It is also the primary threat to the survival of Sri Lanka's biodiversity. [2] Sri Lanka has 751 known species of amphibians, birds, mammals and reptiles of which 21.7% are endemic, and over 3314 species of vascular plants, of which 26.9% are endemic. [4]
Whereas invasive alien species (IAS) are second to habitat degradation, for human actions have the first and direct effect on that, they (IAS) are still recognized as a major threat to Sri Lanka's native biodiversity. [36] Sri Lanka lists 12 invasive alien species of animals most of which are vertebrates and least are invertebrates. [37] In ...
Biodiversity loss happens when plant or animal species disappear completely from Earth or when there is a decrease or disappearance of species in a specific area. Biodiversity loss means that there is a reduction in biological diversity in a given area. The decrease can be temporary or permanent.
When economic costs of invasions are calculated as production loss and management costs, they are low because they do not consider environmental damage; if monetary values were assigned to the extinction of species, loss in biodiversity, and loss of ecosystem services, costs from impacts of invasive species would drastically increase.

These results influence the aesthetic of the landscape, decrease the biodiversity, cause health problems and have negative impacts on Sri Lanka's tourist industry. The study shows that in areas without waste collection, the majority of people dump their waste that should be going to the landfill in their backyard.
Of 3,210 flowering plants belonging to 1,052 genera, 916 species and 18 genera are endemic. [3] All but one of Sri Lanka's more than 55 dipterocarp (Sinhalese "Hora") are found nowhere else in the world. Sri Lanka's amphibian diversity is only becoming known now. Sri Lanka may be home to as many as 140 species of amphibians.

Climate change is likely to favour some invasive species and harm others, [3] but few authors have identified specific consequences of climate change for invasive species. [4] As early as 1993, a climate/invasive species interaction was speculated for the alien tree species Maesopsis eminii that spread in the East Usambara mountain forests ...
