Document Summary
Slide 3: management practices in canada: provinces responsible for: 77, federal and territories: 16% Slide 7: will try to hide the patches of the forest: animals will hide in these patches away from predators decrease in stand diversity. Slide 8: reforestation: until 1985: considered to be unnecessary, now: still mismatch between trees removed and reforestation, 2009: less than 450 000 ha planted, 2009: approx. Geog 2ei3: as a result, not enough managed forests. Increased pests: mountain pine beetles lays eggs underneath the bark of trees and the eggs will feed themselves off the free and then a pine beetle emerges, creation of fungal infection that harms the tree. Slide 13: spread across the province, 2013: 80% of mature pine trees consumed b/c of the mountain beetles infection. Forests and endangered species: of species considered at risk in canada: 65% are forest-related, ants, beetles, etc, 85% of species in some forest, over 1000 species of invertebrates in a single strand.
