Abstract: Tree Farm Licence (TFL) 49, also referred to as the 'Okanagan TFL', is held by Tolko Industries Ltd. (Tolko), based in Vernon, BC. The TFL has three distinctive blocks (called A, B, and C) with a total area of about 144 800 hectares. TFL 49 is located west of Okanagan Lake near the communities of Kelowna, Vernon and Armstrong. The TFL is administered by the BC Forest Service (BCFS) Okanagan Shuswap Forest District office within the Southern Interior Forest Region. TFL49 is dominated by lodgepole pine (45%) which has been the target of Mountain Pine Beetle (MPB) since 2003. Timber harvest of dying mature pine stands has been actively pursued by the Licensees (Tolko, BCTS) since 2004 while mitigative action to rehabilitate both dead and dying young immature pine stands has been implemented since 2007. Young pine stands (< 30 years) have been the target of the Forest for Tomorrow (FFT) program funded by the Ministry of Forests. With the population of lodgepole pine accounting for over 42% of the vegetative cover on TFL49, 42% of the TFL49 land base acts as a host to the Mountain Pine Beetle (MPB). Catastrophic levels of MPB have severely impacted the vegetative cover of TFL49 since 2003 across both the immature to mature stands with ages 10 to 140 years. The Allowable Annual Cut ( AAC) was increased in December 2005 from 380,000 m3 to 500,000 m3 per year, to facilitate timely salvage of MPB affected lodgepole pine. Such harvest levels are only sustainable in the short term. The results of the thematic mapping products identifying opportunities to guide Forest for Tomorrow ( FFT) investments into the future have been ground truthed in 2010. The field verifications have found that the mapping products are reasonably accurate in identifying species, density, volumes and attack levels in the younger stands. The thematic mapping has also identified MPB activity in the mature stands and salvage operations have focused activities within the area deemed within the Timber Harvesting Land Base (THLB). There is evidence of grey attacked Pine stands in the NTHLB. Overall observation, using both the thematic mapping and field verification, suggest that the bulk of the broadcast catastrophic level mountain pine beetle attacked forest stands have run their course within TFL49. While there appears to be limited broadcast level attack in the younger managed sands, there exists a good value return on investment (ROI) opportunity to invest FFT funds into the managed stands on a proactive basis to maintain /dispose of smaller 10-15 hectare stands of the younger stands attacked by MPB. The intent, of which, is to protect the mid-term harvest supply.
