The strength of both undisturbed and compacted soils from 10 sites
in the slide-prone Tongass National Forest in SE Alaska were studied.
Index property tests were also conducted on disturbed samples. The
index tests included natural water content, Atterberg Limits, specific
gravity of solids, grain size distribution, and moisture-density relationship....
Rainfall, discharge, traffic, and suspended sediment
were monitored for a period of 4.5 months at three
locations on a secondary haul road at Polk Inlet, Alaska to
determine the important processes and variables involved in
surface road erosion for this area. Three sites all less
than 500m² and within 5...
Several understory conununities display successional stages during the first two hundred years following logging or fire disturbance in the coastal Picea-Tsua forests of southeast Alaska. Residual shrubs
and tree seedlings increase their growth exponentially after overstory removal. Understory biomass peaks at about 5000 kghayr fifteen to twenty-five years after logging....
