2 Located in the South Carolina Botanical Garden Located in the South Carolina Botanical Garden Previously abandoned dump site with highly eroded land Previously abandoned dump site with highly eroded land Pond created 10 years ago as part of storm water management plan Pond created 10 years ago as part of storm water management plan Only inflow of water for this.36 acre pond is storm water runoff Only inflow of water for this.36 acre pond is storm water runoff Restoration plan is in development by the Botanical Garden Restoration plan is in development by the Botanical Garden GIS data shows an average of 53 inches of precipitation per year and soil type is Cecil Sandy Loam (ClC2) at a 6% to 10 % slope GIS data shows an average of 53 inches of precipitation per year and soil type is Cecil Sandy Loam (ClC2) at a 6% to 10 % slope

8  Identify Goals and establish sequence of restoration steps  Locate reference site  Appoint restoration team and leader  Develop site specific goals  Reduce slope on surrounding banks to a approximately 4:1 to control erosion  Create Bioswale or Rain garden in areas of higher erosion potential (“funnel” area and drainage pipe area) to control sediment and contaminant flow into the pond  Replant slopes with native grass species (Panicum, Andropogon and Sorghastrum) to control erosion and sediment and contaminant flow into the pond

9  Develop site specific goals (cont…)  Plant area directly surrounding pond site with wetland plant and tree species (willows, sedges, rushes, arrowheads, Juneberry, Sweetshrub) to control sediment and contaminant flow into the pond and create wetland ecosystem  Place bird and bat boxes in surrounding areas to help minimize insect populations  Place path and benches surrounding pond site to encourage public interaction but limit access to less sensitive areas  Identify funding sources and determine labor sources  Monitor restoration progress
