Parameters monitored
Benthic covers: Living and non-living substrata Reef fishes: Reefcheck and local indicators. Macro-invertebrates: Reefcheck indicators. Impacts: Physical indicators (dynamite, anchoring,
coral bleaching, COTS, Drupella snails).
-
Change in condition of coral reefs between time
-
Decline in hard coral cover from 1994 to 2012
-
Overall interval decline in hard coral cover
between periods of time
-
Estimation of changes in reef conditions
between 1994 and 2012
-
Impacts to coral reefs
Overfishing Destructive fishing Sedimentation and pollution Aquaculture development Tourism development Outbreak of predators (COTS, snails) Bleaching & red tides
