Sacramento, Calif. -

A federal crackdown on marijuana growing in seven western states has uprooted more than 1 million plants, about two-thirds of which were found on public land.

The U.S. attorney's office in Sacramento says the pot found on public lands was worth nearly $1.5 billion. The agency released total figures for the July and August raids in Arizona, California, Idaho, Nevada, Oregon, Utah and Washington on Wednesday.

More than three-quarters of the pot plants were found growing in California, about 840,000 in all.

Authorities found about 93,000 plants in Washington, with smaller amounts in the remaining states.
