<br />below a node. Stem diameter will not exceed approximately 1 inch. Stem material 1-2 years old will be <br />preferred. Cuttings will be stored under freezing conditions, with a wet towel wrapped around the base of <br />stem bundles to prevent desiccation, until the time of planting. <br />To complete willow cutting planting, each cutting will be pushed into the ground such that 2 to 4 <br />inches of cutting remains above the seedbed surtace. The proximal end of each cutting will be dipped in <br />indolebutyrtc acid (IBA) prior to planting to promote root formation. Stem "polarity" will be maintained <br />throughout the cutting collection and planting process. <br />3.14 Tree Planting <br />Techniques to be used to plant trees will be those specified by the nursery supplying the stock or the <br />contractor employed to plant the trees. In any event, the techniques noted under 3.12 Seedling Planting <br />regarding hole formation, backfilling, and watering will be observed when planting trees. In addition, the <br />planting circle will extend from the drip line to the trunk of the tree at a minimum. All stock over five feet in <br />height will be staked according to accepted procedures to promote tree stabilization. Stock will be <br />watered during the first growing season following planting on a schedule to be determined by the <br />revegetation supervisor unless the stock is planted in the saturated soils of a constructed wetland. <br />3.15 Native Hay or Straw Mulching <br />Mulching will be conducted immediately following seeding operations. The mulch will be spread <br />evenly by hand or mechanical blower. When mulching slopes, application will be initiated at the top of the <br />slope, working down-slope, where possible. Mulch will not be spread when wind velocities would prohibit <br />even distribution. <br />Approximately 2.0 tons of mulch per acre will be applied to all areas to be mulched. Native hay or <br />straw materials will not be chopped so tine as to inhibit mulch effectiveness or proper anchoring. <br />3.16 Hydromulching <br />This technique can be used on steeper slopes to provide a mulch cover on areas too small to permit <br />native hay or straw mulching. Hydromulch will be applied at a rate greater than or equal to 1500 lbs. of <br />mulch per acre. Rates up to 3,000 to 3,500 lbs. per acre may be required for steeper slopes and or <br />critical areas. A tackitying agent will be added to the scurry to ensure mulch stability. The pH of the mulch <br />slurry will be greater than or equal to 3.5. This technique will be applied immediately after seeding but will <br />not be applied under freezing conditions or over standing water. The hydromulch machine should be <br />equipped with an emulsion induction system. <br />10 <br />
