National Parks in the Paraguayan Chaco

There are a number of national parks and protected areas in the Paraguayan Chaco. The Paraguayan Chaco is the part of the Gran Chaco, South America's second-largest forest, which is within Paraguay, making up 23% of its ~1.000.000 km² land area. It is the largest bioregion in Paraguay, and can be divided into the northwest Dry Chaco, covered by xenomorphic forests adapted to irregular rainfall, and the Humid Chaco, a mosaic of dry forests, palm savannahs, and seasonally flooded wetlands.

Geologically, the Great South American Chaco is a plain and its formation, millions of years ago, is very closely related to the formation of the Andes and the erosive process afterwards. Originally the Chaco was a basin, which within time, was filled with sediments of aerial origin (through wind action) and of pluvial origin (through rivers taking and depositing sediments in the Chaco).

The Paraguayan Chaco is threatened by deforestation, wildfires, and poaching. 50% of the forest covered is projected to be lost as a result of cattle ranching and soy production by 2030, according to the World Land Trust.
