Floristic Regions of Sri Lanka
Other than these major floristic regions of Sri Lanka traditional home garden systems and man-made lakes (Wewa) play an important role by providing fitting ecosystems for fauna and flora of Sri Lanka. These man-made ecosystems are highly productive and managed continuously for the purpose of domestic consumption of food items and for other economic needs. Traditional home garden systems are found throughout the country and they are varying in the composition of plants and animals as well, due to the locality in the country. However Traditional home garden systems are home to various kind of EASL, mainly, for Dragonflies, Butterflies, Bees, Land Snails, Amphibians, Reptiles and Birds.

Wewa is a traditional symbol of Sri Lankan villages, especially in Dry Zone. There are over 10,000 man made lakes in Sri Lanka, which were built by ancient Sri Lankan Rulers to collect water from the rain in the rainy season and used in agricultural practices and even for inland fisheries. Still the cascade systems or man-made wewa play an important roll to enrich the biodiversity and which were created realistically in sustainable manner used by a large community. The cascade system has aquired a semi-natural environment with its evolution. However sometimes these cascade systems are comparatively rich in biotic and abiotic interelations than remaining ecosystems in Sri Lankan Dry Zone. At finally, yet more imortantly cascade systmes are most advance-ever known-sustainable ecosystems with dynamic livelihood practices, enduring for several millennia.
