The Canadian Forest Service has worked with the provinces and territories to develop a new approach for the National Forest Inventory (NFI). This new approach is a response to changes in data and information needs. For example, data to evaluate criteria and indicators of sustainable development are required, as well as data on changes in the resources and data on non-timber resources.
The basic NFI sampling design includes the selection of sample units using a 20 × 20 km grid network; photo plot attribute estimation from air photos; and the selection of a subset (1 in 10) of these photo plots for ground sampling. These guidelines describe the configuration and major components of the ground plot design.
