Invasive species

Invasive Alien Species are recognized as a major driver of biodiversity loss across the world, not only affecting nature but also economy, food security and human health.

Invasive species are a major threat to freshwater biodiversity across the Mediterranean basin, often leading to important social and economic impacts where they occur. These threats are unequally distributed over the Mediterranean region, with some areas being more impacted than others. For example, the biodiversity of lakes of the eastern part of the region has been particularly vulnerable after the introduction of non-native invasive fishes, which led to three species becoming extinct (Alburnus akili, Aphanius splendens, Pseudophoxinus handlirschi) (Freyhof et al. 2014).

Invasive alien species have therefore been prioritised as a key issue to discuss in international policy fora, including Objective 2 of the Mediterranean Strategy for Sustainable Development 2016-2025 and Target 15.8 of the Sustainable Development Goals (SDGs). Both call for the prioritisation of invasive alien species for prevention, eradication or control to halt loss of biodiversity.
