7.0 MAINTENANCE, MONITORING, AND CL%N nNGENCY 7.1 MAINTENANCE ACTIVITIES The purpose of this maintenance program is to ensure the success of the mitigation plantings. The planting areas will be maintained in the spring and fall of each year for the three-year monitoring period. Maintenance activities will include the following as necessary: • Plant inspection and replacement • Limited Control invasive species • Remove trash Following each monitoring, recommendations will be made for the replacement of plant mortality. Any replanting will be done by the contracted landscap• � and should be done during the fall maintenance visit. Maintenance should be done by hand to avoid impacts to establishing plants and existing habitat. 7.2 INVASIVE SPECIES Weed control will be accomplished through the use of hand removal and mowing. Himalayan blackberry is the main species of concern for this mitigation project. All Himalayan blackberry within five feet of the plantings shall be removed above ground by hand only. No disturbance to the surface soils is permissible. If it is determined by the Geotechnical Engineers that the soils are impacted by invasive species cortlol, the method of maintenance will be discontinued. The goal of this maintenance is to allow the planted native species to establish. At that point, it is expected that shading will prevent further establishment of invasive species. 7.3 PERFORMANCE STANDARDS Performance standards have been established to assess the success of the mitigation project in achieving the stated goals. Performance standards are as follows: 7.3.1 PLANT SURVIVAL Year 1 Monitoring Success Standard: 90 percent survival of planted species Year 2 Monitoring Success Standard: 80 percent survival of planted species Year 3 Monitoring Success Standard: Minimum 50 percent aerial coverage of native species Wet land Resources, Inc. 9 Anderson SFR - Restoration Plan WRI # 09126
