This guide provides information to help identify all the trees that you are likely to encounter in green spaces in the greater Montréal area. These trees are mostly native species. A few are species which have established populations but are not native to this region.
The illustrations are taken from a guide to the native trees of New England and Canada published in 1901, which you could consult online as well. This book is in the public domain, and is available through the Biodiversity Library—Deme, L.L., H. Brookes and E. Bigalow Gleason. 1901.
