Biodiversity conservation has become a defining objective of responsible and sustainable forest management. The current approach for conserving biodiversity suggests that forest practices should emulate natural disturbance patterns, and by doing so, will ensure that the habitats necessary to maintain biodiversity are available. The dominant natural disturbance type to impact the ecosystems of the southern interior of B.C. is wildfire. Although conventional forest practices (e.g., clearcut harvesting) do emulate certain aspects of wildfire disturbance (e.g., the removal of large patches of mature trees), fundamental differences exist. In particular, stands initiated by wildfire often include remnant structures from the original forest. For example, throughout B.C.?s interior, it is not difficult to find stands that were created by wildfire. These fire-generated stands are easily identified by the large fire-scarred Douglas-fir vets that tower over regenerating stands of dense lodgepole pine. The unique structures provided by these large remnants from the original forest provide important habitats for many species of plants and wildlife. As a result, emulating wildfire disturbance requires that forest practices retain portions of the pre-harvest forest, particularly Douglas-fir, within second-growth stands. This practice is referred to as green-tree retention (GTR).
