ABSTRACT

Many studies indicated that marine habitats and organisms in the Arabian/Persian Gulf ('Gulf') are broadly deteriorating. However, this likely results from the generalization of a few declining habitats or organisms in some locations. Here, we conduct a review to evaluate the status of selected habitats (mangroves, seagrasses, and coral reefs) and organisms (exploited bony fish, sharks, rays, dolphins, whales, and dugongs) and identify major threats to them in each Gulf country (except Iraq and Oman). We show that out of 52 habitats and organisms in the six countries, the predominant status (63.5%) is "Data-deficient", followed by "Decline" (21.2%) and "Increase-stable" (15.4%). The major threats to these habitats and organisms are coastal development, desalination plants, climate change, and fishing. However, our findings differentiate that some of these threats are causing severe degradation (i.e., have "Observed" impacts) while other threats, such as desalination plants, have potential impacts that are derived from laboratory experiments or modelling work. Our results can be used to guide conservation efforts in the region.
