Abstract

The Sinharaja forest reserve is one of the least disturbed and biologically unique tropical lowland rain forests in Sri Lanka with the eastern Sinharaja consisting of moist sub-montane forests providing habitat par excellence for amphibians. However, the diversity of amphibians in the eastern and southern sections of Sinharaja is inadequately researched. Hence, this research focuses on studying amphibian diversity in lowland rain forests and sub-montane forests in eastern and southern Sinharaja. This research is guided by Quantitative Deductive research methodology and 16 line transects and 16 quadrate samples are used for primary data collecting. Twenty-four amphibian species were identified, 22 (92%) species of which are endemic to Sri Lanka. The amphibian species identified included 5 vulnerable species, 7 endangered species and 8 critically endangered species. The highest number of species, including endangered and critically endangered species were recorded in the sub-montane forests than in lowland rain forest. Major threats to the existence of amphibian species were issues related to biopiracy including loss of forest genetic resources and wildlife smuggling, illegal forest utilization practices, gem mining, illegal forest encroachments and unethical tourism practices. Thus, the Forest Department and other responsible authorities must attend to minimize the effects of these negative human impacts on these vulnerable areas in order to protect and conserve the diversity of sensitive amphibian species in their habitats.
