Fish and wildlife resources are held in trust for the people of the
State by and through the California Department of Fish and Wildlife
(CDFW). CDFW is concerned with activities associated with cannabis
cultivation and the effects on fish and wildlife resources. Cannabis
cultivation activities that can have adverse impacts include, but are
not limited to, diversion of water, land clearing such as timber
conversion, road construction and stream crossings, riparian vegetation
removal, and introduction of pollutants (fertilizers, amendments and
pesticides) into waterways and other habitats.
To ensure that such activities do not adversely impact fish and
wildlife resources, CDFW is engaged in environmental review and
permitting, enforcement, and coordination with other agencies developing
and implementing regulatory programs for cannabis cultivation.
