6. Vegetation Installation and Management Timeline <br />6.1. Site Prep and Installation Phase <br />Site Preparation: <br />1. Prior to the start of construction, a cover crop may be seeded to aid in erosion <br />control, soil moisture management, and weed suppression. <br />2. Inspection of the project area to assess site conditions and determine the need for <br />any site prep mowing or spraying activities. <br />3. If necessary, an herbicide application will be completed using glyphosate (Round- <br />up° or equivalent) as per manufacturer's directions in areas with actively growing <br />vegetation. Allow a minimum of 14 days before disturbing the soil or completing <br />seeding activities. <br />4. When perennial broadleaf vegetation is present a triclopyr herbicide will be added <br />(Garton 3A° or equivalent) as per manufacturer's directions. When a broadleaf <br />herbicide is used allow a minimum of 30 days before disturbing the site or <br />completing seeding. <br />5. Depending on the density and type of undesirable vegetation present (i.e., annual <br />vs perennial) a complete site mowing might be advisable in lieu of an herbicide <br />application. For instance, if the site is dominated by Foxtail (an annual), mowing <br />would be preferrable to an herbicide application. <br />Soil Prep and Seeding: <br />1. Construction debris, garbage, and building materials will be removed and/or <br />staged outside the intended seeding areas. <br />2. Disk soil within the project area in preparation for seeding. Harrow or rake the soil <br />to achieve the proper seedbed. <br />3. Broadcast the large and fluffy seed (mostly grasses) along with a cover crop of <br />winter wheat or oats. <br />4. Harrow or rake the soil to work the seed to a proper depth. <br />5. Broadcast the small seeds (forbs, sedges, rushes, small grass seeds) on top of the <br />soil. <br />Installation Phase Maintenance <br />If the site is seeded in the summer or early fall, 1-2 complete site mowings may be needed <br />during this first partial growing season. <br />6.2. Establishment Phase <br />atNatural <br />Resource <br />Services <br />Year 1 is defined as the 1st full growing season for the vegetation. A recommendation of 3 <br />complete site mowings is most common for this phase. Depending on site conditions and <br />vegetation growth, more or less may be needed. <br />10 <br />
