1.- are scattered individuals of New Jersey tea (Ceanothus americanus) and grey goldenrod (Solidago nemoralis). A scattering of young Siberian elm, green ash (Fraxinus pennsylvanica), boxelder, and a juniper or two also occurs in this area. Further to the northeast of the corner, the open field labeled 2c1 has a scattering of many of the same dry prairie elements, including bush clover and native grasses. However, this area has been heavily disturbed and is even more depauperate than the area identified previously. In addition to smooth brome grass, butter - and -eggs (Linaria vulgaris), giant mullein (Verbascum thapsus), and quack grass have become co- dominants. In some locations, bush clover and sand drop seed (Sporobolus cryptandrus) are present, and in other locations, brome grass, yarrow (Achillea millefolium), quack grass, and little else are found growing. At the northeast end of the open field along the Highway 35 ROW there is another small patch of open dry prairie (6b) with many of the same species previously mentioned, except in this location there are additionally a few stems of white sage (Artemisia ludoviciana), showy goldenrod (Solidago speciosa), patches of gum plant (Grindelia squarrosa), Canada tick trefoil (Desmodium canadense), several small, suppressed clumps of big bluestem (Andropogon gerardii), and several remaining clumps of New Jersey tea. Two junipers occupy this area, and young oaks are encroaching from the savanna edge to the north. Recommendation: This comer area is a very high visual amenity for southbound traffic on Highway 35. Restoration and management of this intersection area would involve implementing a prescribed buming and herbiciding program to reduce the existing non - native grasses and to stimulate oak regeneration and expansion of existing dry prairie remnants, followed by reintroduction of native grasses and forbs where necessary. Brushing of the invasive Siberian elm and boxelders, and perhaps eastern juniper (although this is a desirable native in this location), could also be a part of the potential restoration program for this area. A wetland area along the Highway 35 ROW is dominated by reed canary grass (Phalaris arundinacea) (4d) and includes a small pocket of cattail (Typha spp.) (4c) within the ROW of the Highway. This area also includes such native plant species as blue vervain (Verbena hastata), lake sedge (Carex lacustris), and giant goldenrod (Solidago gigantea).
