Marine protected areas are designated mostly for the purpose of protecting coastal and marine resources from human-induced impacts. Nonetheless, natural events can cause just as great, or greater, disturbances to an MPA ecosystem in a day or week than most human activities can. The worldís coasts are subject to a wide variety of severe natural hazards -- hurricanes, cyclones, tsunamis -- and MPAs are not immune from their impact. Natural climate variability, too, can cause significant shifts in species distribution, with die-outs of coral and other organisms.
These natural phenomena are inarguably a part of the ecosystems that MPAs are designed to protect, yet they can abruptly alter those very ecosystems and create real challenges for managers.
In light of the recent impact of Hurricane Lenny on the Soufrière Marine Management Area on St. Lucia (see next article), MPA News surveyed several experts for their thoughts on the role of natural hazard events and climate variability in MPAs. We also asked how managers could prepare for them.
