One of the many reasons as to why people visit Sri Lanka is because of its very diverse wildlife. From flora to fauna, a lot of species are only endemic to Sri Lanka. A lot of people, even the locals come to nature reserves and forests to get a glimpse of rare creatures for maybe once in their whole lifetime. Allot of nature reserves and sanctuaries are in Sri Lanka in order to protect the wildlife from human interests that might harm the animals including poaching. Visitors are allowed in to these reserves where you can take safari trips with a trained guide provided by the reserves themselves.
