Spruce at Penobscot

Since 2020, the University of Maine’s Forest Climate Change Initiative (FCCI) has collaborated with the Forest Stewards Guild to address Climate Change impacts in Maine’s forests. They began with a Science and Practice forum in Orono in February 2020, where forest scientists and managers gathered to  identify the highest priority concerns  around climate change in Maine’s forests.   

In the Fall of 2020, the FCCI and Guild kicked off a  monthly webinar series  to catalyze scientist-manager discussions about climate change research, grow Maine’s forest climate adaptation community of practice, and be a resource for the Maine Climate Council about Maine’s forests and climate change. The first season of the Forest Climate Change Science & Practice series featured nine lunch-hour webinars that spanned topics from carbon budgets to forest biodiversity and species shifts. 

Season 2 of the Forest Climate Change Science & Practice took a new approach – coupling lunch hour webinars with follow up field tours. This new hybrid model provided the ideal balance between information sharing and in-depth discussions in the field, with each session focused on a specific forest type in Maine. 

Penobscot Field Tour

Spruce-fir (Inland) at the Penobscot Experimental Forest 

The series’ second season kicked off in October with the spruce-fir (inland) forests at the  Penobscot Experimental Forest (PEF)  in Bradley, Maine. The PEF is a research forest jointly managed by the University of Maine (UMaine) and the United States Forest Service (USFS). This webinar and field tour featured USFS Research Scientist Laura Kenefic, UMaine Forest Manager Keith Kanoti, UMaine wildlife faculty Alessio Mortelliti, and Maine Forest Service (MFS) District Forester Kenny Fergusson. 

During the webinar, participants learned about the decades of research at the PEF. Discussions in the field focused on how different management techniques lead to vastly different results in the woods. The first stop on the tour looked at selection cutting and commercial clearcut, and the discussion focused on how viable each method would be for landowners. At stop two, presenters and participants compared a shelterwood without thinning and with thinning. Here, discussion focused on future forest stand development and what conditions make a forest more resilient to climate change and enhance carbon storage. The tour’s final stop visited a strip clear cut focusing on operations and how adaptability is key to changing winter conditions. 

Holt Field Tour

 Oak-pine at the Holt Research Forest

The series continued in December, focusing on the Holt Research Forest in Arrowsic, Maine. The  Holt Research Forest , owned by the Maine Timber Research & Environmental Education Foundation (Maine TREE), is a long-term forest research and monitoring site, launched in 1983. Two timber harvests have taken place in that time. The most recent occurred one growing season before the tour in the winter of 2020/21. This session featured longtime Holt Research Forest scientist Jack Witham, consulting forester Barrie Brusila, Maine TREE Programs and Outreach Coordinator Kelly French, and MFS District Forester Shane Duigan. 

The webinar featured key findings during the nearly 40-years of continuous monitoring. Findings include the loss of hardwood regeneration due to increased deer browse and oak regeneration patterns linked to masting years. Additionally, the forest experienced shifts in small mammal species, highlighted by the shift from predominantly Northern flying squirrels (  Glaucomys sabrinus  ) to Southern flying squirrels (  Glaucomys volans  ) in the early 2000s. 

The field tour took participants on a loop around the recently harvested research grid. It included stops at unharvested control areas, canopy gaps created during the harvest, a stream crossing location, and a recently installed deer exclosure. The discussions ranged from the effects of deer herbivory on regeneration to the importance of microclimates and climate-adapted plantings. 

Rangley Lakes Field Tour

 Spruce-fir (coastal) at the Schoodic Peninsula  

The third session in February focused on coastal spruce-fir forests on the Schoodic Peninsula . Schoodic Peninsula sits just north of Mount Desert Island and features the only portion of Acadia National Park on the mainland. During this session, participants heard from  Schoodic Institute  President & CEO Nick Fisichelli and Forest Ecology Director Peter Nelson, along with MFS District Forester Michael Jensen, Maine Department of Inland Fisheries & Wildlife (DIFW) Regional Biologist Steve Dunham, and Maine Coast Heritage Trust Project Manager Bob DeForrest. 

Online, the virtual session highlighted Nelson’s work using remote sensing to monitor forest health and wildlife connectivity on the peninsula. In the field, DeForrest led the group along trails of the  Forbes Pond Preserve , a Maine Coast Heritage Trust property on the peninsula, where conversations ranged from silviculture and recreation management to the value of ecological features such as lichen and coarse woody material. After visiting the Preserve, the group made their way to Frazer Point in Acadia National Park, where Fisichelli described the peninsula’s recent history and forest practices. The group then walked through an older spruce-fir forest where the park recently constructed a bike path to increase recreational opportunities. 

Rangeley Lakes Field Tour

Mixed hardwoods in the Rangeley Lakes Regions

In April, the final session of the series focused on mixed hardwood ecosystems in Western Maine’s Rangeley Lakes region. The Rangeley Lakes region is unique for its mixed-hardwood forests and the range of partnerships and ownerships in the region working in concert to steward the forest resource. The session featured  Rangeley Lakes Heritage Trust (RLHT)  staff, including Executive Director David Miller, Deputy & Stewardship Director Shelby Rousseau, and Natural Resource Specialist Jason Latham as well as Christine Parrish and Alec Giffen of the  New England Forestry Foundation , Walker Day of  Seven Islands Land Company , Private Lands Wildlife Biologist Joe Roy for Maine DIFW, and MFS District Forester Julie Davenport. 

To set the stage for the field tour and highlight the partnerships, the webinar emphasized a landscape-level perspective of forest management and conservation in the region before focusing on hardwood management in a changing climate. 

During the final field tour, participants visited the Stephen Phillips Memorial Trust Preserve, managed by the Seven Islands Land Company (who also provides forest management services for RLHT) and under a conservation easement held by RLHT. The Preserve hosts varying stages of hardwood forest development, including recently harvested areas and areas where harvesting hasn’t recently occurred. This property provided a strong example of uneven-aged forest management in hardwood systems. Where harvesting hasn’t taken place recently, discussions focused on managing for diversity and carbon. When visiting the site where harvesting occurred over the winter, conversations shifted to the importance of having a skilled workforce, which was apparent when reviewing the expertly tended stand.

Building a Community of Practice 

Each session provided an opportunity to build the climate change community of practice that convened for the first time at the Science and Practice Forum in 2020. The virtual format adopted at the beginning of the COVID-19 pandemic continued to provide a platform for addressing the science and practice of climate change-related impacts to professionals from every corner of the state. The addition of field tours created a new avenue to develop the community with opportunities for in-depth discussions about the challenges managers face in the woods. The field tours also provided a vehicle for informal conversations and connections while traveling to field sites, and of course, over lunch with friends in the field. 

The varying backgrounds of the participants amplified the benefits of these connections during each session. From government agencies at the federal and state level to conservation nonprofits and land management companies, everyone on the field tours played the role of teacher and student, bringing their unique perspectives to the conversation.

Key Themes

Many subthemes emerged within the primary theme of climate change throughout the series. Each site highlighted the impacts and disturbances such as windthrow, insects and diseases, and other climate-related impacts that influence management decisions. Wildlife also emerged as a key theme throughout the series. Changing forest conditions change how wildlife use the forest, and forest connectivity is essential for providing forest corridors for all types of wildlife. Finally, each session specifically focused on communicating with landowners about climate change. MFS District Foresters joined each panel and field tour to discuss their experience talking with landowners who have climate change on their minds. Engaging landowners is critical to addressing climate change in Maine’s forests at a scale that makes a difference. 

USFS Research Forester, Laura Kenefic, posed the most important consideration during the first session:   “The treatments we visit have varying carbon storage, adaptation, and climate and market resilience outcomes. An approach that is good for one objective is not necessarily good for others. How do we balance these competing demands, and what are the tradeoffs?”   

As it often is in forestry, the answer is:  ‘it depends.’

In September 2025, the Guild launched a three-person Forest Stewards Apprenticeship (FSA) crew to work with the Penobscot Nation’s Department of Natural Resources (PN DNR). Over the course of their six-month season, apprentices Agenor Duhon, Gabe Stewart, and Jacob Baker shared a season of learning, collaboration, and hands-on stewardship of Penobscot Tribal lands.

This week, I stepped into the role of crew leader. We worked a full 40-hour week, splitting our time between Clifton Farms and a prescribed burn operation. On the first day in the field, we completed hack-and-squirt treatments on trees that had been marked the previous week. For the remainder of the week, we focused on marking trees for future hack-and-squirt work, maintaining a steady pace and ensuring accuracy in our selections.

As Guild members, our practice is fundamentally grounded in field observation. We know intuitively that forests are dynamic, living communities. Yet, for decades, the high-level systems used to value our work, specifically the carbon accounting ledgers tied to international frameworks like the Paris Agreement, have treated forests as static, quantifiable blocks of land. In a recent commentary published in One Earth, I argue that these legacy measurement, reporting, and verification (MRV) frameworks are failing. Ledger accounting relies on crude land-use delineations and outdated technology, effectively penalizing the natural, seasonal flux of the ecosystems we manage every day. By forcing landscapes into rigid “forest” versus “non-forest” binaries, such legacy systems miss the complex reality on the ground. But a major shift is underway.

Women have always been a part of forestry. Historically, women often helped guide family decisions about when to cut, which trees to save, and how best to steward their land for the next generation. Historical accounts from the Southern Appalachians describe women’s roles in decisions about timber harvesting and prioritizing long-term forest health. These often-uncredited contributions are even reflected in Aldo Leopold’s A Sand County Almanac (1949), in which describes his stewardship philosophy informed not only by his professional experience, but by shared responsibility, where the perspectives of his wife and daughters played an important role.

The Forest Stewards Guild has been working to support the National Park Service on forest stewardship projects throughout the eastern U.S. This month we are in the midst of a project to protect mounds at Effigy Mounds National Monument near Harpers Ferry Iowa. This site was designated as a National Monument in 1949 and preserves over 200 mounds built between 800 and 2,500 years ago. Mounds at this site include conical, linear, compound, and effigy mounds – constructed in the shape of animals. Please see the National Park Service page for more information about the mounds, the people who built them, and how to visit the site. The lidar images on that website of the Marching Bears and other mound groups are fascinating.
