Wildlife of
Minas Gerais

The Cerrado is the main biome in much of Minas Gerais, from open grasslands to shrub and woodland savannas, especially on central-west plateaus and intermontane basins, with frequent fires and poor soils.

Widespread across central, western, and parts of northern Minas Gerais; often the matrix outside major Atlantic Forest blocks.

Atlantic Forest occurs as moist montane forests and cloud-forest-like zones on eastern and southeastern highlands and escarpments, with many unique species and strong altitude turnover; in Minas Gerais often ombrophilous montane forests.

Patchy to locally extensive in the east/southeast and along humid mountain slopes; heavily fragmented outside protected areas.

Seasonal tropical forests (semi-deciduous/deciduous) occur in rain-shadow valleys and between Cerrado and Atlantic Forest, and farther north where drier. Patches on limestone or rich soils remain; trees lose many leaves in dry season.

Scattered belts and fragments across central/eastern interior valleys and more strongly toward the north/northeast; much reduced by agriculture and pasture.

Large headwater and river systems in Minas Gerais support diverse fish and riparian life: clearwater/blackwater Cerrado streams, rocky montane headwaters, and rivers feeding São Francisco, Paraná/Grande, Doce, and Jequitinhonha basins. Riparian corridors link fragmented landscapes.

Statewide via dense river networks; highest ecological importance in headwaters and intact riparian stretches.

Wetlands include Cerrado 'veredas' (palm swamps dominated by buriti), wet grasslands in valley bottoms, riparian floodplains, marshy headwater seeps, and reservoir-edge wetland mosaics. These are biodiversity hotspots and key dry-season water sources.

Localized but widespread in suitable valley bottoms and along drainage lines; especially notable in Cerrado areas (central/west/north) and floodplain pockets.

Atlantic Forest remnants and seasonal forests in mosaics with agriculture and pasture; key strongholds occur in protected mountain areas (e.g., Serra do Cipó region, Mantiqueira sectors, parks in the east).

Humid Atlantic Forest on wetter slopes and higher-elevation zones (often montane/moist forest rather than coastal lowland rainforest), with epiphytes and strong altitudinal gradients.

Seasonally dry deciduous and semi-deciduous forests in interior valleys and transition zones, often on more fertile or limestone-derived soils and highly threatened by clearing.

Cerradão (dense woodland savanna) and woodland edges forming transitions between open Cerrado and forests; important for wide-ranging mammals and birds.

Open grasslands and high-elevation grasslands, including rupestrian grasslands on quartzite/ironstone substrates with many endemic plants.

Classic Cerrado savanna mosaics (open campo sujo to shrub savanna) shaped by seasonal drought, fire, and poor soils; widely distributed across central/western Minas.

Shrubby Cerrado formations and rocky scrub on shallow soils, including xeric shrub patches on exposed ridges and plateaus.

Major ranges (Espinhaço, Mantiqueira) create cool/windy ridge environments, steep gradients, and isolated habitats that drive endemism and microclimates.

Karst and limestone cave systems (notably in regions like Lagoa Santa and the Peruacu area) with specialized subterranean fauna and important bat roosts.

Rock outcrops, escarpments, and quartzite/ironstone cliffs (common in the Espinhaco Range and the Iron Quadrangle) hosting specialized plants and nesting sites for birds.

Headwater streams and major rivers (São Francisco, Grande, Doce, Jequitinhonha and tributaries) supporting riparian forests, migratory fish routes (where unobstructed), and riverine wetlands.

Natural and artificial lakes/reservoirs (hydropower and water supply) that create lentic habitats and shoreline wetland mosaics, though often with altered flow regimes.

Small ponds, cattle tanks, and seasonal pools in Cerrado landscapes important for amphibians and aquatic invertebrates during the rainy season.

Valley-bottom wetlands and seepage areas, including peatier headwater zones in some highlands and extensive wet grasslands in Cerrado depressions.

Palm swamps dominated by moriche palm and other swampy headwater wetlands that stabilize water flow and provide refuges during the dry season.

Marshes along floodplains, reservoir margins, and slow-flowing tributaries with emergent vegetation and high bird use.

Large urban centers (e.g., Belo Horizonte metropolitan region) creating heat-island effects, river channelization, and fragmented green spaces that still function as corridors when managed.

Expanding peri-urban belts with mixed housing, small farms, and secondary vegetation; often the front line of habitat fragmentation near major cities.

Pasture and crop mosaics (including coffee in suitable highland zones, grains in flatter Cerrado areas) that replace native vegetation and pressure riparian buffers.

Commercial tree plantations (notably eucalyptus and pine in some areas) that simplify habitat structure but can provide partial connectivity when managed with native set-asides.
