<br />various combinations of methods will allow sequencing to be tailored to the site and soil types. <br />Generally, operations will be performed in an order which maximizes the effectiveness of all of <br />the combined treatments. Normally, planting will be performed after surface roughening and <br />before mulching operations. There are several exceptions to this commonly used sequence. <br />One occurs when land imprinting is used with drill or broadcast seeding methods. In this case <br />seeding, mulching and then land imprinting is performed. When a colter is employed for <br />crimping, the machine will be capable of anchoring mulch at a depth of 2 inches. A minimum <br />space of 12 inches between cotters will be allowed. Whenever possible anchoring will be <br />performed at right angles to prevailing winds or on the contour. [f a disk is to be used for <br />anchoring, mulch will be spread and anchored prior to seeding operations. Disking will be <br />perfottrted on the contour or at right angles to prevailing winds. Broadcasting or drilling of <br />seed will be performed immediately following mulch applications. When seed is drilled. <br />operations will follow disked rows to the extent this is practicable. <br />Green manure, compost or other commercially available mulch products may also be used for <br />mulching. A variety of geotextile fabrics may be used to "mulch" critical area plantings. <br />Specialty mulches and geotextile fabrics will be applied per manufacturer's recommended use <br />and application rates for the situation in which they are used (Table 11). <br />To avoid nitrogen deficiency, l0 pounds of available nitrogen fertilizer will be applied per <br />1.000 pounds of mulch material. Reconstructed soils with higher concentrations of wood chip <br />mulch added during develolment operations may require additional nitrogen supplementation <br />to offset potential nitrogen deficiency. In such areas, it is normally recommended that 20 <br />pounds of nivogen per ton of wood mulch will be applied for three consecutive years <br />following seeding. <br />The use of soil amendments and supplemental fertilization will be avoided on reconstructed <br />soils of the Thirteenmile Tongue formation. These uses will be restricted in an effort to avoid <br />impacts to the soils that represent the future potential T&E species plant growth medium. <br />Revegetated areas will be monitored for adequate germination and establishment. Vegetation <br />stand establishment and development will be observed annually in the later part of the growing <br />season following seeding and may continue for several years thereafter. Stand germination and <br />establishment may take several growing seasons before full expression of the seed mixture is <br />realized. Many xeric plant species will not germinate until specific environmental conditions <br />occur. Seed can rem:un dormant and viable for such species for many years. Fur this reason <br />full expression of seeded materials may take several years to occur. Therefore, adequate time <br />will be taken in evaluating the initial success of revegetation efforts. Patience during initial <br />evaluations will avoid needless work and minimize the application of excessive amounts of <br />seed. <br />Interseeding or other necessary corrective measures will be timely undertaken when interim <br />monitoring results indicate they are needed. Interseeding will be performed using a no-till drill <br />or a broadcaster. Broadcast interseedings will utilize appropriate methods for covering the seed <br />following application. Methods will be chosen based upon the level of vegetation stand <br />development, soil surface conditions and the intended purpose of the Interseeding. Chaining, <br />land imprinting, raking, harrowing and cultipacking are methods that may be considered for <br />covering seed planted by Interseeding operations. <br />In limited areas. it may be desirable to transplant bare root, tubling or other nursery stock to <br />facilitate establishment of specific plant species. Such areas may include high visibility <br />locations, sites with high erosion potential, reforestation areas or critical wildlife habitat. <br />~rrxrican Soda L.L.P. 5-10 <br />Soil Conservation.
