California Department of Justice spokeswoman Michelle Gregory tells the Press Democrat of Santa Rosa that the raids have netted nearly 300,000 marijuana plants and led to 77 arrests as of Monday, according to The Press Democrat.
Citing officer safety concerns, officials declined to give details of the operation, which began early last week but which they initially attempted to keep secret.
The operation includes hundreds of law enforcement officials from local, state and federal agencies. Raids are taking place simultaneously in Mendocino, Lake, Colusa, Glenn, Tehama, and Trinity counties, counties that contain portions of the Mendocino National Forest.
Each summer law enforcement agencies eradicate millions of pot plants from California public lands, which marijuana growers favor for their remote locations and rugged terrain.
The latest raids span Mendocino, Lake, Colusa, Glenn, Tehama and Trinity counties. Hikers and ranchers report more run-ins with armed pot growers in the region.
