Hat Noppharat Thara–Mu Ko Phi Phi National Park officials, joined by staff from Trang Marine Park, worked on the coral propagation programme by bringing coral from a nursing farm to be attached to the dead reef to support recovery.
Officials said they would use a drone to follow up the coral growth on a monthly basis during the first phase before monitoring it once every four months for a year, said park head Woraphot Lomlim.
Woraphot said the four-month break was necessary because the beautiful bay had suffered from scuba diving, boat anchoring and the passage of numerous boats. Up to 4,000 visitors came each day, he said.
A pier is being built at nearby Losama Bay so that Maya Bay could be closed permanently to boats and the number of visitors would be limited to 2,000 per day, he added.
