Are native and nonindigenous seaweeds overgrowing Florida's east coast reefs?1

Charles Jacoby, Brian LaPointe, LeRoy Creswell2

The reefs found in the Atlantic Ocean off southern Palm Beach and northern Broward counties appear to be under threat. Since 1990, scientists have recorded a series of algal blooms that covered these reefs. Initially, the blooms comprised native species, but in 2001, scientists discovered a bloom of an introduced algal species. This fact sheet explains the history of observations, discusses what may be driving the observed changes, and suggests how we can help reverse or prevent damage to the reefs.
