  2. Distribution and Changes in Abundance of Ailanthus altissima (Miller) Swingle in a Southwest Ohio Woodlot

    Espenschied-Reilly, Amanda L.; Runkle, James R.
    This study describes the population structure and dynamics of Ailanthus altissima within the Wright State University woodlot near Dayton, Ohio. This 80 ha woodlot contains both old growth and secondary stands. Ailanthus altissima populations were measured first in 1980 and again in 2001 and 2002. We examined changes in A. altissima demographics and patterns of occurrence by examining secondary environmental factors that could have influenced invasion and survival. Ailanthus altissima was found in 13.5% of the plots (500m2 each) and had a density of 198.4 stems/ha, an increase from 1980. Although usually at low densities within the interior, occasional high...

  3. Impact by North American Beaver (Castor canadensis) on Forest Plant Composition in the Wilds, a Surface-Mined Landscape in Southeastern Ohio

    Voelker, Bryan W.; Dooley Jr., James L.
    The impacts of Castor canadensis Kuhl (American beaver) on local ecosystems through foraging and dam construction activities have been well documented. Here we examined beaver foraging activity in the Wilds, an ecosystem in southeastern Ohio that was most recently subjected to surface mining between the late 1960s and the middle 1980s. Our objective was to make detailed observations of recent and past foraging patterns with the aim of better assessing the impact beaver might have on the recovery of forests in this altered landscape. One active site, a site downstream of the active impoundment and two recently abandoned beaver dam...
