The information found on the Tree Identification page is from the government of British Columbia publication called the Tree Book: Learning to Recognize Trees of British Columbia. This book states that there are about 40 trees native to the province.
However, the Electronic Atlas of The Flora of British Columbia states: "there are more than fifty species of native trees, and several subspecies and varieties, found in British Columbia. In addition, there are several naturalized species (cultivated species that are spreading in the wild)."
Of the 50+ species of native trees that grow in BC, 40 are listed in the Tree Book. Of those 40, about half grow on Vancouver Island.
The biggest tree species is Western red cedar, followed by Douglas fir, and Sitka spruce. Sizeable Grand fir, Bigleaf maple, and Garry oak can be found on the island.
The Tree Book is an excellent free resource that contains interesting, basic tree information:
"For each tree, you will find key identifying features such as bark, fruit or cones, and needles or leaves, along with photographs and descriptions. Be sure to check the distribution map to find out if the tree grows in your area.
The Biogeoclimatic map of British Columbia provides more information and maps for specific zones.
There is also information on the kind of environment in which each tree species likes to grow, the other trees and plants that usually grow with it, and some of the animals that consider it part of their habitat.
We have provided some information about present and past uses for each tree. At the end of the book, you will find some naturalists' notes to help you answer questions such as, What is an Ecosystem? Why do trees grow where they do? and Do ecosystems always stay the same?"
The Tree Book is available online and for download on the website found here.
I have included a few of the main tree species from the Tree Book that grow in the forests of Vancouver Island. Trees species are listed alphabetically by common names.
