Artificial inoculation of decay fungi into Douglas-fir with rifle or shotgun to produce wildlife trees in Western OregonWestern Journal of Applied Forestry (2004)
AbstractA total of 188 Douglas-fir trees were treated to determine whether fungal inoculation with rifle or shotgun promoted stem decay and subsequent use by cavity-nesting birds in the Coast Range in Oregon. Inoculated trees were either live or killed by topping. Topped trees were climbed and severed just below the lowest whorl of live branches. Fungal inoculum was delivered by either a 0.45-70 caliber rifle or a 12-gauge shotgun to tree trunks at a height of about 8 m aboveground. Inoculum of either Phellinus pini or Fomitopsis cajanderi was grown on small wooden dowels or sawdust and fitted into the rifle slug (dowels) or behind the shotgun slug (sawdust). Sterile dowels or sawdust were used as a control. After 5 years, all topped trees had died, and at least 50% had sap rot as indicated by the presence of conks of Trichaptum abietinum. Conks of Crytoporus volvatus, Fomitopsis pinicola, or P. pini were sometimes observed on topped (dead) trees...
