Note: This indicator will be addressed fully, with detailed
information and an assessment, in a future edition of the report.
Why is this important?
Timber production forests provide the resource base for B.C.’s forest
- Timber production forests – forests from which timber has been, or is
expected to be, harvested – exclude protected forests, other reserves and
forests that are uneconomical for timber production.
- Their extent has changed historically, and further changes are likely.
Currently, they cover about 25 million hectares (less than half of British
Columbia’s forests). About half are a mix of older and younger forests
originating from natural disturbances, and have never been harvested. The
remaining half are younger forests that have regrown after timber harvests,
and some of these are now being harvested a second time.
- The time required to grow harvestable trees in B.C. is typically between
40 and 120 years, depending on the productivity of the land, as influenced
by climate, soil, tree species and disturbances.
- Less than 1% of the timber production forests are harvested annually.
- To maintain non-timber values within timber production forests (e.g.,
visual, cultural, wildlife, riparian and old-growth ecosystem values),
timber harvests are deferred or limited in various ways.
- Timber production forests are subject to competing demands for land use,
natural disturbances and climate change (see Protected
forests, Recreation, Range,
Ecosystem dynamics, Greenhouse gases).
- The state of the timber production forests may affect wildlife habitats,
water quality (see Ecosystem diversity,
Water) and economic outputs (see
Timber harvest, Jobs and communities,
- Management responses include land use planning and operational planning
(see Public involvement, First Nations
involvement, Law), prompt reforestation,
controlling wildfires and pests, and regulating the rate of logging (see
Silviculture, Ecosystem dynamics,
