In this Feb. 22, 2017, photo, Ryan Haugo, senior forest ecologist for the Nature Conservancy, describes large trees being left while smaller ones are thinned on a 100-acre patch on private land they own overlooking Cle Elum Lake, in Cle Elum, Wash. As part of a broader plan by the nonprofit environmental group to restore the pine forests of the Central Cascades so they are more resilient to wildfires and climate change, they're cutting down trees to save the forest.
