About
Geoffroea decorticans, the chañar, kumbaru, or Chilean palo verde (green wood), is a small deciduous tree, up to 8 meters (25 ft) tall that inhabits most arid forests (montes or espinales) of southern South America. The chañar is cold and drought deciduous; it loses its leaves in winter, and possibly in summer if conditions get too dry. It is native to Bolivia, Chile, Argentina, also present in Paraguay and southern Peru. It is a very characteristic tree in local culture and folk because of its vivid visual presence, propagation, and ancient ethnomedical uses.
Where it grows
The tree inhabits dry to arid spiniferous forests in a rather broad area of southern South America which extends mainly through I to IV regions of Chile and central and northern Argentina and throughout highland Bolivia, though it is also found in Paraguay, Peru and Uruguay. Its companions conforming the forest are usually algarrobos, quebrachos, and the related and very abundant cavens. The species is in some areas associated with woody plant encroachment.
