Coral reefs degradation has occurred in many places throughout the Indonesia
archipelago, one which was in Puhawang Island of Lampung Province sited in N:
05o40’54” and S: 105o13’56” . Therefore, the coral reefs conservation program had been
introduced by the Ministry of Marines and Fishery, such as establishing the grouper
culture followed with artificial reefs in year 2001 and 2002, then once again in year 2006
for another artificial reefs transplanted with the life corals. The study then was conducted
to evaluate the existing coral reefs condition and to monitor the program activity, in year
2004, 2006, and 2007. The coral reefs condition was determined based on life-forms
method using Line Intercept Transect in two different depths, 5 and 10 meters. The coral
reefs were indeed had been preserved since the establishing of the program, it showed
that the coral reefs had been protected since then. The incentive which obtained from the
grouper culture has sustained the coral reefs conservation by the local community, in
which then it affected the coral reefs recovery from degradation. However, the
recruitment of the corals in the previous implanted artificial reefs (for the last 5 years)
monitored from 2004 – 2006 was considerably slow; it covered 50.42% of the total
artificial reefs area, 38.75% of was covered by hard corals and 11.67% was
sponges/tunicates. We conclude then that the coral reefs conservation by establishing the
grouper culture was able to give community benefits and the implementation of artificial
reefs would be considered to improve the coral conservation.

The Vieques Island Coral Reef Restoration Demonstration Project is an outgrowth of the
National Oceanic and Atmospheric Administration’s (NOAA’s) efforts, as a natural
resource trustee, to help facilitate the cleanup, protection and restoration of the coastal
resources of Vieques Island, Puerto Rico. The Navy began using Vieques Island in the
early 1940s for naval gunfire and support and air to ground ordnance training. The Navy
is now investigating areas it previously occupied to determine the extent of any potential
contamination and to remove any unexploded ordnance (UXO) and ordnance related
debris. To date, these activities have focused primarily on land but future efforts will
investigate the magnitude and extent of ordnance and debris underwater and the potential
impacts removal of these items may have on coral reefs. The Vieques Island Coral Reef
Restoration Demonstration Project is designed to evaluate the success of various types of
artificial reef structures to restore coral reefs. The design is based on addressing many
aspects of reef function, not just charismatic species such as hard corals, and involves the
integration of both natural and artificial structures into the natural reef ecosystem. The
artificial reef structures were placed off the coast of Vieques Island during August 2007.
The settlement of corals, survival of coral transplants, and use of the structures by other
sessile and mobile reef organisms will be monitored quarterly for a two year period.

The Coral Transplantation Experiment Contributes A Tool For Rehabilitation Of
Degraded Coral Reefs In Ha Long Bay Natural World Heritage Site, Vietnam

The coral reefs in Ha Long Bay have suffered from several sources of damage such as the coral
bleaching event of 1998, as well as destructive fishing practices. To addess some of these
problems an experiment coral transplantation works was carried out with the total area of
transplanted reefs covered 400m2. The substrates used for coral transplantation were made from
cement, metal and PVC tubes. The results of this experiment after one year of operation
(January 2005 to December 2005) indicated that low cost techniques of coral transplantation
have contributed to coral reef restoration in Ha Long Bay. The survival rate of coral colonies at
transplanted sites reached 85-90% and the branching coral, Acropora spp,performed very well
in all the substrate types. No significant differences were found in the survival rates of coral
colonies among substrates. There were significant changes in reef fish species indicators within
and outside transplanted reefs. For example, most juvenile cryptic species such as Chaetodon
octofasciatus and Cephalopholis boenack were more abundant in transplanted reefs compared
with natural reef sites. The outcomes of this work have increased public involvement, with local
organization taking part in conservation of coral reefs in recent years.
