At the same time, wood—in its “original” state as trees—has been adversely affected by global climate change and other environmental factors. This has led to wildfires of unprecedented fury and reach, including the megagires in Australia in 2009 that generated an inferno of hellish proportions, eventually covering more than 100 million acres. What comes across most vividly in this panoramic study of wood is Roland Ennos’s love of the subject.

Native peoples reintroduced fading species, restored habitats and stopped big industry in its tracks. Several species began coming back, many of them thanks to the efforts of tribal programs. Northwest tribes were pleased to see a record return of Chinook salmon to the Columbia River. A healthy wolf population flourished in Yellowstone National Park, strengthening the wildlife web around it. Here are some of the more notable wins, and the tribes involved in making them happen.

Arditi wants to infuse the future of visual art with the power of its primitive past. “I want to be as close as possible to what art started as, but with a modern twist,” he said when I visited his studio this month. He pulls pigments from natural sources like flowers, rocks, dirt, soil, clay, crystals — anything earth-produced that has a distinct color.
