,~ lementation This area was seeded and raked in October of 1980. The seed mix was: 5 ep cies Rate in lbs/acre Western Wheatgrass 8 Slender Wheatgrass 8 Streambank Wheatgrass 2 Sherman Big Bluegrass 4 Canada Bluegrass 4 Indian Ricegrass 2 Rocky Mountain Penstemon 1/4 Palmer Penstemon 1/4 Blue Flax 1/4 Golden Banner 1/4 Globemallow 1/4 Fireweed 1/4 Sulfur Eriogonum 1/4 The mulch materials which were applied include excelsior, Jacklin organic mulch, hold~ro, jute netting, and 2 T/A straw covered with Cm wed netting. Details m methods and time required for application will be included in the section on Northern U1 mulch. Management Spring fertilization with 120 lbs/.acre (30-10-OJ should be continued for the next 2 to 3 years. Results The purposes of a mulch are twofold: (1J to stabilize the soil or stop erosion and (2J to enhance plant establishment by providing shade for seedlings, thereby keeping soil temperatures cooler and conserving moisture. Thus, the mulches used in this study will be rated m both of these parameters. Visits to the mine site in late April and early June provided data on these mulches with respect to their potential to stop erosion. And the June visit provided an early indication as to the mulch's ability to enhance plant establishment. However, data from this fall and subsequent years will be necessary for the complete picture. Photographs 20 and 21 show the Jacklin organic mulch and Hold~ro, respectively. Both of these products were very poor at controlling erosion and did little to enhance seedling establish- ment. Photograph 22 is jute netting which appears to be very successful in both erosion control and seedling establishment. In Photograph 23 straw and Cm wed netting is m the left and excelsior is m the right. The Cm wed and straw is doing a slightly better
