All the work associated with ensuring the elephants&rsquo safety and the annual event is carried out by Anantara&rsquos own elephant charity&mdashthe Golden Triangle Asian Elephant Foundation (GTAEF). The umpire for the tournament is John Roberts, Director of Conservation for the Anantara Group. Roberts has been involved in conservation programmes in the UK, Australia, Laos and the US, and watches each elephant closely to make sure everything is fine. Halfway through the play, Roberts directs the action to shift to a covered area as there are chances of the elephants slipping on the wet grass. The white polo ball is replaced by a larger red ball, which the elephants do not seem to like very much. So Roberts stops the play. &ldquoI could see they were confused&mdashprobably because they couldn&rsquot pop the red ball. Most of them have been in entertainment shows in the past, so they are familiar with footballs, which they have to pop as part of the routine. Our indoor ball didn&rsquot react the way they expected it to when they stood on it.&rdquo Roberts gave them some time to see if they would get used to it, but, &ldquoas they didn&rsquot settle in I called the game off. If the elephants aren&rsquot happy with something, we don&rsquot continue.&rdquo Only domestically bred elephants are selected, says Roberts. Each elephant is only allowed 30 minutes of polo time per day. They get good food, vitamins and medical care during the tournament. And, at the end of the tournament, they help raise millions in donations for the care of Thailand&rsquos elephants.
