Iranian Ship Oil Slick Threatens Gulf's Hara Biosphere Reserve

An oil slick from a damaged Iranian drone carrier, the Shahid Bagheri, is threatening to contaminate the Hara biosphere reserve, one of the Middle East's most important wetlands. The slick was caused by a US warplane attack in early March, which left the ship leaking heavy fuel oil in Iranian territorial waters near the Strait of Hormuz.

The oil has slowly been moving westwards towards the Hara biosphere reserve, the largest mangrove forest on the Gulf shoreline. By 18 March, the oil had traveled 16 miles southwest in the direction of Hara, according to satellite image analysis. The spill could be the most ecologically significant in the region since the first Gulf War.

The Hara reserve is an important ecosystem for migrating birds and critically endangered turtles, as well as many species of fish and crustaceans. The region's fishing communities depend almost entirely on the sea for their livelihoods, making the potential impact of the spill significant.

Environmental analysts have expressed concern that the situation could worsen if attacks on oil and chemical tankers continue. Wim Zwijnenburg, an environment analyst, noted that “if you keep shooting at oil [and] chemical tankers, at some point you will create a catastrophe if it goes wrong.”
