29 May Saint Brandon, the largest algal ridge in the Indian Ocean

Saint Brandon comprises about 190 km2 (73 sq mi) of reefs. It has perhaps the largest algal ridge in the Indian Ocean. Coconut trees can be found on a few islands as well as bushes and grass. The islands are covered with white granular sand from eroded coral, and a thick layer of guano can be found in most places.

Coralline algae are red algae in the order Corallinales. They are characterized by a thallus that is hard because of calcareous deposits contained within the cell walls. The colours of these algae are most typically pink, or some other shade of red, but some species can be purple, yellow, blue, white, or grey-green.

Coralline algae play an important role in the ecology of coral reefs. Sea urchins, parrot fish, and limpets and chitons (both mollusks) feed on coralline algae. In the temperate Indian Ocean, coralline algae are the main builders of a typical algal reef. Many are typically encrusting and rock-like, found in marine waters all over the world.

In April 2016, The international conservationist Nathalie Boulle together with the Raphael Fishing Company Ltd., funded and organised a seven-day fact-finding mission by some of the world's experts. Three highly acclaimed international experts (Professor Henk Bauwman (Ecotoxicology, Environmental Pollution, Bird Ecology); Professor Tony Martin (world's foremost expert on marine mammals) and Dr. Nick Cole (herpetologist; MWF Islands Restoration Manager) inspected the islands to raise awareness about the need to protect the islands and to investigate, for the longer term, the effects of plastic and heavy metal pollution in the Indian Ocean.
