REVEGETATION GUIDELINES (CONTINUED) <br />page 2 <br />1. 47eed and seed free grass hay or grain straw should be used at an <br />application rate of 4,000 lbs. per acre of air dry material. <br />At least 5G~ of the mulch by wiight shall be 10 inches or more in <br />length. Anchor mulch immediately after distributing with mulch <br />crimper (straight disc). <br />~~ <br />2. Application of feedlot or barnyard manure must be of a type that has <br />60$ or more, by weight, heavy chunks 5 inches or more in diameter. <br />The minimum rate of application shall be 30 tons per acre immediat ly <br />before or after seeding. ` <br />3• Mulch netting. Netting must be firmly held in place with pins spaced <br />not more than 10 linear feet apart. In sandy or extremely loose soil <br />locate pins closer. <br />4. Asphalt <br />5. Jute Netting <br />6. Excelsior mat ~~ <br />7. Wood chips <br />5. Defer seeded area from all use be livestock for at least a tuo year period <br />--until grass is established. This may require fencing of the <br />critical area. <br />SEEDBED PREPARATION FOR VERY STEEP SLOPES <br />.`..._ <br />1. Cut ridges, diversions or channels across slope to catch excessive water <br />on slope and divert it off of disturbed area. Spacing of these will depend on <br />degree of slope and intensity of rain. The steeper the slope, the greater the <br />intensity of rains the closer the ridges, diversions or channels. Broadcast <br />seed and drag, spike tooth harrow, chain logs, anything that will scarify soil <br />and cover seed with some soil. <br />2. Run bulldozer with tracks up and down slope. The track trill leave de- <br />pressions perpendicular to the slope. These depressions will catch the seed i,,,,~ <br />that is broadcast, hold any precipltation on the slope and help control the <br />movement of soil off the disturbed area. Broadcast seed before equipment goes <br />over area for this final operation. The movement of the equipment will tend to ~ <br />cover seed with soil. <br />3• Leave area without the final smoothing operation. Leave the surface rough <br />with ridges and depressions. This will slow the runoff down to allow it to <br />percolate into soil and reduce erosion. Broadcast seed and drag, spike tooth <br />harrow, chai^ logs, anything that will scarify soil and cover seed with some <br />soil. <br />4. If site is to extreme for these practices broadcast seed over area and <br />cover with mulch or net will be needed. Composted wood chips mulch is very <br />cell suited for mountain sites, since a supply of chips is readily available <br />in these areas. These will help reduce .erosion and loss of soil moisture <br />through evaporation. <br /> <br />
