OSee Appendix A (section Contouring and Earth Work) for descriptions of <br />methods and concepts. <br />Final Seed Mix <br />(Construction Materials Rule 3.1.10 (1), (4) and 6.3.4 (1c)) <br />The final seed mix was selected to support the ranching operation and <br />provide a sustainable forage source for both livestock and wildlife. The <br />selected species also have been proven to perform well at stabilizing <br />disturbed site (Table 5). Further, the selected species in the primary seed <br />mix have been shown to prevent weedy species such as cheat grass (Bromus <br />tectorum) from becoming established. The following are recommended: <br />1. <br />Seed should be planted between September and March to take <br />advantage of the bimodal precipitation distribution (Figure 1). <br />Z. <br />Seed can be drilled or broadcast. Rough terrain will probably be <br />broadcast. <br />3. <br />Broadcast seeding rates are doubled (or more) from the drill rate. <br />4. <br />Broadcast seeded areas should be dragged, harrowed, or rafted to <br />incorporate seed into the soil. A dozer can also "walk" the seed in, <br />keeping the tracks at 90° to the fall line. <br />5. <br />Forage kochia should be broadcast in late fall through early winter on <br />disturbed soil of a light snow covering. Freshly harvested seed should <br />be used for forage kochia if possible. <br />6. <br />Alternative species are acceptable and are provided in the Table 5. <br />This allows substitutions when cost for some species rise or become <br />unavailable. The consideration of an alternative forb such as Lewis <br />flax is recommended. <br />7. <br />In general, with some exceptions, germination is improved with seed <br />that has been handled and stored properly and it has been less than <br />two years since harvest. One exception is Indian ricegrass <br />(Achnatherum hymenoides). It is suggested that fresh seed be used. <br />8. <br />Prepare the seed bed as previously suggested using proper soil <br />amendments, organic materials, ripping, disking, chisel plow, and <br />implement erosion control measures. <br />9. <br />Control grazing by fencing if needed. <br />101 <br />The sources, references, and criteria for the seed mix species selection are <br />found in Appendix H <br />381 Page <br />Ertl, 11071-LLLc.3ilblE NI %1111 DtLY!LRNNCH <br />BAKINlNV11VINMINI!1LAND NUU,NIRS -W1VVv.CR1-%3RA1flN1tiVIL.C,`,.%4 <br />
