Data and tools
Standard statistical reports provide estimates of basic forest attributes such as area, volume, and biomass, summarized in various ways (e.g., by forest type, age class, ownership, protection status, etc.) for geographic units: Canada, Terrestrial Ecozones and Boreal Zone. Reports are available here in various formats such as HTML, PDF and CSV.
You can create your own report by interactively querying the National Forest Inventory database for geographic units: Canada, Terrestrial Ecozones and Boreal Zone. When logged in, NFI collaborators (and other authorized users) can create their interactive reports for NFI Units and Jurisdictions as well.
NFI data have been used to produce a suite of continuous maps of forest properties. The "k Nearest Neighbours" (kNN) method was used with 26 spatial data layers, including MODIS spectral data and climatic and topographic variables, to produce continuous maps of 127 forest attributes at a 250 m resolution.

The biomass calculator
The biomass calculator User Guide. provides a decision key to help you select the right tool for your biomass estimation task and provides guidance on how to use the various tools.
The biomass of four components (stem wood, stem bark, branches and foliage) for an individual tree can be calculated using the Individual Tree Biomass Calculator.
The biomass of four components (stem wood, stem bark, branches and foliage) for a forest stand can be calculated using the Merchantable Forest Stand Biomass Calculator or the Non-Merchantable Forest Stand Biomass Calculator.
The stand biomass calculators use a suite of biomass models to estimate biomass. The biomass models and their parameters were updated from the originals, which are described in the original report, Model-based volume-to-biomass conversion for forested and vegetated land in Canada which was published by the Canadian Forest Service in 2007.
Requests for custom estimates, map products, and raw data can be made by submitting a NFI Data Request Form. If you would like to talk to someone about your data needs before completing the form, please contact the National Forest Inventory Project Office at [firstname.lastname@example.org]. All requests are subject to approval by the NFI.
The information submitted via a NFI Data Request Form is used to track NFI data use and impact and is stored securely for internal use only. Data requestors will be contacted by the project office to follow up on submitted data requests.
kNN map datasets are available for download here.
The following tools are for NFI collaborators (and other authorized users) only.
