As Minsontaung Wildlife Sanctuary is located in the rain shadow of the Arakan Mountains, it harbours dry forest dominated by Acacia catechu, Acacia leucophloea, Acacia arabica, Tectona hamiltoniana and Terminalia oliveri. Grasses such as Diectomis fastigata and Apluda mutica grow in open areas. The sanctuary provides habitat to the Burmese star tortoise (Geochelone platynota), which is endemic to Myanmar's dry zone.
