Monitoring Reports: Annual monitoringreports will be completed for the first three ears following P P Y 9 restoration/enhancement activities (i.e., 2015 through 217). Reports will follow the MN Board of Water and Soil Resources'"Replacement Wetland Annual Monitoring Report"format. Performance Standards: Performance standard to be applied to the wetland follow: 1) The combined cover of invasive cattail, purple loosestrife, and reed canary grass shall not exceed 20%total cover at any time during the 2015-2017 short-term management period. 2) By the end of the second year of management(end of 2016) and through the end of the short- term management period (end of 2017),total vegetation cover shall be no less than 80%, not including open water areas. 3) Just prior to the end of the short-term management period (end of 2017), restored Wet Meadow areas shall contain a minimum of: 30%cover by native grass/sedge species, 20%cover by native forb species, and 33%of installed species present. Deep Marsh areas shall contain at least 6 planted species widely dispersed throughout the planted areas. Other Enclosures with this Submittal 1. Restoration Plan Set 2. Certificate of Survey 3.
