The Gran Chaco Fact Sheet
The Gran Chaco biome is situated in a region west of the Paraguay River and east of the Andes, spanning an area of 1.2 million km2 across the South American continent – an area more
than twice the size of France and three times that of California. The largest dry forest in South America is found within the Gran Chaco. This is the second largest area of forest on the continent after the Amazon.
The Gran Chaco contains a range of ecosystems including savannahs, grasslands, thorny forest, and woodland. It spans several countries, with the largest proportion in Argentina (59%), followed by Paraguay (23%), Bolivia (13%) and Brazil (5%). As a result, the region is known by many names including the Dry Chaco and Chaco Plain.
