Old Growth Forest Survey of Eastern Niagara Peninsula Phase 2/ Final Report
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.”
FOREST MANAGEMENT GUIDELINES TO PROTECT NATIVE BIODIVERSITY IN THEGREATER FUNDY ECOSYSTEM Second Edition
Greater Fundy Ecosystem Research Group Editors: Matthew Betts and Graham Forbes, 127 pages. Comprehensive. “The goal of this document is to provide a vision for forest management based on ecological processes.” Chapter 2: Amount of Mature Forest at the Landscape Scale by MG Betts et al. is particularly pertinent to “What is Old Growth?”
Old-Growth Forests: Back to the Future?
Post by Joe Rankin on Forest for Maine’s Future, Jan 29, 2019. An informative review of “Ecology and Recovery of Eastern Old-Growth Forests” published in 2018 by Island Press, edited by Andrew M. Barton, a professor of ecology at the University of Maine at Farmington, and William S. Keeton, a professor of forest ecology and forestry at the University of Vermont. Thx to BW for this one
If an Old Growth stand in Nova Scotia blows down, is it still Old Growth?
Post, Feb 4, 2019. “My answer, Yes, if the blowdown is not removed (e.g. as a salvage harvest)”
Annapolis County residents want ‘Old Growth’ Corbett Lake Crown forest left alone
Lawrence Powell in Annapolis Co. Spectator, Apr 30, 2019. “Biologist Bob Bancroft toured Crown forest at Corbett Lake April 28 and described it as intact and unique. He said a fraction of one per cent of forests in Nova Scotia are as complete with species and ground cover as the woods south of Bridgetown on the Neaves Road”

DECAY OF YELLOW BIRCH IN NOVA SCOTIA
M.A. Stillwell, Forest Chrinicle, march 1955
A study of the amount and types of decay in yellow birch, Betala Iutea
Michx. f., in Nova Scotia was undertaken in I951 and I952 in order to supply
those concerned with information necessary for proper forest management of
even-aged stands. A total of 374 trees was examined of which 35% contained
some measure of decay. Volume of decay increased with increasing age.
Approximately 50% of the trees contained decay at I20 to I30 years of age
and 100% at 230 years of age. The loss in merchantable volume increased from
a negligible amount at 60 years to about 10% at 240 years. No attempt was made to
predict a rotational cut based on diameter. A pathological rotation age of I70 years is suggested for yellow birch in Nova Scotia. Ten wood-destroying
fungi were found associated with rot in living trees, five in the butt and fiue in
the trunk. Poria cocos (Schw.) Wulf. caused the most frequent butt rot and
Fomes igniarius (L. ex Fr.) Gill. the most common trunk rot.
