Description of Site and Environment In 2000-2001, an empty Higgins' eye pearlymussel shell was collected from Upper Pool 3 (RM 815) of the Mississippi River (near the area where the St. Croix River enters the Mississippi River) (Kelner and Davis 2002). Since 2000, individual Higgins' eye pearlymussels have been transplanted from areas near Cassville, Wisconsin, and Cordova, Illinois, to Pools 2 and 3 near Minneapolis and Hastings, Minnesota, respectively. Additionally, cleaning of mussels infested with zebra mussels and artificial propagation and release have been conducted to alleviate the effects of zebra mussels on the Higgins' eye pearlymussel (Hornbach 2004). The State-listed creek heelsplitter is a widespread but generally uncommon species. It generally occurs in fine gravel or sand substrates of small- or medium-sized rivers (NPS 2004). Host fish species for the creek heelsplitter include the spotf in shiner, guppy (Poecilia reticulata), slimy sculpin (Cottus cognatus), black crappie, and yellow perch (NPS 2004). It is most common, but seldom abundant, in headwater streams (Siteman 2003). The black sandshell, which is also State-listed, is a widespread but generally uncommon species. It occurs in medium to large rivers, in gravel or firm sand substrates (NPS 2004). Host fish species include common carp, green sunfish, bluegill, largemouth bass, rock bass (Ambloplites rupestris), and white crappie (NPS 2004). It can be common to abundant where it occurs (Siteman 2003). 2.2.6 Terrestrial Resources The plant site comprises approximately 2150 ac and has roughly 2 mi of shoreline on the north and south banks of the Mississippi River in Wright and Sherburne counties (NMC 2005a,b). The Monticello site is located in an upland region of low relief dominated by rivers, streams, and lakes (NMC 2005a). Land use within the region is primarily agricultural; therefore, natural deciduous climax vegetation communities previously found within the city limits of Monticello have been reduced to remnant patches of maple (Acer spp.), basswood (Ti/ia americana), elm (Ulmus spp.), oak (Quercus spp.), and hackberry (Celtis occidentalis). These remnants are restricted mostly to larger river islands and small isolated pockets along the river banks (AEC 1972). Prior to European settlement, the southern sections of the Upper Mississippi River Basin, where Monticello and its associated transmission line corridors are located, were a mix of prairie, wetland prairie, oak woodland, brushland, and maple-basswood forest (MPCA 2000). Terrestrial habitats on the Monticello site include formerly cultivated fields in various stages of ecological succession, with remnant climax hardwood forest in isolated pockets along the river and on the larger islands, and some actively cultivated fields (AEC 1972). Of the 2150 ac encompassed by the Monticello site, the majority of acreage is located on the southern side of the Mississippi River, with approximately 450 ac on the northern side of the river (NMC 2005a). Approximately 50 ac are developed and occupied by the Monticello plant and supporting facilities, with an additional 174 ac leased to local farmers for row crop production (NMC 2005a). Approximately 144 ac are leased for recreational purposes, while the remainder is undeveloped. NUREG-1437, Supplement 26 2-24 August 2006 1
Description of Site and Environment The terrestrial habitats near the Monticello site support a variety of plant and animal species that are typical of free-flowing, upper-midwestern rivers (NMC 2005a). In general, facilities in use at the Monticello site are located on previously cultivated areas and consist of early succession forbs and grasses. Upland forests on the Monticello site are predominately northern pin oak (Quercus ellipsoidalis), green ash (Fraxinus pennsylvanica), basswood, and prickly ash (Zanthosxylum americanum). Forested wetlands on the northeast bank of the river and the river islands include American elm (Ulmus americana), box elder (Acer negundo), silver maple (A. saccharinum), cottonwood (Populus deltoides), and black willow (Salix nigra) (MCBS 1998). MNDNR has identified the following native plant communities as occurring on the Monticello site: floodplain forest, silver maple-Virginia creeper floodplain forest, bur oak woodland, oak woodland brushland, willow swamp, dry oak savannah, and dry prairie. Representative localities are as follows: the floodplain forest community is known to occur on the northeast bank of the Mississippi River and on the portion of the Monticello site in Wright County. The silver maple-Virginia creeper floodplain forest community is found to occur on Cedar Island (NMC 2005a). Patches of bur oak woodland community occur south and west of the power block (Hoffman 2004). Two patches of oak woodland brushland occur adjacent to the river in Sherburne county (Hoffman 2004; Delaney and Epp 1993; MNDNR 1993). The willow swamp community, dominated by shrubby willow (Salix spp.), occurs on Oxbow Island located on the north side of the Mississippi River and downstream of the station. An area of dry oak savannah occurs on the Sherburne County side of the site, on the first terrace north of the Mississippi River (NMC 2005a). An area of dry prairie occurs to the west of the power block on the narrow sloping area between the railroad right-of-way and the Mississippi River (NMC 2005a). Extensive farming, logging, and grazing have occurred throughout these plant communities, which are, therefore, much changed from the original climax condition (AEC 1972). There are no public waters or wetlands Within the Monticello site that are designated as protected under Minnesota Statute 103G.005 (MNDNR 1983, 1984, 2004a), although the U.S. Fish and Wildlife Service (FWS) National Wetland Inventory indicated that wetlands exist along the Mississippi River and on islands as seasonally flooded patches of scrub-scrub, deciduous forest, and emergent vegetation (DOI 1991). Mammals typical of the area and identified within the Monticello site include white-tailed deer (Odocoileus virginianus), red fox ( Vulpes vulpes), raccoon (Procyon lotor), red squirrel (Tamiasciurus hudsonicus), grey squirrel (Sciurus carolinensis), short-tailed shrew (Blarina brevicauda), southern red-backed vole (Cleithrionomys gappen), meadow vole (Microtus pennsylvanicus), mice (Peromyscus spp.), pocket gopher (Geomys bursarius), white-tailed jackrabbit (Lepus townsendii), beaver (Castor canadensis), muskrat (Ondatra zibethicus), gray fox (Urocyon cinereoargenteus), coyote (Canis latrans), fox squirrel (Sciurus niger), chipmunk (Tamias striatus), mink (Mustela vison), weasels (Mustela frenata, M. erminea, M. nivalis), and striped skunk (Mephitis mephitis) (AEC 1972; NMC 2005b).
