There are some areas of productive forest in Canada not yet covered by forest inventory programs. These gaps occur in transition forest of generally low current commercial value.
Sampling was carried out in the Alberta and Saskatchewan gaps to provide broad but statistically objective estimates of area and volume for Canada’s forest inventory.
A network of photo plots was established in each gap. Plots were described by photo interpretation according to 1986 national inventory codes. Volume estimates were interpreted for the stocked productive forest plots. The sample was calibrated with a regression estimator using a subsample of ground plots.
The 5 250 000 hectares of uninventoried productive forest land contains 409 140 810 cubic metres of wood, of which 39% is in Alberta, 10% is in southern Saskatchewan, and 51% in northern Saskatchewan.
