Great Barrier Reef
Description
The Great Barrier Reef is a site of remarkable variety and beauty on the north-east coast of Australia. It contains the world’s largest collection of coral reefs, with 400 types of coral, 1,500 species of fish and 4,000 types of mollusc. It also holds great scientific interest as the habitat of species such as the dugong (‘sea cow’) and the large green turtle, which are threatened with extinction

As the world’s most extensive coral reef ecosystem, the Great Barrier Reef is a globally outstanding and significant entity. Practically the entire ecosystem was inscribed as World Heritage in 1981, covering an area of 348,000 square kilometres and extending across a contiguous latitudinal range of 14o (10oS to 24oS). The Great Barrier Reef (hereafter referred to as GBR) includes extensive cross-shelf diversity, stretching from the low water mark along the mainland coast up to 250 kilometres offshore. This wide depth range includes vast shallow inshore areas, mid-shelf and outer reefs, and beyond the continental shelf to oceanic waters over 2,000 metres deep.

The latitudinal and cross-shelf diversity, combined with diversity through the depths of the water column, encompasses a globally unique array of ecological communities, habitats and species. This diversity of species and habitats, and their interconnectivity, make the GBR one of the richest and most complex natural ecosystems on earth. There are over 1,500 species of fish, about 400 species of coral, 4,000 species of mollusk, and some 240 species of birds, plus a great diversity of sponges, anemones, marine worms, crustaceans, and other species. No other World Heritage property contains such biodiversity. This diversity, especially the endemic species, means the GBR is of enormous scientific and intrinsic importance, and it also contains a significant number of threatened species. Attime of inscription, the IUCN evaluation stated “… if only one coral reef site in the world were to be chosen for the World Heritage List, the Great Barrier Reef is the site to be chosen”.

Within the GBR there are some 2,500 individual reefs of varying sizes and shapes, and over 900 islands, ranging from small sandy cays and larger vegetated cays, to large rugged continental islands rising, in one instance, over 1,100 metres above sea level. Collectively these landscapes and seascapes provide some of the most spectacular maritime scenery in the world.

of the World Heritage area is made up of coral reefs. The rest is an extraordinary variety of marine habitats ranging from shallow inshore areas – such as seagrass, mangroves, sand, algal and sponge gardens, and inter-reefal communities – to deep oceanic areas more than 250 km offshore.
First and foremost, I would like to express my gratitude to all the online exhibition visitors who have taken the time to explore and learn about the Great Barrier Reef. Your interest and engagement in this vital issue are crucial for raising awareness and promoting conservation efforts. I am also incredibly thankful to my instructor for providing me with the valuable opportunity to design and develop a website dedicated to the Great Barrier Reef.
I am writing this letter to express my deep interest and motivation in choosing the Great Barrier Reef as the subject for my project after taking the Digital Promotion and Preservation of Heritage course. The course has provided me with valuable insights into the importance of preserving our global heritage and how digital technologies can play a significant role in raising awareness and promoting conservation efforts.
Throughout the course, I have become increasingly passionate about the intersection of heritage preservation and climate change. The Great Barrier Reef, as one of the most significant and biodiverse ecosystems on our planet, is a prime example of a natural heritage site that is under immense threat due to the impacts of climate change. I strongly believe that by focusing on the Great Barrier Reef as the topic for my project, I can contribute to the ongoing efforts to protect and preserve this vital ecosystem.
The project will not only help me deepen my understanding of the challenges faced by the Great Barrier Reef but also allow me to explore innovative digital solutions for promoting awareness and inspiring action. By showcasing the beauty and importance of the reef, as well as the urgent need to address climate change, I hope to engage a broader audience and encourage them to become advocates for the conservation of the Great Barrier Reef and other threatened heritage sites.
In conclusion, I am highly motivated and committed to using the knowledge and skills acquired in the Digital Promotion and Preservation of Heritage course to create a meaningful project that highlights the urgent need to protect the Great Barrier Reef. I believe that this project will help me further develop my expertise in heritage preservation and contribute to the global efforts to mitigate the impacts of climate change on our shared heritage.
Once again, I would like to extend my heartfelt appreciation to the online exhibition visitors and my instructor for their support and encouragement throughout this project. Your enthusiasm and dedication have truly inspired me, and I am looking forward to creating a project that can make a difference in the preservation of the Great Barrier Reef and other heritage sites around the world.
