Corbett National Park is rich in vegetation, with different kinds of trees and shrubs. Consisting of tall and slender sal (Shorea robusta) trees. Shisham (Dalbergia sissoo) and khair (Acacia katechu) trees are found in the middle reaches, bakli (Anogeissus latifolia), chir (Pinus roxburghii), gurail (Bauhinia racemosa) and bamboo trees. There are 110 species of trees, 51 species of shrubs, and over 33 species of bamboo and grass that are mostly found in chowds, or meadows.

Corbett National Park has more than 50 species of mammals, 585 species of birds and 25 species of reptiles, but the Park is known for its elephants and leopards, not its tigers. Many kinds of deer, namely chital (spotted deer), sambar (Indian stag), chinkara (Indian gazelle), pada (hog deer) and muntjac (barking deer) abound in the Park. Tiger sighting is rare, in spite of a lot of alarm calls from monkeys and deer.

Elephant herds comprising tuskers, females and calves are commonly seen. However, an elephant herd with calves is perhaps the most dangerous encounter in the wild, for elephants are very possessive of their young and do not hesitate to charge at intruding human beings.
