The Gran Pajonal (Great Scrubland or Great Savanna) is an isolated interfluvial plateau in the Amazon Basin of Peru. It is located in the departments of Ucayali, Pasco and Junín. The plateau is inhabited by the Asháninka or Ashéninka people along with late-twentieth century immigrants largely from the Andes mountains of Peru. In the 1730s, Roman Catholic Franciscan missionaries established missions in the Gran Pajonal, but the missions were destroyed in the 1740s by the Ashaninka under the leadership of Juan Santos Atahualpa.

Beginning again in 1897, missionaries, collectors of rubber, settlers, and the government of Peru began to encroach on the Gran Pajonal. In the 1980s, the Asháninka achieved a measure of security when most of the land of the Gran Pajonal was deeded to 36 communities. The population of the Gran Pajonal in 2002 was estimated at 7,000, of which 90 percent were Asháninka.

The plateau area of the Gran Pajonal as defined by different scholars is between 2,000 square kilometres (770 sq mi) to 4,000 square kilometres (1,500 sq mi). The term Gran Pajonal is often applied loosely to a much larger area. The Gran Pajonal has elevations ranging from about 900 metres (3,000 ft) to 1,400 metres (4,600 ft) and is incised by the headwaters of several small rivers.[1]

The Gran Pajonal was named by the Spanish because, in a region of tropical rain forest, it features patches of small grasslands amounting to about 4 percent of its total area. The Pajonal has no definite boundaries, but lies east of the Cerro de la Sal (Salt Mountain) area and is an outlier of the Andes. It rises above the Palcazu River on the west and the Ucayali River on the east and is bordered on the south by the Perene and Tambo rivers. The El Sira Communal Reserve and mountains border the Pajonal on the north. The Cerro de la Sal mountain range outlines its southern boundary. Mountains around the edge of the plateau have elevations of more than 1,800 metres (5,900 ft).[2][3]

The elevation of the Gran Pajonal results in lower average temperatures than the Amazon lowlands. Average temperatures on the plateau range from 21 °C (70 °F) to 23 °C (73 °F). Annual precipitation is more than 2,100 millimetres (83 in) with a three-month dry period (June to August). The natural vegetation is tropical rain forest except for the anthropogenic grasslands, totaling about 9,700 hectares (24,000 acres) and deriving from hundreds or thousands of years of cultivation by the indigenous people. In 2004 another 3,500 hectares (8,600 acres) of grasslands used as pasture had been created since 1975 by immigrants to the area, mostly farmers from the Andes.[4]
