Wildlife Oddly lowland endemic birds such as Ceylon Rufous Babbler are missing, although other scarce endemic species such as the Serendib Scops Owl are present. Mammals likely to be seen are Grizzled Indian and Layard's Striped Squirrel. The southern race of the endemic Purple-faced Leaf Monkey can also be seen. Endemic lizards seen include the Rough-nosed Horned and Hump-nosed Lizard. Butterflies include Tree Nymphs and Commanders. The Gal Karandha (Humboldtia laurifolia) is common. It has hollow stems in which ants live, an example of a symbiotic relationship.
