It belongs to the Ramsar Site Chaco Wetlands and plays a fundamental role in conserving this unique ecosystem.

establishment of Laguna El Palmar National Park was a significant milestone in environmental protection in Argentina. With this designation, approximately 708,000 hectares were added to the country’s system of protected areas. This action aligns with international agreements for biodiversity conservation, such as the agreement signed at COP 15, which aims to protect at least 30% of the world’s lands and waters by 2030.

The park harbors a wide variety of flora and fauna and is recognized as an Important Bird and Biodiversity Area (IBA) according to the press release, due to its rich birdlife. More than 200 species of birds have been recorded in the area, including the crowned eagle, osprey, white-winged nightjar, jabiru stork, various species of ducks, and many others.

In addition to its ecological significance, the park also holds a rich cultural history. Archaeological remains indicating the presence of pre-Columbian cultures, such as the Guarani, have been found. European influence can also be observed in the architecture and local traditions.

Biodiversity: Ecosystem, Fauna, and Flora


Laguna El Palmar protects a significant portion of the Delta and Islands of Paraná ecoregion. This park contributes new conservation values to the system of protected areas due to its location in the Subregion Lower Paraguay Complex and its relationship with the Chaco Humedo ecoregion.
The park features a wide diversity of environments, including lagoons, wetlands, ravines, grasslands, gallery forests, white palm or caranday palm groves, river alder and criollo willow forests, and hardwood or monte fuerte forests.

These diverse habitats provide shelter and sustenance to a wide variety of plant and animal species. The presence of lagoons and wetlands creates a suitable environment for aquatic life, including fish, amphibians, and reptiles. Grasslands and forests host a diverse range of birds, mammals, and other organisms.

The white palm or caranday palm groves are particularly prominent in this ecosystem. These palms are endemic to the region and play a vital role in ecological balance. Additionally, the river alder, criollo willow, and hardwood forests are important for biodiversity conservation and soil protection.

Ecosystems and Biodiversity


The park is renowned for its Yatay palm forest, an endangered species that grows in the region, also present in El Palmar National Park. It is also home to numerous species of native shrubs, herbs, and trees. It exhibits an environmental mosaic characteristic of the Chaco wetlands. Different environments can be distinguished based on variations in the soil.

In the sedimentary hills known as "albardones," riverine forests or gallery forests are found. Species like black laurel, white timbó, ingá, and blood of the dragon grow here, along with vines and shrubs, with the ñandipá or genipa standing out.

In the lower areas, lagoons of varying depths form, ancient paleochannels of the Paraguay River. These lagoons harbor floating species like water hyacinth, water lentils, and water lilies.

The "estero," another distinctive habitat in the park, is characterized by its shallow depth and the presence of decomposing organic matter. Species like pirí, paja techadora, huajó, totora, and pacourina can be found here, with the latter being a unique marsh species in this park.

In elevated areas, grasslands dominated by yellow grass, espartillo, and foxtail, along with thorny shrubs like aromito, are found. The white palm or caranday palm groves also extend in this area.

Lastly, on the white and saline hills, hardwood or monte fuerte forests develop. Species like urunday, black carob, lapacho, and guayaibí are found here, accompanied by shrubs, terrestrial bromeliads, vines, and epiphytes.

In summary, the flora of Laguna El Palmar National Park presents a wide variety of environments and species adapted to the conditions of the Chaco wetlands. From riverine forests to palm groves and hardwood forests, this ecosystem hosts a rich plant diversity.
