Large Oak
All of the tree species listed below – even those which are non-native to Ontario – can be useful in urban plantings.
Naturalization and restoration projects should only use native species that were found in the local area historically. If you are concerned that climate change may change the species composition of our forests in the future, keep in mind that climate prediction science is still very young and the recommended approach at present is to use species that are found in the local region now, and source them from seed that came from individuals from the south end of the region so they are suited to the future warmer climate, if it changes. If the climate doesn’t change as drastically as predicted by some people, your project will still be successful. See the FGCA website for more info.
An ideal urban neighbourhood would have a mixture of these species at different ages to provide diversity in case of disease or storm damage. See Where to Plant for optimal growing conditions for these species and others.
