In 2024, the Washington State Department of Natural Resources conducted an aerial survey of its forests, finding that more than half a million acres of trees across the state were sick, stressed, or already dead. While the 545,000 acres affected by tree mortality, defoliation, or disease comprise less than 1% of the forestland surveyed, the count shows an increase of nearly 30,000 acres from 2023 and exceeds the ten-year average of 519,000 acres.
