1. In the Maritime Provinces the term "old growth" is employed with some variability, however, it is generally taken to indicate relatively undisturbed stands of climax or sub-climax composition where the majority of dominant trees in the upper canopy have attained at least half the maximum longevity for that species. In practice this means stands where trees average 150 years (sugar maple, yellow birch, beech), 200 years (red spruce and white pine) or 300 years (eastern hemlock) depending on species composition.
1 Species recorded from five or fewer specimens representing <0.005% of specimens from the region. Information is compiled from Majka (2006, 2007), Majka and Jackman (2006), Majka and Pollock (2006), (Majka et al. 2006, 2007a).
