Artificial
Lighting and the Recovery of Sea Turtles

Florida
serves as an important developmental habitat for sea turtles, and hosts the
second largest loggerhead rookery in the world. This paper reviews the
historical decline of sea turtles in Florida, U.S.A., and the recent evidence
that suggests a modest recovery. ASEAN countries and Florida have in common that
they are experiencing rapid coastal development. In Florida artificial lighting
from coastal communities is an important source of hatchling mortality, and
probably constricts the location of major nesting sites to the few remaining
dark beaches. ASEAN countries can plan now to avoid these problems by developing
national light management plans. Central to such a plan is protection of the
present major rookeries ('core areas'). At these sites, lighting should be
entirely excluded not only from the beach, but also from areas behind the beach
in the form of a buffer (no development) zone. Such areas should be established
as preserves, perhaps supported by ecotourism. The facility at the Malaysian
Turtk Islands Park in Sabah can serve as a good model. Smaller rookeries located
near existing coastal communities can be protected by well-established light
management techniques. By planning now, ASEAN countries can avoid Florida's
mistakes, which necessitate expensive and labour-intensive efforts to protect
rookeries. They will also be in a better position to both protect and sustain
their sea turtle resources for future generations. |
