Data Sources and Methods for the Sustainability of Timber Harvest Indicator

Data

3.1 Data source

Data for this indicator come from the National Forestry Database (NFD) which is maintained by the Canadian Forest Service of Natural Resources Canada. The data contained in the NFD are provided by provincial or territorial resource management organizationsFootnote [1] and federal government departments.

The total area of Canada is from Natural Resources Canada’s Atlas of Canada.Footnote [2]

3.2 Spatial coverage

The indicator has national coverage because it includes data provided by all provinces and territories, except from Nunavut.

3.3 Temporal coverage

The indicator presents data from 1990 to 2010. Estimates of wood supply prior to 1990 did not usually take into account data for private lands and federal lands.Footnote [3]

3.4 Data completeness

Data are updated in the National Forestry Database on a bi-annual basis.

British Columbia and the Northwest Territories did not provide figures for 2010; therefore, estimates were used in order to calculate the Canadian total.

3.5 Data timeliness

The National Forestry Database is updated bi-annually with a 14-months time lag. For instance, 2010 data were collected in 2011 and published in February 2012. If there are updates or corrections to the data, they are republished in June after the first release. This indicator is current to the end of 2010.
