Natural environments

Even though urban development is putting an evergrowing pressure on the last natural environments of the region such as wetlands, forests, streams and banks, Laval still has the potential to become a flourishing and sustainable city thanks to the richness of its biodiversity and the quality of its natural habitats.

Urban woods and forests

There are 16 main woodlands on Laval's territory. Some of them are being taken care of by organizations, but the majority remain orphaned and unknowned by the population. The metropolitan area of Montreal, including Laval, is located in the maple hickory bioclimatic domain, which is an extremely rich and diverse ecological community strongly shaped and altered by human activity.


Wetlands are sites where water influences the soil and vegetation due to its presence for a sufficient amount of time (Couillard and Grondin 1992). Wetlands can therefore be permanently or temporarily flooded, but the soil and or dominant vegetation demonstrate the work of water. In Quebec, we classify wetlands into ponds, marshes, swamps and bogs.

Protection of the Totem pathway area

CRE de Laval is proud to have collaborated with the Comité de protection de l’environnement de Saint-François (CPESF) to help promote the ecological importance of the Totem pathway area to the members of the Revision of the land use planning Committee.

Alien invasive species

Alien invasive species are plants or animals that are not native to their environment, therefore qualified as alien. They were either introduced or have migrated. The moving and colonization of new ecological niches is a natural process which is a key component of species adaptation and evolution. However, migration and species introduction is greatly enhanced nowadays and is a massive threat to biodiversity.

Protection of Trait-Carré Woodland

CRE de Laval and Les Amis du Boisé du Souvenir offer a report that consists of a very first characterization of Trait-Carré Woodland - there is also an evaluation of some impacts of urbanization, such as the decline of canopy and heat islands. The study also highlights the social benefits of green spaces in urbanized zones.

Streams and water bodies

Streams run through about 250 kilometers of Jesus Island. Since 2013, CRE de Laval characterizes the main streams in the context of the Urban streams of Laval project.

Banks and shorelines quality index assessment

Since 2019, CRE de Laval works with the City of Laval in order to assess the quality index of the banks and shorelines of Laval.

Book - ''Nos survivants : Les arbres remarquables de Laval''

CRE de Laval has published a book on the most spectacular and exceptional species of trees found in Laval, titled « Nos survivants : les arbres remarquables de Laval ». You may contact us to get your own copy of the book for $30, or better yet - become a member of CRE de Laval and get your copy for free!

Urban Streams of Laval Project

With several partners, CRE de Laval has developed a project on urban streams of the region in order to evaluate the impacts of urbanization on these sensitive areas and to implement measures that would prevent their deterioration and even improve their situation. We therefore have already surveyed 42 kilometers of banks!
