By Bruce Kershner Project of Bert Miller Nature Club. Final Report to Trillium Foundation, October 2004, Native Tree Society Special Publication Series: Report #13. Very relevant to NS right now, e.g., provides “Visual Categories of Old Growth”, “Old Growth Bark (“Antique Bark”)”, “Indicators that a Site May Not Be Old Growth”, “Pit and Mound Shapes on the Forest Floor”
External Characteristics of Old Trees in the Eastern Deciduous Forest
Neil Pederson Natural Areas Journal 30(4), (1 Oct 2010).
“Six common external characteristics of old angiosperm trees include: (1) smooth or “balding” bark; (2) low stem taper; (3) high stem sinuosity; (4) crowns comprised of few, large-diameter, twisting limbs; (5) low crown volume; and (6) a low ratio of leaf area to trunk volume. ”
New Estimates of Massachusetts Old-growth Forests: Useful Data for Regional Conservation and Forest Reserve Planning
Anthony W. D’Amato et al. 2006 NORTHEASTERN NATURALIST 13(4):495–506
“We estimate that the total area of old-growth in the state is 453 ha, in 33
stands that range from 1.2 to 80.9 ha in size…Several criteria were applied in the field to help identify old-growth forests: 1) the absence of any evidence of past land-use (e.g., cut stumps, stone walls or structures, numerous multiple-stemmed trees); 2) the presence of at least 5 old trees (> 225 years old; indicating establishment prior to European settlement in these locations and exceeding 50% of the maximum longevity for species commonly encountered ) per hectare in the forest overstory as determined through the collection of increment core samples; and 3) the existence of forest structural characteristics that are often indicative of old-growth condition, such as pit and mounds, large snags, gnarled tree crowns, and the accumulation of large volumes of coarse woody debris.”
