To put a rough number on the challenge, the task force plugged in U.S. Forest Service data with estimates that include the size of trees and the stocking levels, a relative way to measure growth potential on an acre. An overstocked stand, for instance, is too crowded to encourage mature tree growth and maximize carbon storage. The task force estimated that better management on 1.5 million acres could increase storage by 20 percent over current levels, although the transition could take 30 years.
Reaching out to this group will require dedicated, boots-on-the-ground landowner education, the task force concluded. It suggested hiring a forest carbon specialist to help coordinate technical assistance within the Maine Forest Service.
There s a lot of interest, said Tom Doak, executive director of Maine Woodland Owners, a statewide member group. The vast majority of landowners know the climate is changing. They see it on their properties, whether it s ticks or trees leafing out earlier.
Doak, who serves on the state task force and is a former Maine Forest Service director, said the advanced age of many owners and pending turnover present new possibilities.
There s a next generation of landowners that s coming on rapidly, he said. There s an opportunity to talk to these folks about carbon.
But whether and how to manage forestland often comes down to money.

Money is not a big motivator for Marple, a retired hospital executive, to better manage his land. He and his wife, Marianne, aren t dependent on income from their woodlot.
The couple cultivates 30 acres of blueberries on their High Meadow Farm, an award-winning family agriculture operation set amid rolling hills east of Gardiner. The small hardwood trees that Marple thins to improve his stands become firewood to help heat the farmhouse. Fir and spruce boughs he culls get piled up in the woods for wildlife habitat.
But as the task force noted, roughly a third of Maine family woodland owners do see their trees as an important economic asset. Roughly 14 percent of them harvest as a supplemental source of income.
The task force also highlighted the need to identify markets that can use low-grade wood, the small trees thinned to make way for more-robust growth. Those markets can provide owners with a financial incentive not to sell their land for other uses.
The draft report didn t get into it, but Maine s markets for lower-grade wood have been battered in recent years.
Six mills that produced pulp or paper in Maine closed over the past two decades. The 2020 explosion involving a key piece of equipment at a mill in Jay erased another market for low-grade pulpwood. At the same time, biomass plants that burn low-grade wood to make electricity have closed or cut back production in the face of natural gas prices and stricter regulations.
One encouraging trend may offer financial rewards for woodland owners who up their storage game: carbon offsets. Markets are evolving in which landowners earn credits for the carbon they store, which are then purchased by corporations and other greenhouse gas emitters to offset their own emissions.
Maine has 15 or so carbon market projects underway. But the rules around those markets are complicated and cost-prohibitive, especially for most small, private landowners. Doak s organization is exploring the potential of grouping together small parcels to participate in carbon offsets. The task force notes that its co-chairs have been in contact with colleagues in other Northeast states about the potential for a regional forest carbon market.

FOREST INDUSTRY BUY-IN REQUIRED
The task force also recommends exploring partnerships with large owners, such as those involved with the Forest Carbon for Commercial Landowners. That group s buy-in is pivotal to any hope of moving the needle on carbon storage. The reason is obvious – they own and actively manage 10 million acres.
Our group is intentionally focused on large commercial forests because of the economics of scale, according to Hagan, the study group s chairman, and because, to date, the existing carbon markets have only enrolled about 3.5 percent of this commercial forestland base.
Hagan s group includes representatives from Irving Woodlands, Baskahegan Co., Wagner Forest Management, The Nature Conservancy and the University of Maine. It s exploring what large owners could do differently to store more carbon while maintaining economic harvest rates. The exercise involves complex computer modeling. Results aren t expected until later this fall.
If we figure out that we can accelerate carbon storage in the forest and in forest products, such as dimensional lumber, then we hope to create incentives for forest landowners to change their management strategies, Hagan said.
Those incentives could range from tax policy to carbon-offset markets, but they are sure to revolve around money and returns on investment.
As a society, we want all sorts of things from our forests, said Alec Giffin, senior forest science and policy fellow at the New England Forestry Foundation. But the only thing we pay for is timber. The question is, do we as a society want to compensate landowners for practicing climate-friendly management?
It s a big question, according to Giffin, a former Maine Forest Service director who s participating in both the large landowner and state task force efforts. Maine has too many trees per acre, he said. Millions of acres need so-called improvement cuts to cull the small, low-value trees and encourage optimum stocking levels. The biggest opportunities lie in the vast northern commercial forests, Giffin said, which have low stocking levels but active, engaged management.
Commercial landowners could grow more wood and store more carbon, agreed Tom Colgan, chairman and chief executive at Wagner Forest Management. The company manages 900,000 acres in Maine, and Colgan is working on the research project with Hagan.
But supply already exceeds demand, Colgan noted, primarily due to the recent market declines. So outside of offsets, there s no financial reason to grow more wood. And even if demand picks up, pre-commercial thinning – the practice of culling small trees to increase spacing – involves time and money.
It costs money for a return that won t come back until 30 to 40 years later, he said.

As the forest carbon efforts proceed, one dilemma is clear: Climate change is an urgent threat, but growing trees takes time.
Marple has contemplated this quandary on his land. He knows the giant red oak standing at the edge of his farm field sequesters a lot of carbon over time. But he wonders about which trees can store it more quickly. That calculus informs the trees he thins and the 40 or so new trees he planted this year on his property, including bur oak, which may be more drought-resistant in a warming world.
Marple takes a holistic approach to cutting carbon, for today and tomorrow. He s reducing the farm s footprint with solar-electric panels and a plug-in hybrid car.
At 74, Marple also takes the long view. Next to the farmhouse is a large sugar maple he planted in the 1980s. Along the road, he recently added four sugar maple saplings for the next generation.
I have three granddaughters, he said. I m worried about them.
