The emerald ash borer is a forester’s nightmare: the much detested insect was first detected in 2002 and has since felled over 100 million ash trees.  Aside from the obvious damage and injuries caused by falling trees, the barren streets and parks have been linked to a more long-term problem: higher rates of death from...

Mountain pine beetles have destroyed millions of acres of forest in the Rocky Mountain West.  The marred wood left behind is difficult to clear, creating safety risks such as fire hazards.  However, designers in Colorado and Montana are finding new ways to use this excess pine.

In the late 1800s, 25% of hardwood trees in North America’s eastern forest were American chestnuts. 40 meters high and 2 meters across, they provided abundant resources for both people and wildlife in the form of food, shelter, and building materials. Lightweight, rot-resistant, straight-grained and easy to work with, ...
