Study Notes
Coral Reef Conservation in Fiji
- Fiji has been struggling to conserve its coral reefs for the past 20 years.
- Two-thirds of the reefs are considered at risk.
- The coral reefs are of significant environmental and economic importance to Fiji.
Human Impacts on Coral Reefs
- Overfishing and boat/anchor damage have negatively impacted the reefs.
- Fiji used to be a major exporter of coral and fish for aquariums.
- Tourist activity, including walking on the reefs and diving/snorkeling, has caused damage.
- Rapid population growth in coastal areas has increased the amount of pollutants entering the reefs.
Natural Impacts on Coral Reefs
- Cyclones cause destructive waves that damage the reefs every 3-4 years.
- Cyclones bring in nitrates and phosphates from agricultural runoff, which increases the number of Crown-of-Thorns starfish that feed on coral polyps.
- El Niño events cause warmer water temperatures, leading to coral bleaching.
- Bleaching causes the death of algae that live with the polyps, leaving the coral white and eventually causing the polyps to die as well.
- Lower salinity levels also contribute to coral bleaching.
Significance of Coral Reefs to Fiji
- Coral reefs boast high biodiversity with over 300 species of coral and 2,000 species of fish.
- They provide vital protection from storm waves.
- The reef ecosystem is being researched as a potential source of new medicines.
- The reefs are critical to Fiji's economy through fishing and tourism.
- Coral reefs hold deep cultural significance for the Fijian people, and traditional practices once helped regulate their use.
The Hide-away Resort Conservation Efforts
- The resort promotes awareness about the importance of the reef, and provides educational opportunities for visitors.
- The area directly in front of the resort is a protected zone with restricted access.
- Snorkeling is allowed at high tide, but walking on the coral is prohibited.
- A designated reef path is provided for guided walks.
- Visitors can observe marine life from a glass-bottomed boat.
- A coral nursery is maintained in the lagoon to cultivate and protect coral.
- Notices throughout the resort remind visitors about the importance of coral reef conservation.
Threats to Coral Reefs Globally
- Coastal development
- Pollution
- Sedimentation
- Overfishing
- Walking on the reef
- Natural disasters
- Eutrophication
Eutrophication Impacts
- Eutrophication is an enrichment of water bodies with nutrients, leading to excessive algal growth and the depletion of oxygen.
- This process disrupts the delicate balance of the reef ecosystem, causing significant harm.
