Paitoon Intarabutra said he attended a public meeting on the issue to point out that there had been no further problems so far this season.
He said rangers dispatched to survey water sources within the sanctuary found there was ample for the animals throughout the dry season.
There were also vast stretches of grassland where they can graze, which he pointed out was a preferable choice than introducing food sources close to communities.
Paitoon said he would recruit outside help to erect electrical barriers in areas prone to invasions by elephants and rangers would patrol regularly to ensure public safety.
