California Timber Regulation and Environmental Evaluation System (CalTREES) Information Portal

Timber harvest permitting in California has begun moving into a new era with the launch of CalTREES to internal State employees. On October 1, CAL FIRE and Review Team agencies (i.e., the State and Regional Water Boards, Department of Fish and Wildlife, and California Geological Survey) began to use the new online system for reviewing timber harvesting documents. To facilitate faster and easier collaborative reviews, CAL FIRE has already entered timber harvesting documents into CalTREES and will continue to enter any paper forms submitted for review.  

Registered Professional Foresters, Licensed Timber Operators, and Landowners will soon have the option to electronically submit, track, and update timber harvesting documents on-line via CalTREES. The public now also has access to search for timber harvesting data and information and will soon be able to submit comments electronically throughout the Fall and Winter of 2018/2019, and will offer trainings to the public, Registered Professional Foresters, Licensed Timber Operators, and Landowners as new functionality become available.
