|Abstract: ||The potential environmental impacts of the development of a coral
propagation project on the island of H.A. Manafaru are assessed. Manafaru is
leased to Beach House Maldives and is operated by the Waldorf Astoria
collection of the Hilton group.
The assessment exposes the solutions and preferred alternatives as well as
mitigation measures to minimize any negative impacts whilst trying to derive
the maximum positive impacts from the project.
Manafaru has very little coral cover after being degraded by the 1998
bleaching event. As it is important to be proactive in reef restoration, the
resort management wishes to enhance the value of the island by propagating
corals using the coral frame technique.
The frames will be installed near the water villas and sparsely on the house
reef. Coral fragments will be attached by a marine biologist and will develop
into full colonies within a few years.
Coral fragments from the house reef will provide a small number of fragments
and will heal rapidly. Preference will be given to damaged colonies.
136 frames of 1m2 will be initially deployed, and after the first batch, the
existing frames will provide fragments for transplantation.
The project will start as soon as approval is granted, and as this is a long term
project, it could span several years before completion.
The island of Manafaru is located inside the northernmost atoll of the
Maldives, and is subject to high winds and warming waters, which may be a
cause of low coral survival.
As the island is located in the middle of the atoll, the waves reaching its
shores are diffraction of swells, and wind waves.
As the energy encountered are of second magnitude, and the reef does not
form a proper crest, the waves reach the island with less obstruction than
Sand displacement depends on the predominant influence during different
monsoons, forming a bulging beach rather than a sand tip.|
