Definition and examples
A number of tree and shrub species are listed under the Endangered Species Act in Ontario. This act seeks “to protect species that are at risk and their habitats, and to promote the recovery of species at risk” (Endangered Species Act, 2007). If you do wish to plant one of these trees, you must make sure that they are planted in an ethical manner and in an area that promotes the tree’s survival. Furthermore, you cannot plant endangered trees that originate from non-wild sources.
