Tree and Shrub Plantings (Riparian and Upland). The tree and shrub plantings are primarily for screening purposes;therefore,there are no-net-loss objectives. Native tree and shrub plantings will improve wildlife habitat and aesthebasedic values. Therefore,on maintenance of the rrformance screening criteria for the tree and shrub plantings shall beased function. Each tree and shrub shall be evaluated annually for general health. For the measure to be considered successful, at least 50 percent of the plantings should be considered healthy and capable of growing without irrigation within 5 years. The drip-irrigation system will be checked for malfunctions and necessary adjustments shall be recommended. After 2 years, the biological monitor shall make a recommendation as to whether the irrigation system should be removed. Hydrologic Monitoring Wetland hydrology shall be monitored when the grading for the vernal pools,wetland swales, and marshes have been completed and there has been sufficient precipitation to fill the existing wetlands onsite. Water depths shall be measured twice each wet season in all created, protected, and selected unprotected vernal pools, swales, and marshes after the wetland hydrology has been determined. The depth measurements shall be taken from those sites selected for vegetation monitoring as identified above. The approximate duration of ponding and soil saturation shall be recorded for the same sites. Water depths and undisturbed wetlands periods of saturation in the created wetlands shall be compared to determine if hydrology in the created wetlands is similar to that of the undisturbed wetlands. Monitoring Schedule The monitoring schedule is designed to assist the biological monitor in implementing the monitoring program. The schedule is divided into tasks that address specific goals of the program, including collecting baseline data to establish performance criteria, monitoring wetland creation and revegetation efforts, and preparing the annual monitoring report. A suggested time frame for accomplishing the monitoring tasks is shown in Table 10. Reporting Results The results of the monitoring program shall be summarized in annual reports for a period of 5 years. Each annual report shall describe and interpret the results of the previous year's monitoring;include representative photographs of each sample site; evaluate the success to date of mitigation measures relative to mitigation performance standards; 56
