Date: 1/22/2007 An outline of the suggested materials and procedures to be used to establish a native buffer and enhance the wetland at the Lund Residence in Orono, MN Buffer size: approximately 18,000 square feet, averaging SO feet in width Wetland Enhancement Area size: approximately 10,000 square feet A. Project Objectives: 1. Establish a native buffer to protect the existing wetland and create an attractive, naturalistic transition between the traditionally landscaped azeas and the wetland. This buffer will consist primarily of native grasses and wildflowers with native tree and shrub plantings in key azeas. The buffer will average 50 feet in width,with some narrower areas to a11ow shore access. The width will be expanded in other areas to compensa.te for the narrower portions. 2. Enhance portions of the existing wetland by removing the invasive stands of reed canary grass and reseeding and planting with desirable native species. This will improve the diversity, wildlife value, and aesthetics of the wetland. It will also protect the buffer seeding from reed canazy invasion. B. Site Preparation: 1. In areas with actively growing vegetation apply Rodeo�herbicide(or equivalent wetland approved glyphosate formulation)and Garlon 3A�herbicide as per manufacturer's directions. Allow a minimum of 30 days before disturbing the vegetation with other procedures. 2. Conduct a controlled burn using proper pernuts and procedures or mow the site to remove dead vegetation. 3. Rototill the soil to create an open seedbed and stimulate weed seed germination. The Wetland enhancement area will not be tilled. 4. Respray with Rodeo�herbicide when regrowth of vegetation occurs and when it reaches approximately 4" to 6" in height.Allow a minimum of 15 days before disturbing the vegetation with other procedures. 5. Harrow or rake the soil to create a firm, smooth seedbed.
