  1. LIVE INTERACTIVE LEARNING @ YOUR DESKTOP NOAA/NSTA Web Seminar: Coral Ecosystems: Land-based Pollution Threats to Coral Reefs Thursday, May 8, 2008

  2. Land-based Pollution Threats to Coral Reefs Presented by Kathy ChastonCoral & Coastal Management Specialist NOAA’s National Ocean Service Office of Ocean & Coastal Resource Management

  3. Outline • Coral biology • Value of coral reefs • Land-based pollution impacts • Management actions • Teaching resources

  4. Outline • Coral biology • Value of coral reefs • Land-based pollution impacts • Management actions • Teaching resources

  5. What is coral? Plant Both? Animal

  6. Source: NOAA Coral is as an animal with an algal symbiont

  7. Reef building corals require: • Warm water: 75 – 85 Fahrenheit degrees • Light: Shallow and sediment free waters • Salinity: 34 – 37 ppt PCS

  8. Coral reef distribution Source: http://oceanservice.noaa.gov/education/kits/corals/media/supp_coral05a.html

  9. Let’s pause for 2 questions

  10. Outline • Coral biology • Value of coral reefs • Known effects of land-based pollution • Management actions • Teaching resources

  11. Coral reefs are valuable • Biodiversity • Fisheries • Shoreline protection • Pharmaceuticals • Tourism • Education • Culture • Social values

  12. Coral reefs: rainforests of the sea • How many species of fish live on reefs? • 40 • 400 • 4000 PCS

  13. Coral reefs protect the shore-line

  14. Reefs are important economically Hawaii: • Net benefits = $360 million year • Overall asset value MHI = $10 billion Study by: Cesar & van Beukering 2004

  15. Many threats to Coral Reefs Key threats to US reefs: • Over-fishing • Land-based sources of pollution • Recreational overuse/misuse • Lack of public awareness • Climate change & coral bleaching • Disease

  16. Let’s pause for 2 questions

  17. Outline • Coral biology • Value of coral reefs • Land-based pollution impacts • Management actions • Teaching resources

  18. Land and sea are connected

  20. Many sources of land-based pollution

  21. Runoff threatens coral reefs globally Models estimate that 22% of all coral reefs world-wide are at high or medium threat from inland pollution and soil erosion. (Bryant et al. 1998). USGS

  22. Runoff impacts growth & survival of hard coral colonies Bill Walsh DAR

  23. Any idea’s how runoff impacts coral growth and survival? Two volunteers?

  24. Sediments reduce light and decrease coral growth

  25. Sediments smother coral & sloughing wastes energy Photo’s courtesy of Bill Walsh

  26. Runoff effects coral reproduction & recruitment • Coral settlement rates are near zero on • sediment covered surfaces • Sediment tolerance is lower in new recruits

  27. Runoff effects reef community structure Honolua Bay, Maui

  28. Let’s pause for 2 questions

  29. Outline • Coral biology • Value of coral reefs • Land-based pollution impacts • Management actions • Teaching resources

  30. Managing land-based pollution • US Coral Reef Task Force formed • Addressing key threats to reefs is a national priority • Development of local action strategies More information: http://coralreef.gov

  31. Sustainable Living Institute of Maui Hawaii’s Local Action Strategy: A collaborative multi-agency and community approach to protect Hawaii’s coral reefs

  32. Taking action to: • Reduce pollutant loads • Increase understanding through scientific research & monitoring • Increase awareness

  33. Outline • Coral biology • Value of coral reefs • Known effects of land-based pollution • Management actions • Teaching resources
