在文檔中 The state of biodiversity in Kuwait (頁 24-33)

Located within the northeastern part of the Arabian Desert, Kuwait is characterized by flat to gently rolling open desert with very few minor elevations, wadis, depressions, some low dunes,

1 Introduction

coastal salt marshes and small off-shore islands (Halwagy et al., 1982; Halwagy & El-Saadawi, 1992).

From a geological point of view, the Gulf is a very recent sea. Resulting from the eastward migration

or four million years ago. The Gulf is one of the youngest bodies of water in the world and also one of the shallowest. The average depth is 36 meters, with a maximum depth of 90-100 meters along the Iranian coast. Due to the high evaporation (about Figure 2: Habitat of Jal Az Zour ridge (Photo from Abdulrahman Al-Sirhan).

is quite high. The water along the coast of Kuwait shows salinities of around 40 ppt, and along the Saudi Arabian coast between 35-40 ppt. However, in shallow water the salinity can become much higher. A salinity as high as 70 ppt has been reported in the Gulf of Salwah and in the inner parts of the Kuwait Bay. Tides in the area are basically semi-diurnal and vary from 2 to 3 meters along the Saudi Arabian and Kuwaiti coasts (Lindén et al., 2004; Omar et al., 2007).

Phasical parameters

The physical factors mainly in the form of extreme temperature fluctuations and elevated salinity exert considerable natural stress on the marine and coastal ecosystems of the Gulf. As a consequence, the biodiversity is significantly lower compared with the Indian Ocean. Because of the relative shallowness, the Gulf supports highly productive coastal habitats, such as the extensive intertidal mud-flats and seagrass beds. Along parts of the coast there are also areas of dwarf mangrove and coral reefs. However, the coral reefs show relatively very low biodiversity.

Many species of corals as well as other species of animals and several plants in the area live close to their tolerance thresholds. In the northern Gulf, most of the subtidal areas are soft sediment bottoms. Extensive seagrass beds mostly Figure 4: Arial photo from Al Jaharah Nature Reserve (Photo from Faisal Al Nomas).

cover these sediments, which supports a number of commercially important species such as the prawn. Algae mats associated with the tidal flats are also highly productive as they are covered

with blue-green nitrogen-fixating algae during part of the year. These tidal flats are a key feeding area for wintering and migrating waders (Lindén et al, 2004).
