Second growth forest as potential marten habitat in western Newfoundland: An examination of forest habitat structure and microtine abundance
(1996)
Abstract
IÂ examined two elements of marten (Martes americana) habitat, coarse woody debris (CWD) and microtine abundance, with respect to forest age and stem structure in western Newfoundland. Analysis of stem structure within a chronosequence of 19 second-growth stands indicated high intertree competition until stand senescence. Old-growth stands were less dense, offering more canopy openings. Lowest CWD volumes were observed within semimature to mature second growth. Highest levels of both CWD volume and structural complexity corresponded with stand senescence and old growth. Meadow voles (Microtus pennsylvanicus) were sampled within immature, semimature, mature, and overmature stands, and were most abundant within overmature stands (P $<$ 0.05). Results from this study suggest that the critical elements of marten foraging habitat currently are found within a senescent forest stand structure. Using a stand density management diagram, I designed a silvicultural system that simulates the structure of older forests within younger stages of forest development.
