The Nature Conservancy of Canada says it is expanding a wilderness corridor north of Montreal that's essential for the movement of wildlife.

The nature group announced in a news release that it has protected 95 hectares of a natural passage that links four major forest areas in Sainte-Agathe-des-Monts in the Laurentians area.

The organization says such corridors are essential, given that many natural areas are becoming fragmented by man-made infrastructure such as roads, highways and cities.

The protected area includes typical Laurentian vegetation such as sugar maple groves and birch fir stands, as well as wetlands that provide a habitat to several species of birds and amphibians.

The woods are home to black bears and reptiles such as the smooth green snake, which is a species likely to be designated threatened or vulnerable under the Quebec government's threatened or vulnerable species act.

The land was acquired through a mixture of purchases and donations.
