Ecoregions of Chile Chile contains a sequence of biomes and ecoregions spanning from the Atacama Desert to the Antarctic Peninsula, shaped by the Andes, the Pacific Ocean, and latitudinal gradients. The country's ecoregions intersect major biogeographic boundaries recognized by organizations such as the World Wide Fund for Nature and the International Union for Conservation of Nature. Chile's diversity supports iconic species associated with places like Torres del Paine National Park, Patagonia, and the Juan Fernández Islands.
Chile's ecoregions are classified within the Neotropical realm and the Antarctic realm by global schemes used in assessments by the World Wildlife Fund and the International Union for Conservation of Nature. Northern Chile features the Atacama Desert, central Chile comprises Mediterranean climate sclerophyllous scrub of the Chilean Matorral and remnants of Valdivian temperate rainforests in the Los Lagos Region, while southern Chile includes the Magellanic subpolar forests and patagonian steppe near Tierra del Fuego. Offshore, the Humboldt Current and the Chilean Sea influence marine ecoregions recognized by the Marine Ecoregions of the World project and researchers from institutions such as the University of Chile and the Pontifical Catholic University of Chile.
Terrestrial ecoregions range from hyperarid slopes of the Atacama Desert and coastal Pan de Azúcar National Park to the sclerophyll woodlands of the Chilean Matorral around Santiago, Chile and Valparaíso, through the evergreen Valdivian temperate rainforests of Los Ríos Region and Los Lagos Region with connections to the Aysén Region and Magallanes Region. Further south, the Patagonian grasslands and Magellanic subpolar forests frame landscapes around Punta Arenas and Puerto Natales, including protected areas like Parque Nacional Torres del Paine and Parque Nacional Bernardo O'Higgins. Insular ecoregions include the endemic-rich Juan Fernández Islands and Easter Island, which link historically to expeditions such as the Magellan expedition and settlements like Rapa Nui National Park.
Freshwater systems follow steep Andean gradients with catchments draining to the Pacific Ocean and endorheic basins like those in the Atacama Desert. Major freshwater ecoregions include Andean glacier-fed rivers in the Biobío Region and Los Lagos Region, high-altitude wetlands (bofedales) near San Pedro de Atacama and Altiplano lagoons connected to sites visited during Alexander von Humboldt's expeditions. Southern freshwater ecoregions support migratory fishes linked to the Salmon industry and native species threatened by introduced Oncorhynchus mykiss and Salmo salar, with research programs at the Instituto de Fomento Pesquero monitoring populations.
Chile's marine ecoregions are dominated by the cold, nutrient-rich Humboldt Current system affecting coastal productivity from Arica to Tierra del Fuego. Nearshore zones include upwelling centers by Iquique and Antofagasta that support fisheries exploited by companies based in Valparaíso and Concepción. Offshore islands yield distinct ecoregions: the Juan Fernández Islands host endemic marine assemblages, while Rapa Nui lies within a remote pelagic ecoregion studied during voyages like the Challenger expedition. Southern fjords and channels around Puerto Montt and Coyhaique create unique subpolar marine habitats connected to Antarctic ecosystems studied by institutions such as the Alfred Wegener Institute.
Chile's biogeographic provinces correspond to endemic-rich centers such as the Juan Fernández Islands, the Valdivian temperate rainforest, and the Chilean Matorral. Endemic mammals include the Monito del monte and threatened populations of the Kodkod near Chiloé Island, while endemic plants include taxa in families highlighted by botanists like Rodolfo Amando Philippi and organizations such as the International Plant Names Index. Avian endemism includes species tied to locations such as Rapa Nui and Chiloé, with conservation attention from organizations like BirdLife International.
Protected areas like Conguillío National Park, Huerquehue National Park, and Rapa Nui National Park reflect Chile's commitments under international agreements including the Convention on Biological Diversity. Threats include habitat loss from agriculture around O'Higgins Region, invasive species on the Juan Fernández Islands, glacier retreat in the Andes linked to research by the IPCC, and overfishing along the Humboldt Current exploited by fleets registered in ports such as San Antonio. Conservation initiatives involve the National Forestry Corporation (CONAF), universities like the Pontifical Catholic University of Chile, and NGOs such as World Wildlife Fund Chile.
Human land use mosaics include viticulture in the Central Valley, forestry plantations in the Los Ríos Region and Los Lagos Region operated by companies like Arauco and CMPC, and mining in the north around Antofagasta and Calama driven by enterprises such as Codelco. Urban expansion in Santiago, Chile and infrastructure associated with projects like the Pan-American Highway alter ecoregion connectivity, while indigenous groups including the Mapuche, Aymara, and Rapa Nui people manage landscapes with cultural practices recognized in instruments like the Indigenous and Tribal Peoples Convention. Climate change impacts documented by the Intergovernmental Panel on Climate Change and national agencies affect snowpack, hydrology, and species distributions, guiding policy dialogues in forums such as the United Nations Framework Convention on Climate Change.
