1. An assessment of dwarf mistletoes in Montana

Creator:: Dooling, Oscar J., Eder, Robert G., and United States. Forest Service. Northern Region. State & Private Forestry
Abstract:: Dwarf mistletoes reduce tree height and diameter, and thereby cause a reduction in volume production. We estimate that volume reduction in Montana is about 33.2 MM cubic feet per year. Mistletoe effects are problems in some areas because of the demands we have placed on the Forests for goods and...

2. Growth impact, spread, and intensification of dwarf mistletoe in Douglas-fir and lodgepole pine in Montana

Creator:: Dooling, Oscar J., Johnson, Ralph R., Eder, Robert G., and United States. Forest Service. Northern Region
Abstract:: A permanent study was established in 1970 and 1971 to measure the impact, spread, and intensification of dwarf mistletoe on precommercially thinned Douglas-fir and lodgepole pine in Montana. Mean diameter growth on all plots was reduced 21 percent in Douglas-fir, but the reduction is only significant at the 0.15 level....

3. Insect and disease surveys of some Inland Empire Tree Improvement Cooperative test plantings

Creator:: Dooling, Oscar J., Gibson, Kenneth E., and United States. Forest Service. Northern Region
Abstract:: Potential problem pests found were Armillaria root disease, pocket gopher, western pine shoot borer, and white pine blister rust. Early detection of problem pests allows management actions to be taken if needed to prevent serious impacts. Unit managers should check the areas periodically and call on pest management specialists to...

4. Evaluation of proposed dwarf mistletoe projects on the Lolo National Forest, Montana

Creator:: Dooling, Oscar J. and United States. Forest Service. Northern Region. Cooperative Forestry & Pest Management
Abstract:: Residual Douglas-fir, western larch, and lodgepole pine are dwarf mistletoe-infested and pose a threat to existing regeneration. Felling or girdling these residuals, along with sanitation/thinning, will reduce mistletoe intensity and increase future volume yields. Present net worth of the project is $48.05/acre. Benefit cost ratio is 1.97/1. Use of pest...

5. Dwarf mistletoe management in the Northern Region : is it cost-effective?

Creator:: Dooling, Oscar J. and United States. Forest Service. Northern Region. Cooperative Forestry & Pest Management
Abstract:: An investment is an expenditure made with expectation of future gains, financial or otherwise. Dwarf mistletoe management, and even forest management itself, often involves investment for social and community benefits without expectations of direct financial gain. The USDA Forest Service Northern Region's dwarf mistletoe program, 1966 to 1981, is used...

6. Evaluation of a proposed dwarf mistletoe project, Stevensville Ranger District, Bitterroot National Forest, Montana

Creator:: Dooling, Oscar J., Wiegand, Robert, and United States. Forest Service. Northern Region. Cooperative Forestry & Pest Management
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....

7. Status of Douglas-fir bark beetle, Madison Ranger District, Beaverhead National Forest, 1982

Creator:: McGregor, Mark D., Oakes, Robert D., Dooling, Oscar J., and United States. Forest Service. Northern Region. Cooperative Forestry & Pest Management
Abstract:: Douglas-fir beetle has increased to epidemic levels in mature-overmature Douglas-fir that has been top killed by western spruce budworm. About 42 trees per acre have been killed in an area at Lyon's Face and 36 trees per acre in other areas along the Madison River during the past 3 years....

8. Evaluation of proposed dwarf mistletoe projects, West Fork Ranger District, Bitterroot National Forest, Montana

Creator:: Dooling, Oscar J., Underwood, Stanley K., and United States. Forest Service. Northern Region. Cooperative Forestry & Pest Management
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 projects ranges from -$1 to $39 per...

9. Evaluation of dwarf mistletoe control projects, Sula and Darby Ranger Districts, Bitterroot National Forest

Creator:: Dooling, Oscar J. and United States. Forest Service. Northern Region. State & Private Forestry
Abstract:: Residual Douglas-fir are dwarf mistletoe-infested and pose a threat to regeneration. Felling of these residuals will reduce dwarf mistletoe intensity and increase future volume yields. The benefit/cost ratio at 4 percent for the current rotation is 0.51/1 on the Sula RD and 0.45/1 on the Darby RD (both negative ratios)....
