Primary species will be planted over approximately 80% of the planting <br />surface according to water depth and species. The remaining species will be planted in smaller <br />areas within the wetland. The overall planting interval will be 1 plant to a maximum of 1.5 meter <br />spacing (emergent planting zone), or 1 plant to a maximum of 1.5 meter spacing (shoreline <br />plantings). Specific growth habits (particularly depth tolerance) will be considered when <br />determining planting locations for each species. Other potential species that may be suitable for <br />shallow planting areas are: Carex ssp., Cyperus virens, Echinochloa walteri, Eleocharis <br />Montana, E. palustris, Leersia haxandra, Rhynchospora corniculata, Schoenoplectus <br />americanus, and Utricularia sp. Many of these plants were identified in the reference wetland. <br />The final planting list will depend upon species availability at the time of planting. Plants will be <br />obtained from local sources (within 150 miles). Commercial nursery grown stock and/or wild <br />stock from donor sites may be utilized. Since the weUand water levels are designed to fluctuate <br />from month to month, the wet area during the first growing season following construction will <br />determine the actual planting area.
