When I was there and visited much of the Park in 1994 most of the forest in the centre and Western side of the Park had already been decimated by elephants with all trees lopped off by elephant at a certain height. If the population of elephants continued and increased over the next twenty years, the damage must truly be horrendous. "Conservationalists" I spoke to back then refused to recognise it as a problem ... guess there was no money in their pockets from elephants being a problem ...
