Invasive Species

Invasive alien plant and animal species are invading the Township of Lanlgey and threatening to destroy native plant and animal communities.

By getting involved and educating others about the threat of invasive species we can have a huge impact and possibly control the spread of these pesky aliens. Visit Invasive Plants of Southwestern BC for information about invasive plants that are theatening natural habitats in Southwestern BC.

The Invasive Species Council of Metro Vancouver along with Metro Vancouver have put together best management practices for managing invasive plant and animal species in our region.  Visit management practices for their guides
