The Llanos de Moxos was the setting for
pre-Columbian agriculture, and appears to have been an early center of plant domestication. The inhabitants constructed agricultural
earthworks: raised fields, causeways, canals, and about 4700 forested
mounds over a 50,000 square kilometer area. Construction lasted from about 8850 BCE to about 1450 CE. Cultivation included
manioc from about 8350 BCE,
squash from about 8250 BCE, and
maize from about 4,850 BCE. Several domestic crops, including manioc, squash,
peanut, some varieties of
chili and some
beans, are genetically very close to wild species living in the Llanos de Moxos, suggesting that they were domesticated there. The people made decorated
pottery, wove cotton cloth, and in some places buried their dead in large urns. Although Europeans arrived in
South America in the late 15th century, they did not come to settle in the Llanos de Moxos until the late 17th century. The missions established by
Jesuit missionaries in the 17th and 18th centuries became many of the modern towns in the region. Since the 1950s, ranching has become the most important industry, and ranches dominate the landscape. ==Jesuit Missions of Moxos==
