HUMBOLDT COUNTY, Calif. (KGO) -- The Humboldt County Sheriff's Office served seven search warrants in the Island Mountain area last week, seizing 23,211 marijuana plants worth approximately $26.5 million.

The search warrants were for commercial marijuana growing operations located in over 40 separate large green house-type structures on the parcels of property, authorities said.

Authorities also seized or eradicated 4,394 pounds of processed marijuana, 15 pounds of marijuana hash in brick form, 16 firearms and 50,000 rounds of ammunition.

Deputies say they are working with the State of California Department of Fish and Wild Life Services in their investigations in identifying the property owners and suspects involved and the environmental damage done on the parcels of property.

These cases are still under investigation by the Humboldt County Sheriff's Office.
