The flora of Wayanad are characteristic of the Western Ghats and the plantation crops grown in the cool climate. A major portion of the district is covered by coffee. Trees of the wild type like rose-wood, anjili (Artocarpus), mullumurikku (Erthrina), several species of caussia and many other non-descrip varieties are still preserved here and there, to give shade to the coffee plants. These trees give a dembalance of wilderness to the landscape of Wayanad. In a majority of coffee plantations, the age-old species are replaced by the silver-oak which is suited to the cold climate. This tree grows quickly and its cultivation is widespread among coffee plantations for shade and for giving support to pepper. It is 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 centain 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 commercial basis. For promoting the cultivation of vegetables and raising of orchards, the Kerala Agricultural University is running a Regional Agricultural Research Station at Ambalavayal. With the clearing of forests, the diverse and buzzling animal life, characteristic of the forests of Western Ghats, has vanished from Wayanad. One can still see the bonnet monkeys, loris, mongooses, jungle cats, squirrels, jackals, hares, etc. in the limited forest areas. Elephant, bear and other wild animals from the neighbouring wild life sanctuaries of Karnadaka and Tamil Nadu, stray into the Begur forest range and the forests around Muthanga, which is 20 kilometres away from the town of Sulthan Bathery.
