<br />4 <br />Due to the openness that defines oak savannas, the grasses and other herbaceous vegetation <br />are a critical component to a successful site. Open areas will be planted utilizing the Woodland <br />Edge South & West seed mix (Appendix A) at the minimum rates prescribed. <br /> <br />5. Site Preparation / Initial Work <br />The following initial work should be considered for all site preparation work: <br />1. Delineate tree planting areas: <br />a. For Floodplain Forest, tree and shrub planting areas need to cover at least 80 <br />percent of total area. The remaining 20 percent of the mitigation area would be <br />seeded with native forbs and grasses germinated from locally grown propagules. <br />These areas of local vegetation would be interspersed between the tree planting <br />areas. <br />b. For Oak Savannah, tree planting areas should be in clusters to cover between 10 <br />and 50 percent of total site area. The remaining area would be seeded with the <br />Woodland Edge South & West seed mix. <br />2. Clear and grub the identified tree planting area and properly dispose of significant woody <br />debris if necessary. <br />3. Treat the site with glyphosate after spring green-up and again in early fall to clear the <br />site of any competing vegetation. <br />4. If soil prep is needed, disc the site to expose mineral soil and treat with an approved pre- <br />emergent herbicide if discing in the spring. If a fallow period is expected, incorporation <br />of an annual cover crop of annual oats (Avena stative) or winter wheat (Triticum <br />aestivum) will be planted on exposed soil to aid in stabilization and weed suppression <br />until a target species planting occurs. <br />5. Plant each respective planting zone with their respective bare-root seedlings and bur <br />oak container trees. Bare-root seedlings will be planted using a planting machine in <br />meandering rows to better imitate a natural forest. Container seedlings will be planted by <br />hand in the same rows as the bare root seedlings. All bur oak trees planted will require <br />grow-tubes and a support stake large enough to keep the tree upright immediately <br />following planting. <br />6. Assuming good growth, spot spraying an approved and appropriate herbicide in the fall <br />after the seedlings go dormant to help ensure that there would be minimal weed <br />problems during the following growing season trees in the second growing season if <br />necessary. <br />7. If the bare-root seedlings are not successful per performance standards listed in this <br />document, re-plant seedlings and install grow-tubes and a support stake large enough to <br />keep the tree upright immediately after planting. <br />8. If bur oak container trees are not successful performance standards listed in this <br />document, re-plant container tubes and install grow-tubes and support stakes large <br />enough to keep the tree upright immediately after planting. <br />9. If necessary, removal of grow tubes and support stakes when the tree exceeds tube <br />height and tree can self-support without the tree tube for upright growth.
