<br />Wetland Seeding Plan <br /> <br />The following seeding plan utilizes elements and recommendations from the Seeding <br />lv/anua! of MnDOT Office of Environmental Services, Turf Establishment and Erosion <br />Control Unit, Draft Year 2000. <br /> <br />Preparation and Seeding <br /> <br />1. The smooth~graded wetland areas designated for seeding should be prepared by <br />loosening topsoil to a minimum depth of 3 inches. <br /> <br />2. Seeding should be conducted either Apri115-July 20 or Sept. 20-0ctober 20. <br />Seeding can be accomplished by broadcast or drilling. Broadcast seeding is <br />particularly recoffirn.ended for the wethmd seed mixture unless the weather is hot <br />and dry and/or the soil moisture content is low at the time of seeding. Broadcast <br />seeding should by a~complished by use of any type of broadcast seeder capable of <br />broadcasting the seed evenly over the entire area. Seed should be mixed <br />thoroughly prior to seeding and should be mixed occasionally in the spreader to <br />prevent separation and settling. If the drill seeding method is used, seed should be <br />installed with Ii Truax-type seed drill c.ontaioing a minimum of2 seed boxes (fine <br />seed box & box for large/fluffy seeds) and equipped with disc furrow openers and <br />packer assembly to compact the soil directly over the drill rows. Maximum row <br />spacing should be 8 inches. Small and fine seeds should be drop-seeded onto the <br />surface from the fine seed box, and large/fluffY seed should be placed to obtain a <br />final planting.depth of ~~~ inches. All drill seeding ,should be done at a right <br />angle to surface drainage. Recommended seeding rates are given for wetland <br />seed mixture at the end of this plan. <br /> <br />3. The seeded areas should be harrowed or raked following seeding. The areas <br />should then be packed using a cultipacker or equivalent. Packing will be <br />considered adequate when only Ii slight footprint is left in the soil after walking <br />across the area. <br /> <br />4. Following packing, the areas should be mulched and disc-anchored at a rate of2 <br />tons/acre using MetA certified weed free mutch, MnDOT Type 7 or 8 prairie <br />hay/mulch, or MoDOT Type I clean straw mulch. <br /> <br />Maintenance and Evaluation of Seeding Success <br /> <br />Year 1 (spring seeding) <br /> <br />· Prepare and seed site April IS-July 20 <br />· Mow to a height of6-1O inches July 20-August 20 <br />· Optional moWing in early September <br />· Spot spray weedy species such as thistles <br />
