Residents Fight US Forest Service Over Weed Killer Plan
18 Jun
Summary
- US Forest Service plans to use glyphosate herbicide for post-fire restoration.
- Lake Tahoe residents express strong opposition due to health and water concerns.
- Herbicide use is proposed for areas near the lake and ski resorts.
The US Forest Service has proposed using herbicides, notably glyphosate, to restore national forest lands damaged by the 2021 Caldor fire. This plan aims to clear vegetation before new tree plantings and manage regrowth, with approximately 2,400 to 3,600 acres potentially treated. The proposed spraying is targeted for areas within the Lake Tahoe basin, including regions near popular ski resorts and those whose snowmelt feeds directly into the lake.
However, the plan has ignited fierce opposition from Lake Tahoe residents and local officials. Concerns are primarily focused on the potential health risks associated with glyphosate, a chemical classified as a probable human carcinogen by WHO experts, and its possible adverse effects on endangered species and water quality. A town hall meeting on June 11, 2026, was held to organize resistance against the Forest Service's proposal.
Local authorities, including the Tahoe Regional Planning Agency (TRPA) and the mayor of South Lake Tahoe, have voiced strong opposition and are urging the Forest Service to minimize or prohibit herbicide use. Despite the agency's assurances that herbicides are registered with regulators and deemed the best tools for forest health, community members remain unconvinced, emphasizing the pristine nature of Lake Tahoe and the risks posed by chemical contamination.
