CalTREES is the online timber harvest permitting system that will streamline the submission and review processes for timber harvesting documents. The system is used by CAL FIRE staff and Review Team agencies (State and Regional Water Boards, Department of Fish and Wildlife, and California Geological Survey) to process and review timber harvesting documents submitted on paper or online. 

Features of CalTREES

The CalTREES system has several features that are available to the public:

  • Ability to search for timber harvesting documents and related information
  • Run reports online and get the most up to date information

If you register for an account in CalTREES, there are more features available, such as:

  • Submission of Notification Requests to receive email notification about timber harvesting documents
  • Ability to submit Public Comments online
  • Registered Professional Foresters, Licensed Timber Operators, and Landowners have the capability to electronically submit, track, and update Emergency and Exemption timber harvesting documents

Online Submission of Emergency and Exemption Notices

Online submission of Emergency and Exemption harvesting documents is available in CalTREES.  The system is designed to guide you through the online submission process.  CalTREES will indicate required fields on each form and provide you with reminders about regulatory requirements.  Navigate to the user guide and training video in the Training Materials section of this page to view all of the CalTREES features.
