Located in the Tagus Estuary Natural Reserve, EVOA’s primary mission is the conservation of the estuary and Lezíria avifauna, alongside the protection of the natural and agricultural habitats on which these species depend. Our vision is to create a space where natural wealth is both valued and shared, offering visitors a unique experience while fostering a lasting connection with nature. We aim to ensure the preservation of bird diversity, facilitate scientific research, and raise awareness of the importance of sustainable water and land management.
