The flora of Chile is diverse and unique, influenced by the country's varied climates and geography. It includes over 5,000 plant species, many of which are endemic, meaning they are found nowhere else in the world. The northern regions feature arid desert plants, while the central areas host Mediterranean vegetation, and the southern regions are rich in temperate rainforests. Key plant families in Chile include Asteraceae, Fabaceae, and Cactaceae. Notable species include the Araucaria araucana, also known as the monkey puzzle tree, and the Copihue, Chile's national flower. Conservation efforts are essential to protect this rich biodiversity from threats like climate change and habitat loss.
