These biological invasions - mainly driven by intensified global trade and human mobility - also have consequences for public health, local livelihoods and economic activities.To address these challenges, the PRIBES project (\"Estratégia regional para o controlo e prevenção de espécies exóticas invasoras\"; LIFE IP AZORES NATURA - LIFE17 IPE/PT/000010) advocates the implementation of an integrated regional strategy for the management of terrestrial and freshwater invasive species. The proposed framework focuses on coordinated governance through a dedicated task force, strengthened preventative actions including biosecurity measures and risk analyses and early detection systems supported by monitoring programmes and citizen-science initiatives. It also promotes a hierarchical management approach, ranging from eradication to long-term control and mitigation, according to feasibility and economic sustainability.This strategy is supported by scientific research aimed at understanding invasion pathways and evaluating management outcomes, as well as collaborations at national and international levels that encourage data exchange and shared expertise. Public engagement is fostered through awareness campaigns and educational activities. In parallel, the Azores Bioportal functions as a key open-access repository for biodiversity information, providing validated species records and connections with international biodiversity networks. Together, these initiatives contribute to monitoring both native and invasive species, while offering valuable resources for conservation planning and evidence-based decision-making.In the scope of the PRIBES Project and the Azores Bioportal, we started a series of data papers with new spatial records of vascular plants gathered during field campaigns across several Azorean Islands between 2019 and 2025.
