Coral reefs are shallow underwater habitats found in tropical

waters
Sometimes called rainforests of the sea, they form some of

Earth's most diverse ecosystems.
While coral reefs sustain about 25% of the ocean’s marine life, these wondrous ecosystems cover only 0.2% of the earth’s surface

Слайд 3Coral reefs
Great Australian Barrier Reef
the world’s most extensive coral reef

ecosystem
covers an area of 348,000 square kilometers
composed of over 2,900

individual reefs and 900 islands
stretches for over 2,300 kilometers
Corals of some 350 species live here

the largest barrier reef in the Northern hemisphere
The uniqueness of the Belize Barrier reef lies in the fact that this territory is composed of karst rocks and for many millennia has been drained several times and then again flooded by seawaters. This feature has provided inimitable variety of coral types combined with a specific marine landscape.
The most widely known karst landform on the site is the Big Blue Hole. Initially, the Blue Hole was a limestone cave that started to form about 150,000 years ago.

Слайд 5Shark Bay: three unique features
1) There is the largest sea

grass assemblage in the world with an area of 4800

square kilometers, thriving for the past 5000 years. Shark Bay contains the largest number of seaweed species ever recorded in a single location.

2) Sea grasses are the backbone of the food chain in shark Bay, providing a home and shelter for various marine species and attracting a population of dugongs: it is home to about 10,000 dugongs ("sea cows"), accounting for about 12.5% of the world's population

In addition to dugongs, it is home to Indo-Pacific bottlenose dolphins, green and loggerhead sea turtles, giant oceanic manta rays, and of course sharks. Whale shark is the biggest fish in the world that is feeding on plankton and reaching 60 feet long.

3) Stromatolites – colonies of algae forming hard, dome-shaped deposits, which represent the oldest form of life on Earth and are comparable to living fossils. Analogous structures dominated marine ecosystems for more than 3,000 million years.

Слайд 8The Sundarbans
The Sundarbans is a mangrove area in the delta

formed by the confluence of the Ganges, Brahmaputra and Meghna

Rivers in the Bay of Bengal.
The Sundarbans is of universal importance for globally endangered species including the Royal Bengal Tiger, Ganges and Irawadi dolphins, estuarine crocodiles and the critically endangered endemic river terrapin.

Слайд 9Wadden Sea
The Wadden Sea is the largest unbroken system of

intertidal sand and mud flats in the world. It lies

between the coast of northwestern continental Europe and the range of low-lying Frisian Islands.
The site covers the Dutch Wadden Sea Conservation Area, the German Wadden Sea National Parks of Lower Saxony and Schleswig-Holstein, and most of the Danish Wadden Sea maritime conservation area.

Слайд 10Natural System of Wrangel Island Reserve
Inscribed in 2004, it boasts

the world’s largest population of Pacific walrus, with up to

100,000 animals congregating in the island’s rookeries. Research suggests that some humpback whales from the Whale Sanctuary of El Vizcaino in Mexico migrate all the way to the waters around Wrangel Island for summer feeding, highlighting the connections between the Arctic Ocean and World Heritage sites in lower latitudes.
