Designing skid trail systems to reduce soil impacts from tractive logging machines

Creator:: Froehlich, Henry A., Aulerich, D. E., and Curtis, R.
Abstract:: Logging on skid trails restricted to 10 percent or less of the harvested stand can reduce the area of compacted soil by at least two-thirds, In a comparative study, productivity of Douglas-fir logs per hour was just as great In an area with designated trails as In an adjacent area...

Soil compaction from low ground-pressure, torsion-suspension logging vehicles on three forest soils

Creator:: Froehlich, Henry A. and Oregon State University. Forest Research Laboratory
Abstract:: Monitoring soil density on three sites during repeated trips with a high-speed skidder showed that: During the first 20 trips, soil density primarily increased between depths of 2 to 4 inches; Density increased most during the first few trips; Density continued to increase slowly in amount and depth with the...

Trophic cascades linking wolves (Canis lupus), coyotes (Canis latrans), and small mammals

Creator:: Miller, Brian J., Harlow, Henry J., Harlow, Tyler S., Biggins, Dean, and Ripple, William J.
Abstract:: When large carnivores are extirpated from ecosystems that evolved with apex predators, these systems can change at the herbivore and plant trophic levels. Such changes across trophic levels are called cascading effects and they are very important to conservation. Studies on the effects of reintroduced wolves in Yellowstone National Park...

Equations for estimating biomass and leaf area of plants in the Pacific Northwest

Creator:: Oregon State University. Forest Research Laboratory, Gholz, Henry L., Grier, C. C., Campbell, A. G., and Brown, A. T.
Abstract:: Reliable estimates of plant biomass and leaf surface area are essential for studying primary production, nutrient cycling, hydrology, wildlife management, and fire. This paper presents equations that can be used to make such estimates for most plant species-trees, shrubs, and herbs-dominant in western and central Oregon.' We also document the...
