The Clatsop County board passed a resolution urging the Oregon Department of Forestry to preserve a 152-foot tall Western red cedar as a state treasure.
The tree is estimated to be more than 800 years old. It grows on a 286-acre parcel of state land near Cannon Beach.
The Daily Astorian reports the resolution Wednesday asks that the parcel be designated as a high-value conservation area.
Astoria District Forester Tom Savage says the land is already designated as a marbled murrelet management area, and any landowner has to comply with Endangered Species Act protections for the seabird that nests in old-growth trees.
