The information that follows gives a background to the Arrowsmith TSA, an outline of the timber supply issues, an incremental silviculture history and a link to the timber supply review process. The latter part of this document outlines opportunities to increase timber supply and timber quality, provides working targets and supports these opportunities and targets with a proposed 5 year incremental silviculture program.
The Arrowsmith TSA is located on the southern half of Vancouver Island within the Vancouver Forest Region. Many of the communities within the district are heavily dependent on the forest industry. The TSA consists of the Small Business Forest Enterprise Program (SBFEP) charted areas and Forest Licences. Table 2.02 Land Area
Table 2.03 Annual Allowable Cut
The initial harvest level (IHL) of 468,500 m3 was maintained for only one decade. After this, declines averaging 12%/decade are expected until a midterm harvest level of 277,000 m3 (42% below IHL, 30% below TSR 1 AAC) is reached 50 years from now. This downturn will continue until 140 years from now, when the harvest rate will increases by 10%/decade to reach a long-term harvest level (LTHL) of 377,000m3 (30% below IHL, 14% below TSR 1 AAC).
