The City of Rosemère's Urban Canopy Explorer lets you visualize the characteristics of the city's urban forest and public trees, such as the species, functional group or ecosystem services they provide. It also provides the functional diversity index and the canopy index. The first index corresponds to the effective number of functional groups. Tree species are classified into 9 functional groups based on similar biological characteristics. An index below 5 is considered low or very low, while an index above 7 means that the functional diversity of the area is high or very high. The higher the diversity, the more the forest will be able to cope with a wider range of disturbances, since each functional group reacts differently to a given type of stress. Finally, the canopy index indicates the amount of ground shade provided by trees. In the event of a heatwave, trees will provide important pockets of coolness for the population.

You can refine your search by using the menu on the right. For example, if you want to look at the distribution of a particular species, you can select "linden" in the "genus" section of the right-hand menu.
