Abstract:: Residual Douglas-fir and lodgepole pine are dwarf mistletoe-infested and pose a threat to existing regeneration. Felling or girdling these residuals, along with sanitation/thinning of dense patches of regeneration, will reduce dwarf mistletoe intensity and increase future volume yields. Present net worth of the project is $0.50/acre. Benefit/cost ratio is 1.01/1....

Abstract:: Residual Douglas-fir left after harvesting are dwarf mistletoe-infected and pose a threat to regeneration. Felling of residuals, coupled with planned slash disposal and thinning, will effectively reduce dwarf mistletoe intensity and increase future volume yields. The benefit/cost ratio based on timber values only, for the current rotation, is 0.041/1 at...

Abstract:: The cranberry girdler, Chrysoteuchia toparia Zeller, has caused increasing damage to tree seedlings in the Coeur d'Alene Nursery since 1980. Heaviest feeding has occurred on the tap roots of 2+0 Douglas-fir stock. By 1983, 8.2 percent of the seedlings examined in seedbeds were injured by this moth. A spray program...
