Plant Animal Both?Coral is as an animal with an algal symbiont : Coral is as an animal with an algal symbiont Source: NOAAPowerPoint Presentation: Reef building corals require: Warm water: 75 – 85 Fahrenheit degrees Light: Shallow and sediment free waters Salinity: 34 – 37 ppt PCS Coral reef distribution: Coral reef distribution Source: http://oceanservice.noaa.gov/education/kits/corals/media/supp_coral05a.htmlPowerPoint Presentation: Let’s pause for 2 questionsOutline: Outline Coral biology Value of coral reefs Known effects of land-based pollution Management actions Teaching resourcesPowerPoint Presentation: Coral reefs are valuable Biodiversity Fisheries Shoreline protection Pharmaceuticals Tourism Education Culture Social valuesCoral reefs: rainforests of the sea: Coral reefs: rainforests of the sea How many species of fish live on reefs? 40 400 4000 PCSCoral reefs protect the shore-line: Coral reefs protect the shore-lineReefs are important economically: Reefs are important economically Hawaii: Net benefits = $360 million year Overall asset value MHI = $10 billion Study by: Cesar & van Beukering 2004Many threats to Coral Reefs: 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 DiseasePowerPoint Presentation: Let’s pause for 2 questionsOutline: Outline Coral biology Value of coral reefs Land-based pollution impacts Management actions Teaching resourcesLand and sea are connected: Land and sea are connectedPowerPoint Presentation: Photo’s courtesy of Malama MaunaluaMany sources of land-based pollution : Many sources of land-based pollutionPowerPoint Presentation: 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 threatens coral reefs globallyRunoff impacts growth & survival of hard coral colonies: Runoff impacts growth & survival of hard coral colonies Bill Walsh DARAny idea’s how runoff impacts coral growth and survival?: Any idea’s how runoff impacts coral growth and survival? Two volunteers? 1. 2.Sediments reduce light and decrease coral growth : Sediments reduce light and decrease coral growthPowerPoint Presentation: Sediments smother coral & sloughing wastes energy Photo’s courtesy of Bill WalshPowerPoint Presentation: Runoff effects coral reproduction & recruitment Coral settlement rates are near zero on sediment covered surfaces Sediment tolerance is lower in new recruitsRunoff effects reef community structure: Honolua Bay, Maui Runoff effects reef community structurePowerPoint Presentation: Let’s pause for 2 questionsOutline: Outline Coral biology Value of coral reefs Land-based pollution impacts Management actions Teaching resourcesManaging land-based pollution: 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.govPowerPoint Presentation: Hawaii’s Local Action Strategy: A collaborative multi-agency and community approach to protect Hawaii’s coral reefs Sustainable Living Institute of MauiTaking action to:: Taking action to: Reduce pollutant loads Increase understanding through scientific research & monitoring Increase awarenessOutline: Outline Coral biology Value of coral reefs Known effects of land-based pollution Management actions Teaching resourcesLesson Plans & Curriculum : Lesson Plans & Curriculum http://www.oceanservice.noaa.gov/educationPowerPoint Presentation: http://www.hawaiireef.net/teachers/teachers.shtmlPowerPoint Presentation: http://www.hawaiianatolls.org/teachers/NavChange.phpPowerPoint Presentation: http://www.epa.gov/adopt/resources/Activities: Activities http://www.sanctuaries.noaa.gov/education/ocean_guardian/welcome.htmlEducational materials: Educational materials International Year of the Reef http://www.iyor.orgPowerPoint Presentation: Other educational materials available from NOAA and NSTA Science Objects (4): Coral Reef Ecosystems Web Seminar Archives (2): Today’s and April 10’s SciPack: Coral Reef Ecosystems SciGuide: Coral Ecosystems Journal Articles http://learningcenter.nsta.orgFunding: Funding NOAA Bay Watershed Education and Training (B-WET) Program was established in 2002 to create environmentally literate students and teachers through education. http://www.csc.noaa.gov/psc/bwet.html http://www.sanctuaries.noaa.gov/news/bwet/welcome.htmlThank you : Thank youNASA logo: NASA logo Thanks to our presenter, Kathy Chaston and to NOAA for sponsoring this programElluminate logo: http://www.elluminate.com Elluminate logoNLC screenshot: http://learningcenter.nsta.org NLC screenshotPowerPoint Presentation: National Science Teachers Association Gerry Wheeler, Executive Director Frank Owens, Associate Executive Director Conferences and Programs Al Byers, Assistant Executive Director e-Learning LIVE INTERACTIVE LEARNING @ YOUR DESKTOP NSTA Web Seminars Flavio Mendez, Director Jeff Layman, Technical Coordinator You do not have the permission to view this presentation.
