The farm is home to many species of animals, birds, reptiles and insects.

30-40 peacocks inhabit the farm and a many can be seen while taking an evening walk through the farm. Malabar Pied Hornbills, Brahmini Kites, Serpent Eagles, Kingfishers, Woodpeckers, Barbets and Parrots are some of the other resident bird species frequently seen on the farm.

One boundary of the farm is the recently established Kalawewa National Park. Many species of wildlife including large herds of elephants are to be found in the area. Ellawala Horticulture is sensitive to the wildlife in this habitat and strives to maintain agricultural practices that have the least impact on them.

The electric fence maintained by the farm prevents elephant intrusions and also helps protect the boundary of the National Park from unauthorized entry. The electric fence has also helped the Dambewatana village by reducing the incidence of elephants entering inhabited areas.

Many butterflies, dragonflies and other insects too can be seen on the farm. This is a testament to the frugal and careful use of pesticides and insecticides by the farm management. The use of herbicides on the farm was discontinued around 2010 and all weed control practices are now either mechanical or manual.
