The San Pedro de Quilcay wetland is located on San Pedro de Lurín beach, Lima, Peru and does not have any conservation category to date. The change in land use in the lower basin of the Lurín River, the non-inclusion within a category of conservation, and the contamination and closure of irrigation canals that fed the wetland have drastically affected this ecosystem. In this work, physical and biological characterization of this wetland was carried out between 2016 and 2020; in addition, its ecosystem services were identified and the environmental history of this ecosystem based on secondary sources is briefly described. The physical characteristics of the wetland were determined. For the evaluation of birds, the point count protocol was used and for the evaluation of reptiles, opportunistic records were used. For the qualitative record of flora, the search for species was carried out throughout the wetland. Ecosystem services (ES) were identified according to the Millennium Ecosystem Assessment. Until 2018, it was estimated that the wetland had an area of ​​4.4 ha and a depth between 15 and 54 cm, with a superficial and temporary water regime. Among the fauna, a total of 65 species of birds belonging to 13 Orders and 28 Families were recorded. According to their seasonality, 36 are residents, 18 migratory-continental, five Migratory-Andean, four accidental records, one migrant from the south and one local migrant. Two species of reptiles were also recorded. The vegetation is composed of 23 species characteristic of coastal wetlands. The wetland provides supporting, provisioning, regulating and cultural ES. The recent environmental history of this wetland from 2016 to 2020 indicates that this ecosystem has been an important habitat for local and migratory birds, and mainly provides ES of biodiversity and cultural reserves. As of the closure of the irrigation canals in the middle of 2019, the ecosystem and the ES it provided were being lost.
