For threatened and endangered species, a range shift or a move into areas they previously didn’t occupy can bring great challenges. Climate change, invasive species, and ever-encroaching human development can all cause a shift in habitability of certain areas; places a species used to call home may no longer be suitable, and areas that at one time couldn’t hold a species may now be ideal. When threats to species change or intensify, it can be hard for the policies meant to protect species to keep up. How do our environmental policies protect species when their habitats shift or expand? What happens when an area previously unoccupied by a species is now essential to their survival?
