Eugenia haeckeliana was long considered extinct until its rediscovery in 2024, 142 years after its first and only recorded collection. In the National Red Lists of 2012 and 2020, the species was classified as Critically Endangered (Possibly Extinct). Its habitat occurs within a highly urbanized coastal city and is surrounded by a man-made landscape. Located on privately owned land, the species and its habitat lack legal protection, rendering the site highly vulnerable and unsuitable for long-term persistence. Notably, the population narrowly survived the 2004 tsunami that devastated Sri Lanka’s southern coastal belt.

Developing effective species recovery and management plans remains challenging for many taxa due to limited baseline information on taxonomy, ecology, distribution, population dynamics, reproductive biology, and threat status. Such knowledge gaps hinder the implementation of holistic conservation strategies, which are essential for safeguarding narrowly distributed, threatened, and isolated populations.

This study adopts an integrative conservation framework to ensure the long-term survival of E. haeckeliana. Through a multi-faceted approach, it aims to address critical information gaps and enable evidence-based conservation actions. Furthermore, the study seeks to provide scientifically sound guidelines applicable to the conservation of other endangered, isolated endemic species, in line with established principles of conservation biology.
