| Big Forestry in Nova Scotia, the forestry folks in the Nova Scotia government and the federal forestry folks in Canada like to point out that there has been very little deforestation in NS and in Canada at large, that “Canada’s forest laws are among the strictest in the world”. This, the feds say, is evidence enough that “Canadian forests are healthy, productive and thriving.”
Critics have maintained that while the forest cover may not have changed, forest degradation has occurred though conversion of older forest to younger forest and though species simplification, e.g., see NRDC, 2017

–A second scientific paper by MG Betts & colleagues further documents “Forest Degradation” in Maritime Canada
Post on this website, Oct 31, 2024. “It’s difficult to understate the significance of this paper given the recent efforts of the E.U. to bring in regulations that limit exports and imports of forest products associated with “deforestation” and “forest degradation” while the Canadian forest industry and the federal government contend that our forestry practices are fully sustainable and express concern that such regulations would create unfair trade barriers for Canadian wood exports. The results and conclusions from this recent “Carbon Paper” and an earlier “Bird Paper” by MG Betts & colleagues, both based on data for forests in Maritime Canada, lend a lot of credence to recent protests in Nova Scotia over forest degradation associated with harvesting of remaining patches of Old Forest in landscapes on Crown lands. Likewise, the 2024 “Carbon Paper” does not support the contention of Forest NS that growing secondary forests lock carbon away more effectively than unharvested forests in Protected Areas.”

– Congruent Long-Term Declines in Carbon and Biodiversity Are a Signature of Forest Degradation
MG Betts et al., Oct 30 2024 in Global Change Biology “Recent global policy initiatives aimed at reducing forest degradation require practical definitions of degradation that are readily monitored. However, consistent approaches for monitoring forest degradation over the long term and at broad scales are lacking. We quantified the long-term effects of intensive wood harvest on above-ground carbon and biodiversity at fine resolutions (30 m2) and broad scales (New Brunswick, Canada; 72,908 km2). Model predictions for above-ground biomass were highly correlated with independent data (r = 0.77). After accounting for carbon stored in wood products, net CO2 emissions from forests for the region from 1985 to 2020 were 141 CO2e Tg (4.02 TgCO2e year−1; 32% of all reported emissions). We found strong positive correlations between locations with declines in above-ground carbon and habitats for old-forest bird species, which have lost > 20% habitat over 35 years. High congruence between biodiversity and forest carbon offers potential for policy incentives to conserve both objectives simultaneously and slow rates of forest degradation. These methods could be used to track forest degradation for managed forest regions worldwide.”
– Deforestation: Definitions, Trends, and Policies for Forests and Forest Products
Kathryn Fernholz et al., for Dovetail Partners, Feb 2023. [“Dovetail seeks to engage you in thoughtful, collaborative processes so that we can create an inspiring path forward and empower you to lead with confidence. Dovetail seeks to accomplish that by providing authoritative information about the impacts and trade-offs of environmental management, including consumption choices, land use decisions, and policy alternatives. Dovetail is a highly skilled team that fosters sustainability and responsible behaviors through collaboration to develop unique concepts, systems, models, and programs. Dovetail excels at solving complex problems and helping responsible organizations succeed. We also help define programs that increase the job creation and the job quality of resource-based industries. Dovetail Partners is a 501(c)(3) nonprofit corporation.”] “This report explores our understanding of deforestation – starting with the terminology – and examines recent global trends and policy actions. Effective strategies to address the negative impacts of deforestation require a greater shared understanding of long term land use trends, robust and elegant cross-commodity policies (i.e., linking food and forest production systems), and scalable actions, including substantial investment, from diverse public and private sector leaders at all levels. Unfortunately deforestation continues for social and political reasons to be a significant global problem, and there are limits to our measurement processes. We can observe, count, and record land conditions – but to understand change we also need to know the intentions of landowners, policy makers, and other influencers. A great deal of work is underway to address deforestation. From private companies reducing their impacts, to policy actions and investment in restoration activities, there are many working models of success to build from. With continued global collaboration and innovation there is good reason to be optimistic about the future of the world’s forests.”
