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)
