On the Theory and Practice of Forestry in Nova Scotia
for the non-forester (like me)
These are some of the resources I have found useful. As well as an interest in conservation and other issues related to forests and forestry, I have a practical interest in managing a small (22ha) piece of land belonging to my family that supports a mature mixed forest. There are clearcuts on either side.
If you didn’t grow up with it, learning about forestry is almost like learning a new language. A glossary can help. ‘Cant access the Canadian Forest Service Glossary anymore.

Ecological Forestry: Days 2-4 (Maine Public Lands 1)
On Family Forests (facebook Group). “Maine’s 600,000 acres of public land have been managed for more than 30 years to produce older, larger, and more diverse stands of trees native to the Acadian Forest. Dr. Robert Seymour (in red), professor emeritus of forestry at the University of Maine, has been a member of the silvicultural advisory committee for state-owned woodlands since 1986. Retired forester George Ritz (in green) managed about 80,000 acres of public lands during that same period. In today’s clip, Seymour talks about implementing ecological forestry on Maine’s public lands. William Lahey’s “Independent Review of Forest Practices in Nova Scotia,” released in August 2018, recommended that Nova Scotia also embrace this approach to forest management. Our first question: What is ecological forestry?
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.

Silvics of Common Nova Scotia Trees
Appendix 2, page 23 in Spruce – Pine Management Guide by Tim McGrath et al, updated Feb 2017. It gives the ages for maturity (full seed production), over-maturity, info on shade tolerance and longevity. “Knowledge of the characteristics (Silvics) of common native trees in Nova Scotia is critical in understanding how forest management activities affect regeneration, growth and succession. The Forest Management Guides (FMG) use stand maturity, longevity and shade tolerance characteristics to prescribe appropriate prescriptions. Harvests are optimally timed after they become mature and before over-maturity. Harvesting after maturity increases opportunities for natural regeneration. Timber losses are avoided if harvesting takes place before over-maturity as slow growth and increased mortality occur at this age.”
For convenience, I copied the silvics page and added the age of first seed production: View Silvics + age of first seed production

Silvicultural Discipline to Maintain Acadian Forest Resilience
by Peter Salonius. 2007. Northern Journal of Applied Forestry 24(2): 91-97. ABSTRACT: “Clearcut harvesting decreases structural complexity, eliminates old and genetically superior legacy trees, extirpates mature-forest floor vegetation, and creates hot and dry postharvest microclimates. The short-lived, exposure-tolerant, boreal tree species that regenerate in large forest openings are believed to be less able, than the late-successional Acadian species they replace, to adapt to the climate warming expected during the next forest rotation. A strip silviculture design is presented that includes limited canopy opening, “no-traffic” areas, maintenance of “full-cycle” survivors, and programmed return harvest intervals that approximate natural gap disturbance as a means of arresting the further increase of boreal species and restoring Acadian species on the landscape. Within the confines of this silvicultural discipline, two management options are described to accommodate extremes of future energy availability.”
Challenges facing gap-based silviculture and possible solutions for mesic northern forests in North America
Christel C. Kern et al. 2017. Forestry 90 (1): 4-17. “Gap-based silvicultural systems were developed under the assumption that richness, and diversity of tree species and other biota positively respond to variation in size of harvest-created canopy gaps. However, varying gap size alone often does not meet diversity objectives and broader goals to address contemporary forest conditions… We pose a revised concept for managers and researchers to use in prescriptions and studies focused on integrated overstory and understory manipulations that increase structural complexity within and around canopy openings.”

Leaving a Legacy (Video)
Association for Sustainable Forestry (NS), 2011. “This video [in 3 parts] reviews three forest improvement treatments that promote tree quality and manage for multiple age classes. These treatments include selection management, crop tree pruning, and crop tree release. Selection management is used to create and maintain uneven- aged forest conditions, enhance tree growth, and encourage natural regeneration. Crop tree pruning and crop tree release are used to increase the quality and value of individual trees. This video gives and overview of implementing these treatments from the perspective of various woodlot owners across Nova Scotia.”
Integrating Natural Disturbance Parameters into Conventional Silvicultural Systems: Experience From the Acadian Forest of Northeastern North America
Paper by Robert Seymour, 2005, P. 41-48 In: Peterson, C.E. and Maguire, D.A., editors. Balancing ecosystem values: innovating experiments for sustainable forestry. USDA For. Serv. Gen. Tech. Rep. PNW-GTR-635. 389 Available at http://www.fs.fed.us/pnw/publications/gtr635/GTR635a.pdf, text pages 41-48. ABSTRACT: “With rare exceptions, the presettlement Acadian forest of northeastern North America was driven by gap dynamics; true stand replacing disturbances were quite uncommon, with recurrence intervals of many thousands of years. After centuries of human exploitation, stand age structures have become simplified, and commercial timber rotations are a fraction (15 to 40 percent) of the lifespan of the common late-successional tree species. Adapting silvicultural systems to strengthen their ecological foundation thus confronts the challenge of converting single- or two-cohort stands to more complex structures via various combinations of regeneration and retention… A hybrid system is described that combines the proven benefits of shelterwood with the restoration advantages of group selection; in American terminology, the system is an irregular group shelterwood with reserves, similar to the German Femelschlag in which gaps are created and gradually expanded over several cutting cycles.

Nova Scotia’s Fiery Past: Why early wildfires ignited by our ancestors should not justify modern clearcutting practices
Guest post by Donna Crossland on Medway Community Forest website, Sep. 4, 2015. “The harvest practice of clearcutting more closely mimics a stand-replacement wildfire event (although the effects are not identical), while partial harvests emulate small blow downs or tree mortality caused by insects or diseases. Thus you can see why it is important to accurately define the natural disturbance dynamics that characterize Acadian forests.”

Guide to FSC Certification for Woodlot Owners in Nova Scotia
Produced by MTRI. The general approaches to management of an Acadian forest promoted by FSC (Forest Stewardship Council) are described. Chs 7,8, 9 provide a lot of natural history and guidelines on how to manage a forest to replicate as much as possible the natural forest. “Specifically, this guide attempts to answer the following questions:
– What is forest certification, and what is the Forest Stewardship Council?/ What benefits can certification offer to woodland owners?/
What does a woodland owner have to do to become certified?/ What are the benefits to joining a group of certified woodland owners?”

Operational trial of the selection cut using the 123 method In collaboration with NewPage Port Hawkesbury (2011)
“… the 123 method was developed to allow harvesting operations under the concept of a “perpetual forest cover” system. This method meets the uneven-aged management regime requirements because it permits the three basic silvicultural functions—harvesting, tending, and regenerating—in one operation. Application of the selection cut in softwood forests using the 123 method developed by FPInnovations addressed wildlife habitat concerns, maintained visual quality of highly valued landscape, and provided alternatives in ecosystem-based management schemes… [In this study] A stand mainly composed of sugar maple, located in nearby Heatherton, Nova Scotia, was selected as a replacement for a group selection cut… The trial results show that the selection cut using the 123 method can be used to manage hardwood forests.” Another trial was conducted in 2013: Operational trial of the Selection cut using the “123” method at Northern Pulp Nova Scotia Corporation, with seemingly promising results. Curiously or at least regrettably, the report(s) by FPInnovations on application of the 123 method to softwood forests seems to be no longer available.

An Ecological Approach to Riparian-Buffer Definition, and Implications for Timber Harvests in Nova Scotia, Canada
Patricia Stoffyn-Egli1 & Peter N. Duinker 2013. In Journal of Sustainable Development; Vol. 6, No. 12; 2013
A study was conducted in the The Upper Mersey River (UMR) watershed to examine implications of a 50 m riparian buffer (NS requires only 20). “The delineation method has been applied using spatial analysis to a watershed in Nova Scotia, Canada. A 50-m buffer represents 15% of the watershed terrestrial area. Excluding timber harvest in this buffer decreases the total potential harvestable volume by 11% compared to provincial regulations and by 7% compared to the practices of the local forest-products company. The simplicity of the proposed riparian buffer delineation lends itself to easy implementation by any landowner with little training and cost, a distinct advantage considering the urgency of protecting freshwater ecosystems. Moreover, continuous buffers can serve as wildlife movement corridors throughout the watershed and are thus an essential component of connectivity planning at the landscape scale.”

Pockwock – Bowater Watershed Study: Wind Damage in Streamside Management Zones
Daralyn McCurdy and Bruce Stewart, NSDNR. 2008. “The highest concentration of blowdown and soil exposure occurred along the clearcut edge where the trees were most exposed. In all cases blowdown and soil exposure levels declined as distance from the cut edges increased, except in the 1 m strip along the stream edges. Blowdown and soil exposure next to the stream was highest in the 20m thinned SMZ’s. Although there was more blowdown and soil exposure recorded for the 30 m thinned watersheds compared to the 20 m unthinned watersheds (average), there was less blowdown and soil exposure in the 10 m strip next to the stream in the 30 m thinned watersheds, suggesting that the penetrating effect of the wind was reduced, thereby lessening wind throw. Blowdown damage near the stream in the 30 m thinned watershed was very light, and similar to the untreated control watersheds. To maintain the highest integrity of stream side forest after a harvest, these early results suggest that the use of a 30 m SMZ is favourable in these conditions.”
Providing More Acadian Forest Wildlife Habitats in Today’s Managed Forests
Referenced article by Bob Bancroft.~2009. “There is a need to incorporate more missing features of original Acadian forests into today’s managed forest landscapes. Many of these features can be located in riparian zones, which are lands beside waterways that have a disproportionately high amount of use by wildlife. Riparian zones are a potential means to connect the landscape for wildlife.”

EAC document. “We reviewed and synthesized information sources that examine yield, regeneration, stand composition, costs, revenue and employment generated by clearcutting and partial cutting systems in the Acadian and other forest types in north-eastern North America with the aim of informing an analysis of the potential impacts of reducing the prevalence of clearcutting in Nova Scotia.”
Implementing Complex Partial Harvests in Central Maine: Is Tree Marking Necessary?
Sam Grimm, University of Maine MS thesis, 2015 Advisor: Robert S. Seymour. “In northeastern North America, tree marking — the simple designation of cut or leave trees to implement a given silvicultural prescription — has declined, in favor of reliance on machine operators to implement written or verbal prescriptions. This study is among the first to explore the costs and benefits of tree-marking in complex mixed-species stands typical of the Acadian region.”

Forest Roads: A Synthesis of Scientific Information
Hermann Gucinski et al. 2001 . USDA Forest Service, Pacific Northwest Research Station, General Technical Report PNW-GTR-509 May 2001. 120 pages. Abstract: Effects of roads in forested ecosystems span direct physical and ecological ones (such
as geomorphic and hydrologic effects), indirect and landscape level ones (such as
effects on aquatic habitat, terrestrial vertebrates, and biodiversity conservation), and
socioeconomic ones (such as passive-use value, economic effects on development
and range management). Road effects take place in the contexts of environmental
settings, their history, and the state of engineering practices, and must be evaluated in
those contexts for best management approaches.
Danny George on getting value from your wood 3 videos by Paul Bissonnette
“The release of Peter Murphy’s and ACALA’s video “It’s TOO Big – Biomass” was designed to be a stark one sided look at the Point Tupper Biomass Plant. There was need to shock the public into realizing what was happening in Nova Scotia the forest industry.
“While operating a camera for this video. One of the comment that stuck in my mind was a statement from Danny George: If the logging industry (as it is now) was to shutdown it would be the best thing to happen. A value on industry would slowly evolve.
“After it’s was released I received permission to edit my version based around Danny George’s comment. Danny’s 40+ years of experience in the logging industry was used to show how to take as much value out of the logs as possible before shipping the unusable rest to the Biomass plant. The three trees in the videos would have have very little value as the price at that time was around $49 a ton delivered. Harvesting them only for Biomass with out proper knowledge how to abtain the most value value is simple throwing hundreds of dollars out the window. Simply stated burning gold.

SELECTION CUTTING IN RED SPRUCE A Comparison of Methods Establishment Report
Bruce Stewart et al., 2009. NSDNR. “The goal of this research is to develop a scientific understanding of forest response to selection cutting that will lead to effective selection management techniques and guidelines. It is designed to study treatment effects on growth and yield, tree quality, regeneration, age class structure, blowdown, and a range of ecological parameters including coarse woody debris, structural diversity, plant species diversity and dynamics of large retained legacy trees. The trial has a longterm outlook (75+ years) that will include periodic treatments and regular measurement cycles. It will involve management manipulations targeting basal area retention, light availability, species selection, and quality improvement.

Homogenization of the terrestrial water cycle
Delphis F. Levia et al., 2020. Nature Geoscience 21 Sep 2020. “Land-use and land-cover changes are accelerating. Such changes can homogenize the water cycle and undermine planetary resilience. Policymakers and practitioners must consider water–vegetation interactions in their land-management decisions… the global coverage of forest plantations increased from 167.5 million ha in 1990 to 277.9 million ha by 2015… These land conversions are changing water demand: forest plantations with fast-growing, short-rotation species are likely to use more water compared to indigenous vegetation and older plantations…Both deforestation and reforestation efforts seldom consider the consequences for the resilience of the water cycle to stressors…Current global trends in land-use change towards monocultures are risking a more homogeneous terrestrial water cycle with consequences for planetary resilience. Policymakers and practitioners should design forests and agricultural systems that embrace the differences among plant species to maintain the variation in the hydrological response of the land surface in both rural and urban areas. By recognizing, preserving or enhancing the nature-based resilience inherent in the diverse array of hydrological responses among plant species, we can provide better stewardship of the Earth’s finite water resources.”
