While the Nainital district where the lake is situated (in the middle Himalayan ranges up to 2,000 m (6,600 ft), a temperate zone), is rich in flora (typical temperate climate plants) and fauna, the details of the flora and fauna specific to the lake and its surroundings recorded are the following.
The trees and bushes grown in the region (lake’s basin) with their botanical and common Indian names (in parenthesis) are reported to be: a) Quercus incana Oak (Banj)}; b) Aesculus indica (Pangar or Horse chestnuts); c) Juglans regia (Akhrot or walnut), d) Populous ciliata (Hill Pipal, a sacred tree); e) Fraxinus miscrantha (Ash tree or Angu); f) Platanus orientalis (Chinar); g) Rubus lasiocarpus (Hisalu); h) Rosa moschata (Kunj or Musk rose); i) Berberis asiatica (Kilmora);j) Cupressus torulosa (Surai or Himalayan cypress); k) Rhododendron arboreum (Buruns); Cedrus deodara (Deodar); l) Salix acmophylla (Weeping Willow); and m) Pinus (Pine).[5]
The Aquatic Macrophytic vegetation recorded are the a) Potamogeton pectinatus, 2) Potamogeton crispus, 3) Polygonum glabrum, 4) Polygonum amphibium and Polygonum hydropiper (Water pepper).[5]
Several species of medicinal flora and horticulture plants have also been reported.
The fishes found in the lake are generally carps Mahseer, (the Hindi name of mahāsir, mahāser, or mahāsaulā used for a number of fishes of the group), also hill trout and the mirror carp which breed several times during one spawning season during May to September. Two species of Mahaseer fish viz., Tor tor: The red finned mahseer and the Tor putitora: The yellow finned mahseer, a food fish which grows to varying sizes from 20 to 60 Cms (7.87 to 23.62 inches) are reported. The three species of Hill Trout found in the lake are the Schizothorax sinuatus, Schizothorax richardsoni and Schizothorax plagiostornus. The imported fish bred in the lake is Mirror carp or Cyprinus carpio.[5] Gambusia affinis also called Mosquitofish have been introduced in the lake as a biocontrol measure to control Mosquito larvae.[5]
Nine species of birds and nine species of animals have been recorded in the Nainital district.
