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 a degree that causes extinction. Invasive introduced exotic fish, such as the Sail-fin pleco, also cause economic damage by reducing the amount of ...

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. [8] [9] [10]
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]
The introduced species risks being invasive. Invasives displace local species, resulting in a reduction of biodiversity, a condition also to be expected if great extensions are forested using introduced species. McEvoy [7] is very clear and strict: introduced species can not be used at all when working in a close to nature forestry system.
Sri Lanka map of climate classification zones. Sri Lanka is in the north-equatorial tropical zone. Therefore it experiences a climate with high rainfall and temperature which permits the county to be broadly classified into groups as follows. Terrestrial ecosystems Forests – Lowland rain forests, dry monsoon forests, montane forests, thorn scrubs
Sri Lanka is a small island nation with rich and various marine ecosystems. Thus, the inhabitants of Sri Lanka rely heavily on fisheries, with approximately a quarter of a million families make their living from fishing. [34] However, climate change in Sri Lanka can impact biodiversity offshore.
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 ...
