SURVIVAL RATES:
(1) relocation area under stress due to new construction developments.
Relocated Contractual % Achieved
SEAGRASS 10.000 m² 30% 53% - trend down(1)
MANGROVES 4.200 trees 80% 100% (6.100 trees)
HARD CORALS > 10.000 60% (> 3 years) 72%
SOFT CORALS 572 colonies N.A. 40%

CONCLUSIONS – TAKE AWAYS:
Relocation is a good mitigation measure if sensitive areas in footprint of marine activities
Relocation techniques;
do exist
are relatively successful with survival rates above expectations
their cost for this size of project is acceptable
Key to success:
Upfront site familiarization (baseline) wrt seasonal effect on ecosystem health
Careful selection of relocation area
Timing of relocation
Pro active & pragmatic involvement of Environmental Public Authority (Ministry of Environment)
