Tree survey finds fewer acres damaged by drought, disease, pests and storms An Oregon Department of Forestry aerial survey indicates Oregon tree health improved in 2025, with a slight dip in acres showing death and damage due to drought, disease, pests and storms. The U.S. Forest Service helped conduct the survey, which showed damage of some kind, excluding wildfires, to 181,500 acres, or roughly 0.7% of Oregon’s 30 million acres of forestland. That compares to the 0.8% mark in 2024 and was well below the 1.8% from 2022, the peak during the past decade. Experts cautioned against taking encouragement from the results, however, as the state faces a warmer and drier environment in the long run. “Conditions are intensifying and there will only be improvement on stands where landowners are applying proactive climate-adapted management,” ODF entomologist Christine Buhl said. Strategies include lowering competition for moisture by thinning and weed control, as well as growing the right species for the shifting climate, she added. The U.S. West is experiencing its driest 25-year period in the past 1,000 years, according to the survey report. While 2025 was better than average for the past decade, drought remains...

NEVADA COUNTY, Calif. — Nevada County community members are invited to attend the “Hard Choices in the Woods: Forests, Fire and Herbicide” Town Hall on forest health and vegetation management tools used to reduce wildfire risk in Nevada County. The Town Hall will be held from 5:30 to 7 p.m. Thursday, Aug. 27, at the Miners Foundry Cultural Center, 325 Spring St., Nevada City. Local organizations and agencies will discuss forest management practices used to improve forest health, reduce wildfire risk, and support safer evacuations across the county. These entities are actively implementing work and bring unique perspective to why different treatments are used, what they accomplish and what their limitations are. “The consequences of catastrophic fire are not new to this community. In the race to rebalance the health of our forests before another disaster, we need to use a variety of available tools. While recognizing that none of them are perfect, understanding the benefits, risks, and unknowns for all the tools we have is crucial to understanding how forest health management decisions are made and implemented,” said Aaron Zettler-Mann, SYRCL Executive Director. Panelists at the Town Hall are engaged in regional implementation projects ranging from work at the...
