Benthic categories analyzed by the photoquadrat/CPCe method - Impact of the Marine Reserve of Reunion Island (RNMR) on biodiversity

the marine reserve of reunion island (rnmr) was created in 2007. in order to measure success of management goals, several methods of monitoring fish and coral populations are used. two protocols are used for monitoring fish populations : belt transects and timed swim. two protocols are used for monitoring coral communities : random swim to evaluate biodiversity and photo-quadrats along transect to evaluate the abundance of each benthic category. for this last protocol, photoquadrat are analyzed via cpce method (coral point count with excel extension).cpce is a visual basic software designed to calculate statistical coral coverage over a specified area. these images are being assigned with spatial random points for user’s further identification. it can also perform both image calibration and area analysis of the benthic features, and has the ability to automatically generate analysis in microsoft excel. customization options include user-specified coral/substrate codes and data point shape, size, and color. for this study, many benthic categories are analyzed and they are described into this file. datas are stored in the french database "bd recif" (developped by the french institute : ifremer).p0 campaign : began before the establishment of the reserve until the first years following the establishment (from 2004 to 2010) – 184 benthic categories were searched, and 170 were actually observed.p1 campaign : started in 2013 and ended in 2017– 197 benthic categories were searched, and 128 were actually observedp3 campaign : realized in 2021 – 102 benthic categories are listed and observed (be careful, do not rely on this list to know which categories are searched)for further informations about all the monitoring (fish and benthos protocols) and the results, please contact rnmr (report reference : bigot l., bruggemann h., audineau l., bureau s., chabanet p., cauvin b., dijoux g., durville p., guillaume m.m.m, haas j., hans r., mulochau t., penin l., rungassamy t., wickel j.

复岛海洋保护区（RNM）于2007年设立。为评估管理目标的实现程度，采用了多种监测鱼类和珊瑚群落的手段。针对鱼类种群监测，采用了两种协议：带状横断面和定时游泳。针对珊瑚群落监测，则采用随机游泳以评估生物多样性以及沿横断面设置的样方法以评估每个底栖类群的丰度。对于后一种协议，通过CPCE方法（珊瑚点计数及Excel扩展）对样方法进行分析。CPCE是一种基于Visual Basic的软件，旨在计算指定区域内的珊瑚覆盖率统计。这些图像被分配了空间随机点，以便用户进一步识别。该软件还能执行底栖特征的图像校准和面积分析，并具备在Microsoft Excel中自动生成分析报告的能力。定制选项包括用户自定义的珊瑚/基质代码和数据点的形状、大小及颜色。在本研究中，分析了众多底栖类群，并将它们描述在本文件中。数据存储在法国数据库“bd recif”（由法国研究院IFREMER开发）中。P0战役：始于保护区设立之前至设立后的最初几年（2004年至2010年）——搜索了184个底栖类群，实际观察到了170个。P1战役：始于2013年，结束于2017年——搜索了197个底栖类群，实际观察到了128个。P3战役：于2021年实施——列出了102个底栖类群并进行了观察（请注意，不要仅凭此列表了解搜索到的类群）。关于所有监测（鱼类和底栖群落的监测协议）及结果的相关信息，请联系RNM（报告参考：Bigot L.，Bruggemann H.，Audineau L.，Bureau S.，Chabanet P.，Cauvin B.，Dijoux G.，Durville P.，Guillaume M.M.M，Haas J.，Hans R.，Mulochau T.，Penin L.，Rungassamy T.，Wickel J.（2022）. 点2：关于复岛海洋自然保护区鱼类和珊瑚底栖群落的保护效果监测——RNM设立14年后的现状。最终报告，UR / UMR Entropie，为RNM而作。90页。）
