection with erosion control, lake silting and game management problems confronting the Iowa Fish and Game Commission in the development of this southern Iowa fishing lake. The extent of various cover types with the important species composing each type and the per-of soil erosion areas on the map permits the correlation of extent of erosion with plant cover. The locations of the pictures presented has been recorded so that successional changes in vegetation may be traced
