Endangered sea turtles and coral reefs of the Gulf

The Gulf provides habitat for five of the planet's seven marine turtle

species. It also supports coral reefs, West Asia accounting for eight per

cent of the world's mapped reefs.

While these contribute substantially to marine biodiversity, ground reality

is that both turtles and reefs are as gravely threatened in this region, as

they are the world over.

 

All five turtle species fall into either the endangered or critically

endangered categories; and two-thirds of the Gulf's coral reefs are

classified as at risk. With threats persisting and growing, EWS-WWF

considered it important for concerned nations to congregate and strategize

about the region's marine biodiversity.

 

At the Marine Conservation Forum held on September 11 - 14, 2006 in Abu

Dhabi, over 80 marine experts, government officials, and environmental NGOs

from the Gulf Cooperation Council (GCC) countries, Yemen, Iran and Eritrea

gathered in the UAE capital to deliberate on the region's sea turtle and

coral reef resources, the perils these face and possible conservation

solutions.

 

The format of the Forum, which started off with experts sharing an

international perspective on conservation efforts, followed by country

presentations and break-out sessions for smaller focus-groups, was highly

conducive to learning and interaction.

 

Sea turtles

The hawksbill turtle (Eretmochelys imbricata) and green turtle (Chelonia

mydas) regularly occur in the waters of the Gulf and Arabian Sea. Loggerhead

(Caretta caretta), olive ridley (Lepidochelys olivacea) and leatherback

(Dermochelys coriacea) turtles are also spotted. All species, other than the

leatherback, nest in the region.

 

Nesting beaches occur in the UAE, Qatar, Kuwait and Iran, but the finest are

found along the coasts of Oman and Yemen. In Oman, an estimated 30,000

loggerhead turtles nest on Masirah Island each year, making this possibly

the world's largest nesting ground for the species, while some 13, 000 - 20,

000 annual nesting female green turtles congregate on Ras Al Hadd and Ras Al

Jinz. Loggerheads also nest along Socotra Island in Yemen, which

additionally hosts some of the Arabian Peninsula's most important nesting

beaches for green and hawksbill turtles on the Sharmah - Jethmoon coast by

the Gulf of Aden.

 

Coral reefs

Coral habitats (with patch, platform and fringing reefs) surround major

islands and offshore banks in all countries of the Gulf. It is not

surprising that the best coral ecosystems are also where the greatest turtle

populations occur - Yemen and Oman coasts, where reefs provide ample

foraging grounds. About 10 per cent of Oman's 300 km coastline, abutting the

Arabian Gulf, Gulf of Oman and Arabian Sea, supports reef-forming corals at

locations including Musandam Peninsula, Masirah Island, Mirbat-Salalah and

Damaniyat Islands.

 

It is, however, Yemen's reefs (Red Sea and Gulf of Aden) that are the jewels

in the crown. With 253 stony coral species, Socotra archipelago is one of

the richest sites for reefs in the western Indian Ocean. Extensive and

diverse coral growth is also observed along the Red Sea coast of the

country.

 

In the course of the Forum, there was an astonishing revelation from Iran:

The presence of soft coral. Past research had ruled out the presence of soft

coral in the Gulf. Surveys in 2004, however, revealed three genera of soft

coral from seven Iranian islands, including some new records for the Gulf.

 

Threats

Marine biodiversity in the region faces extensive threats. One recent and

most damaging threat to turtle and coral habitats in almost all Gulf states

is the unprecedented pace of construction along, and off, the coastline.

Destructive and wasteful fishing is another.

 

If turtles are falling prey to shrimp trawlers in Bahrain and entangling in

gill nets along Qatar, then coral reefs of Oman are getting smothered by

abandoned fishing gear and those in Kuwait being crushed by boat anchors

carelessly dropped on them. If it is coral collection for ornamental use in

Iran and coral fishes for the aquarium trade in Yemen; it is turtle eggs for

consumption in Qatar and four wheel drive - vehicles on turtle nesting

beaches in the UAE.

 

And there are more: marine pollution (oil, litter, other debris), thermal

effluents, human encroachment on beaches, insufficient data information,

absence of scientific expertise… the list of threats seems endless.

 

But perhaps, the most bemoaned is the lackadaisical enforcement of

environmental laws and regulations in most states. Rarely are projects

halted, or even modified, following an environmental impact assessment

report. Developers, in most cases, exercise greater influence on decision

makers than the environment protection authorities!

 

Undoubtedly, these shared species of the Gulf are gravely imperiled.

 

Conservation action

Some efforts are, nevertheless, being made towards marine biodiversity

conservation. Such as turtle tagging to study their migration; coral reef

surveys and research; fisheries bycatch reduction (Bahrain is testing a BRD

- Bycatch Reduction Device); establishing artificial reefs to compensate for

destroyed natural reefs and others. There are Marine Protected Areas too,

e.g., Marawah and Al Yasat (UAE), Damaniyat Islands (Oman), and Dihamri

(Yemen).

 

Delegates at the Forum felt, however, that far more needs to be done if

marine biodiversity is to be protected: establish more Marine Protected

Areas strengthen enforcement laws and regulations related to natural

resources and, significantly, reform the environmental impact assessment

process. Additional recommendations include greater stakeholder input into

decision-making and improved collaboration and communication between

national and regional conservation organisations.

 

If anything can steer these recommendations towards action, it is sustained

dialogue between the region's environmental agencies, which the Marine

Conservation Forum has successfully initiated.
