5.3.3 Definition of Success <br /> The mitigation project goal will be deemed successful when objectives are met, as evidenced <br /> through the observation of set performance standards. <br /> 5.3.4 Objectives <br /> Objective 1: To establish a diverse, native plant community in the wetland buffer that will persist <br /> and create an appropriate vegetative matrix. <br /> Objective 2: To have significant native vegetative cover throughout the restoration area. <br /> Objective 3: To remove existing invasive species and limit the establishment and spread of those <br /> species in the buffer. <br /> 5.3.5 Performance standards <br /> Year 1 Monitoring <br /> Performance Standard: 100 percent survival of planted species <br /> No greater than 20 percent coverage of invasive species <br /> Year 3 Monitoring <br /> Performance Standard: 80 percent survival of planted species <br /> No greater than 20 percent coverage of invasive species <br /> New growth shall be observable and documented <br /> Year 5 Monitoring <br /> Performance Standard: 80 percent survival of planted species <br /> No greater than 10 percent coverage of invasive species <br /> New growth shall be observable and documented <br /> 5.4 MAINTENANCE <br /> This mitigation project will require periodic maintenance to replace mortality of the planted trees <br /> and shrubs. Maintenance is also necessary to control invasive, non-native plant species and <br /> competing grasses. The planting areas will be maintained in the spring of each year for the five- <br /> year monitoring period. Maintenance will include hand removal of competing grasses and non- <br /> native vegetation from a 2-foot diameter ring surrounding a given plant. Removal of invasive <br /> species shall be done by hand to decrease the likelihood of damage occurring to the plantings. All <br /> blackberry, reed canarygrass, and other aggressive invasive species sprouting anywhere within <br /> the mitigation site shall be removed during each maintenance period. Herbicide use is <br /> prohibited. <br /> When necessary, mulch shall be replaced around each plant. Each plant shall receive a 2-foot <br /> diameter ring of mulch to a height of 3 to 4 inches above the existing soil surface. A 4-inch <br /> diameter ring around the base of each plant shall be kept free of mulch. Wood chips or <br /> composted mulch is acceptable. <br /> Mundorf-8th St 21 Critical Area Study & <br /> WRI#16233 Mitigation Plan <br /> March 2016 <br />
