|1 Source: 1995/96 Ministry of Forests Resources Inventory Branch reports. Includes only productive forest land where timber harvesting is restricted partly or wholly by factors such as timber quality, accessibility and environmental sensitivity. Excludes:
2 A timber supply area (TSA) is an area of the province designated by the Ministry of Forests for the purpose of analysis, planning and management of timber resources. Boundaries have been determined on the basis of present and expected population centres, transportation networks, manufacturing facilities, and existing administrative boundaries. TSA report data are derived from the latest assembled TSA files released by the Resources Inventory Branch.
3 A tree farm licence (TFL) is a privately managed, sustained-yield unit in which the Crown adds forest land to the company's private holdings (if any) sufficient to provide a continuous supply of wood for an existing or planned mill. The private and Crown lands comprising the licence are described as Schedule A lands or Schedule B lands. Schedule A lands are Crown-granted lands (privately owned lands), or Crown lands with timber alienated (such as licences, leases and timber berths) that are now included in the licence area. Schedule B lands are Crown lands on which the timber is fully committed by the province to the licensee. TFL report data are derived from the management plans of the licensees, except for the following:
4 Stands with lodgepole pine and whitebark pine or deciduous species as the leading species are immature if the stand age is 80 years or less; when the stand age is greater than 80 years, the stand is mature. Otherwise, all stands having conifers other than lodgepole pine and whitebark pine as the leading species are immature when the stand age is 120 years or less; when the stand age is greater than 120 years, the stand is mature.
5 Not Stocked Productive Forest Land. Includes areas (Current and Pre-1982 Backlog) that were disturbed by harvesting, wildfire or other causes, and were not satisfactorily restocked. Anticipated regeneration delay may be between one and seven years on current lands that are not satisfactorily restocked. Also includes non-commercial areas, either covered with commercial tree species, or at least 60 per cent covered with brush that is higher than one metre.
