Ponderosa pine trees dominate parts of Eastern Oregon and Washington and have long been an icon of the American West, but in the past decade more than 200 million ponderosa have died. Particularly in the Southwest, scientists estimate that by mid-century less than 5% of the ponderosa trees may remain. Portland author Gary Ferguson explores the history and the future of the ponderosa forests of the Southwest in his newest book, “The Twilight Forest.”
