The Chilean matorral constitutes a 100 km-wide strip extending along the central part of the Chilean coast. The region has various endemic plant species with affinities to the tropics, the Antarctic and the Andes. About 95% of the plant species are Chilean endemic, including Gomortega keule, Pitavia punctata, Nothofagus alessandrii and Jubaea chilensis. The Chilean matorral has several threatened plant species; some endangered species are Adiantum gertrudis, Avellanita bustillosii and Beilschmiedia berteroana. There are seven endemic birds found at altitudes ranging from rocky slopes to arid scrub. The ecoregion has been severely affected by fire, mining, logging, garbage dumps, urbanization, and pollution of air, water and soil. Unfortunately this is the least protected region in Chile.
Location and General Description
Types and Severity of Threats
Justification of Ecoregion Delineation
This long and narrow ecoregion is bound on the weste by the Pacific Ocean and on the east by the southern Andes. This ecoregion represents the transitional habitat between the ultra-dry Atamacama Desert to the north, and the moist Valdivian temperate forests to the south. The northern linework follows Simmonetti and Montenegro (1994) who delineate the Atacama Desert, and the southern linework originated from expert opinion during several priority setting workshops for the Valdivian ecoregion complex (Valdivia, Chile, April 19-21, 1999 and Concepción, Chile, March 24, 2000). Justification for this ecoregion can be found in its many endemic plants and unique species associations (Mittermeier at al. 1999; WWF & IUCN 1997).
