Trees are essential infrastructure in our towns and cities, say urban foresters

People need trees — particularly in our cities. Urban forests clean the air, lower stress levels, reduce energy costs and mitigate flooding. Gillian talks to three international tree experts about nurturing nature in the concrete jungle.

There are more trees in Canada than in any other country on the planet, except for Russia.

Most of​ our forests are in the wilderness, but we also enjoy — and depend on — the green canopies of our cities and towns. Urban forests clean our air, lower our stress levels, reduce our energy costs and mitigate the risk of floods. Little wonder that urban foresters are ​now ​promoting trees as​ a critical part of a city's infrastructure, as essential as roads and sewers.​ ​

G​uest host Gillian Findlay ventured to the Mississauga campus of the University of Toronto to speak with three tree experts​, as they sat in the shadow of a nearby forest​. They were ​speakers at a conference called The Urban Forest of Tomorrow, organized by Urban Forest Innovations.
