    Rachel Holt presents Old Growth Forests: What is the path forward? to alumni of UBC’s Faculty of Forestry.
    In her presentation, Holt refers to a critique produced by Veridian Ecological in response to COFI’s claim (through a study authored by forester Cam Brown) that 29.3 percent of all old forest in the province has a site index greater than 20 metres. You can read that response here.
    In the section on “Jobs” in her UBC presentation, Holt refers to the “number of jobs per cubic metre.” She doubtless meant to say the “number of jobs per thousand cubic metres”. An excellent analysis of what the big issues are right now regarding continued logging of old-growth forests and the logging industry’s denialism.
    Following Holt’s and Brown’s presentations at UBC, they got together to uncover common ground. Holt wrote a short paper outlining that common ground. This is also useful in understanding the issues around the amount of remaining old growth. You can read that paper here.

    Managing Northern Goshawks and many of our other larger animal species that depend on old forests will not be achieved simply by old growth deferral of the most at-risk old forests. It is critical that we quickly move beyond the deferrals to the ultimate goal of effective landscape planning, with ecologically appropriate targets for forest retention at the core.
    Review of the remaining known active Northern Goshawk territories in the Skeena Region indicates that:
    • Although helping to support the nesting and foraging requirements of Northern Goshawks, old growth deferrals as being proposed will be insufficient to maintain the population or the viability of individual territories.
    • However, if these now scattered and often disjunct old growth deferral areas were strategically designated within the remaining contiguous large tracts of forest—including the more productive valley bottoms—they could immediately provide very effective habitat cornerstones supporting the needs of Northern Goshawks, and a wide range of other focal old growth species.
    Lessons learned from 25 years of monitoring and research on Northern Goshawks in B.C.
    In west central B.C., there has been a precipitous decline in the population of Northern Goshawks as a direct result of clearcut logging (rate and extent of cut), and subsequent conversion of primary forests to short-rotation tree plantations. Northern Goshawks are year-round residents of our forest landscapes, where they are the apex avian predator within old forests. These large hawks are adapted to hunt beneath the canopy of these forests, where from hidden perches they ambush. They rely on fully functioning, older forest ecosystems, to provide the diversity and abundance of food they require (squirrels, grouse, hares, forest songbirds, etc.). They were once common in the region; now instead of thousands of pairs, we have a few hundred. Because their breeding areas and core foraging home ranges are usually located at lower elevations, nearly all known and “still occupied” territories are threatened by additional planned timber harvest. Logging to date has forced regional Northern Goshawk populations to the to the brink of viability, and we now must focus management on maintaining the remaining viable territories.
    Northern Goshawk Habitat Needs
    Species such as Northern Goshawks that evolved in old growth-dominated forest landscapes need mature and old growth forest to survive and thrive.
    Like the vast majority of our forest birds and mammals, pairs of Northern Goshawks are territorial, and historically distributed themselves evenly across the forested landscape. The birds forage in the forest around their nests, and radio telemetry/GPS tracking studies have shown how the size of this foraging home range fluctuates through the year, according to prey abundance and habitat. They are year-round residents in their territories, and to breed they need sufficient food to survive the winter, sufficient food for the female to form and lay eggs in April, and sufficient food in spring and summer for the birds to reside and raise the young in their foraging home range.
    Through the collective work in our landscapes, we now understand that a goshawk’s breeding area is a fixture in the landscape, and the birds will use the same specific area for generations of birds. The size of the breeding area is governed by habitat competition and nest territoriality with other goshawks in the landscape. As such, by visiting these sites, biologists know very clearly how many birds there are, and how well they are responding to changes in their home range area. When the breeding area is excessively logged or burned, the birds do not seek other territory (already abandoned due to forest modification or presently occupied), resulting in further territorial abandonment. In fact, approximately 90% of the 150 known Northern Goshawk breeding areas within the Skeena Region are now quiet and are, or soon will be, abandoned. Unless we change how we manage our forests, we will never see the return of this species to historic breeding areas, and will further witness their extirpation across landscapes.
    In the Skeena Region, breeding pairs are spaced regularly every 4-6 km in old-growth forests. This pattern and the validating research using radio telemetry show that in summer Northern Goshawk breeding home areas range from 2,400 to 4,000 ha, and in winter this expands to an area 2 or more times as large (3,000 – 8,000 ha). Within a breeding area, habitat analysis shows that on average ~75% of the forest cover is composed of mature and old-growth stands. This ~75% requirement for mature and old growth is an average. Many territories will fail before the ~75% level is reached, and nearly all will fail if we manage for just the lowest level (~60%) observed for an active territory in our region.
    Northern Goshawk Habitat Management Challenge
    Forests at a landscape scale (think Northern Goshawk home range area; several 1,000s ha), are a vast tapestry of several different tree species, stand types and ages, and myriad site types (understory vegetation, patchiness, wetlands, landforms, slope aspects, moisture status, etc.). This biophysical complexity affects the overall abundance of the birds and other animals within any given area. Given this complexity and the availability of prey species for Northern Goshawks, there is no definable home range boundary that we can determine prior to timber harvesting (i.e., we cannot identify a habitat threshold for each territory that will ensure that the birds will have enough food). Each territory threshold is unique and could vary year to year.
    Chillingly, for many species requiring larger tracts of older forest, habitat management is now about deciding which species and in what abundance we want to occupy our forested landscapes. Planning for these species will fail if left to chance, minimum thresholds, or deregulated resource industries and depopulated management agencies.
    Rising to the Management Challenge:
    Currently in the Skeena Region a team of biologists and foresters, in partnership with government, forest licensees and First Nations, are responding to the above findings. The focus is on developing Tactical Plans to maintain a viable long-term Northern Goshawk population, through the management of probable and known individual territories across given landscapes.
    Integral to this approach is the integrated stewardship direction laid out by the BC Minister in "Together for Wildlife Strategy" (Doug Donaldson 20 August 2020, https://engage.gov.bc.ca/wildlifeandhabitat/), and the Forest Practices Board identified need for wildlife management to be built around a Tactical Plan (FPB. July 2019. Tactical Forest Planning: The Missing Link Between Strategic Planning and Operational Planning in BC. https://www.bcfpb.ca/reports-publications/reports/tactical-forest-planning-the-missing-link-between-strategic-planning-and-operational-planning-in-bc/).
    At all scales, these long-term tactical plans must focus on the retention of the old growth structure that supports the requirements of Northern Goshawks and their prey (and of course apropos today’s Climate Change headlines - this same structural retention will help mitigate flooding, rising stream temperatures, and greenhouse gas emissions). In B.C. we have a wealth of forest research, and we already know what combination of forest retention, timber harvest and post-harvest silvicultural techniques can deliver appropriate stewardship for Northern Goshawks while still allowing for timber extraction.
    Not surprisingly, maintaining habitat for the large home range needs of Northern Goshawk also supports the habitat needs of many other forest dwelling wildlife species, including Fisher, Marten, Wolverine, Grizzly Bear, Moose, Caribou, Spotted Owl among others.
    Fundamentally, stewardship of many of these species requires a new and long overdue approach to management of our forested landscapes, addressing the need for large unfragmented areas as cornerstones to wildlife species management. The ongoing discussion regarding old growth deferrals sets the stage for revitalized land use planning, and is a stepping-stone to ensuring support for keystone species such as the Northern Goshawk. Strategic placement of deferrals within the already mapped ~200 suitable Northern Goshawk territories in the Skeena Region could quickly provide the initial outcome that is urgently needed, as outlined in the integrated stewardship direction identified in the “Together for Wildlife Strategy”. Northern Goshawks and many other old growth dependent species are relying on us.

    OVER THE PAST THREE DECADES, forest sector employment has decreased by about half, from about 100,000 jobs in 1991-1999 to about 50,000 in 2010-2018 (1). Various factors have been proposed as responsible for this loss including mechanisation, loss of accessible fibre, increased wildfire and beetle disturbance, increased raw log export, increased area in protection, etc. It’s possible to use federal statistics to tease apart some of these factors. If increased protection, increased natural disturbance or loss of accessible timber were responsible for most of the job loss, the volume and/or area harvested would decrease. However, if increased mechanisation and/or raw log export were responsible, the jobs would decrease while volume and area harvested remained stable (i.e., jobs per unit volume would decrease).
    Although the volume harvested per year has fluctuated somewhat (with a drop around the 2008-2009 recession), volume per decade has remained relatively constant at about 70 million cubic metres over the past three decades. Volume harvested has decreased somewhat in the last decade, about 10% from the 1990s and 2000s, partly due to decreased cut post-beetle and partly due to regional shortages of accessible, merchantable fibre (and subsequent mill closures). This small drop contrasts strongly with the larger drop in the number of jobs per volume. The number of jobs per unit volume harvested has dropped from an average of 1.3 jobs per thousand cubic metres in the 1990s to three quarters of a job per thousand cubic metres from 2010-2018:

    Figure 1. Jobs per 1000 cubic metres
    This decline in jobs per unit volume suggests that mechanisation, and perhaps raw log exports, are responsible for most of the loss rather than decreased area available for harvest due to protection, loss of fibre or increased disturbance (which would reduce volume harvested not jobs per volume).
    Properly quantifying the effects of mechanisation and log exports on job loss requires accounting for the effects of volume harvested. Using the jobs/cubic metre average for the 1990s as a baseline (1.3 jobs per thousand cubic metres) and projecting expected jobs forward from 2000 to 2018 based on the volume harvested per year estimates that 25,000 jobs were lost to mechanisation and perhaps raw log export by the 2000s and 38,000 jobs were lost by the 2010s (lost jobs calculated as the average difference between projected jobs and actual jobs over the decade in Figure 2).

    Figure 2. Jobs projected based on annual volume harvested and jobs per cubic metre values (1.3 jobs/thousand cubic metres 1990s baseline) compared to actual jobs. The blue line represents the maximum jobs in the past three decades.
    From a high of about 100,000 jobs, decreased volume was only responsible for a large part of decreased jobs during the 2008-2009 recession (compare the dotted line to the blue horizontal line); a decrease in jobs per unit volume was responsible for most of the job loss. This change was likely due primarily to increased efficiency in mills and increased mechanisation of harvest. Analyses done elsewhere suggest an annual loss of 3,600 jobs due to raw log export (2).
    Increased natural disturbance may reduce volume available for harvest, contributing to job loss. Natural disturbances are salvaged where possible. The increased volume harvested around 2005 was due to uplifts in AACs for mountain pine beetle salvage.
    Wildfires burned 3.5 million hectares of forest in the past decade, about half in the THLB. While much of the merchantable THLB may be salvaged, some will be inaccessible and some volume will be lost to char. If a quarter of disturbed THLB area cannot be salvaged, for example, fires will remove about 21,000 hectares of harvestable timber per year based on trends over the last decade. Assuming the current jobs per hectare (0.75 jobs per cubic metre) and stocking of 350 cubic metres per hectare, wildfires can be inferred to be responsible for a loss of 5,500 jobs each year.

    Len Vanderstar’s Review, June 1, 2021
    My comments below are based on a review of the Intentions Paper released on June 1, 2021. Given that what was presented today by the province is an intentions document, by default it is not binding at this time, so my comments must take this into account. Without getting too deep into the subject matter and from my perspective, I have listed pros/semi-pros & cons associated with the provincial government’s intentions with respect to modernizing forest policy.
    • Reaffirms government’s commitment to UNDRIP, however the Declaration on the Rights of Indigenous Peoples Act already applies to B.C. laws, but implementation delay remains problematic with respect to an action plan and progress report.
    • Increasing opportunity for new entrants in the forest sector, thus possibly supporting diversity and small business.
    • Forest tenure re-distribution and revising tenure disposition considerations, with the intent to increase indigenous replaceable forest tenure opportunity and local community forest tenure options.
    • Re-affirmation of implementing the recommendations from the Old Growth Strategic Review Report (Gorley-Merkel), however one of the key recommendations of an immediate moratorium on @ risk old-growth has been misapplied based on manipulative false data.
    • Improvement of FRPA – tactical planning approach to better consider forest values with up- front Indigenous involvement, and re-instituting Statutory Decision Maker authority to reject a cutting or road permit based on resource stewardship concerns... “could irreparably impair other forest values”.
    • Beginning to recognize a need for transition from maximizing timber volume to optimizing product value.
    • Advance a process to minimize the burning of slash piles and freeing up fibre for product manufacturing, although no mention was made of minimizing the creation of slash.
    • Increasing penalties for poor practices and behaviour with the intent to increase the deterrent.
    • Forest tenure holders to be held accountable to harvest profiles expressed in the AAC to avoid the continuous of preferential stand harvest.
    • Re-integration of prescribed fire into forest management with a focus on wildfire mitigation and habitat creation.
    • Some very vague language that I am interpreting, but requires clarification, to actually base the AAC on growth & yield plots rather than hypothetical model growth projections... “consider limits on timber harvest until provincial silviculture investments have optimal harvest opportunity in consideration of risk and other values.”
    • Unabated logging of valued old-growth forests remains an ongoing concern; legitimate concern still exists with the talk and log scenario.
    • Seemingly lack of recognition of the biodiversity crisis recognition in our forests; no forest structure & function management direction, although the commitment to implementing the Old Growth Strategic Review recommendations is mentioned, and one of the recommendations speaks to prioritizing ecosystem health and resiliency.
    • No recognition that AACs must be reduced to prevent further loss/extirpation of forest dependent species.
    • No mention of science-based factual data or core foundation advice to drive informed decision making. This is a major concern for the Science Alliance for Forestry Transformation. Where are the independent scientists?
    • Compensation for lost harvesting rights may not translate to actual loss of volume of logs being transported to mills currently holding forest tenures, so public fund compensation should be carefully administered.
    • Lack of commitment to reduce whole log export, just ability to audit fee-in-lieu of manufacturing (this was not being done before?). Four to five million m3/yr. of whole log export greatly reduces domestic employment and associated personal income tax to government.
    • Re-distribution of tenure without acknowledging the first step to ensure adequate forest protection/conservation may result in an ineffective roll-out.

    British Columbia Forest Policy Reforms Needed for Sustainability
    By Karen Price, Rachel Holt, Dave Daust, Phil Burton, Jim Pojar, Dave Coates, Jay Gilden, Len Vanderstar
    BRITISH COLUMBIA’S forest management policies urgently require reform to sustain ecosystems and communities, and to help address the current climate and biodiversity crises. Priorities include:
    1) revised land use plans that protect more primary forest,
    2) more realistic timber supply analyses, and
    3) reformed forest tenures that better reflect community needs.
    B.C.’s forests, particularly productive old growth, are critical for mitigating climate change and maintaining biodiversity. Retaining carbon-dense old forests is a very effective natural climate solution, key to meeting 2050 emissions targets. Old growth resists wildfire, ameliorates flooding and drought, reduces temperature, and provides climate refugia. B.C. bears a global responsibility for biodiversity and carbon sequestration because of its globally rare, productive, coastal and inland temperate rainforests. Increased retention also addresses Canada’s commitment to protect 30% of representative ecosystems by 2030. Retention priorities were not adequately implemented following land-use planning in the 1990s, largely due to provincial policies that continued to favour industrial timber interests.
    B.C.’s timber supply is declining and rural communities face crisis. Supply fall-downs have been anticipated for decades, but ignored by successive governments. Optimistic timber supply models, that underestimate the effects of disturbance and a changing climate, have contributed to unsustainable harvest rates, biodiversity declines and community instability. Additionally, preferential harvest of productive sites has left lower volume and higher cost stands, exposing mills to closures. Timber supply projections must include current science on growth rates, mortality, and climate change, and must partition harvest by productivity.
    Over recent decades, forest jobs in B.C. have declined as a few large corporate players—including provincially-managed B.C. Timber Sales—dominate management, converting an inherited supply of old growth forest to short-term economic benefit. A forest tenure system that gives oversight to forest-based communities may better support Indigenous rights and sustain multiple ecological and social values.

    Science Alliance for Forestry Transformation: Who are we?
    We are scientists and applied science forest professionals with expertise and experience in terrestrial and riparian ecology, biodiversity, wildlife, disturbance dynamics, forestry, climate change, land-use planning, risk assessment, cumulative effects, resilience and landscape analysis (including timber supply). We are not social scientists or economists. We have worked on collaborative land-use planning around the province and are intimately familiar with barriers to success as well as potential pathways through the gauntlet of vested interests to the greater public interest.
    Our big ask: reform forest management to sustain ecosystems and communities
    Update land use planning, with an increased emphasis on protection of primary and old-growth forests;
    Adjust timber harvesting levels, supported by more realistic determinations of allowable annual cuts to promote sustainable forestry practices;
    Reform forest tenure, with greater community and indigenous control of forest management to increase social, environmental and economic resilience.
    Approach: base decisions on science and acceptable risk
    Forest management often ignores or obfuscates science that conflicts with short-term economic objectives, thus threatening ecosystem and community sustainability.
    Sufficient scientific knowledge does not exist within the ministry. A changing baseline, poor institutional memory, continuance of business-area silos, innumeracy, senior bureaucrats with limited vision, and naïve young staff lacking mentors mean that lessons are lost and issues remain unresolved. A culture of “getting to yes” means that problems are swept under the rug.
    Splitting the ministry provides the opportunity to introduce science-based decision-making, for example via a Chief Ecologist/Scientist and Independent Scientific Panels. Land-use planning provides opportunities to prioritize goals that bring long-term benefits to society, biodiversity and climate. Incorporating science in planning is critical to ensuring that management strategies work towards the goals.
    Context: climate and biodiversity crises
    We live in a time of unprecedented global crisis: the climate is almost out of control (1), we are participating in a great extinction event (2), and our societal systems have increased human vulnerability (3). At the same time, a social awakening to inequality and push for change led by youth provides an opportunity to act (4).
    The set of suggestions outlined below follow in the wake of our “Big Ask” as critical action items to address the climate and biodiversity crises.
    Challenge: legal and policy direction prioritizes timber
    BC’s existing land-use plans have been, for the most part, ignored. As planning moves through the system, public intent is lost because industry speaks loudest. Many consensus objectives remain in the non-legal realm and subject to professional reliance…which has failed: rather than meeting intent, implementation aims to extract the most resources. Existing plans are out-dated, excluding climate change, new resource activities, and current science; many lack substantive First Nations’ engagement (5).
    Suggestion: use land-use planning to retain more old growth forest
    BC’s primary forests (6), particularly productive old growth ecosystems, are critical for mitigating climate change, adapting to climate change and maintaining biodiversity and ecological integrity. Land-use planning provides a mechanism for considering the well-documented importance of old forest and improving management accordingly.
    Scientific Rationale:
    Old forests store vast amounts of carbon (7). Retaining carbon-dense old forest is the most effective natural climate solution, far superior to planting trees, and critical to meeting 2050 emissions targets designed to prevent catastrophic change. Ecosystems with infrequent disturbance that grow large trees (i.e., coastal and inland temperate rainforest) are most important to protect.
    Harvesting old forests releases carbon (8). From 40 – 66% of carbon is lost to the atmosphere after harvest. More is lost through processing, meaning that “long-lived wood products” store a quarter or less of the carbon in a standing forest. Harvesting forests for bioenergy emits more carbon than using fossil fuel sources.
    Replacing old forests with young does not recover stores (9). It takes 100 to > 250 years to recover the stored carbon after logging; shorter rotation (<80 years) managed stands never recover the carbon of a natural forest. Carbon sequestration cannot replace carbon stores.
    Old growth resists wildfire and flooding (10). Despite increased biomass, old growth burns less, due to buffered air temperature, stored moisture and structure that resists wildfire. Hydrology changes following harvest. Harvested stands are more vulnerable to the changed precipitation patterns, including intense storm events and droughts driven by climate change.
    Intact primary forests maintain biodiversity and provide a suite of ecosystem services (11). These forests are critical for biodiversity, ecological integrity and services people need and care about.
    Old growth provides wildlife habitat. Intact forest at multiple scales supports population growth and dispersal and provides climate refugia.
    Intact forest buffers water flow and temperature. Forests act as sponges, releasing water slowly to buffer extreme low flows. They also shade streams from increased air temperature, protecting sensitive fish.
    Policy Rationale:
    Works towards international protected area agreements and federal commitments to 30% by 2030. Currently BC is not meeting agreements to protect 17% of representative terrestrial ecosystems.
    BC has a global responsibility for biodiversity and carbon, particularly because of its rare and productive coastal and inland temperate rainforests.
    Implements the Old Growth Panel recommendations as specified in mandate letter.
    Addresses multiple foundational principles and directives in mandate letters.
    Supporting Actions
    Supporting actions to increase forest protection include the following:
    Shift paradigm from timber to ecological integrity (i.e., implement Old Growth Panel recommendation #2);
    Change legal requirements to remove “without unduly impacting timber supply” clause (i.e., complete FRPA update #2).
    Implement Old Growth Panel recommendations in their entirety;
    Update carbon accounting to properly value storage in old forest as compared with validated managed stand contributions;
    Increase conservation and wildlife habitat protection in land use plans;
    Conservation science knows how much of each representative ecosystem to retain in order to have a high probability of maintaining ecological function.
    Empower First Nations to develop interim moratoria on timber harvest in their traditional territories to evaluate ecological and cultural values, and ensure collaboration.
    Emphasize long-term sustainability for communities by shifting the reliance on limited primary forest that will be gone within a decade.
    Land-use planning provides the regional-scale mechanism to increase protection of primary forest. Here are a few models.
    Omineca Environmental Stewardship Initiative. Carrier Sekani First Nations and the Province have mapped biodiversity management areas for conservation. These agreed-upon areas should have been included in the government’s deferral areas.
    Gitanyow Land Use Plan. This plan, which increased conservation for biodiversity, cultural values and water management, has been incorporated into legal objectives. Gitanyow asked the province to decrease the AAC on their territory because modeling shows it is not sustainable from an economic perspective (let alone ecological). The province has not yet agreed.
    Great Bear Rainforest. Many complexities here. A better process and targets than most other plans, but implementation remains a challenge as industry still high-grades the biggest trees.
    Clayoquot Sound Scientific Panel. The province’s first collaborative science/traditional ecological knowledge panel with recommendations accepted by the province.
    Additional Suggestions
    Increase in-stand retention to increase the probability of maintaining biodiversity and ecosystem function.
    Addresses biodiversity, climate mitigation, refugia, wildlife, water protection
    The science is well developed, with regional examples (e.g., Date Creek Research Forest in Kispiox Valley)
    Increase diversity in tree species to address uncertainty and climate change.
    Challenge: optimistic models overestimate timber supply
    BC’s timber supply has reached its fall-down and rural communities are in crisis. Using optimistic models to set allowable annual cut levels has driven forest management in perverse directions, leading to over-harvest, community instability and biodiversity declines. Growth and yield models have overestimated stand growth, by underestimating the effects of natural disturbances and ignoring climate change. This optimism, coupled with a lack of monitoring and operational scale model validation that could have corrected course, has led to unsustainable harvest rates.
    In many parts of BC, little old growth remains available for harvest. This timber supply fall-down has been anticipated for decades, but not addressed. Because harvest focused on productive stands, what remains often has low volumes and high costs, which exposed many BC mills to collapse and shutdown when lumber prices fell in 2019. A long-term future for communities can only be based on diverse rural economies that meet the global demand for low-carbon products rather than focusing on high-carbon resource extraction.
    Suggestion: develop a realistic annual allowable cut
    A realistic allowable annual cut (AAC) is a prerequisite for a strong sustainable economy, for environmental sustainability, for reconciliation and for fighting climate change.
    Use a realistic approach to model timber supply that includes current science on growth rates, disturbance and mortality. Update models based on improved inventory and extensive monitoring of stand health and growth.
    Account for climate change in models. Future tree mortality will increase due to increased drought, wildfire and storm disturbance, insect outbreaks and pathogens.
    Expand inventory to validate and calibrate models. Base harvest levels on inventory and monitoring rather than uncertain forecasts.
    Ensure that high productivity sites are not preferentially harvested; do not leave only high-cost, low-value forests for future generations.
    Quebec forestry has changed from using simulation models to set AAC (as BC does now) to using inventory plots to monitor growth rates and help set AAC level. This seems to be a positive change.
    Gitanyow Hereditary Chiefs have conducted an independent timber supply review on their territory that considers the best knowledge about mortality and growth, and incorporates climate impacts. The methods estimate the probability of different harvest levels being sustainable and allow determination of a sustainable AAC based on risk tolerance. To date, the province is considering their input, but has not changed the AAC.
    Challenge: short-term economics vs. resource-dependent communities
    The industrial status-quo threatens rural communities. Many rural communities in BC depend upon resource extraction for jobs. Over recent decades, many mills have closed and forest jobs have declined as large corporate industry works to maximize short-term profit and invest profits in mills elsewhere while liquidating BC’s old growth.
    The current model puts industrial timber economics above local economies and employment as well as above community health (e.g., clean water, clean air, recreation and spiritual experiences). Foresters face a conflict of interest when managing forest tenures directly tied to mills that are linked to corporations and shareholders.
    Economic and productive systems need to be transformed to power the shift to sustainability.
    Suggestion: tenure reform
    Reform the forest tenure system to reduce emphasis on an oligopoly of multinational corporations and place control in collaborative organizations that embrace sustainability and indigenous rights. For example, regional forest trusts and community governance bodies can determine important values (such as ecological sustainability, clean water, diversity of jobs), acceptable risk levels, and suitable harvest amounts and patterns. Timber companies can then design logging plans or bid on open log markets and focus on manufacturing, where their expertise lies, rather than on forest management.
    Regional log markets provide timber to small manufacturers.
    Local residents find jobs in forest trusts or community-based authorities and manufacturing.
    The traditional business model of forest companies no longer applies; new models have little to do with sustainability and much to do with highly mobile transboundary capital, lowest cost investment and little place-based accountability.
    Changing tenure provides opportunities for ENGOs such as The Nature Conservancy to manage and/or purchase and protect land.
    Community forests and First Nations’ woodland licences in BC have a variety of management approaches. Some are focused on providing economic benefit to communities; many aim to achieve sustainable management certification.
    The Algonquin Forest Authority provides a business structure model that manages landscape as a public tenure ownership.
    Quebec forestry has shifted from industrial to government control of forest management. This has had unexpected consequences, with government foresters less inclined to follow outside recommendations; perhaps a mixed model might be best.
    The First Nations owned Menominee Forest in Wisconsin has been sustainably harvested for more than 150 years, prioritising removal of low-quality trees and keeping vigorous trees, guided by ecology but still highly profitable.
    Wildwood Ecoforestry Institute Society on Vancouver Island has continued Merv Wilkinson’s legacy of ecologically and economically sustainable forestry.

    6. Primary forest is forest of any age that has not been disturbed by industrial activities. Not all primary forest is old, but all old growth is primary forest. Old growth forest reflects a landscape’s natural disturbance regime. In wet regions, where disturbance is rare, old growth forest replaces itself over time as small gaps open and fill, providing a complex, dynamically stable environment for centuries. Where disturbances are more frequent, old growth forest is more uniform, with veteran trees representing legacies of past disturbance.

Land use strategies to mitigate climate change in carbon dense temperate forests. Proceedings of the National Academy of Sciences, 115(14), 3663-3668. “Here, we demonstrate this approach in a high biomass region, and found that reforestation, afforestation, lengthened harvest cycles on private lands, and restricting harvest on public lands increased net ecosystem carbon balance by 56% by 2100, with the latter two actions contributing the most. Forest sector emissions tracked with our life cycle assessment model decreased by 17%, partially meeting emissions reduction goals. Harvest residue bioenergy use did not reduce short-term emissions. Cobenefits include increased water availability and biodiversity of forest species. Our improved analysis framework can be used in other temperate regions.”
