Bamboo

In some parts of Corbett the vegetation is dominated by bamboo forest. The main species is Male Bamboo having clustered stout stems and shining papery stem sheaths. Bamboos follow a peculiar flowering process. All bamboos in a forest, flower together at the same time once in several decades. After flowering, fruiting and dispersal of seeds, all plants die together. 

Shrubs  

Shrubs dominate the forest floor. There are several species of Ber found in open areas that provide food and habitat to many birds and animals. Maror phali is an easily noticeable shrub. Its fruits are in the form of twisted spiralling pods. Karaunda with pinkish-white flowers and sour fruit is found under sal. Hisar has yellow, juicy, berry-like fruits that are savoured by animals.
