"...Those involved in the project, including high-level state Department of Natural Resources officials, cite a key statistic when they trumpet Mascoma’s promise: Michigan grows about 2.5 times more wood fiber annually than it harvests. But that claim may be misleading.
“It’s a bogus statistic and they’ve been using it for years,” said Anne Woiwode, executive director of the Michigan Sierra Club. According to Woiwode, if that figure is accurate, which many foresters doubt, it would also have to include wood on private lands – lawns, golf courses, parks, small wood lots and preserves...

...One answer is to grow wood quickly. Foresters agreed that a project like Mascoma will pressure forestry planners to concentrate on fast-growing woods and that the state would have to consider “short-rotation energy crops,” such as aspen, poplar and willow.

[When I lived up north near the Straits, my woodsy backyard had some trees the locals called popple. They were so soft, they'd fall over in a breeze. When we cut them up for firewood, they absorbed the rain like sponges and then stank. They were great for making paper. You could crumble a cross-section of the trunk in your bare hands.]

"...The Kinross-based project will draw "feedstock," or wood, from a 150-mile radius. That puts wood in play well below the bridge and far to the west of Newberry..."

[From Kinross to West Branch is about 168 miles.]
