<br />The sparse browse and "landslides" mentioned earlier show on the left <br />side of the drawing. <br />During the time the face of the disposal pile is moving, Occidental plans <br />to administer two interrelated programs. The first is to gather meteoro- <br />logical data to assist in determining the microclimate at the site of <br />the pile. The second is plant experiments designed to provide data on <br />grass, forb, and shrub species which can adapt to the microclimate of <br />the pile area and the soil conditions that will exist in the pile. <br />A small plant experimental area has been selected and fenced. It is <br />expected that seeding of selected grasses will begin in the Spring of <br />1976. As more bench is built up, additional plant experiments will be <br />established. These additional experiments will include seeding and <br />• transplanting selected species of grasses, fortis, and shrubs to select <br />optimal seeding rate or transplanting to obtain best results. Rate and <br />amount of irrigation required to provide minimal establishment will also <br />be studied. Experiments may need to be conducted over the life of pile <br />construction. Since the natural talus slopes of the region support no <br />more than a very sparse natural vegetation established over a long period <br />the vegetation established on the pile can be expected to be sparse also <br />to blend with the natural surroundings. <br />Peregrine Falcons <br />OXY engaged Dr. Wm. 0.
