There are three main types of forest in the sanctuary: tropical moist deciduous occur in the western Benne Block, where rainfall is higher than in the other blocks.
Tropical dry deciduous forest occurs in the middle and southern tropical dry thorn forests are in the east.

In addition there are patches of tropical evergreen forest in the southwest and western part of Mudumalai.
The annual rainfall there exceeds 2,000 mm (79 in).
Tree species in this habitat include Casseria ovoides, Litsea mysorensis, Cinnamomum malabatrum and Olea dioca.
Climbers including sneeze wort (Dregea volubilis), Gnetum ula and Entada scandens are also found in these semi-evergreen forests.

Moist bamboo brakes are found amidst dry deciduous, moist deciduous and semi-evergreen forests and along the fringes of riparian forests and swamps.
There are two species of bamboo found in Mudumalai, the giant clumping bamboos: Bambusa (arundinacea) and Dendrocalamus strictus.
Elephants and gaur eat both species of bamboo.
In all types of forest, a green strip of riparian forest is seen along the shore of dry seasonal and perennial streams.
This type of forest remains green in all seasons.
The plant species found here includes: Mangifera indica, Pongamia glabra, Terminalia arjuna, Syzygium cumini, Indian rosewood Dalbergia latifolia and the bamboos.
Larger mammals such as elephant, gaur, sambar and tiger use riparian forest patches for feeding and resting.

This sanctuary is home to several species of wild relatives of cultivated plants including wild rice, wild ginger, turmeric, cinnamon, solanum, guava, mango and pepper that act as a reserve gene pool for the cultivated plants.
In places mixed vegetation types are present.
The deciduous trees shed their green leaves during the summer, and adopt a floral garb while the arrival of the monsoons hails fruits and tender greens.
