Critical Situation Analysis (CSA) of Invasive Alien Species (IAS) Status and Management, Saint Lucia, 2010
This Critical Situation Analysis (CSA) provides an overview of occurrence, trends in distribution of most problematic Invasive Alien Species (IAS), in Saint Lucia, including an assessment of pathways and on-going management approaches. It assesses gaps in existing institutional, legislative and policy frameworks, building on earlier studies, and should be read together with several cited reports prepared in parallel as inputs into the National Invasive Species Strategy (NISS). Early sections describe Saint Lucia’s environmental profile, including protected areas, marine reserves, and other sites of high conservation value. Both biodiversity baselines assessments and IAS inventories are discussed regarding their merits and limitations. Generally terrestrial ecosystems are better understood than aquatic ones, where baseline studies are scarce, poorly documented where they exist, and the origin of species is often unknown.
