| dc.description |
Residual lodgepole pine in older clearcuts are dwarf mistletoe-infected
and pose a threat to regeneration present. Removal of
these residuals coupled with planned or completed precommercial
thinnings will effectively reduce dwarf mistletoe to an insignificant
level and increase future volume yields. The benefit/
cost ratios based on timber values alone are negative for both
areas at both 10 and 6 percent discount rates, but other benefits
outweigh the economic ones. Dwarf mistletoe management is
recommended. |
