Much of Chile is included in the Chilean Winter Rainfall-Valdivian Forests biodiversity hotspot (CEPF). In addition to mainland areas this hotspot includes the island ecoregions of the Juan Fernández Islands Temperate Forests (EoE) and the San Félix-San Ambrosio Islands Temperate Forests (EoE). The marine fauna of Easter Island is considered one of the world's most important marine centers of endemism (Columbia Univ. pdf file).
