LIVE INTERACTIVE LEARNING @ YOUR DESKTOP NOAA/NSTA Web Seminar: Coral Ecosystems: Land-based Pollution Threats to Coral Reefs Thursday, May 8, 2008
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
Outline • Coral biology • Value of coral reefs • Land-based pollution impacts • Management actions • Teaching resources
Outline • Coral biology • Value of coral reefs • Land-based pollution impacts • Management actions • Teaching resources
What is coral? Plant Both? Animal
Source: NOAA Coral is as an animal with an algal symbiont
Reef building corals require: • Warm water: 75 – 85 Fahrenheit degrees • Light: Shallow and sediment free waters • Salinity: 34 – 37 ppt PCS
Coral reef distribution Source: http://oceanservice.noaa.gov/education/kits/corals/media/supp_coral05a.html
Let’s pause for 2 questions
Outline • Coral biology • Value of coral reefs • Known effects of land-based pollution • Management actions • Teaching resources
Coral reefs are valuable • Biodiversity • Fisheries • Shoreline protection • Pharmaceuticals • Tourism • Education • Culture • Social values
Coral reefs: rainforests of the sea • How many species of fish live on reefs? • 40 • 400 • 4000 PCS
Reefs are important economically Hawaii: • Net benefits = $360 million year • Overall asset value MHI = $10 billion Study by: Cesar & van Beukering 2004
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
Let’s pause for 2 questions
Outline • Coral biology • Value of coral reefs • Land-based pollution impacts • Management actions • Teaching resources
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
Runoff impacts growth & survival of hard coral colonies Bill Walsh DAR
Any idea’s how runoff impacts coral growth and survival? Two volunteers?

Runoff effects coral reproduction & recruitment • Coral settlement rates are near zero on • sediment covered surfaces • Sediment tolerance is lower in new recruits
Runoff effects reef community structure Honolua Bay, Maui
Let’s pause for 2 questions
Outline • Coral biology • Value of coral reefs • Land-based pollution impacts • Management actions • Teaching resources
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
Sustainable Living Institute of Maui Hawaii’s Local Action Strategy: A collaborative multi-agency and community approach to protect Hawaii’s coral reefs
Taking action to: • Reduce pollutant loads • Increase understanding through scientific research & monitoring • Increase awareness
