"Staghorn, elkhorn coral reefs rebounding in Florida Keys"

Every August or September on nights following a full moon, divers descend into the dark, warm waters off the Florida Keys to watch group sex — a fascinating reproductive eruption known as the annual coral spawn.



Okay back to the issue:



This year's spawn was particularly thrilling for scientists working to restore two important and vanishing species, staghorn and elkhorn coral, which formed the foundation of barrier reefs from Florida to the Caribbean until massive and mysterious die-offs over the last 30 years.

For the first time, stands of "farm-raised" staghorn transplanted to Molasses Reef off Key Largo were caught in the act, providing critical proof that corals cultivated in underwater nurseries can not only survive but do the wild thing.

For researchers, it has raised optimism that they might actually have a shot at slowing, maybe even reversing, decades of staggering loss. Staghorn and elkhorn — large and spectacular branching corals that once grew in sprawling forests — have declined by as much as 97 percent along a reef tract stretching from Palm Beach to the Dry Tortugas.

"This is the future of reef restoration," said marine biologist Ken Nedimyer, who helped pioneer coral cultivation in two nurseries he tends off the Upper Keys.

RECOVERY PLAN

In 2006, the two corals were the first to be designated as federally threatened. Under a recovery plan still being written, the National Oceanic & Atmospheric Administration recently gave $4 million in stimulus funding to expand fledgling underwater nurseries off Broward County, in Biscayne National Park, the Keys and the Virgin Islands.

``Even if we spend years and millions of dollars, our footprint will be very small,'' said Lirman, who is managing a nursery in Biscayne National Park.

``The only way for large-scale recovery to happen is through establishing sexually productive corals,'' he said. ``They spawn. The gametes [sperm-and-egg bundles] are broadcast into the water column. They can travel for miles and miles and settle on faraway habitats.''

Very cool story. Coral Reefs play a very important roll in the health and diversity of life in the oceans and such techniques create hope that we will be able to mitigate the impacts of shrinking coral reefs.

I personally am very fond of such stories where humans find ways to act as stewards of the planet, where we develop technologies that benefit the planet which in turn benefit us.

I believe that this is the roll we were intended to play on the Earth, first to protect and second to heal the planet that we are an inseparable element of.

Wonderful. I'm glad we're finally restoring something beautiful that we destroyed originally. Our reefs are some of the most beautiful things on the planet and we've put them through hell with pollution, overharvesting for ornamental purposes, and simply crashing into them with our massive ships.

Now more of us in the reefing hobby just need to learn to purchase these captive-bred corals as opposed to the ones some fisherman in indonesia pumps with cyanide and plucks off the reef. Same goes for the fish, o course. They're obviously just as good as the "wild" thing, if they're propagating in the ocean!
