their initiation. It maybe necessary to control weeds by mowing after the first year; the feasibility of chemical weed control methods will be studied should it be necessary. The plan does not con- template total weed removal on the property. Past experience shows that some initial weed cover in the first yeaz following retopsoiling is beneficial to the reclamation effort. Weeds tend to pro- vide shade for new grasses, are a means of holding snow on the seedbed longer and protect it from wind and water erosion until the planted species have taken hold. 4. Revegetation Success Criteria Dryland Areas It is suggested that revegetation in the wetland area should be deemed successful when the peren- nial vegetation is self-sustaining and adequate to control erosion. The dryland areas will be deemed adequate when the live perennial cover reaches 90% of its pre-mine level of approximately 30%. Wetland Areas To be deemed successful, the cover must equal the pre-mine level. Since considerable new wetlands will be created, this should not be difficult to achieve. The wetland areas should be deemed successful when the following has been accomplished: 1) At least 3 of the planted species are present and visible in the wetland azeas,.and 2) At least 75% of the willow clumps designated in the plan are present and viable, and 3) Wetland live perennial cover is at least 80% of what is expected for this set of conditions in the surrounding azea, and 4) The vegetation must be dominated (greater than 50% relative cover) by wetland species and 5) No noxious weed infestations shall be present in the wetland areas. The revegetated areas will be monitored for success of reclamation until accepted by the Division. If revegetation failures occur prior to release, an analysis of the site will be made and the azea will be revegetated again as necessary. North Fork Pit March 04 35
