The Mesoamerican Reef One of the World’s Largest Coral Reefs
The Reef Itself • Nearly 1000 km long • Largest Reef system in the Americas • From Mexico to Honduras • More than 60 species of coral • More than 500 species of fish
Global Warming Impacts • Increased Ocean Temperatures • Caribbean Community Climate Change Centre (CCCCC) predict regional temperature increase up to 5oC by 2080 • CO2 dissolving in seawater making it more acidic • Increased number of storms and hurricanes
Consequences of Global Warming • Coral Bleaching- stress response • Loss of symbiotic algae that coexist with coral that provided food • Whitens coral • Results in disease, failed reproduction, partial/complete mortality of coral colony • Increase in coral and fish diseases • Acidic seawater slows marine organisms growth rate of shells and skeletons ex. Urchins, Coral • Anticipated reduction of effected marine organisms • Increased frequency of storms & hurricanes causes more floods and larger impact • Less recovery time for reefs- greater damage
Invasive Species- Lionfish • Believe population originated from aquarium in Florida, 1992 • Presumed to be largest predatory invasion in the Oceans • No natural predators in the Caribbean • Can lay as many as 1000 egg sacs per week • Eat herbivores • Herbivores important to reef- thin seaweed and cleam algae • Aggressive predator- venomous spikes • Believed that native fish do not yet recognize lionfish as dangerous
WWF Response- MAR Climate Change Project • Focusing mainly in Belize • 3 key elements • Science-based monitoring of climate change impacts on biological & social systems • Field level implementation of adaption strategies • An advocacy strategy to raise awareness of climate change and to lobby for climate change issues at local and national policy levels
WWF’s Implemented Improvements • Enhanced systems for reef monitoring • ‘Coral Reef Monitoring Group’ • Training local tour guides to identify bleaching • Creating Coral Nursuries to restore damaged coral quickly • Increasing awareness & understanding on the impacts on climate change • Plans to conserve mangroves • Develop private mangrove reserves • Adoption of drafts of National Climate Change Adaption Policy and National Adaption Strategy • Supporting development of local plans • National Sustainable Tourism Strategy • Coastal Zone Management plan
