CODDLE CREEK RESERVOIR <br /> <br />EVIDENCE IN SUPPORT OF MITIOATION pLANTINO SCHEME: AN ANNOTATED BIBLIOCRAP~ <br /> <br /> As indicated in the Environmental Assessment and EA Appendix G, 186 <br />acres of shoreline around the new reservoir will be planted with five species <br />of bottomland hardwoods, includin§: red maple (Acer rubrum), boxelder <br />nefundo), sweetgum (Liquidambar scyraciflua), green ash (Fraxinus <br />pennsylvanlca) and American sycamore (Plaranus occidentalis). Following the <br />distribution of 2-6 inches of litter/mulch from existing lowland areas, hare <br />root stock seedlings will be installed in parallel rows perpendicular to the <br />shoreline (up the hill away from the water) on 10-foot centers. <br /> The normal (average) pool of the reservoir is proposed to be 646' MSL, <br />with maximum flood pool reaching 650' MSL periodically during the first half <br />of each year. Trees will be installed in the surcharge zone (1-15 fee[ above <br />normal pool, periodically inundated) between 648' and 650' MSL. It is <br />anticipated that green ash, and to some extent box elder, will tolerate the <br />deeper flooding expected between 648' and 649' MSL by the inundation of the <br />maximum pool of the reservoir, while red maple, sweetgum and American sycamore <br />will thrive on the saturated soils and minimal flooding affecting the higher <br />elevations (649' to 650' MSL). If species survivorship is poor at certain <br />elevations, individuals of that species will be replaced by individuals of <br />species which show good survivorship at those elevations. In all cases, <br />species diversity will be maximized wherever possible. The following evidence <br />has been collected to support these contentions. <br /> <br /> 1 Baker, J.B. ].977.

After the <br /> Trees had leafed out in May, 3 ft of water was pumped on to the plots, <br /> all trees were completely inundated for ~ weeks, and then the water was <br /> removed. Green ash and sycamore were consi~tent].y most.tolerant of <br /> spring flooding; survival was about 90%. These species main[slued <br /> surviving'seedlings one season after flooding'and growth was highest for <br /> green ash (2.8 ft) followed by sycamore (2.4 ft) and sweetgum (1.2 <br /> <br /> 2 Christensen, N.
