On a summer morning, Mark Schulze cranes his neck to inspect the canopies of several large trees in the H.J. Andrews Experimental Forest. Though the trunks are charred black, the branches near the crowns are still green. …This experimental forest straddles 1600 acres in the Willamette National Forest about 50 miles east of Eugene, Oregon. Schulze, who serves as the forest’s director, has lived onsite for 18 years. …The Lookout fire started on August 5 when lightning struck a tree on Lookout Mountain, near the experimental forest’s eastern edge. …The fire, though traumatic, presented an incredible opportunity to study the effects of a major disturbance on the forest ecosystem. …Now, some are worried that the Trump administration is putting this work in jeopardy. A reorganization of the Forest Service, reduced levels of staffing, and lapses in federal funding could affect decades of long-term research conducted here and elsewhere.
