| dc.description |
Dwarf mistletoes exert an impact on forest productivity, but this impact
can be reduced through management practices. Even infested stands can
yield considerable volumes if proper control methods are used. Projections
of future yield increases due to control efforts are made. Cost
of treatment in fiscal year 1973 was $51 per acre in Douglas-fir and
western larch and $19 per acre in lodgepole pine. The benefit:cost
ratio of control is 3.25:1 in Douglas-fir and western larch and 2.42:1 in
lodgepole pine. These benefit:cost ratios are based on primary resource
values alone, and do not include value added to the economy in wages and
social benefits. Control was accomplished on nearly 9,000 acres in
fiscal year 1973; Insect and Disease Control funds accounted for about
one-half the expenditures. The control program should be continued. Steps
for the land manager to take for program continuation are recommended. |
