ABSTRACT

 

Undisturbed natural habitats, including protected areas cover only about 5% of the worlds land area. On the other hand nearly two-thirds of the terrestrial environment of the planet consists of managed ecosystems. A large proportion of the world’S biological diversity coexists with humans in these man made landscapes. A good example is the wet zone of Sri Lanka where man made habitats with differing physical, chemical and biological properties, such as home gardens, paddy fields and other monoculture plantations cover most of the land area even though it is designated as one of the world’S 11 biodiversity
