Episode 302: Reef Revival

In the emerging science of coral reef restoration, marine biologists and resource managers are discovering naturally occurring mechanisms that promote coral growth and restore ecological balance in these gardens of the sea.

Since the late 1970s close to 98% of Staghorn and Elkhorn corals have disappeared from reefs in Florida and the Caribbean. Around the world, damage from boat groundings and other factors have placed these organisms on the “threatened” list of the Endangered Species Act. Staghorn and Elkhorn are considered principal reef building corals. In South Florida, scientists are using native sponges and spiny sea urchins in novel ways that may help attract corals to damaged sites. Can nature heal itself with a little help from marine experts? Can new technologies help restore the lost coral communities?
