Scott Starling Nature Sanctuary Wetland Restoration The Center for Earth and Environmental Science is restoring a mosaic of relatively rare and biologically diverse groundwater-fed wetland systems in the Scott Starling Nature Sanctuary portion of Eagle Creek Park. The restoration is occurring in areas that were historically fen and sedge meadow. CEES has established a broad coalition of stakeholders that include professional staff at the City of Indianapolis Department of Parks and Recreation, university faculty and staff, wetland restoration professionals from Spence Restoration Nursery, JF New and Associates, university students, corporate and community volunteers, Veolia Water Indianapolis, the Efroymson Fund of the Central Indiana Community Foundation, citizen groups representing the Starling Nature Sanctuary, and the area watershed task force. Site geophysical surveys and manual probing were used to locate the old agricultural tile drainage network which was installed by earlier settlers to drain the wetlands at the site. To date, approximately 1000 feet of the agricultural tile drainage network have been disabled or removed. Undergraduate and graduate student research is evaluating how the removal of agricultural tiles affects site hydrology given that many wetland complexes have been artificially drained and that wetland restoration includes hydrologic restoration through drain tile removal or disabling. Understanding the evolution of site hydrology and the effects of tile removal on hydrologic restoration has important implications for wetland restoration efforts. Groundwater monitoring wells, and piezometer clusters have been installed to monitor the level of the groundwater and track its chemical characteristics; several of the wells are instrumented with level-loggers and multiparameter probes. As the hydrology has been restored to the site, management continues with the removal of invasive exotic species and the installation of native genotype wetland plants. We anticipate that 60-70% of the eleven acre site will be returned to wetlands and associated habitats. The remaining area will be allowed to establish its own ecological setting based on ground wetness, elevation, and relationship to surrounding vegetation communities. Project Location, History and Setting The Scott Starling Nature Sanctuary is located at the north end of Eagle Creek Reservoir in Eagle Creek Park. It is situated in Pike Township of northwest Marion County on the Tipton Till Plain section of the Central Till Plain Natural Region of Indiana. The area was settled in the mid-1800s. Nearly all of the land on the north side of Fishback Creek was utilized for agricultural purposes during most of the twentieth century. Aerial photographs from 1936 show several areas that are now covered with young second growth forest were in row crop (Tungsevick, 1997). The area was purchased by the City of Indianapolis in 1966 as a portion of the land designated for the developing Eagle Creek Park and Reservoir. Several agricultural fields continued to be cultivated until 1991. The area was officially dedicated as the Scott Starling Nature Sanctuary in 1992 and is managed by Indy Parks and Recreation. The physical setting of the Nature Sanctuary is defined by Fishback Creek and its associated stream valley (Barr et al., 1996). The Fishback Creek valley is incised through Wisconsinan-aged glacial deposits and into pre-Wisconsinan glacial deposits, both of which are primarily till. The valley is characterized by a narrow floodplain and steep bluffs on the south and west sides of the creek. A broad floodplain with a gentle slope occupies areas north and east of the creek. Regionally, the location and landscape position of the contact between the Wisconsinan till and the older underlying tills provide a significant source of groundwater (Tedesco et al., 2004a; Tedesco et al., 2004b; Tedesco et al., 2003). Where this contact is near the ground surface, seeps develop. The presence and size of sand and gravel bodies at this contact controls the quantity of water available. In a more natural setting the type of wetlands formed by the seeps is controlled by the texture and drainage characteristics of the alluvium and the distance from groundwater seeps (Webber et al., 2004; Webber et al., 2003). In the modified setting of the Nature Sanctuary, Wilson Road forms a break in the natural landscape. Prior to the initiation of restoration efforts, several small seep faces had developed above and below Wilson Road. A key aspect of the wetland restoration at the Nature Sanctuary has been the identification and naturalization of these seeps. References Cited Barr, R.C., Hall, B.E., and Jewett, D.G., 1996.
