[Coral-List] Data on reef restoration costs

Fri Feb 27 08:55:09 EST 2004

Dear listers,

Following on from Gregor's email, I'm in the process of writing an updated
paper on the economics of coral restoration for Bill Precht's forthcoming
book on coral restoration.  

If anyone has any recent published or unpublished examples of coral
restoration activities with basic data on relevant resource use implications
(e.g. type and volume of resources used, costs, person hours, equipment
needed etc), then please get in touch.  Restoration activities could include
the options Gregor mentioned, plus any alternatives.  It would be great to
include a broad range of costed alternative approaches in the paper.  

Many thanks
James

accretion

Todd has raised an interesting point. It would be quite interesting to see a
cost comparison of coral cover produced over five years on a typical 5 km
long by 100 m wide reef using:

1) Natural recovery
2) Enhanced recruitment (larval reseeding)
3) Manual transplantation of coral fragments
4) Reef Balls etc.
5) Mineral accretion.

The vast majority of reefs that have suffered physical damage or loss of
living coral cover do not lack hard substratum. In fact, hard sea bed is
usually abundant. Artificial reefs, when combined with MPAs, are useful
tools to add hard substrata and to add habitat, particularly on soft seabed
far from coral reefs. With rare exceptions such as a ship grounding in front
of a resort or in a small MPA, is it a wise use of limited funding for reef
conservation to invest in contructing artificial substrata?

A coral restoration system implies that the ecosystem will be returned to
its original state before disturbance. Which of the methods listed above can
do this?

There are more practical(and cost effective)  ways to accomplish your
goals....for example, see
http://www.reefball.com/map/antiguascience/antiguapressrelease.htm for the
most advanced coral restoration system in the world.
