Abstract:: During August 1972, 15 vegetation plots monitered for foliar fluoride concentrations in 1971 were resampled near the Anaconda aluminum plant at Columbia Falls, Montana. Statistical analysis of the data showed that essentially the same amount of fluoride was taken in by conifers, shrubs, and grasses in 1972 as in 1971....

Abstract:: Mountain pine beetle populations reached epidemic levels on approximately 4,600 acres in Glacier National Park in 1972. Infested trees increased from 4.9 in 1972 to 10.9/acre in 1975. Majority of trees killed since 1972 were 12 inches d.b.h. and larger in size. Sufficient large diameter lodgepole pine exists to maintain...

Abstract:: Mountain pine beetle populations began increasing in Glacier National Park in 1970. Numbers of infested trees increased steadily from an average of 12 to 115 per hectare from 1972 to 1976. Total hectares of infestation have increased from 445 in 1972 to 40,419 ha in 1976. Predictive equations estimate a...

Abstract:: Mountain pine beetle populations developed to epidemic level in Glacier National Park in 1972. Buildup ratio of old to newly attacked trees was 1:1.8 from 1976 to 1977. More than 12 million trees are infested on 142,871 acres. Buildup ratio is expected to exceed 1:3 from 1977 to 1978. Management...

Abstract:: Mountain pine beetle infestation was detected in stands on the east side of Glacier National Park and the adjacent Blackfeet Indian Reservation in 1979. Infestation in the Park now encompasses an estimated 215,882 acres. About 200 acres are infested on the reservation. In areas sampled, number of trees killed per...

Abstract:: Numerous studies have demonstrated that vegetation canopies affect snow accumulation and ablation processes. In addition, estimates of remotely sensed snow covered area can be biased by the presence of an overlying vegetation canopy. Consequently, any attempts to measure, model, or map the distribution of snow in a region with heterogeneous...
