Site summary

A Port of Miami urban-corals site on the Star Island seawall, where Anderson sampled 10 Pseudodiploria strigosa colonies on 26 June 2019; the sample sheet records fish bites on one of them. The Urban Corals gene-expression study (Rubin et al. 2021) reports a separate collection of 9 colonies here on 14 February 2020. The photographs are mostly close-ups of the sampled colonies, plus lobsters under a ledge, and no coral-cover figure exists for this site.

Site description

Coral cover

Stressors

Anderson's sample sheet records fish bites (corallivory) on one sampled colony, STAR8 ('fairly large colony with fish bites').

Fish and other fauna

Two lobsters shelter under a ledge (e.g., Image 1).

Comparisons with other data

Rubin et al. (2021) is a coral gene-expression study and reports no benthic cover for this site.

Dive record

Anderson sampled 10 Pseudodiploria strigosa colonies here along the seawall on 26 June 2019 (the sample sheet, STAR1-STAR10; the log: 'We found 10 target species colonies in just over half an hour along the sea wall') (e.g., Image 4, Image 5).

The Urban Corals study reports a separate collection at this site: tissue from 9 P. strigosa colonies on 14 February 2020 (Rubin et al. 2021, Frontiers in Marine Science 8:695236).

Other notes

The photographs that survive describe those sampled colonies, not the reef.

Independent surveys nearby

Within 5 km, 3 independent survey stations recorded hard coral cover in 2024. Since 2021, station-year means average 1.3% (range 0.0–4.0%; n = 3 station-years from 3 surveys).

Collected by other programs using different methods (NOAA rows come from NOAA monitoring programs (NCRMP, PIFSC, NCCOS), and each row's method is in its hover text), so these are context for the figures above, not a like-for-like comparison. Where a station was surveyed more than once, the cell shows either the range of its values or, as a single value, the mean of surveys made in one year. Station names are not dive-site names.
