Mark record


The national forest inventory in Canada is a spatially referenced roll-up of provincial, territorial, and federal source inventories. The majority of source inventories are management type inventories based on aerial photo-interpretation and renewed on a 10-20 year cycle. All source inventories are converted to a set of national classifiers and aggregated to 'cells'. A cell is usually equivalent to a 10 x 10 km map sheet. The information in the national inventory is on the average 10-15 years old with older blocks in remote areas. Levels of details and local inventory procedures vary across the nation. Given the increased demand for up-to-date forest resource information the shortcomings of the national inventory is recognized and a pilot project is underway to demonstrate a new generation of 'holistic' inventories.
