Data Sources and Methods for the Sustainability of Timber Harvest Indicator

Data

3.1 Data source

Wood supply and harvest estimates are drawn from the National Forestry Database (NFD), maintained by the Canadian Forest Service of Natural Resources Canada. The data contained in the NFD are provided by provincial and territorial resource management organizationsFootnote [1] and federal government departments.

Canada’s total area is estimated using the Atlas of Canada 1,000,000 National Frameworks Data, Administrative Boundaries. World forest area is drawn from the State of the World’s Forests 2012.

3.2 Spatial coverage

The indicator includes all provinces and territories, with the exception of Nunavut, which is not a National Forestry Database partner.

3.3 Temporal coverage

Annual estimates from 1990 to 2011 are included.

3.4 Data completeness

Data are updated in the National Forestry Database on a biannual basis, and include all estimates as provided by reporting jurisdictions.

3.5 Data timeliness

The National Forestry Database is updated biannually, with a 14-month time lag for the first update each year. For example, data for 2011 were collected in 2012 and preliminary totals were published in February 2013. Updates and corrections to the data are captured, and final data were published in June 2013. This indicator is current to the end of 2011.
