For over 20 years, tree-sitters in Northern California have taken a stand for ancient redwoods by camping in their branches and acting as physical barriers to logging. But for now at least, the last trees-sitters have all descended from their perches, thanks to a promise from a timber company that owns huge swaths of redwoods in the area. Pacific Lumber, the largest private owner of old-growth redwoods anywhere, had long been a villain to environmentalists since it was acquired by an especially logging-happy investor in 1986 who quickly stepped up logging of old-growth trees. The company has since gone bankrupt and is now under new ownership as Humboldt Redwood Co.; HRC has promised to avoid clear-cutting and to leave any trees standing that are at least four feet in diameter and at least 200 years old. Before the company’s change of heart, though, the threat to ancient redwoods drew in forest activists from across the country who staged regular protests and engaged in direct action to block logging roads so the trees would still be standing by the time a deal was reached to save them.
