Vegetation Monitoring <br /> Sampling points or transects will be established for vegetation monitoring and photo points will be <br /> established from which photos will be taken throughout the monitoring period. Permanent <br /> sampling points must be identified on the mitigation site plans in the first monitoring report (they <br /> may be drawn on approved enhancement plans by hand). Each sampling point shall detail shrub <br /> and tree coverage. Monitoring of vegetation sampling points shall occur annually between May 15 <br /> and September 30 (prior to leaf drop), unless otherwise specified. <br /> Photo points <br /> At least two permanent photo points will be established within the enhancement area. Photographs <br /> will be taken from photo points to visually record condition of the enhancement area. Photos shall <br /> be taken annually between May 15 and September 30 (prior to leaf drop), unless otherwise <br /> specified. <br /> Monitoring Reports <br /> Monitoring reports shall be submitted in the fall of each year during the monitoring period. As <br /> applicable, monitoring reports must include descriptions / data for: <br /> 1) Site plan and vicinity map; <br /> 2) Historic description of project, including date of installation, current year of <br /> monitoring, restatement of mitigation / restoration goals, and performance standards; <br /> 3) Plant survival, vigor, and areal coverage (transect or sampling point data), and <br /> explanation of monitoring methodology in the context of assessing performance <br /> standards; <br /> 4) Assessment of nuisance / exotic biota and recommendations for management; <br /> 5) Color photographs taken from permanent photo-points that shall be depicted on the <br /> monitoring report map. <br /> 5.8.3 PROJECT SUCCESS AND COMPLIANCE <br /> Performance Standards <br /> The enhancement area must achieve the following Performance Standards to be considered <br /> successful: <br /> Year 1 Year 3 Year 5 <br /> Survivorship* 100% 80% 60% <br /> Native plant cover** 30% 40% 50% <br /> Invasive species cover <10% <10% <10% <br /> *Only applies to installed native plantings. <br /> **Native existing and volunteer species may be included to meet native species cover requirements. <br /> 5.9 MAINTENANCE PROGRAM <br /> The restoration area will require periodic maintenance to remove undesirable species and replace <br /> vegetation mortality. Maintenance may include, but will not be limited to, removal of non-native <br /> 2127100th Street SE 18 WRI#23188 <br /> Critical Area Study and Mitigation Plan October 9, 2023 <br />
