They recognize that they cannot protect any species without simultaneously protecting the diversity of wildlife and habitats on which it relies.

3. Secure and thriving: They are working for the day when vulnerable North American species rebound to the point that they are secure — no longer threatened with rapid decline or extinction — and thriving in robust, well-distributed populations.
4. Network of healthy lands and waters: Wildlife has the greatest chance of being secure and thriving if it is supported by a transnational network of public and private lands, rivers and coastal waters, core natural areas and working landscapes.
