In some areas of British Columbia, especially where forest harvesting has been practiced for many years and second-growth stands are predominant, or where ecosystem restoration may be required (e.g., riparian rehabilitation), there is often a shortage of suitable wildlife tree habitat. 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. In Oregon, fungal inoculation trials have achieved trees with heart rot suitable for cavity excavation in 4-6 years, much earlier than natural fungal colonization and decay rates (C. Parks, USDA For. Service, pers. comm. 2000; Parks 1996). Consequently, an operational trial to create wildlife trees in second-growth Douglas-fir stands using fungal inoculation was initiated in TFL 37 and TFL 44 (north-central and western Vancouver Island, BC) in 2002.
