Precise estimates of biomass are needed in productivity and nutrient cycling studies, and for improved estimates of potential productivity. Improvements in prediction of foliage and branch biomass were sought by comparing multiple regression models u

Although mixed-severity fires are among the most widespread disturbances influencing western North American forests, they remain the least understood. A major question is the degree to which mixed-severity fire regimes are simply an ecological interm

Summary I We examined how rapidly soils can change during secondary succession by observing soil development on 350-year chronosequences in three pristine forest ecosystems in south-east Alaska. 2 Soil surfaces, created by different windthrow events

By assessing productivity and ecosystem nutrient distribution, this work extends the early classic studies of the influence of N 2 fixers and conifers on soil development and nitrogen accumulation in a primary succession chronosequence at Glacier Bay

We evaluated the effects of stand density on nitrogen (N2) fixation, net primary production (NPP) photosynthate partitioning, and canopy characteristics in 5—yr—old red alder (Alnus rubra Bong.) plantations. Our study used acetylene reduction and

Cloud water and rainwater were examined at remote sites in southeastern Alaska and coastal Oregon using standardized collection and analytical techniques. Cloud water and rainwater were characterized by extremely low concentrations of most ions excep

Estimates of wood yield and nitrogen accretion for pulpwood and sawlog rotations of red alder on good sites were coupled with information on managed yields of Douglas-fir to compare six management systems: unfertilized Douglas-fir, fertilized Douglas
