The Kabani River and its tributaries make up a rather powerful river system in the landscape of Wayanad district. Kabani is an important tributary of the Kaveri River and one of the three east-flowing rivers of Kerala. Panamaram rivulet takes its origin from the perennial lake called, `Pookode Lake`. It flows swiftly through mountain gorges and joined by other streams, tumbles down into Panamaram valley. Six kilometres further from Panamaram, this river joins with the Mananthavady rivulet, originating from the lower regions of the peak `Thondarmudi`. From this confluence onwards, the river is known as Kabani, a mighty, perennial river which after entering Karnataka state, joins with the Kaveri River. Almost the whole of Wayanad is drained by the Kabani River and its tributaries, namely, Panamaram river, Mananthavady river and Thirunelli river.
The vegetation of the district of Wayanad is typical of the Western Ghats and the plantation crops grown in the cool climate. A major portion of the district is covered by coffee. Among the trees found here are rosewood, anjili (Artocarpus), mullumurikku (Erthrina), several species of Cassia and many other non-descript varieties which have been preserved to give shade to the coffee plants. In a majority of coffee plantations, the age-old species are replaced by the silver-oak which is suited to the cold climate. It is also used for the plywood industry and thus is economical to the farmers. Eucalyptus grandis, a shorter variety of eucalyptus, whose fragrant smell suffuses the very air around it, is cultivated on a large scale in certain parts of the district. Eucalyptus oil is extracted on commercial basis from its leaves. Of the 20,864 hectares of reserve forest, the major portion is teak plantation. Arecanut palms and jack trees are also grown here. Tea is grown as an industry in large estates. The soil and climate of Wayanad are suitable for horiculture on a commercial basis. With the clearing of forests, animal life of the forests has been on the decline. Among the animals found here are bonnet monkeys, loris, mongoose, jungle cats, squirrels, jackals, hares, etc. in the limited forest areas.
