The following document was prepared by the Yankee Division of the Society of American Foresters (SAF) in 2020, in response to public sentiment and misinformation suggesting that the cutting of trees was not in keeping with goals of mitigating climate change and sequestering/storing terrestrial carbon. Sounds forestry practices are in fact some of the best tools we have to maintain healthy forests and their function as mitigators of the impacts of climate change and collectors of carbon. It is also the means by which we can preserve biodiversity and provide sustainable and renewable products (timber, maple syrup, etc.) while also meeting carbon and climate goals.

The entirety of SAF has gone on to adopt similar positions, as collected on their website.

Southern New England Forest Management in an Era of Climate Change
A Position prepared by the Yankee Division of the Society of American Foresters

Purpose: This document reports the best available scientific findings and management strategies related to forests and carbon sequestration and storage in southern New England. This information will help guide development of public policy for forest management in this region. Forests are central to our history, identity and way of life. The forests of southern New England provide critical ecosystem services including water quality, biodiversity, carbon sequestration and storage, recreation, and human health, important products, and productive employment, while providing solace and sense of place. Climate change, coupled with New England’s land use history and increasing human population, has heightened the need to responsibly manage these forests for multiple uses including sequestration and storage of atmospheric carbon.
Scope: This statement outlines the ways in which a spectrum of forest stewardship strategies in southern New England contribute to climate change mitigation and adaptation, provide services and products for society, and sustain resilient forests for future generations.

Position
It is the position of the Yankee Division of the Society of American Foresters (Yankee SAF) that active forest management, grounded in science, is essential to maintaining and promoting resiliency and ecosystem services. Such management will:
1) Promote carbon sequestration and storage (Evans and Perschel 2009, McGarvey et al. 2015);
2) Provide additional ecosystem services including air and water pollution mitigation (Cardinale et al. 2012);
3) Provide locally sourced and sustainable wood products that substitute for more carbon intensive materials (e.g., wood instead of concrete, biomass fuels instead of fossil fuels) (Rudell et al. 2007);
4) Reduce forest fragmentation, mismanagement, and conversion to non-forest both locally and globally; and
5) Improve biodiversity and the capacity of ecosystems in southern New England to withstand and adapt to the impacts of climate change.

Issue
The issue of forests and carbon is complex and increasingly important. Carbon uptake (i.e., sequestration) occurs in growing forests, generally peaking in early stand development, but sometimes continuing at high rates through late-successional stages, particularly in structurally complex forest systems (Bormann and Likens 1979, Keeton et al. 2007, Keeton et al. 2011). Carbon storage occurs in the biomass of forested systems and in long-lasting wood products, such as lumber.
Wood products store carbon and help to offset the need for extraction and production of non-renewable, carbon-intensive materials, such as concrete, steel and petroleum-based plastics. Locally and regionally produced wood products have a relatively smaller carbon footprint due to lower transportation costs and are sourced from well-regulated forests (Kittredge et al 2002, Ashton et al. 2012).
Forest management, including timber harvesting, is consistent with goals of promoting long-term carbon sequestration and storage. Management practices continue to adapt as we gain a better understanding of the relationships between forestry and atmospheric carbon. Reducing harvest frequency and favoring high levels of structural retention, for example, can sequester up to 57% more carbon (Nunery and Keeton 2010). Reforestation also increases carbon sequestration (Rhemtulla et al. 2009). In urban areas this would also improve quality of life through other ecosystem services (Nowak and Greenfield 2008). Managing for a variety of values and uses on a long-term timescale using peer-reviewed forest science and a holistic understanding of the forest systems ensures that southern New England forests continue to capture and store carbon, maintain ecosystem functions and services, and decrease global deforestation and fossil fuel use. While reserve-based management is appropriate in some places, sustainable timber harvesting in most forests best serves human needs in the long term. Meeting these objectives will require a full suite of conservation strategies working together, including both sustainable harvesting and reserve-based management (Foster et al. 2017).

Background
The Importance of Forests
Forests are central to our history, identity, and way of life. The health of our forests will strongly influence our collective future. Forests renew the air we breathe and filter the water we drink. We rely on forests for a host of renewable raw materials for products from maple syrup and medicinal plants to fuel and lumber. Forests provide habitat to wildlife, beneficial insects and plant species. Forests prevent erosion, build soil, store nutrients, and sequester and store carbon. Forests also provide the joy of birdsong, inspiration, and renewal of spirit.
Forest Disturbance and the Need for Resilience
Disturbances play an important role in structuring the forested landscape and are vital for functions including regeneration. Disturbances range in type, size, frequency and intensity (Turner et al. 1998, Lorimer and White 2003). Variation in post-disturbance abundance and spatial arrangement of live and dead trees impacts species composition and carbon storage dynamics (Franklin et al. 2002, Seymour et al. 2002, Birdsey 2019).
While the most common natural disturbances in Southern New England forests are wind and ice storms, impacts of invasive insects and fungal diseases are increasing. Fire as a disturbance has only recently declined and could become influential again. Fire has a long and varied history in New England with its frequency, intensity, severity, and extent heavily influenced by changes in land use practices (Patterson and Sassaman 1988, Brose et al. 2014, Lorimer and White 2003, Hurteau et al. 2011, Janowiak et al. 2014). Anthropogenic disturbance (e.g., harvesting and silvicultural action) has also been an influential driver of forest condition, and response to decades of forest management is one of the largest factors shaping current forest conditions (Duveneck et al. 2017).
Climate change in the Northeast is altering ecosystem disturbance regimes (Evans and Perschel 2009). Changes vary seasonally and include increases to average temperatures, heavy precipitation events and drought, and decreases in snowfall and snowpack (Janowiak et al. 2018). Forest composition and condition models show varying responses to changes in climate and natural disturbance regimes (Tang and Beckage, 2010, Rustad et al., 2012). The impacts may happen at such a rate that the recovery of the forest ecosystem cannot keep pace (Liang et al., 2017), or cause substantial loss of species richness and diversity (Iverson and Prasad, 2001). At the same time, the landscape is facing loss of forests through conversion to other land uses (Kittredge, 2009, Olofsson et al. 2016).
Resiliency – a forest’s capacity to recover function after a disturbance – is critically important for sustaining forest ecosystems in this era of rapidly changing climatic conditions. Resiliency enables the forest to maintain, restore or enhance ecosystem services, including carbon sequestration and storage, following disturbances. Informed forest management and protection of forestland from development provides the opportunity to maintain or improve resiliency by retaining connectivity, increasing complexity and maintaining or enhancing diversity across forested landscapes (Catanzaro and D’Amato, 2019).
Forest Carbon
Forested ecosystems provide a valuable ecosystem service by storing and sequestering carbon, reducing atmospheric CO2. Temperate forest ecosystems have been widely acknowledged as a carbon sink (Ashton et al. 2012); U.S. terrestrial forests offset ten to thirty percent of annual U.S. CO2 emissions (Houghton 2003).
Trees and forest vegetation sequester carbon from the atmosphere through the process of photosynthesis. Carbon is stored in various pools including live and dead aboveground biomass, belowground biomass, woody material and leaf litter, and soil (Fahey et al., 2005; Catanzaro and D’Amato, 2019). Amounts of sequestered and stored carbon are dynamic – constantly fluxing between and within pools as forests and land-use change over time. Decades of research illuminate the variety of factors driving forest carbon sequestration and storage dynamics. Stand age is strongly predictive of aboveground biomass in the northeastern U.S., with other variables, including ecoregion and conifer composition, accounting for 25-33% of variability (Keeton et al. 2011). Disturbance, both natural and anthropogenic, is also a driving factor of carbon sequestration and storage dynamics (Birdsey et al. 1997, Duveneck et al. 2017).
Reports of carbon sequestration and storage vary widely due to these factors. In the Northeast, biomass (i.e., stored carbon) generally increases over time (Barford et al. 2001, Hadley and Schedlbauer 2002, Keeton et al. 2011), but can exhibit decline in different stand conditions or due to stressors (Fahey et al. 2005).
The rate in forest carbon uptake (i.e., sequestration) in the Northeast is declining (Birdsey et al. 2019), as has been observed in maturing forests (Bormann and Likens 1979, Keeton et al. 2007). However, managing for complex forest structure, as often found in primary and mature or old-growth secondary forests, can yield an increase or maintenance in net carbon sequestration (Luyssaert et al. 2008, Nunery and Keeton 2010).
The carbon stored in wood products adds to the complexity of carbon accounting. Hardwood flooring, dimension lumber, and plywood are forms of stored carbon and should be accounted for as such. Furthermore, the use of these products avoids carbon emissions from the extraction and production of more carbon-intensive materials such as vinyl, carpet, concrete, and steel (Oliver et al. 2014). Wood utilization and technology continue to improve the production of wood products and increase associated carbon storage (Tollefson 2017). Cross-laminated timber (CLT) is capable of replacing concrete for multi-story buildings (Robertson et al. 2012). A life cycle assessment of the four-story John W. Olver building at the University of Massachusetts found that the use of CLT and other wood products instead of concrete and steel reduced the building’s global warming potential by 13% (Gu and Bergman 2018). Substituting wood for steel and concrete in new buildings world-wide would reduce global CO2 emissions by 14 to 31% (Oliver 2014) and interest in this technology is rising (Struck 2019).
Sequestration in the forest and carbon emission offsets associated with wood products from sustainable forest management are critical components of carbon management. Research continues to increase our understanding and must guide forest practitioners to improving the capacity of this vital resource.

Sustainable Forest Management and Timber Harvesting
Sustainable forest management is a “dynamic and evolving concept, which aims to maintain and enhance the economic, social and environmental values of all types of forests, for the benefit of present and future generations” (FAO 2020). Yankee SAF strongly supports the practice of sustainable forest management that includes both limited reserves and responsible harvesting as the best way to ensure that forests continue to provide a wide array of benefits. FAO lists the following climate change mitigation and adaptation actions for forests:
 Carbon sequestration enhancement by silvicultural practices
 Carbon stock conservation by preventing deforestation, implementing reduced impact logging, and pest control
 Substitution of wood products for steel, concrete, aluminum, and plastic
 Reducing the vulnerability and strengthening the adaptive capacity of trees and forests.
Sustainable forest management can accelerate development of complex structure in northeastern U.S. forests (Keeton 2006), making it possible for early successional canopies to support the complex functioning and biodiversity seen in late-successional or old-growth forests (Donato et al. 2012). Reducing harvesting frequency (Curtis 1997), increasing rotation lengths (Harmon and Marks 2002, Ryan et al. 2010), and encouraging post-harvest structural complexity (Keeton 2006, Franklin et al. 2007, Swanson 2009, Puettmann et al. 2009) have been found to increase stand-level carbon storage. Maintaining adequate stocking of large trees (Stephenson et al. 2014), while also allocating growing space for younger trees can promote higher rates of stand-level carbon storage and sequestration (D’Amato et al. 2011). These practices can also strengthen forest resiliency. Each parcel’s unique species composition, forest structure, and landscape position must be evaluated to determine its vulnerability to disturbance and its role in benefiting present and future generations.
Sustainable forest management promotes diversity of species, ages, sizes, and spacing of trees, improving overall forest resilience. A gypsy moth outbreak that kills large oak trees will not harm tulip trees. A hurricane or tornado may flatten mature trees and not damage saplings that bend more readily. A drought can weaken or kill overcrowded trees but has less impact on trees freed from competition through active management.
Managing forests to promote resiliency and greater carbon storage is stand-specific. Sustainable forest management considers many different tree and site characteristics to determine the most suitable actions to meet the goals of forest management. The effects of certain management prescriptions on carbon sequestration and storage, for example, are dependent on stand age characteristics. Reducing harvest frequency more effectively increases carbon sequestration in uneven-aged New England stands than in even-aged stands (Nunery and Keeton 2010). Retaining such biological legacies as large old trees also promotes diversity by sustaining many organisms and critical ecosystem functions, such as soil stabilization, nutrient retention and recycling, and resilience to disturbance (Franklin et al. 2007, Hanson et al. 2012). Generally, silvicultural treatments that maintain a large proportion of mature trees maintain or increase aboveground carbon storage (D’Amato et al. 2011).
Sustainable forest management that includes harvesting reduces the volume of dead wood that will release carbon due to decay (Hoover and Stout 2007). The carbon in durable wood products such as plywood, framing, flooring and furniture is stored much longer than the carbon in dead trees (Russell 2014). In southern New England, the volume of wood in trees that die naturally is over three times that contained in harvested trees (Oswalt et al. 2019).
Durable wood products are more carbon-efficient than alternative products, in addition to storing sequestered carbon that would otherwise be released back to the atmosphere through decay. In addition to the benefit from the carbon stored in durable wood products, there is less carbon released from harvesting and manufacturing wood products than from mining non-renewable resources and manufacturing products from them (Bergman et al. 2014). Many studies have documented that one of the key carbon sequestration benefits of active forest management is the substitution of products made from wood for those made from steel, aluminum, or concrete (Oliver 2014, Woodbury and Wightman, 2017).
Forest products are important to our local economy. In 2013, Southern New England’s forest-based economy accounted for an estimated $5.8 billion dollars in gross regional output and provided employment to approximately 28,525 individuals (Northeast State Foresters Association 2015). In addition, revenue generated from the sale of forest products helps encourage keeping forests as forests and limiting their conversion to non-forest uses.
A resilient forested landscape is comprised of a variety of forest conditions. Sustainable harvesting and management to preserve old forests each result in the storage of significant amounts of carbon. Minimally disturbed forests provide critical habitat for some species and are invaluable for scientific research. Forest management that includes harvesting can proactively and intentionally create or enhance habitat for the myriad vertebrate and invertebrate species that depend on young forests or forests with heterogenic structure (DeGraaf and Rudis 1992, DeGraaf et al. 2005). Sustainable forest management that includes harvesting yields additional benefits for useful, renewable products, reduced carbon emissions, and important aspects of resilience that preservation does not.
Resilient, vigorous, functional and diverse forests are critical for continuing our way of life in southern New England. The disturbance regime that our forests experience has changed due to the loss of some species (including apex predators), the introduction of others (especially invasive species), and a changing climate. Sustainable forest management maintains and enhances ecosystem function and resiliency so that the forest resource continues to meet societal needs. Water quality, soil integrity, carbon capture, diverse wildlife habitat, forest products, recreational opportunities, and aesthetic beauty can be maintained or increased. We have the opportunity and the responsibility to be a part of the solution.
