Part of the regional summaries: Maldives - North (Haa Alif to Baa / Lhaviyani) and Maldives

A Baa Atoll reef that Anderson's January 2016 field notes describe as having very high coral cover and diversity, with whorled plate corals and lilac-tipped staghorn thickets — photographed just before the 2016 El Niño bleached most of the atoll's reefs. Coral Reef CPR point-intercept transects put cover at 27% in July 2016, after the bleaching, down from 74% in April 2016.

A reef Anderson's field notes describe as having "very high coral cover and diversity" — a rolling slope smothered in coral, where giant rosettes of thin, whorled plates stack like heads of ancient roses beside dense staghorn thickets with lilac-blue branch tips (e.g., Image 6, Image 18, Image 23, Image 24).
A vivid yellow-green table coral crowns one rise, and deeper down the reef turns into a waving green meadow of long-polyped colonies (e.g., Image 37).
In January 2016 Anderson's sample sheet already noted "some partial mortality" on three of the large branching colonies sampled (one also with "some new mortality") and "some paler sections" on another sampled colony. The frames from that dive also show stark-white sections on branching colonies, recent mortality, cause not stated (e.g., Image 46).
Months later, the 2016 El Niño bleached the vast majority of corals on Baa's reefs. No crown-of-thorns starfish (COTS) or other corallivores were evident.
Clouds of slender silver fish stream over the thickets (e.g., Image 17), damselfish hold territories among the plates, and a scarlet feather star hides in the branches.
Apart from the Coral Reef CPR surveys shown here, we found no other surveys at this site as of 2026. If you would like to share yours, please email us.
Look for the field marks of working science: numbered tags zip-tied to corals, a ruler laid against each tagged colony (e.g., Image 1, Image 2, Image 14), and a researcher's wrist computer reading 13.2 meters.
| Method | Hard coral cover (%) | Photos (n) ± SE |
|---|---|---|
| Transect, July 2016 (headline) | 26.6 | |
| Transect, April 2016 (during the bleaching) | 74.0 | |
| CoralSCOP edited | 26.2* | n = 19 · SE 5.3 |
CoralSCOP (edited photos) reads 26.2%, within 0.4 pp of the in-water transect (26.6%).
*Based on only 19 reef-habitat photos; this estimate is less certain.
