It was the first municipal nature reserve established in Argentina, founded in 1982.
The park preserves the last remnants of the coastal forest that once lined the Rio de la Plata in the Buenos Aires province.
The area functions as a biological corridor for migratory birds traveling through the Atlantic flyway.
The park's soil composition includes silt and clay deposits left by the Rio de la Plata, which are highly fertile for native species.
It is home to the nutria (coypu), a semi-aquatic rodent frequently sighted in the park's internal lagoons.
Municipal Ribera Norte Natural Park is a 10-hectare protected area located on the banks of the Rio de la Plata in Acassuso. It serves as the first municipal nature reserve in Argentina, dedicated to the conservation of the original coastal ecosystem. The terrain consists of floodplains and riparian forests that provide a habitat for over 200 species of birds. Visitors access the preserve via elevated wooden walkways designed to minimize human impact on the soil and vegetation. The park functions as a center for environmental education, focusing on the native flora of the Espinal and Delta ecoregions. It is managed by the San Isidro Municipality in collaboration with the Fundacion Natura. Native vegetation, including ceibo and sarandi trees, dominates the landscape. The park is susceptible to tidal flooding, which periodically alters trail accessibility.
