The preparation of suitable sites for planting and growing of tree seedlings following logging is recognized by British Columbia Forest Service as a major silvicultural problem in the Central and Northern Interior regions of the province. Over the past few decades, scarification trials have been made with various types of...
The number of sawmills in the coastal lumber-producing area
of British Columbia diminished from 364 In 1955 to 162 in 1968. In
the interior of the province the reduction in plant numbers was from
2125 to 740. Over the same period lumber production in the province
increased from 4.9 billion...
Site preparation treatments are often used prior to the planting of clearcut
forest lands to improve planter access and to increase the number and quality of
planting spots. Most mechanical site preparation treatments alter the
configuration and material composition of surface soil materials, and can have
marked effects on soil...
A field study was established to explore stand structure and development patterns of
mature, mixed-species forests in the Interior Cedar-Hemlock (ICH) zone: moist cold
subzone of northwestern British Columbia. The species of interest in the study area
were: western hemlock (Tsuga heterophylla (Raf.) Sarg.), western redcedar (Thuja
plicata Donn), lodgepole...
Despite the importance of tropical forest ecosystems in the global carbon cycle, there have been few studies of carbon dynamics in this biome. The magnitude of carbon stocks in the tropics and their changes over time are poorly known since ground-based observations are lacking. In this study, total carbon stocks...
