Climate change (AGW) indicator species - video link edit

This article only mentions a native zone up to coastal Georgia. In this video (https://www.youtube.com/watch?v=DkjV07IMtkE), an over half-century Florida resident of St. Augustine, Florida, claims that at one point they could be found no farther than Marineland, Florida, but are shown to be well-established in St. Augustine, and are now found "much farther north", so how recent is this?
