Coniferous trees are the climax species in forest succession. Eventually they shade out alder and other plant species. Western red cedar, western hemlock, Douglas fir and lodgepole pine are found on the mountain. Adaptations to reduce water loss include sunken stomata and thick cuticles. In several locations on Burnaby Mountain, conifers can be seen growing on decaying nurse logs and stumps.
Dead trees become snags, which provide habitats for birds and rodents.
Western red cedar is fairly common while Douglas fir is found here and there. Western Hemlocks are common. Hemlocks can frequently be observed along with two species that are detrimental to their health. Dwarf mistletoe is a parasite that causes the erratic growth of branches. Various plant species are usually sighted at the forest's edge.
