Biodiversity of the Blue Lake

The Blue Lake is not only a place of legend: it is an ecosystem of unsuspected richness. Its calm waters and enclosed situation between coconut grove and lagoon make it a refuge for numerous species.

Fauna and flora

• Birds: kingfishers, egrets, grey herons nest in the surrounding trees
• Fish: tilapia and carp populate the waters, though fishing is limited out of respect for the site's sacred character
• Aquatic flora: water lilies and water hyacinths partially cover the surface during the rainy season
• Coconut trees: the grove surrounding the lake creates a cool microclimate ideal for walking

Threats and preservation

Several factors threaten the lake's balance:

• Sand extraction for construction, which modifies the lake's depth
• Plastic waste carried by the lagoon during floods
• Increasing tourism without a regulatory framework

Faced with these challenges, local communities have initiated a monthly bank cleanup program, supported by local associations. A project to classify the site as a protected natural area is under study by the Lacs 1 municipality.
