Portugal’s Institute for the Conservation of Nature and Forests (ICNF) has launched a campaign to raise awareness about responsible dolphin observation in the Sado Estuary. The initiative specifically targets recreational boaters, emphasizing the importance of adhering to regulations designed to protect the local dolphin population. These rules are crucial for ensuring the well-being of these marine mammals and maintaining a sustainable coexistence. The campaign aims to minimize disturbance from nautical activities, safeguarding dolphins from potential harm. By promoting respectful practices, the ICNF hopes to balance recreational use of the estuary with the conservation of its valuable biodiversity. The effort underlines Portugal’s commitment to protecting its marine life and preserving the Sado Estuary as a vital habitat. The ICNF stresses compliance with existing guidelines for a harmonious environment.
