[2] The park would be part of the proposed Trinational Biodiversity Corridor, which aims to provide forest connections between conservation units in Brazil, Paraguay, and Argentina in the Upper Paraná ecoregion.

All of the land is privately owned, leading to disputes over the designation, and in 2002 the area was declared a "managed resources reserve".

The NGO Guyra Paraguay has purchased 6,500 hectares (16,000 acres) of land in the park, which it manages as a protected area.

[1] Mammals include the jaguar (Panthera onca) and the South American tapir (Tapirus terrestris).

Twelve of the species are globally threatened, including the vinaceous-breasted amazon (Amazona vinacea) and black-fronted piping guan (Pipile jacutinga).

[1] The park holds important populations of helmeted woodpecker (Celeus galeatus), russet-winged spadebill (Platyrinchus leucoryphus), cock-tailed tyrant (Alectrurus tricolor) and saffron-cowled blackbird (Xanthopsar flavus).
