Notice: CDFW is going paperless! All notifications for cannabis related projects can be submitted online through the EPIMS Permitting Portal. California is unique and diverse with the highest level of biodiversity in the entire nation. CDFW has a public trust responsibility to protect and conserve California’s fish and wildlife resources. Cannabis cultivators, like other project proponents, must comply with Fish and Game Code and other regulations. Working together, we can ensure environmentally-friendly cannabis cultivation.
