Mai Khao beach is among the few beaches in Phuket that act as nesting grounds for sea turtles. Thus, the Minor Hotel Group, as part of its conservation projects, set up the Mai Khao Marine Turtle Foundation that engages in protecting and conserving endangered sea turtles in Phuket and other areas in Thailand. The foundation was founded with a donation of 45,000 US dollars donated by the JW Marriott Phuket Resort and Spa and the Minor Hotel Group. Through the Mai Khao Marine Turtle Foundation turtle eggs are collected from areas where they are threatened. There onwards they are handed over to the Phuket Marine Biological Centre and the Royal Thai Navy who provides a sanctuary for the eggs until they hatch and ensure the young turtles reach the sea safely.
