The 'Chilean Matorral' is a
terrestrial ecoregion of central
Chile, located on the west coast of
South America. It is a
Mediterranean forests, woodlands, and shrub ecoregion, part of the
Neotropic ecozone.
The
Matorral is characterized by a temperate Mediterranean climate, with rainy winters and dry summers. It is one of the world's five Mediterranean climate regions, which are all located in the middle latitudes on the west coast of continents. The
Mediterranean Basin, the
California chaparral and woodlands ecoregion of
California and
Baja California, the
Cape Province of
South Africa, and southwestern corner of
Australia are the other Mediterranean climate regions.
Setting
The Matorral occupies central Chile between 32º and 37º south latitude. The
Pacific Ocean lies to the west, and the Chilean Coastal Range lies parallel to the coast. The Chilean Central Valley lies between the Coastal range and the
Andes Mountains, which bound the Matorral ecoregion on the east. To the north is the extremely dry
Atacama desert, which separates the Matorral from the tropical forests of northern South America. A semi-desert region known as ''
El Norte Chico'', (the "little north") lies between 28º and 32º south latitude, and is the transition zone between the Atacama desert and the Matorral. To the south lies the cooler and wetter
Valdivian temperate rain forests ecoregion, which includes most of South America's
temperate rain forests.
Flora and fauna
The Chilean Matorral ecoregion is home to several plant communities.
★ 'Coastal Matorral' is a low, soft
scrubland which extends from
La Serena in the north to
Valparaiso in the south. Typical species are the coastal daisy ''(Bahia ambrosioides)'', Palhuén ''(Adesmia microphylla)'', and Palo de Yagua, the wild coastal fuchsia ''(Fuchsia lycioides)''. The coastal matorral is similar to the
garrigue of the
Mediterranean Basin and the
coastal sage scrub of
southern California.
★ 'Matorral' is a
shrubland plant community, composed of
sclerophyll ("hard-leaved") shrubs and small trees,
cactus, and
bromeliads. Typical species include Litre
''(Lithraea venenosa)'', Quillay or Soapbark Tree ''(
Quillaja saponaria)'', cactus ''(Echinopsis chiloensis)'', and bromeliads of genus ''
Puya'', with a diverse understory of herbs, vines, and
geophytes. The matorral is similar to the
chaparral of California and the
maquis of the Mediterranean Basin.
★ 'Espinal' is a
savanna plant community, composed of widely-spaced clumps of trees, predominantly Espino ''(
Acacia caven)'' and spiny carob tree ''(
Prosopis chilensis),'' with an understory of annual grasses introduced from the Mediterranean Basin in the
16th century. Much of the espinal was formerly matorral, degraded over the centuries by intensive grazing of sheep, goats, and cattle.
★ 'Sclerophyll woodlands and forests' were once more extensive, but now exist in small patches in the coast ranges and Andean foothills. The sclerophyll forests and woodlands are composed predominantly of evergreen sclerophyll trees, including Peumo ''(
Cryptocarya alba)'',
Boldo ''(Peumus boldus)'',
Mayten ''(
Maytenus boaria)'', and Chilean Wine Palm ''(
Jubaea chilensis)''.
The ecoregion has many
endemic plant species, with affinities to the South American tropics, the
Antarctic flora, and the Andes. About 95% of the plant species are endemic to Chile, including ''
Gomortega keule'', ''
Pitavia punctata'', ''
Nothofagus alessandrii'', and the Chilean Wine Palm, ''Jubaea chilensis''.
Conservation
The Matorral contains the majority of Chile's population and largest cities. The
Central valley is Chile's main agricultural region, and the region is also subject to extensive grazing, logging, and urbanization. Of Chile's ecoregions, the Matorral is the least protected by national parks and preserves.
