Southern Dry Mixed Deciduous Forests 5A/C3
This type of forest is attributed to relatively low rainfall. Many species found in this forest type are common to the moist deciduous forests also. However their percentage of occurrence is less. The leaf fall starts earlier as compared to moist deciduous forests. Generally the trees remain leafless between January and May. The dominant trees attain good height and are not gregarious. The canopy is comparatively open. Grasses and herbs are more. Bamboos occur as under growth which are heavily browsed and become bushy. New culms of Bamboos grow during November - December. These forests are highly prone to fire. By December – January, the grass and many herbs dry up and leaf fall starts too. The forest floor is thickly covered with dry twigs and leaves. Biotic interference is also more due to many human habitations in and around the sanctuary. Therefore forest fires are common in the dry deciduous forests. It is degraded and thus a few fire-hardy species are common in these areas.
