What is A Reef?
Coral reefs are diverse ecosystems made of tiny living animals, called corals.
Corals are soft, stationary animals without a backbone!
When the corals die, they leave behind hard structures that are the basis of the reef
Home to 30 different kinds of whales, 6 kinds of turtles, and over 1500 kinds of fish, PLUS sea snakes, sharks, and stingrays!
Home to some of the largest clams in the world!
Microscopic algae live on the corals and through photosynthesis, the corals “steal” nutrients from the algau, giving them their vibrant colors
Angel Carney, 2010
Meet the Great Barrier Reef
Barrier Reefs are those that form parallel to a land mass, usually several miles away
Found in the shallow waters surrounding Queensland, Australia!
Named one of the seven wonders of the world!
Estimated to be 500,000Years old
It is the largest reef system in the world!
Over 344,400 square kilometers and 1,800 miles long!
1,200 miles long
Can be seen from space!
Angel Carney, 2010
Due to many outside influences, Great Barrier Reef is in peril!
It is estimated that by the year 2100, the world will have only 30% of it’s coral reefs
The Great Barrier Marine Park Authority has introduced several plans to help stop this
Lots of the species that are native to the Great Barrier Reef, and only found there are becoming endangered!
Endangered animals are species that are in danger of going extinct
Many of the species on the reef are exclusive to this area, which means when they are gone from the reef, they are gone from the planet
Angel Carney, 2010
The Problem: Endangered Species
The following are the chief concern of the Marine Park Authority. There are MANY other species in danger as well.
Sharks – whale shark, grey nurse shark, great white shark, freshwater and green sawfish
A summary of the status and future of the Great Barrier Reef
Provides a report of the management of the Great Barrier Reef
Summarizes the past and present management of the Great Barrier Reef
The GBR is one of the most extraordinary ecosystems in the world
Key issues to be addressed within the Park:
Declining water quality
Loss of habitat
Angel Carney, 2010
Great Barrier Reef is home to a VAST variety of species
No other place in the world is home to as many different plant and animal species living in harmony with each other
It is imperative that we preserve the diversity of this ecosystem
Aims to guide and help coordinate management actions that will protect and conserve biodiversity in the Great Barrier Reef, (GBRMPA, August 2010).
Conserves the diversity of the habitat as well as it inhabitants
Provides a framework for how biodiversity is managaged (GBRMPA, 2010).
Completes assessments on progress
Identifies problems, fall-backs, and prioritizes threats
Manufactures and distributes publications to the public
Angel Carney, 2010
Reef water protection plan
Launched in 2003, revised 2009
immediate goal - to halt and reverse the decline in water quality entering the Reef by 2013 (Qld Gov, 2009)
long term goal - to ensure that by 2020 the quality of water quality entering the Reef from adjacent catchments has no detrimental impact on the health and resilience of the Great Barrier Reef. (Qld Gov, 2009)
Implement strategies on the farms surrounding the area
Enact, Review, oversee and stay on top of policies
Angel Carney, 2010
Reef Protection Plan
Goal: To protect the Great Barrier Reef
Protects 33% of the reef from commercial and recreational fishing!
Identifies endangered species, and outlines steps to protect them
Allows native peoples to fish the reef
Prohibits removal of any part of the reef or any inhabitant
Angel Carney, 2010
Conclusion: The Great Barrier Reef has been recognized as a World Heritage Site. It covers an area larger than the size of Italy. Te Great Barrier Reef is home to a very wide variety of corals, polyps, plants, animals, fish, and more organisms and is more than 500,000 years old. It is imperative that we preserve this treasure trove under the sea. Many human practices are killing The Great Barrier Reef, but through knowledge we can spread the word and help combat the destruction of this natural wonder of the Earth. Please, help, spread the word! Angel Carney, 2010
