Maulino forest is a temperate forest formation in central Chile characterized by a mosaic of sclerophyllous and deciduous woodland dominated by endemic Nothofagus species. It lies within the transitional zone between the Chilean Matorral, the Valdivian temperate rainforest and the Mediterranean Basin (climate), forming a biogeographic link important for biodiversity and endemism. The landscape has been shaped by past Pleistocene climatic oscillations, Spanish colonization, and modern land use change driven by forestry and agriculture.
The forest occurs primarily in the Maule Region of central Chile and extends into parts of the O'Higgins Region, occupying hills and coastal ranges near the Pacific Ocean and the Andes, including the Coastal Cordillera (Chile) and intermontane valleys. Remnant patches are found near towns and communes such as Rancagua, Talca, and Curicó and within protected areas like the Parque Nacional Radal Siete Tazas and several private biological reserves. Elevational range spans low foothills to mid-elevation slopes where it interfaces with sclerophyllous scrub and exotic plantation forests.
Climate is strongly Mediterranean with cool, wet winters influenced by the westerlies and dry summers modulated by the South Pacific High and occasional El Niño–Southern Oscillation variability. Mean annual precipitation varies locally, with orographic enhancement on coastal ranges and rain shadows toward the Central Valley (Chile). Soils derive from diverse parent materials including volcanic ash, metamorphic bedrock, and alluvial deposits; common soil orders include Ultisol-like and Andisol-like profiles supporting mixed temperate forest vegetation. Microclimates created by topography and proximity to the Pacific Ocean sustain refugial conditions for humid-adapted taxa.
Vegetation is characterized by canopy species such as Nothofagus glauca, Nothofagus alessandrii, and associated trees like Acacia caven, Cryptocarya alba, and evergreen associates found in the Chilean Winter Rainfall–Valdivian Forests biodiversity hotspot. Understory communities include woody shrubs, ferns, and mosses that harbor endemic bryophytes and lichens. Faunal assemblages include birds such as the Chilean pigeon (Patagioenas), Chucao tapaculo, and Magellanic woodpecker-related guilds, mammals like the Kodkod, Puma concolor, and small marsupials, and a rich invertebrate fauna including endemic beetles and lepidopterans. Many taxa show biogeographic affinities with southern temperate forests and with Mediterranean elements.
Remaining fragments face threats from conversion to Pinus radiata and Eucalyptus plantations promoted by the national forestry sector, fragmentation by agricultural expansion, and infrastructure development tied to regional urban centers. Invasive plant species and altered fire regimes exacerbate loss of native cover, while climate change projections for central Chile suggest increased drought stress and shifts in species distributions. Legal protection is patchy; some stands occur within national parks and private reserves, while others rely on conservation initiatives by NGOs and scientific institutions such as universities and botanical gardens.
Local communities, including indigenous Mapuche groups and rural inhabitants, have traditional uses for native trees for timber, fuel, and non-timber products, and cultural associations linked to ancestral territories and cosmologies. Colonial and Republican era land tenure changes promoted sheep grazing and agriculture in the Central Valley (Chile), altering forest extent. Contemporary rural economies combine smallholder agriculture, plantation forestry for export markets, and ecotourism ventures connected to regional cities and national transportation corridors.
Restoration strategies combine active planting of native trees like Nothofagus alessandrii and assisted natural regeneration, control of exotic plantations, and creation of biological corridors to link fragments across agricultural matrices. Management involves collaboration among municipal governments, academic research programs, conservation NGOs, and private landowners, drawing on restoration ecology principles and adaptive management frameworks developed in Chilean temperate systems. Payment for ecosystem services schemes and legal mechanisms such as protected area designation have been used to incentivize conservation.
Scientific work on these forests spans paleoecology, population genetics of endemic trees, landscape ecology, and applied restoration, with contributions from Chilean universities, national research centers, and international collaborators. Monitoring programs employ satellite remote sensing, permanent plots, and biodiversity inventories to track changes in cover, carbon stocks, and species occurrence in response to land use and climate drivers. Long-term studies document successional trajectories after disturbance and inform policies on invasive species control, fire management, and connectivity planning.
