CI i mate, <br /> soi I s,topography,and aspect are maj or factors affecti ng the sui tabi I i ty of pl ants <br /> for a particular site and these factors vary widely across North Carolina,with <br /> the most significant contrasts occurring among the three major physiographic <br /> regions of the state—Mountains, Piedmont, and Coastal Plain. Sub-regions <br /> of the state should also be considered. For example,the Triassic Basin in the <br /> Piedmont region may have characteristics that call for special soi I treatment, <br /> I i mi ted plant selection, and special maintenance. ven within the riparian <br /> area, there may be need for different species depending on site conditions <br /> (i.e., dry sandy alluvial floodplains with wet pockets). Therefore, thoughtful <br /> pl anni ng i s requi red when sell ecti ng sped es for i ndi vi dual si tes i n order to <br /> maximize successful vegetation establishment. <br /> Native seed and plant species are included on the plant list in Appendix 8.02 <br /> of this manual. <br /> The design professional should note that regardless of the benefits and <br /> advantages of native seeds and plants, there are potential issues if proper <br /> pl anni ng, i nstal I ati on and mai ntenance do not occur. These may i nd ude: <br /> • Potential for erosion or washout during the establishment stage; <br /> • Seasonal limitation on suitable seeding dates and availability of seed and <br /> pl ants <br /> • Adaptability of species at specific sites; <br /> • Availability of water and appropriate temperatures during germination <br /> and early growth and <br /> • Lack of maintenance to control invasive plants and undesirable <br /> competition. <br /> PLANTING <br /> • ee —Prepare the seed bed as described above in soil preparation. Apply <br /> seed at rates specified on the plans, and/or as recommended in Tables <br /> 6.11a-c of this manual, with a cyclone seeder, prop type spreader, drill, <br /> or hydroseeder on and/or into the prepared bed.
