Here, results are presented from the second sampling effort at Dysart Woods, an old-growth, mixed-mesophytic remnant tract in southeastern Ohio. In 2011, trees, saplings, shrubs, herbs, and soils were sampled in permanent plots established in 1996, allowing a direct fifteen–year comparison. Mortality and recruitment rates revealed that while most species at Dysart Woods are decreasing in abundance, sugar maple and American beech are rapidly increasing in importance, as is the invasive Alliaria petiolata. This shift in composition may be due to beech and sugar maple showing little negative responses to neighbors, and/or reflect increasing pressures that old-growth forests face from invasives. Such findings have considerable implications for the future of Dysart Woods, and developing appropriate management techniques may be required to preserve its integrity.","abstract_html":"Documenting change in the composition and structure of forest communities is important for understanding the distribution and abundances of natural resources, carbon pools, and species.
