A field guide to forest biodiversity stewardship
Peter Neily and Glen J. Parsons. NSDNR 2017. The 126 page guidebook contains a lot of useful information primarily at “the forest stand level”, encourages managers to retain legacy trees, patches of old growth etc. and for some specific situations or wildlife such as as nesting colonies of great blue heron offers very specific instructions on how to protect them. The Eco Notes in each section provide interesting, relevant and practical information about forest biodiversity that will be welcomed all people who have an active interest in our forests regardless of whether they actually manage any forest.

Celebrating Yellow Birch
Post on this website. “Yellow birch is chuncky, slow growing, a tree of damp, shady ravines, of swamps and rocky hillsides. It grows slow and dies old. For company it prefers other shade lovers like sugar maple, hemlock. Red spruce and beech – that club of elites we call the Acadian forest. Its bark is so rough and gnarly, especially on older trees, people hardly know it’s a birch.” – Gary Saunders in My Life with Trees, Gaspereau Press, 2015

Woodlands shaped by past Hurricanes
By David Dwyer, Forester NSDNR. 1979
“Many of our forest stands in Nova Scotia are a result of past hurricanes. Mounds on the forest floor -the result of uprooted trees – indicate this. The age of trees growing on these mounds give a good indication of when the storm occurred. These stand ages compare well with the written records of past storms…”

EDMUND S. TELFER: Continuing Environmental Change -An Example from Nova Scotia
Canadian Field-Naturalist 118(1): 39-44.
ABSTRACT: Information from personal experience, from community elders and published literature served as a basis for evaluating environmental changes in the District of North Queens and adjacent areas of Southwestern Nova Scotia over the past century. Major events included disappearance of the Caribou (Rangifer tarandus), the arrival of White-tailed Deer (Odocoileus virginianus), the severe reduction of Canada Yew (Taxus canadensis), disappearance of Lynx (Lynx canadensis), a major dieoff of Striped Skunks (Mephitis mephitis), decline of American Beech (Fagus grandifolia), the loss of mature birch (Betula spp.), the severe reduction of Moose (Alces alces), the arrival of the American Dog Tick (Dermacentor variabilis) and Coyotes (Canis latrans), and the restoration of Beaver (Castor canadensis). The proximate cause of many of those changes were plant and animal disease, while the ultimate causes were naturally occurring animal range expansion and human impacts. The warming of the climate over the past 150 years probably played a role. The nature and timing of the events could not have been predicted.
Beetle Diversity Associated with Forest Structure including Deadwood in Softwood and Hardwood Stands in Nova Scotia

Saproxylic beetle (Coleoptera) communities and forest management practices in coniferous stands in southwest Nova Scotia, Canada
Philana E. Dollin, Christopher G. Majka & Peter N. Duinker, ZooKeys 2(2) · September 2008 pp291-336.
Old-growth forest in Nova Scotia typically exhibits an uneven-aged, multi-layered stand structure and contains significant amounts of coarse woody debris. Many forest species, including invertebrates, depend in various ways on deadwood substrates. The objective of this study was to investigate relationships between forest stand age, silvicultural treatment, dead wood, and invertebrate biodiversity, using saproxylic beetles as an indicator group. Saproxylic beetle communities were also compared in the context of other studies in Nova Scotia. Beetles were gathered using four collection techniques: pitfall traps, funnel traps, sweep-netting, and manual searching. Results show that both stand age and harvest treatment had an effect on species richness and species composition. Younger stands had lower species richness and hosted a significantly different suite of species than medium-aged or older ones. Similarly, harvested stands had lower species richness and were host to a significantly different suite of species than unharvested stands. The results from the investigation of stand age are of particular interest. Forest management that disregards the dependence of different suites of beetles on forest stands of various ages and compositions, emphasizing even-aged single-species stands, may be harmful to the species diversity of Nova Scotia’s forest ecosystems

Beetle diversity associated with forest structure including deadwood in softwood and hardwood stands in Nova Scotia
Daniel Kehler, Søren Bondrup-Nielsen* and Cristine Corkum Proceedimgs of the NS Institute of Science 42: 227-239, 2004
ABSTRACT: Associations between beetles and forest stand characteristics, as well as beetle diversity, were investigated for 41 forest stands in Nova Scotia, Canada. Over 200 morphospecies from 45 Familiesof beetles were caught using window flight-intercept traps. In both years, correspondence analysis revealed distinct groupings of softwood and hardwood stands based on species assemblages. Multiple regression analysis was used to determine associations between forest variables and total species richness. Analyses were conducted for all stands combined and for hardwood and softwood stands separately. Hardwood stands had greater beetle richness than softwood stands. Within hardwood stands, volume of intermediate-sized deadwood was the best predictor of total species richness. Within softwood stands, volume of well-decayed deadwood was the best predictor of total beetle richness. Deadwood volume was associated with stand age in softwoods, and it appears that over 140 years is required for deadwood volume to reach pre-disturbance levels.
