Laguna de Hanson, Parque Nacional Constitución de 1857. 02/02/10; Baja California; 510 ha; 32°02'N 115°54'W; This Ramsar Site comprises a freshwater lagoon and a floodplain located in the 1857 Constitución National Park. The Hanson lagoon is considered the only natural semi-permanent water body in the forested areas of the Baja California State. Consequently, the site supports important bird populations and plays a significant role in climate regulation for the Baja California Peninsula. The Ramsar Site is also designated as an Important Bird Area (IBA) as it provides shelter, rest and reproduction areas for at least 29 bird species including migratory birds such as the Gadwall (Anas streptera) and the Redhead duck (Aythya americana). The main threat to this site comes from the extensive livestock rearing activities undertaken by the communities surrounding the National Park, who use the site as a source of water and food during the summer. Conservation and wise use activities planned to protect this Ramsar Site are currently being revised in a National Park management plan. Ramsar Site n°1923. Most recent RIS information: 2010.
