A new analysis reveals that many of Eastern Oregon’s ancient trees are dying at an alarming rate. The study, conducted by a team led by James Johnston, an assistant research professor at the University of Oregon, found that between 2012 and 2023, a quarter of trees over 300 years old in roadless areas of the Malheur National Forest had died. Johnston attributed the decline to a combination of drought, insect infestations, and competition with younger trees. “It’s sad to see so many old trees dying,” Johnston said. He emphasized the need for active management to protect these ancient trees, particularly in the dry forests of Eastern and Southern Oregon. The study, published in the journal Forest Ecology and Management, highlights the importance of old-growth trees, which store carbon, provide critical habitat, and help maintain water quality. Johnston’s research, which began a decade ago, involved taking core samples from old-growth trees in unlogged sections of the forest.
