Coral Reef Evaluation and Monitoring Project Florida Keys 2001

The purpose of the Coral Reef Evaluation and Monitoring Project (CREMP) is to monitor the status and trends of selected reefs in the Florida Keys National Marine Sanctuary(FKNMS). CREMP assessments have been conducted annually at fixed sites since 1996 and data collected provides information on the temporal changes in benthic cover and diversity of stony corals and associated marine flora and fauna. The core field methods continue to be underwater videography and timed coral species inventories. Findings presented in this report include data from 109 stations at 37 sites sampled from 1996 through 2008 in the Florida Keys and 1999 through 2008 in the Dry Tortugas. The report describes the annual differences (between 2007 and 2008) in the percent cover of major benthic taxa (stony corals, octocorals, sponges, and macroalgae), mean coral species richness and the incidence of stony coral conditions. Additionally, it examines the long-term trends of the major benthic taxa, five coral complex, Montastraea cavernosa, Colpophyllia natans, Siderastrea siderea, and Porites astreoides) and the clionaid sponge, Cliona delitrix.珊瑚礁评估与监测项目（Coral Reef Evaluation and Monitoring Project, 简称CREMP）旨在监测佛罗里达礁岛群国家海洋保护区（Florida Keys National Marine Sanctuary, 简称FKNMS）内选定珊瑚礁的现状与变化趋势。自1996年起，该项目便在固定监测点位开展年度评估，所采集的数据可反映石珊瑚（stony corals）、相关海洋动植物的底栖覆盖度（benthic cover）与多样性的时间动态变化。核心野外调查方法始终采用水下摄像法与定时珊瑚物种清点工作。本报告呈现的研究结果涵盖1996年至2008年间在佛罗里达礁岛群37个监测点的109个采样站位数据，以及1999年至2008年间在德赖托图格斯群岛的采样数据。报告阐述了2007年与2008年间主要底栖分类群的覆盖百分比差异，涉及石珊瑚、八放珊瑚（octocorals）、海绵（sponges）与大型藻类（macroalgae），同时给出珊瑚物种平均丰富度以及石珊瑚健康状况的发生情况。此外，本报告还分析了主要底栖分类群、五种珊瑚复合体（包括巨腔滨珊瑚（Montastraea cavernosa）、脑纹珊瑚（Colpophyllia natans）、星群珊瑚（Siderastrea siderea）以及华丽孔珊瑚（Porites astreoides））以及穿贝海绵（Cliona delitrix）的长期变化趋势。
