There are currently 14 records of A. cervicornis on the Vauxhall reef on iNaturalist. They were taken over the period 2015 – 2024 in the early months of the year (January to March or April, except in 2021 and 2022 when I did not visit Barbados). There are (apparently*) natural stands in the area, and also some cultured or transplanted specimens. In  April of 2023, all stands looked healthy, but were mostly dead when first examined in Jan or Feb of 2024; presumably mortality was associated with one or more of extreme warming coral bleaching events in 2023.

I began using iNaturalist to post species records from Barbados in 2019, but these observations go back to early 2015.

*I say “apparently” because I was told verbally by one person who said she had worked with government that the “Staghorn Coral at Vauxhall was established by transplanting”, however, there appear to be no related publicly available records and what I call ‘Natural Stands’ are very similar to those I observed in the 1960s. On the other hand, nor are there, it appears, any publicly available records of what are obviously transplants or cultured corals at Vauxhall; these occur in shallower waters/sandier bottom than the ‘Natural Stands’, also on 2 pieces of wreck south of the ‘Main Wreck’. Mclean and Oxendford (2016) make no mention of artifically established A. cervicornis at Vauxhall.

My initial report on Acroporoids at Vauxhall, which I shared at the time with government and academic personnel in Barbados,  was in the form of  a Google Photo album: Acropora prolifera (fused staghorn coral) in Barbados MPA 2015 and an assocated web page: Photographs of the Fringing Reef in the Recreational Zone of the Folkestone Marine Reserve, Barbados 2015-2016

“Specimens apparently transplanted from adjacent natural populations in deeper water – view Map (last photo in the series, sites a,b,c,d are for natural populations, the z sites are transplants) and other entries for A. cervicornis in this project. (e.g. https://www.inaturalist.org/

) Some other apparently transplanted corals in the same general area are shown, some on rocks, some on a wreck. The specimens all looked firm and healthy. Approx depths 3-5 m below MLW”

C: CULTURED OR TRANSPLANTED STAGHORN CORALS IN 2023/ALL HEALTHY

C1  iNaturalist Observation 199590436
Feb 8, 2023 (Feb 17, 2024)
Lat: 13.1785 Lon: -59.6409 Accuracy: 10m
A cervicornis grown on A frames in an open sandy area circa 5 m depth at Vauxhall Reef (Barbados) Fully healthy on Feb 8, 2023. Viewed a year later mostly dead (see next category, D,  below). I believe these structures were not being maintained at this time. There were natural populations amongst Orbicella annularis in somewhat deeper water perhaps 50 m seaward. – see Category E below.

D. CULTURED OR TRANSPLANTED STAGHORN CORALS IN 2024/MOSTLY DEAD

Lat: 13.178991 Lon: -59.641249Accuracy: 8m
“A. cervicornis colony about 6 meters depth on railing of a wreck; colony dead, overgrown with algae etc. Also shown are photos of the same site and coral on Feb 3, 2023, when it was completely healthy. This colony may have been placed there by recreational divers, poss x-planted from natural population nearby. Apparent mortality in likely associated with one or more extreme warming/coral bleaching events in 2023.”

Lat: 13.178822 Lon: -59.641655 Accuracy: 12m

“At about 10 meters depth in Lewis’s (1960) Deep Water Communities, jusr seaward of fringing reef at Vauxhall, barbados. Amongst Madracis asperula and Orbicella annularis. Older, mostly dead coral can be seen below surface layer of mostly living A. cervicornis. This is a restricted area with A. cervicornis, not seen elsewhere at least in 2015 when Mclean & Oxendford published a report on Acroporas in Barbados “Mapping the return of acroporid corals on fringing reefs along the west coast of Barbados”

“In Lewis’s (1960) Deepwater Community, Vauxhall reef, amongst O. annularis, much of it with SCTLD. There appears to be no living A. cervicornis, in contrast to views of these communities 2015-2023, attributed to dieback associated with one or more extreme warming/coral bleaching events in 2023. Contrast with 2023 view https://www.inaturalist.org/observations/199597464

Towards inner edge of Deepwater Communities of Lewis 1960 & junction with Reef Front zone, amongst O annularis. Colonies appear completely dead, in contrast to views in early 2023; attributed to extreme warming/coral bleaching events in 2023.
