The official said in the second wave of floods in Assam, 80 per cent of the park's 481 sq km area was inundated.
Since August 10, seven rhinos, 122 swamp deer, two elephants, three wild boars, two hog deer, three sambhar deer, one buffalo and one porcupine died, KNP Divisional Forest Officer (DFO) Rohini Ballav Saikia said here, adding, "Carcasses are being recovered daily."
Out of the seven dead rhinos, six drowned while the other died of natural causes. Water of the Brahmaputra river entered the KNP, a UNESCO World Heritage Site, through river Difloo since August 10 the DFO said.
Asserting that loss of infrastructure and property will be another burden on KNP authority, he said preliminary work for temporary renovation would be started as soon as roads become operable.
At present, animals in KNP are moving in search of food available on both sides of NH-37 and the adjacent tea gardens towards the higher altitudes of Karbi Anglong district, the official said.
