Crocodiles basked on the rocks by the dozens. Otters lived on the burrows along the bank. The trees along the banks on either side of mangoes, teak, punnai and occasional rosewood, reach a massive size. The island has, in addition to these trees, various species of terminalia and clumps of bamboo. The highlight of any tourists stay at Nisargadama can be the three-kilometer walk around the island, along the river.
Dewdrops hang like fresh pearls, glistening in the morning sun, on the webs of wolf spiders.
Many varieties of butterflies can be seen flitting around. A pied Maratha woodpecker can put up an appearance, followed by a Rufous woodpecker. Flocks of blossom-headed parakeets flit from treetop to treetop, calling to each other constantly. Lorikeets join in the cacophony. Crimson-colored scarlet minivets and nuthatches can be spotted too.
