Site summary
Read this summary in:

An Al Qunfudah reef with more standing structure than its neighbor, including waist-high candelabra Acropora a couple of meters across and staghorn thickets over tiers of plating corals. Condition is the story, with much of the branching framework stark white or bone-pale and about 18% of coral tissue bleached under heavy heat stress in August 2024.

Site description

General benthic features

This one has more standing structure: elegant branching and arborescent Acropora colonies stand clear of the substrate, one of them a broad, waist-high candelabra a couple of meters across and stands of thinner staghorn thickets run along the reef top (e.g., Image 1, Image 2).

Beneath and around them the pavement is a dense mosaic of plating and foliose colonies stacked in overlapping tiers, low domes, red, and purple encrusting sponges, and crustose coralline algae, with the reef top falling away as a steep terraced slope studded with table colonies into blue water (e.g., Image 3, Image 4).

Coral cover

Published CoralNet point counts give 17% total coral cover (bleached included) against 8.5% algae, with 18.1% of coral tissue bleached at roughly 20.4 degree-heating-weeks - a manual point count from Anderson's own published paper, not a computer vision estimate. Also on record for this site: It carries the provenance of the paper it appears in and is not subject to the CoralSCOP/DINOv3 caveats applied elsewhere on this map.

Stressors

But the condition is the story: much of the branching framework in the frame is stark white or bone-pale, plating colonies show blanched leading edges, and the bright tan-and-cream corals stand in sharp contrast to those still fully pigmented. No crown-of-thorns starfish (COTS) or other corallivores evident.

Fish and other fauna

Snapper and small damselfish move over the top.
