Maintenance Methods <br />Bluff Area <br />In the Bluff buffer area the buffer area will initially have buffer mon umentation placed ipproxi:maAtcly <br />every 200 feet along buffer edges. <br />Area B <br />In buffer area B the buffer ;area will initially have buffer monumenta.tion placed approximately every 200 <br />feet along buffer edges. <br />Area C <br />In buffer area C the buffer area will initially have buffer monumenta.tion placed approximately every 200 <br />feet along buffer edges. <br />Next year vegetative management will ocei.ir with spot spraying and weed whipping of areas, followed by <br />Escort or Glysophosphate application to weed areas needing control. Seed will be spread if necessary per <br />the below seed specifications if needed. <br />V. Seeding Specifications if Planted: <br />a. Timing of Seeding: Due to the small size of most buffer seed varieties, all seed will be broadcast. <br />To maximize success, the planting of seed can only occur within tw,o small windows„ April 1 to <br />June 30 or September 1 to December 1. <br />b. Seed Mix and Installation Specifications*: The grassy buffer maintained areas will be sc!eded <br />with Mix 35-541 at 12.0 pounds of pure live seed per acre. Cover crops specified for each mix will <br />be seeded with each mix_ in accordance with BWSR_ mix specifications. The Appendix contains the <br />specifications for the seed mixes specified. Below is a table and surn:mary of seed mixes. <br />Seed Mix <br />Trate Est. Total Amt. <br />(11b,/ac.)_ Seed Used (lbs.) <br />Mesic Prairie Southwest Seed Mix <br />12.0 TBD <br />*Note: See "Guidelines for Restoring and Managing Native Wetland Vegetation"for seed mix <br />percentages and specifications for seed density on a. square foot basis. <br />c. Site Preparation and Seeding Technique: 'The upland buffer areas will be dra;ged after the seed <br />is broadcast as needed to achieve proper seed to soil contact. Straw mulch will be applied at 1.5 <br />tons per acre and disk anchored where possible. On any slopes in the buffer area exceeding a 10 <br />percent slope, straw erosion blanket will be installed after seeding. <br />VI. Prevention of Introduction of Invasive Species: It is important that any topsoil that is pll aced on <br />the site be free of any rhizomes and seed from vegetation that is unciesira,ble in a buffer. Therefore it is <br />imperative that the coordination between the grading contractor .and the environmental consultant is <br />
