Dyer's Woad on Grizzly Mountain in the Oregon Gulch fire boundary
The Oregon Gulch fire boundary on Grizzly Mountain at the county line between Jackson and Klamath counties is the epicenter of the Dyer's Woad infestation and if not contained properly, the weed will spread to surrounding public and private lands causing environmental, agricultural, and economic issues. Klamath County lists Dyer’s Woad as an “A” listed noxious weed and the members of the Klamath County Cooperative Weed Management Area are concerned about the infestation spreading from Grizzly Mountain.
The current objective is to retain a boundary by treating roadsides in combination with larger infestations within the area. Public ingress/egress by road increases the risk of the plant spreading beyond the fire boundary.
Klamath SWCD was awarded $15,000 in 2025 to continue this project work.
