Black Forest – Namena Marine Reserve and Lomaiviti Group

Site Overview

Black Forest is a remarkable macro diving site within the Namena Marine Reserve, characterised by a sloping reef covered in massive gorgonian sea fans and soft corals that create a dark, forest-like canopy sheltering an extraordinary diversity of small marine creatures. The site takes its name from the dense growth of gorgonians whose dark branching structures, when viewed from below against the light, resemble the trunks and branches of a terrestrial forest. The gorgonian sea fans at Black Forest are among the largest in the reserve, with individual fans exceeding one metre in diameter and displaying intricate lattice patterns that serve as habitat for pygmy seahorses perfectly camouflaged to match their host polyps. Ghost pipefish drift among the gorgonian branches, their transparent bodies revealing internal anatomy and providing unique photographic subjects. Nudibranchs in numerous species graze on sponges and hydroids throughout the site, their brilliant warning colours adding splashes of red, yellow, blue, and orange to the predominantly green and brown reef palette. The sloping reef profile allows for a comfortable multi-level dive, starting deeper where the larger gorgonians grow and working up to shallower sections where soft corals and hard corals dominate. The mild current allows divers to hover motionless for macro photography without excessive finning that could disturb the delicate organisms. Cleaning stations on the larger coral heads attract small fish seeking parasite removal from cleaner shrimp and cleaner wrasse. Black Forest is often combined with Grand Central Station and Chimneys as part of a full-day diving itinerary in the Namena Marine Reserve, providing a complementary macro-focused experience to the pelagic action at the other sites.
