Réserve écologique de Vicente López, Nature reserve in La Lucila, Argentina.

The Reserva ecológica de Vicente López is a nature reserve along the Río de la Plata coast in the Buenos Aires metropolitan area, made up of marshes, forests, and grasslands arranged in separate natural zones. Each of these habitats supports its own plant and animal communities, all within a single protected area.

The municipal government created this protected area in 1983 to keep the local ecosystem from being built over or degraded. It was one of the early efforts to safeguard the remaining natural land along the riverbank in this part of the Buenos Aires suburbs.

The reserve's plant nursery supplies seedlings for its own replanting work: 70 of the 247 native vascular plant species recorded here were reintroduced through plantings. Each tree, shrub, vine or grass is set in its specific habitat, recreating the ecosystems once found in Vicente López. The visitor centre holds a small museum of taxidermied local species.

The reserve is open every day of the year, though opening hours change with the season. Rangers are available on site and can help with orientation or answer questions during your visit.

The reserve's artificial lagoon is linked to the Río de la Plata by a tunnel, so river water flows in and out with the level of the estuary. The surrounding embankment of rubble was raised to 8 metres above the river's mean level, higher than any flood on record.
