Of approximately 65 acres in the Hutcheson Memorial Forest about 82% is situated on well-drained sites while the remainder occupies soil that has poor drainage. For the purposes of this paper, data collected from these two situations are considered separately for both cover and gap closure.

Land abandonment is increasing as human influence on the globe intensifies and various ecological, social, and economic factors conspire to force the cessation of agriculture and other forms of land management. The “old fields” that result from abandonment have been the subject of much study, yet few attempts have been made to examine the larger questions raised by old field dynamics. Old Fields brings together leading experts from around the world to synthesize past and current work on old fields, providing an up-to-date perspective on the ecological dynamics of abandoned land. The book gives readers a broad understanding of why agricultural land is abandoned, the factors that determine...
Millions of urbanites never see primeval forests during their lives except for the old growth forests found in urban parks. Unfortunately, these forests are on the verge of disappearing because arboreal reproduction is lost to human trampling and park administrators and urban foresters do not maintain these “natural” forests. To aid urban foresters and park managers in meeting the challenges, research on old growth forests in urban parks is synthesized in terms of historical ecology to introduce the methods utilized to reveal long-term forest composition changes. The case study of three stands in Fairmount Park, Philadelphia, PA relates pre-chestnut blight tree species densities and post-chestnut blight arboreal changes to fire and visitor trampling. The information gained on how urban old growth forests have developed and changed is used to develop restoration ecology based frameworks to restore species composition and address challenges to forest survival including invasive species.
A fascinating account of woodland natural history for all those concerned with woodland management and ecology.
