After Sri Lanka secured its independence, the introductions continued unabated, and the breeding of exotic aquarium fish for export became popular. The deliberate and accidental introduction of exotic fish into Sri Lanka has led to serious ecological damage, as many of these species disrupt ecosystems , reducing the diversity of endemic fish to ...
Sri Lanka lists 12 invasive alien species of animals most of which are vertebrates and least are invertebrates. [37] In developing countries, like Sri Lanka, the consequences of the invasive alien plant species (IAPS) on biodiversity (loss of 75%) [38] have not been adequately tackled.
Cultivation of cardamom at large scale in the montane forests is a major threat to the fragile forest ecosystem. [5] [6] [7] Invasive exotic plant species such as Mist Flower (Ageratina riparia) that increasingly spread into montane forest areas and montane grasslands destroy the unique native Sri Lankan flora.

Location of Sri Lanka. Environmental issues in Sri Lanka include large-scale logging of forests and degradation of mangroves, coral reefs and soil. Air pollution and water pollution are challenges for Sri Lanka since both cause negative health impacts. Overfishing and insufficient waste management, especially in rural areas, leads to ...
It has also been introduced elsewhere. The species is commercially important as a food fish and is also farmed. [4] It can be found in the aquarium trade, as well. [5] The species has been used for weed control on highly invasive aquatic plants like Salvinia molesta, as the giant gourami can be a voracious herbivore. [6] [7]
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]
By understanding the qualitative and quantitative measures of a given invasive species probability to invade a given ecosystem, researchers can hypothesize which species will impact which environments. The addition, or removal, of a species from an ecosystem can cause drastic changes to environmental factors as well as the community's food web.
