Brazilian cerrado The cerrado is a vast Neotropical savanna ecoregion occupying central Brazil and extending into adjacent areas of Bolivia and Paraguay. It features a mosaic of wooded savannas, grasslands, gallery forests and wetlands shaped by ancient soils, pronounced dry seasons and frequent fire regimes. The region underpins major Brazilian agricultural frontiers, hosts exceptional biodiversity, and is the focus of national and international conservation efforts involving bodies such as the Ministry of the Environment (Brazil) and international organizations.
Geography and climate
The ecoregion spans central Brazilian states including Goiás, Mato Grosso, Mato Grosso do Sul, Minas Gerais, Bahia, Tocantins, Distrito Federal and parts of São Paulo and Pará, forming plateaus and intermontane depressions across the Brazilian Highlands. Major river systems such as the Tocantins River, São Francisco River, Araguaia River and tributaries of the Amazon River and Paraná River drain the landscape, while gallery forests follow waterways. The climate is predominantly tropical seasonal with a pronounced dry season (May–September) and a wet season (October–April) under the influence of the South Atlantic Convergence Zone, with mean annual rainfall varying from ~800 mm to >2,000 mm and mean temperatures often 20–26 °C.
Flora and fauna
Vegetation types range from open grasslands (campo limpo) and shrub-dominated savannas (cerrado sensu stricto) to wooded savannas (cerradão) and riparian gallery forests (mata de galeria). Soils are typically acidic, oxisols and ultisols with low fertility, favoring sclerophyllous and deep-rooted species such as members of the families Fabaceae, Myrtaceae, Vochysiaceae and Poaceae. Iconic plant genera include Caryocar, Qualea, Ouratea and Byrsonima, while endemic herbs and orchids contribute to high plant endemism. Faunal assemblages include large mammals such as the Maned wolf, Giant anteater, Tapir, and jaguar populations connected to the Pantanal; avifauna includes the Hyacinth macaw and diverse passerines; reptiles and amphibians show high regional endemism; and diverse insect communities, including pollinators and herbivores, shape ecosystem processes.
Human history and indigenous peoples
Indigenous groups traditionally occupying cerrado landscapes include representatives of linguistic families such as the Tupi, Arawak, Jê and Karajá, who practiced seasonally mobile harvesting, shifting cultivation and complex fire management. Colonial and imperial eras saw incursions by Portuguese colonizers and bandeirantes into interior Brazil, leading to demographic shifts, missionization by orders like the Jesuits, and integration into trade networks centered on Gold Rushes (Brazil) and cattle ranching. Twentieth-century state policies promoting frontier occupation—linked to projects such as the Trans-Amazonian Highway and agricultural modernization under Plano de Metas—accelerated settlement, commodity production and socio-environmental change, affecting traditional livelihoods and land tenure conflicts adjudicated in institutions like the National Institute for Colonization and Agrarian Reform.
Agriculture, land use, and economic importance
Since the late twentieth century the cerrado has been a primary arena for Brazil's agribusiness expansion, with mechanized cultivation of soybeans, irrigated sugarcane and extensive cattle ranching becoming dominant land uses. Infrastructure developments including roads, highways, and irrigation schemes facilitated integration with export markets and commodity chains centered in ports such as Santos' terminals. Scientific and technological interventions—from soil correction with lime and phosphate inputs to plant breeding at institutions like the Embrapa research network—enabled large-scale conversion of native vegetation into croplands and pastures, producing major contributions to Brazil's role in global food supply and biofuel markets while generating regional socio-economic transformations.
Conservation, threats, and restoration
The cerrado is classified as a biodiversity hotspot under high threat from agricultural conversion, fragmentation, fire regime alteration and hydrological change due to dam construction and groundwater extraction. Protected areas and conservation initiatives include federal and state parks, private reserves under mechanisms influenced by the Forest Code (Brazil) and international conservation projects involving entities such as the World Wide Fund for Nature and Conservation International. Threats also involve invasive species, urban expansion around metropolitan regions like Brasília and pesticide impacts linked to agribusiness supply chains. Restoration strategies combine passive regeneration, assisted natural regeneration, active planting using native germplasm banks, and payment for ecosystem services schemes implemented in partnership with agencies like the Brazilian Development Bank to restore habitat, connectivity and hydrological function.
Research and ecological significance
The cerrado serves as a model system in studies of savanna ecology, fire ecology, plant functional traits and nutrient-poor soil adaptation, producing research by universities such as the University of São Paulo, Federal University of Goiás and international collaborations with institutions like the Smithsonian Institution. Long-term ecological research has addressed carbon storage, biodiversity patterns, and socio-ecological resilience under climate change scenarios projected by groups including the Intergovernmental Panel on Climate Change. Applied research in agronomy, restoration ecology and landscape planning informs policy dialogues at forums like the Convention on Biological Diversity and national biodiversity strategies, highlighting the cerrado's global importance for conservation, climate mitigation and food security.
