100 m. from river and bordered by steep upland toeslope.;On 2 m. high, flat terrace. The center is sparsely covered with numerous Carex sp. while the outside perimeter of the plot is poison ivy, Carex intumescens and other herbs. Soil is the same in both the Carex and poison ivy zones of the plot (2 cores taken). Looks like a bare patch in the woods, but the Carex diversity is very high. Sites like this one are very uncommon here and not found downstream.
