ENVR 1000 Lecture Notes - Lecture 4: Tembec, Bioaccumulation, Local Extinction
Features of forests and forests in canada- coastal rainforest, boreal forest, and temperate deciduous forests. Harvesting approaches and strategies- clear cutting and selective cutting. Strategies in sustainable forestry management- iso vs. fsc. Tembec case study- an example of ecosystem management and fsc research. A plant community dominated by trees and other woodsy plants as well as shrubs and grasses. Generally distinguished by species, density, and soil types. Divided into vertical layers: canopy, shrub, forest floor. Forest regions (boreal, coastal rainforest, temperate deciduous forests) Soil is formed by organisms decaying and dying, rich soils are in the forests with a wide biodiversity. Logging: northward expansion, harvesting previously uneconomical trees. Changing the patterns of precipitation and temperature, changing and encouraging pests (pine beetles) Found in the coastal rainforest regions (great bear rainforest) Numerous ecological niches and often very diverse systems. Multiple vertical layers representing different tree species in some cases. These forests are vey rare, as they are undisturbed.
