The government has formed four teams to assess the damages to the Sundarbans caused by Cyclone Yaas, which formed in the Bay of Bengal and hit the coastal areas of the country Wednesday.

Assistant conservators of forest (ACFs) of the Sundarbans East and West zones were tasked with the responsibility.

Md Moyeen Uddin Khan, the forest conservator of the Khulna region, formed the teams.

Most parts of the Sundarbans have become inundated following a downpour induced Yaas, causing serious harm to wildlife. 

The Sundarbans was the first area in Bangladesh to take the hit of the strong wind and tidal surge caused by Yaas.

The mangrove forest was flooded by a 5-7-foot tidal surge which damaged vessels and forest resources.

At least four deer drowned during the heavy tidal surge and two were rescued alive as they were getting washed away, Moyeen Uddin said.

Mohammad Joynal Abedin, ACF of Sharankhola range under Sundarbans East zone, said: "We are taking stock of the damage caused by recent flooding. However, the strong tides in the rivers crisscrossing the Sundarbans are disrupting our work. Since most of the area is underwater now, it is difficult to ascertain actual damage."
