Abstract
|
Some coral reefs of the countries of the South Western Indian Ocean are showing recovery from
the coral bleaching event of 1998 that reduced live hard coral cover on many reefs to less than
5%. However, recent bleaching events and subsequent mortality of the new recruits are impeding
this recovery. Some exceptional sites are proving to be highly resilient to the bleaching damage,
while at other sites, anthropogenic stresses including excessive sedimentation, pollution and
trampling are compounding the effects of natural disturbances, such as cyclones, and increasing
reef degradation. There is considerable effort to increase the capacity to manage and to improve
decision making. It is encouraging that certain states are reporting increased resistance of
Acropora to coral bleaching, as these coral species are a critical component of the 3-dimensional
structure of reefs, and for creating complex habitats for fish and other reef species. The region
is described as a biodiversity ‘hot spot’, with a large number of endemic species. The number
of monitoring sites in the region has continued to increase, with the inclusion of some less
accessible sites, such as Tromelin, Juan da Nova, Europa (France) and Cosmoledo, Assumption
and Aldabra (Seychelles). These sites have been surveyed within the last 2 years to improve
the knowledge of the status of the coral reefs of this region over a larger geographical range.
Socio-economic evaluation of coral reef resources has been carried out in some states within
the last 2 years. The management of MPAs is being strengthened to increase the effectiveness of
conservation in the face of a predicted increase in frequency of coral-bleaching events.
100 Years ago: Most of the reefs in this region were pristine with very few adverse impacts
other than cyclones that were common during the summer months below about 10 degrees
South. There were low levels of exploitation of fish and other commercial species, however,
turtles and tortoises were harvested extensively.
In 1994: Many reefs were still relatively healthy, apart from areas where there were ports and
unregulated coastal developments. Reef management was largely undeveloped and there was a
general lack of awareness and political will for reef conservation.
