Protecting Nova Scotia’s true boreal forest
Post on this website. It explains why true boreal forest in Nova Scotia is special while “borealized” Acadian forest is not.
What Is Forest Fragmentation and Why Is It A Problem?
One pager by Michael Snyder Autumn 2014 issue of Northern Woodlands. ” Ecologists suggest that true interior forest conditions – you know, where it’s hard to hear cars and lawnmowers and it remains cool, shady, and downright damp even during a three-week drought – only occur at least 200-300 feet inside the non-forest edge. And so a circular forest island in a sea of non-forest would have to be more than 14 acres in size to include just one acre of such interior forest condition. Put differently, reports indicate that the negative habitat effects of each residential building pocket within a forest radiate outward, affecting up to 30 additional acres with increased disturbance, predation, and competition from edge-dwellers.”

Voles and Moose, Fungi and Spruce
by John Pastor Autumn 2016 issue of Northern Woodlands/ “Have you ever wondered why patch cuts in the North Woods become carpeted with spruce and fir seedlings within a few years of being cut, while beaver meadows in the same area stay grassy for decades, or even centuries?” A fascinating storu of links between trees, mycorrhizal fungi and voles.

Recovery of late-seral vascular plants in a chronosequence of post-clearcut forest stands in coastal Nova Scotia, Canada
F.M. Moola & .L. Vasseur. Plant Ecology Volume 172, Issue 2, pp 183–197 . Abstract PhD Thesis “Although clearcutting had no immediate impact on overall alpha richness or diversity, the richness and diversity of residual plants declined after canopy removal and showed no evidence of recovery over 54 years of secondary succession. Consequently, compositional differences between secondary and late-seral stands persisted for many decades after clearcutting. Several understory herbs (e.g., Coptis trifolia (L.) , Oxalis montana (L.), Monotropa uniflora (L.)) were restricted to or attained their highest frequency and abundance in late-seral forests. These results suggest that the preservation of remnant old stands may be necessary for the maintenance of some residual plants in highly disturbed and fragmented forest landscapes in eastern Canada.”

New Brunswick forestry practices impact bird populations, says researcher
CBC Dec 18, 2016 “Even with the changes that have occurred in the landscape, Villard said “it is never too late” to help birds in the province. He noted there are still plenty of forests that haven’t been harvested and could be maintained.” He sees the issue as a political one and encourages the public to start asking questions about how forests are managed.
Interactions between white-tailed deer density and the composition of forest understories in the northern United States
Matthew B. Russell et al. 2-17. Forest Ecology and Management 384: 26–33
“Density above four deer km2 has been suggested as a population where deer densities could provide detrimental impacts to browse-sensitive tree seedlings. Our data suggest that less than 40% of northern US forests may have deer densities below this level.” Much of this paper is applicable to Maritimes.

A systematic approach for selecting focal species for conservation in the forests of Nova Scotia and Maine
K. Beazley and N. Cardinal.2004. Environmental Conservation 31: 91-101 “Focal species are a critical component of conservation planning, along with representation of ecosystems, special elements and ecologically sustainable management. They warrant conservation attention because they are functionally important, wide-ranging or space-demanding, habitat-quality indicators, ‘flagship’, and/or vulnerable or special populations…Species with the highest scores were identified as potential focal species, including wolf, cougar, lynx, river otter, eastern pipistrelle, wood turtle, four-toed salamander, golden eagle and Atlantic salmon.”
