  1. 2017 WIO Post-Bleaching Assessment Project 2nd November 2017 Mishal Gudka- mgudka@cordioea.net 10th WIOMSA Scientific Symposium

  2. Content • Objectives • Background • Plan • Activities and outputs • Data and analysis • Next steps

  3. Objectives Determine the extent of coral reef degradation in the Western Indian Ocean as a result of the 2016 coral bleaching event • To consolidate post-bleaching assessment methods and guidance for the WIO regional reef network • To capture and disseminate coral reef health data • To facilitate a meeting of regional stakeholders to share and present findings

  4. Background • 2016 - 3rd global coral bleaching event affected the WIO • IOC’s Biodiversity Project supported coral bleaching data collection for the 2017 GCRMN coral status report • Part of an initiative to enhance global efforts to assess the impacts of the 2016 coral bleaching event https://goo.gl/Wt6fbK

  5. Outputs and activities • Webinar conducted in July • Post-bleaching surveys September – October • Meeting of regional stakeholders - November • National assessment reports completed by December • Final report with regional synthesis - February 2018

  6. 2015/2016 WIO coral dataset (GCRMN coral status report) Project Plan • Communication with partners Survey sites with pre-bleaching data Data from institutions and organisations that independently collected post-bleaching data Fieldwork funded in Comoros, Kenya, Madagascar, Tanzania Data-sharing agreement Data summarised Summary data Updated WIO coral dataset with post-bleaching data

  7. Data • Coral reef data collected using standardized monitoring methods • Benthic • Quantitative 2016 bleaching • Fish abundance • Coral recruit • Coral condition

  8. Analysis plan National and regional scales: • Trend (decline/increase) in levels over time • Comparison of pre- and post-bleaching levels • Live hard coral cover • Recruit density etc. • Percentage of coral that died • Percentage of bleaching recorded (at peak)

  9. Final steps • Conduct data analysis – national and regional levels • Write national assessment chapters • Write regional synthesis • Complete and publish final report • Dissemination of key findings
