Tree Farm Licence 44 (TFL 44) is an area based tenure held by Western Forest Products. (WFP) The TFL is located in and around Barkley Sound, Alberni Inlet and Great Central Lake.
Approximately every 5 years the Chief Forester of BC determines a new annual allowable cut (AAC) for the TFL, after considering information provided by the company through the Management Plan process (MP). The MP information includes a timber supply analysis that will be reviewed by the Chief Forester as part of the AAC determination. Since the last AAC determination in 2003, the area of the TFL available to WFP has been reduced through the removal of private lands from the licence, and by the surrender of operational areas through the Forest Revitalization Act of 2003. The WFP AAC in TFL 44 is currently 946,744m3. Further decreases in the AAC are anticipated as areas identified as Treaty Settlement Lands are removed from the TFL.
A key step in determining the AAC is the establishment of what constitutes the timber
harvesting land base (THLB). The THLB is established by excluding areas from the TFL land base that will not be harvested for one reason or another. This process is often referred to as ?netting down the land base?. At the same time as net downs are considered, the THLB is split into areas that could be harvested by conventional, or on conventional logging methods. Values can be assigned to the forest using the forest cover data so that the harvestable areas can also be defined as economic or un-economic to harvest based on the estimated harvest costs.
Conventional harvest areas are those forest areas where roads could be built using he current standard industry practices, so that ground based or cable yarding systems may be utilized. Non-conventional areas are those areas that could only be harvested using long line systems, helicopter, or balloon logging systems. Previous AAC determinations have at times partitioned the AAC based on the contribution of the non-conventional and marginally economic timber stands.
