Primary species will be planted over <br />approximately 80% of the planting surface according to water depth and species <br />(-Jf-C ,".The remaining species will be planted in smaller areas within the wetland. The overall <br />planting interval will be up to 1 plant/1.5 meter (emergent planting zone), or up to 1 plant/1.5 <br />meter (shoreline plantings). Specific growth habits (particularly depth tolerance) will be <br />considered when determining planting locations for each species. Other potential species that <br />may be suitable for shallow planting areas are: Carex ssp., Cyperus virens, Echinochloa walteri, <br />Eleocharis Montana, E. palustris, Leersia haxandra, Rhynchospora corniculata, Schoenoplectus <br />americanus, and Utricularia sp. Many of these plants were identified in the reference wetland <br />shown on st,. * ar, The final planting list will depend upon species availability at the time of <br />planting. Plants will be obtained from local sources (within 150 miles). Commercial nursery <br />grown stock and/or wild stock from donor sites may be utilized. Since the wetland water levels <br />are designed to fluctuate from month to month, the wet area during the first growing season <br />following construction will determine the actual planting area. Transitional areas within the <br />wetland footprint (typically 0-0.3 feet depth at full pool) will not be planted with obligate wetland <br />Benchmark Ecological Services, Inc.
