Study area and site selection We defined the Mid-Atlantic as Virginia, Delaware, and Maryland, and parts of West Virginia, Pennsylvania, and New Jersey (Fig. The climate is humid and warm, with growing seasons ranging from 100 to 250 days (Stolte et al. Forest is the prevailing land cover type in the region, dominated by oak/hickory (Quercus spp. Emphasis was placed on the first three characteristics, because they are easily recognized within an older stand, and contrast strongly with conditions of younger forests. Carbon storage in old-growth forests of the Mid-Atlantic: toward better understanding the eastern forest carbon sink. Detailed methods of study area and site selection, field methods, data processing and analysis, and the comparison of old growth sites to the surround forest matrix. (2009), which utilizes: (1) the abundance of large, old stems, (2) abundance of standing and fallen dead wood at various stages of decay, (3) relatively few signs of anthropogenic disturbance, (4) a multi-layered canopy, and (5) canopy gaps. A total of 35 sites were identified for field visits. The majority of these stands were described in Davis (1996) and Kershner and Leverett (2004); others were identified sites in conversation with state forest agencies, and conservation and land trust associations (e.g., The Nature Conservancy).

If you look at the history of representation, it starts with the story of people representing numbers with straight lines, and crossing them after sometime. We established sampling points at 15-m intervals along a transect oriented to cover the greatest possible area of each stand (Fig. This BA estimation technique was intended to capture the range of structural variability present within the stand. LTER Network Office, University of Washington, Seattle, Washington, USA. We were conservative in our classification and erred towards identifying forest as secondary over old growth. We estimated total basal area (BA; m²/ha) of all stems within a variable radius of all sampling points using a 10-factor prism. Guidelines for measurements of woody detritus in forest ecosystems. Sherman; Volume 11: Dr Nick Lancaster, Dr Douglas J.Sherman and Dr Andreas Baas; Volume 12: Dr David R. Hupp; Volume 13: Dr Allan James, Dr Carol Harden and Dr John Clague; Volume 14: Dr Adam Switzer and Dr David M.What sunrise could be like and how sunset can leave mere humans unnerved is understood in its full impact only in a place like this and more in Mount Abu.
