The Forest Resources Inventory (FRI) provides information about tree species, including: * composition * height * age * density Ontario’s forest resource inventories allow us to support resource management and land use decisions, and help sustain healthy, natural environments. Forest resource inventories for each forest management unit are legally required under the [Crown Forest Sustainability Act (1994)](https://www.ontario.ca/laws/statute/94c25). Every 10 years, the ministry creates a new forest management plan where inventory data is updated and must be compliant with the requirements detailed in the Act. Ontario’s FRI is also used to meet provincial, federal, and international reporting requirements. These draft FRI Packaged Product data sets are being provided for the purpose of consultation and product development. The number of attributes and the algorithms used to generate the attribute as well as the data formats will change over time and should not be considered the final version. A final version of the structure and content of the FRI will be made available after the required consultations are complete. Data sets will be made available for each Forest Management Unit as they are produced.
