This year's Invasive Species Awareness Week, which runs from February 20 to 26, aims to raise awareness of the impact that invasive alien species have on biodiversity and the urgency of taking action to address this issue. The Convention on Biological Diversity defines invasive alien species (IAS) as species that threaten biological diversity through their introduction and/or spread outside of their natural habitat. Invasive species can harm their non-native ecosystems, threatening native species and overall biodiversity.
