A new wave of forest loss is underway in New England, at a rate of 65 acres a day. That's the conclusion of spearheaded by a Harvard University forest research group. And the authors say New England could lose more than a million acres of forest cover over the next half-century.
When Paul Hunt heads out into Sebago Lake, he sees a handful of cottages here and there along the shore, but mostly it鈥檚 the green cover of a 280,000-acre watershed. Or as Hunt sees it, a vast, natural filtration system for the lake, which supplies drinking water for more than 200,000 people in southern Maine.
鈥淎lmost every other water supply in the country that uses a lake or a river is legally required to filter the water and then disinfect it,鈥 says Hunt, environmental services manager for the Portland Water District. 鈥淭here are about 50 in the country 鈥 and this is one of them 鈥 that the water is so clean that it doesn鈥檛 require filtration.鈥
The water that feeds the trillion-gallon lake follows an ancient glacial path that starts a few miles below the Sunday River ski area. And thanks to good stewardship by landowners along that 50-mile riverway, Hunt says, the watershed has retained and even bettered its purifying capacities over the last century.
鈥淭hat鈥檚 the good news. The bad news is 91 percent of that land is privately owned, meaning it could be converted to nonforest uses whenever the owners make that decision. It鈥檚 their land,鈥 he says.

And the risk of forest loss is rising throughout New England, according to a new report from researchers associated with the Harvard Forest in Petersham, Massachusetts.
The report notes that before the end of the 20th century, much of the forestland razed in New England during its agrarian heyday had been reclaimed. But the authors also found that since the 1980s, New England鈥檚 farming economy stabilized, and with development continuing apace, the forest cover trend line started heading back down.
鈥淚t鈥檚 a drip, drip, drip, and it amounts to 24,000 acres a year. So over time it really begins to change the character of the land,鈥 says Robert Perschel, one of the report鈥檚 authors and executive director of the New England Forestry Foundation.
Perschel says each of the six states is losing forest each year to housing, businesses, parking lots and roads. The losses range from a low of 800 acres as year in Rhode Island to a high of 7,000 in Massachusetts. If that pace continues, New England will lose 1.2 million acres of forest cover over the next 40 years.
He says soil quality, water quality, wildlife habitat and woodland jobs are all at risk.
鈥淓ach New England state is now in a downward trend of forest cover,鈥 Perschel says. 鈥淭hat鈥檚 alarming because New Englanders love their forest, we get a lot of benefits from our forest and if we don鈥檛 do something about it, it鈥檚 going to continue to erode over time.鈥

The report finds that since the 2000s, the number of forested acres protected each year by fee or easement has fallen substantially, while annual federal and state funding for conservation has been halved. The authors say it鈥檚 time to recommit to conservation, calling for some 70 percent of the New England landscape to be protected forest by the year 2060.
Here in Maine, which is home to more than half the region鈥檚 forested acres, the protection goals can make people like Patrick Strauch, executive director of the Maine Forest Products Council, a bit wary.
鈥淚 want to be arguing for forest management and being concerned about development. But I also live and work in these rural areas of Maine,鈥 he says. 鈥淚 wouldn鈥檛 mind a little development in some of these rural areas of Maine.鈥
The report鈥檚 authors say they don鈥檛 want to lock up New England鈥檚 forests. Although they call for preservation of 3 million acres in a wild state, the remaining 27 million acres would be barred to development, but still open for forestry, recreation and other economic activities.
