would be intercepted by continuing to project the needle downward after the first interception is recorded, these interceptions will be recorded separately. Herbaceous vegetation production will be measured at a minimum of 5 random points alongg each randomly located cover transect. Herbaceous productivity by lifeform will be measured by clipping all current-year herbaceous material to ground level and categorizing and bagging each life form separately. Clipping will be done on meter square quadrats in the upland type, however, due to the homogeneity of productivity in the river terrace type I/2 meter square quadrats will be be used, All clipped material will be oven dried and weighed to the nearest O.lg. Total herbaceous vegetative production (g/m2 and lbs./ha) will be calculated for all life forms encountered, summarized and presented in the final report. As mentioned previously, since a woody stem density will not he set, shrub density data will not be collected. SUCCESS CRITERIA The reclamation success standards developed by Western Slope Carbon, Inc.,which include cover, productivity, woody plant density where applicable and diversity will be used to evacuate revegetation success on the reclaimed area. Each revegetation zone will be compared against the success standard from the comparison area which best represents the potential for that area(see attached map for a complete delineation of these areas). Sampling procedures used in sampling the revegetated zones will be similar to that used in sampling the comparison areas. Sampling adequacy will be based on WDEQ Guideline No. 2. Herbaceous cover and productivity of revegetated areas will be considered acceptable if said cover and productivity are at least 90 percent of cover and productivity of the success standard. The success standard for cover on the upland oakbrush revegetion zone uill be the total perennial cover on the comparison area. This allows fora conversion of an oakbrush type to a grassland type while still maintaining a sufficient cover for erosion control. The herbaceous cover in the river terrace area is dense enough for a direct comparison with herbaceous vegetation on river terrace revegetation zones. Western Slope Carbon, Inc. plans to meet revegetation success criteria by seeding or planting all disturbed areas to achieve a permanent vegetative cover of the same seasonal variety native to the area. Western Slope Carbon, Inc. wil develop a diversity standard from the data collected on the comparison areas and submit it to the CMLRD for approval. The shrub density standard on the riparian area where shrubs will be transplanted will he 500 stems/acre. No shrub density standard will be developed for other revegetation areas. Assuming acceptable species composition after revegetation, reclamation will be determined successful when the productivity ,cover and density, if applicable on the reclaimed site is similar to the reclamation
