International
In 1992, Canada joined most of the governments of the world in signing the Convention on Biological Diversity. The convention states in Article 8, Item (h) - In-situ Conservation - “Each Contracting Party shall, as far as possible and as appropriate: Prevent the introduction of, control or eradicate those alien species which threaten ecosystems, habitats or species.”
The program to eradicate bullfrog populations from southern Vancouver Island is, therefore, in keeping with the Canada’s domestic policies and international obligations with respect to the Convention on Biological Diversity (1992).
