Dwarf mistletoe loss assessment in east side Northern Region national forests

Creator:

Dooling, Oscar J. and United States. Forest Service. Northern Region. State & Private Forestry

Abstract:

We conducted a combination road/plot impact survey for dwarf mistletoe in lodgepole pine on six East Side National Forests in 1978. The road survey showed infestation percentages ranging from 28.2 on the Custer to 52.4 on the Beaverhead. The plot survey showed annual cubic foot volume losses ranging from 106M...

Preliminary results of seedling damage surveys in young plantations on selected forests in Region 1

Creator:

Hard, John S., Rice, John Leslie, and United States. Forest Service. Northern Region. State & Private Forestry

Abstract:

Based on per acre costs, plantation establishment is one of the most expensive silvicultural practices (Pfister 1976), but only token studies have been done on frequency and causes of seedling injury and mortality in Region 1 plantations (Wenner 1976). Therefore, we conducted a survey in 1978 on four National Forests...

Evaluation of proposed dwarf mistletoe management projects on the Deerlodge National Forest

Creator:

Dooling, Oscar J. and United States. Forest Service. Northern Region. State & Private Forestry

Abstract:

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...

Potential for defoliation by western spruce budworm in northern Idaho and Montana, 1977

Creator:

Tunnock, Scott and United States. Forest Service. Northern Region. State & Private Forestry

Abstract:

Epidemic populations of the western spruce budworm persist in the Northern Region. Aerial surveys made in August 1976 showed a decline in the acreage of aerially visible defoliation. In northern Idaho, the defoliated area dropped from 831,487 acres in 1975 to 655,711 acres in 1976, down 21 percent. Surveys in...

Status of mountain pine beetle infestations, Kootenai National Forest, Montana, 1977

Creator:

McGregor, Mark D. and United States. Forest Service. Northern Region. State & Private Forestry

Abstract:

Mountain pine beetle populations increased to epidemic levels on the Kootenai National Forest in 1972. Nearly 397,000 trees containing almost 32 million board feet have been killed. More than 84,000 trees will probably be killed in 1978. Infestation has the potential to intensify in high hazard stands, and some increase...
