Introduction: The Red List is one of the best indicators of the health of a species as it is an assessment that takes into consideration most of the internal and external factors that influence the long-term survival of the species being assessed. It is a very useful tool that provides the basis for…

Biodiversity is an asset of tremendous value both locally and globally. It is essential that this precious diversity of flora and fauna are preserved for future generations. The National Red List 2020 – Conservation Status of the Flora of Sri Lanka, calls upon our urgent attention to protect native…

Alien invasive species are considered a serious threat to biodiversity, and all nations are gearing towards minimizing their impacts. Early detection and rapid response are identified as one of the most effective methods for minimizing their detrimental impacts. The present study reports the…
