The study area is located in TFL 44 within Weyerhaeuser's West Island Timberlands operation, near Port Alberni. Healthy, second-growth stands containing trees from 50-100 years of age can still take many decades before developing the primary wildlife tree attribute of heart rot. However, this natural process can be significantly accelerated through fungal inoculation. In these situations, artificial creation methods may be warranted in order to recruit wildlife trees more quickly than would otherwise occur through natural cycles. An operational trial to create wildlife trees in second-growth Douglas-fir stands using fungal inoculation was initiated in TFL 44 during 2002. This report provides a summary of preliminary results from 2003, including the lab analyses of five destructively sampled treatment trees, as well as the general condition of the remaining treatment trees. Based on the preliminary destructive sampling and lab work conducted in 2003, it appears that fungal inoculation using the climbing/drilling method will successfully introduce heartrot decay into the treated Douglas-fir trees.
