来自 21 条永久标记线样线的数据显示，1975 年至 1982-1983 年间，卡里斯福特礁的珊瑚群落组成发生了重大变化。 0 至 9 m 之间的珊瑚种群显示出变化的迹象，主要是由于物理干扰，而生活在 10 至 21 m 之间的珊瑚数量由于沉积和疾病而减少。一些物种没有表现出变化的迹象，而另一些物种的垂直分布似乎正在发生变化和/或平均菌落大小显着减小。观察到的造礁珊瑚物种多样性和均匀度下降表明卡里斯福特礁的活力在 1975 年和 1982-1983 年间下降。
Data from 21 permanently marked line transects showed that significant changes occurred in the composition of the reef coral community on Carysfort Reef between 1975 and 1982-1983. Coral populations between 0 and 9 m show signs of change due primarily to physical disturbance while corals living between 10 and 21 m have decreased in abundance as a result of sedimentation and disease. Some species show no signs of change while others appear to be undergoing shifts in their vertical distribution and/or significantly decreasing in mean colony size. Observed decreases in species diversity and evenness of the reef-building corals suggest that the vitality of Carysfort Reef declined between 1975 and 1982-1983.
