Flora and Fauna in Jim Corbett
The different habitat types of Corbett i.e. mountains, sal forests, chaurs, khair-sissoo forests, and rivers have their distinct assemblage of plants. More than 600 species of trees, shrubs, herbs, bamboos, grasses, climbers and ferns have been identified in the Park.
The most visible trees found in Corbett are sal, khair and sissoo (see Habitats and Ecosystems). Many other species that contribute to the diversity, are found scattered throughout the park.
Chir pine (Pinus roxburghi)
is the only conifer of the Park and is found on ridge-tops like Chir Choti but comes quite low in Gajar Sot. The upper reaches near Kanda have Banj Oak (Quercus leucotrichophora) growing which is essentially a Himalayan species.
include Khajur or Date-palm (Phoenix sp.) that occurs in open areas. Wallachia densiflora is a rare palm characteristic of Eastern Himalayas but is found in Corbett near Sultan. Kanju (Holoptelia integrifolia), Jamun (Syzygium cumini) and Aamla (Emblica officinalis) are found scattered throughout the lower areas while Tendu (Diospyros tomentosa) occurs in moist areas. Other major tree species are Bel (Aegle marmalos), Kusum (Schleichera oleosa), Mahua (Madhuca indica) and Bakli (Anogeissus latifolia).
lend colour to the forests in Corbett. The main ones are Kachnaar (Bauhinia variegata) with pink to white flowers, Semal (Bombax ceiba) with big red blooms, Dhak or Flame-of-the-forest (Butea monosperma) with bright orange flowers, Madaar or Indian Coral (Erythrinia indica) with scarlet red flowers and Amaltas (Cassia fistula) with bright yellow chandelier like blooms. Some species of trees that do not occur naturally in the Park have been artificially planted in and around habitation. These include Teak (Tectona grandis), Eucalyptus, Jacaranda (Jacaranda mimosaefolia), Silver Oak (Gravillea robusta) and Bottlebrush (Callistemon viminalis), and can be seen in and around forest rest houses.
Herbs include many species of wildflowers belonging mostly to Pea and Aster families. They are most visible on grasslands or chaurs and on open areas. Drymaria diandra is a spreading annual herb with heart shaped leaves and occurs in moist shady places. Bhilmora (Rumex hastatus) is a sour tasting herb used for making chutney. Other species encountered in Corbett are Euphorbia hirta, a hairy herb, Indigofera liniofolia with bright red flowers, Clover (Oxalis sp.) with three leaflets, Solanum sp. and Leonotis nepatafolia (orange flowers and spiky round fruits).

They include Kansi (Saccharum sp.), Themeda arundinacea, Baib or Bhabar (Eulaliopsis binata), Narkul (Arundo donax), Tiger Grass (Thysanolaena maxima), Khus Khus (Vetiveria zizanioides), Cymbopogon flexuosus (a tufted grass with pleasant aromatic leaves), Aristida cyanantha (found amidst boulders), Neyraudia arundinacea (with light brown inflorescence) and Heteropagon contortus (Spear Grass with conspicuous sharp blades that adhere to clothes and penetrates skin).
