THE TREES OF BRITISH COLUMBIA: NATIVE AND NATURALIZED

Big-leaf Maple (Acer macrophyllum) , photo by Kevin Newell

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) now reported from the province. The list below aims to provide a quick overview of the tree species of British Columbia, both native and naturalized. The list is presently under review, and more will be added shortly.

While identification of our tree species might seem simple at first, there are groups that can be difficult to identify. This is a result of morphological similarity (e.g. willows) and hybridization (e.g. birches). This can make identification challenging, even for expert botanists.
