FACTS ON THE CERRADO
Land Areas: From approximately 2,031,990 square kilometers originally to 438,910 square kilometers today.
Countries: Almost entirely in Brazil, though it extends a little into Paraguay and Bolivia.
Biodiversity: 10,400 species of plants, nearly half of which are endemic; 935 species of birds; 780 freshwater fish;113 amphibians; 180 reptiles; and almost 300 mammal species. In three insect orders surveyed: 14,425 species have been catalogued.
Extent of Habitat Cover: Just over 21 percent of the cerrado remains.
Habitat Loss Rate: 21,000 square kilometers of cerrado was destroyed annually between 2002 and 2008, twice the rate of the Amazon rainforest. Between 1984 and 2004, the cerrado ecosystem declined by 1.1 percent every year.
Causes of Habitat Loss: Mechanized soy farms, cattle ranches, and some other crops.
OVERVIEW: THE CERRADO
The cerrado is a vast tropical and subtropical biome covering more than 20 percent of Brazil, it includes a number of ecosystems from tall closed forests to marshlands to open grassland. The largest savannah in South America, the name of the ecosystem, cerrado, translates as 'closed', and the region was long-considered by Brazilians as essentially worthless land. That was until the 1960s when farmers from the US began conditioning the soil with the chemical lime, improving its quality and growing capacity, and thereby transforming the savannah into agricultural fields.
Now the cerrado is one of Brazil's most threatened ecosystems. Half of the ecosystem has been destroyed for mechanized soy farms and cattle ranches. Over the past decade, two million hectares of the cerrado vanished every year to agriculture and pasture. Conservationists predict the possibility of a complete eradication of the ecosystem by 2030.
Long ignored by conservationists and environmentalists the cerrado is home to a shocking number of species, even given comparisons to its biologically-rich neighbors: the Amazon and the nearly-vanished Atlantic Forest. Of the ecosystems' some 10,000 species of plant, nearly half are endemic to the cerrado. Nearly a thousand birds and three-hundred mammals have been recorded in the cerrado as well. For a wooded savannah ecosystem with a long dry season, the cerrado is extremely rich in life.
Researchers have also begun to recognize the cerrado's importance for Brazil's waterways, since the headwaters of many of the nation's rivers begin in this savannah. The ecosystem plays an important role in carbon-cycling. In some years, carbon emissions from the destruction of the cerrado can exceed those from the destruction of the Amazon.
POLITICAL GEOGRAPHY OF THE CERRADO
The cerrado lies almost entirely in Brazil, though a small extent reaches into northeastern Paraguay and eastern Bolivia.
The ecosystem covers a number of central Brazilian states including Mato Grosso, Mato Grosso do Sul, Goiás Distrito Federal, and Tocantins; as well as western Minas Gerais and Bahia; southern Maranhão and Piauí; and small portions of São Paulo and Paraná.
ECOSYSTEMS OF THE CERRADO
The cerrado is tropical savannah characterized by the annual average temperature of 68 degrees Fahrenheit (20 degrees Celsius) to nearly 79 degrees Fahrenheit (26 degrees Celsius). The dry colder season extends from May to October. The soil is mostly nutrient poor.
The cerrado biome is home to a variety of ecosystems, including dry forests, grasslands, wetlands, shrublands, savannah, gallery forests, and even wet forests.
Gallery forests are trees and vegetation that line rivers and other waterways in otherwise savannah-type landscapes.
BIODIVERSITY PROFILE OF THE CERRADO
The cerrado is home to a surprising level of biodiversity, in fact some experts have stated that it is the most biologically rich savannah in the world. The region includes megafauna like jaguar, giant anteater, maned wolf, the greater rhea, and the giant armadillo, but the biggest stand-outs are the region's diverse plants and insects.
In total, researchers have found nearly 300 species of mammals, 780 fish, 300 amphibians and reptiles, and 935 species of bird in the cerrado region. In addition, over 14,000 species of insect have been identified from just three insect orders out of 32: Lepidoptera (butterflies and moths), Hymenoptera (ants, bees, wasps, and sawflies), and Isoptera (termites).
But the biggest biological stunner of the cerrado is its plant species: 4,400 of the cerrado's 10,000 species of plants are found no-where else in the world. Due to a long dry season, these plants have evolved remarkable resistance both to fire and drought.
The uniqueness of the cerrado's plant life—and the rampant destruction of the ecosystem—makes these species especially vulnerable to extinction. A recent study estimated that plant species in the cerrado are twice as likely to go extinct than plants in other Brazilian ecosystems, including the Amazon.
New species are still being found in the cerrado: in 2007 two new species of lizard were described by researchers and in 2008 researchers announced the discovery of 14 species new to science: 8 fish, 3 reptiles, a bird, and even a new mammal.
While new species are being discovered, others have gone extinct. The candango mouse (Juscelinomys candango) was first described in 1965, but hasn't been seen since losing all of its habitat to urban development and suburban sprawl in Brasilia.
Some largely endemic species of the cerrado include:
- The dwarf tinamou (Taoniscus nanus) is a small bird endemic to the cerrado. It is listed as Vulnerable by the IUCN Red List due to habitat loss.
- The maned wolf's (Chrysocyon brachyurusrange) range is almost entirely found in the cerrado. Reddish in color this canid boasts long-legs likely for stalking and hunting in tall grasses. It is listed as Near Threatened by the IUCN Red List also due to habitat loss.
- The cerrado boasts 26 species of the reptiles known as snake-lizards in the genus Amphisbaenidae. Underground dwellers, most Amphisbaenas are without limbs. Six of these snake-lizards are known only in the cerrado.
- The white-winged nightjar (Eleothreptus candicans) is listed as Endangered by the IUCN Red List. As their name implies nightjars are most active after dark or during twilight and early morning.
- Americas' heaviest bird, the greater rhea (Rhea americana) haunts much of the cerrado. Males of this ostrich-like bird are the sole care takers of offspring. Like another megaufauna of the cerrado, the maned wolf, the greater rhea is considered Near Threatened.
CERRADO LOSS
The cerrado is disappearing twice as fast as the Amazon rainforest with 21,000 square kilometers (over 2 million hectares) of savannah destroyed annually between 2002 and 2008.
A 2007 Conservation International study found that by 1985, 27 percent of the cerrado was lost. In less than twenty years (2004) the percentage lost rose to 57. During that time the cerrado declined 1.1 percent every year, while the Brazilian Amazon declined by less than 0.5 percent per year over the past decade.
CURRENT THREATS TO THE CERRADO
While there are not numerous threats against the cerrado, the threats that remain are massive in terms of impact and habitat loss. Mechanized soy farming and livestock rearing have caused the loss of half of the cerrado, most of which has occurred in the last 50 years after an agricultural revolution in the 1960s when chemical lime was added to the nutrient-poor soils. Brazil's government pushed such development by constructing a new captial city, Brasilia, in the state of Goias; this included building highways and infrastructure that made shipping agricultural and livestock products easy and cheap. Today only 21 percent of the original cerrado remains.
In addition, the spread of soy and other crops (corn and rice) have indirectly impacted the Amazon rainforest: a boom in agriculture has pushed livestock from the cerrado into the Amazon's edges leading to continuing deforestation of the world's biggest rainforest.
PROTECTED AREAS IN THE CERRADO
To date approximately 7.5 percent of the cerrado is under protection.
Chapada dos Veadeiros National Park: Located in the state of Goias, Brazil, Chapada dos Veadeiros National Park spreads over 655 square kilometers on some of Brazil's highest plateaus. Sporting large canyons, dramatic mountains, and stunning waterfalls, this protected area in the cerrado has been listed as a UNESCO World Natural Heritage Site.
Emas National Park: Named after the greater rhea, Emas National Park is also a UNESCO World Natural Heritage Site. Home to rhea, jaguar, giant anteater, maned wolf, and pumas, the park, which is dominated in part by termite mounds, lies in central western Brazil and covers 1,300 square kilometers.
Serra do Tombador Nature Preserve: This is a private reserve created by the Nature Conservancy and the Brazilian organization, O Boticario. Covering 89 square miles kilometers, the reserve is small compared to some of the National Parks but represents a non-government designated protected area. The Nature Conservancy hopes to establish a corridor between the Serra do Tombador Nature Preserve and Chapada dos Veadeiros National Park.

This species of lizard of the genus Bachia is one of the new species discovered during the expedition. Although there are other species of the genus in the Cerrado (almost all discovered and described only recently), this new species has only been recorded in the Ecological Station. The absence of legs and the sharply pointed snout help in locomotion over the surface layer of sandy soil, predominating in all the Jalapao, formed by the natural erosion of the escarpments of the Serra Geral plateaus.

Some of the recorded species are relatively rare and little known, like this small fat-tailed mouse opossum of the genus Thylamys, registered for the first time in the Jalapao. Although this species was described from a Cerrado enclave within the Caatinga region, recent surveys have shown that the range of this species is concentrated in the northern portion of the Cerrado savannas.

Other species such as this horned toad believed to be new to science of the genus Proceratophrys occupy very restricted areas. Protected areas like the EESGT are fundamental, because they shelter large populations of the species, reducing the threat of extinction from destruction of the habitats outside the reserves.

THE LATEST CERRADO NEWS FROM MONGABAY
Study warns that loosened legislation is driving deforestation in Bahia’s Cerrado
- Unlike Amazonia, where illegality is the rule, authorized deforestation is a greater concern for researchers and environmentalists in Bahia’s Cerrado.
- A new book shows how the appropriation of water by agribusiness is intensifying conflicts in western Bahia, where both deforestation and cattle farming are spreading rapidly.
- Researchers view Brazilian agribusiness operations as agrarian extraction—a model with high social and environmental impact which concentrates wealth, similar to mineral extraction.
NGOs ask to include Brazilian Cerrado in the EUDR at next review
- About 74% of the Brazilian Cerrado falls outside the scope of the EU Deforestation Regulation (EUDR).
- Unless illegalities are found, such as breaches to national law, commodities from areas of the Cerrado that are excluded from the EUDR will be able to enter the EU.
- Deforestation rates in the Cerrado increased by 43% in 2023, with the greatest destruction concentrated in Brazil’s state of Bahia, where almost a quarter of its original 9 million hectares (22 million acres) of vegetation have been lost since 1985.
- NGOs are calling on EU authorities to review and expand the regulation at its one-year review period. However, the European Commission recently proposed a 12-month delay in the implementation of the EUDR, which could affect the date of the review.
Report exposes meatpackers’ role in recent chemical deforestation in Brazil
- A new report links Brazil’s top meatpackers — JBS, Marfrig and Minerva — to widespread deforestation across the Pantanal, Amazon and Cerrado; of five farms investigated between October 2023 and February 2024, 86% of the destruction occurred in the Pantanal.
- Fazenda Soberana ranch is at the center of environmental controversy and is under investigation for using toxic herbicides to destroy tens of thousands of hectares of native vegetation, marking the largest environmental crime in Mato Grosso state history.
- Major meatpackers are criticized for failing to fully monitor indirect suppliers and for not ensuring that their supply chains are free from socioenvironmental violations.
- The report calls for supermarkets to cut ties with meatpackers linked to deforestation and for full transparency regarding the origin and supply chains of beef products.
Brazil launches ‘war’ on widespread fire outbreaks & criminal arsonists
- Fire outbreaks are setting records all over Brazil, with flames burning the Amazon, the Cerrado, the Pantanal and the São Paulo state.
- Federal authorities say most fires are criminal and they are launching investigations.
- Smoke from fires spread through 10 Brazilian states, impacting air quality and air traffic.
Streak of falling deforestation snapped at 15 months in Brazil’s Amazon rainforest
- Deforestation in the Brazilian Amazon increased in July 2024, marking the first month-over-month rise since March 2023, with 666 square kilometers of forest destroyed.
- Despite the recent increase, deforestation is still 46% lower this year compared to last year on a 12-month rolling basis, though severe drought and wildfires have worsened conditions.
- Cerrado deforestation has declined for four consecutive months but remains near a five-year high.
- The Brazilian government is expected to release a preliminary official deforestation figure for the year ending July 31, 2024, later this year, timed to coincide with minimal cloud cover for accurate year-over-year comparisons.
Brazil’s new pro-agribusiness pesticide law threatens Amazon biodiversity
- A priority project of Brazil’s congressional agribusiness caucus, the so-called Poison Bill eases restrictions on the sale and use of a wide range of agrochemicals dangerous to humans and the environment.
- The bill went into effect as the use of pesticides banned long ago in the European Union exploded in the Brazilian Amazon.
- In the rainforest, use of the fungicide mancozeb skyrocketed by 5,600%, and the use of the herbicide atrazine increased by 575% in just over a decade.
- Experts warn that lax pesticide controls will worsen impacts at the edge of the Amazon, where the chemicals affect intact biodiversity and aggravate risks to Indigenous people, riverside communities and small farmers.
Living under the apartheid of Brazil’s soybean capital
- Brazil produces more soybeans than any other nation, and the city of Sorriso, Mato Grosso, leads this production, which drove the municipal per capita GDP from 27,000 reais to 132,000 reais ($15,800 to more than $25,000) in the last 10 years.
- The highway running through town helps illustrate the contrast between gated communities of luxury homes along one side and precarious homes where agricultural workers and family farmers live amid vulnerable social situations on the other.
- Family farmers struggle to keep producing amid land disputes and clouds of pesticides that destroy their crops, ruin honey production and raise cancer rates — which are twice as high in Sorriso than the state average.
- Lives are also lost to organized crime in Sorriso, the municipality with the sixth-highest murder rate in the nation, and also to agribusiness itself, with dozens dead after becoming engulfed in soybean silos.
New ban threatens traditional fishers in Brazil’s Mato Grosso state
- Legislation in effect since Jan. 1 has banned fishing in Mato Grosso state rivers for five years, with heavy opposition from environmental defenders and traditional fishers.
- The bill affects part of the Brazilian Amazon Rainforest, the Cerrado savanna and part of the Pantanal wetland, one of the largest continuous wet areas on the planet.
- Experts consider fishers in the region guardians of the rivers and fear the bill could eliminate traditional fishing in the state.
Goldman Prize honors Brazilian investigation linking JBS & deforestation
- Marcel Gomes, the executive secretary at investigative journalism outlet Repórter Brasil, is one of this year’s prestigious Goldman Environmental Prize winners.
- Gomes coordinated an international investigation in December 2021 on JBS’ beef chain, using a powerful data platform on Brazilian livestock, investigative teams in different countries and a grassroots network of Indigenous communities, local NGOs and small-scale farmers.
- In an interview with Mongabay, Marcel Gomes said the Repórter Brasil series pressured big European retailers to stop selling illegally sourced JBS beef and public authorities to monitor big beef companies.
- Also known as the “Green Nobel Prize,” the Goldman Environmental Prize honored five other environmental activists on April 29.
Tapirs in Brazil’s Cerrado inspire research on human health & pesticides
- Recent research has revealed human contamination by pesticides in the Brazilian Cerrado, following a previous study that also found contamination in tapirs in the region.
- This research shows how animals are providing information and inspiration for research with humans, while emphasizing that the stress endured by South America’s largest terrestrial mammal is also evidenced in people.
- Despite inspiring research on human health, tapirs themselves are not free from the challenges to their survival imposed by human actions; the species is classified as threatened by the IUCN Red List and qualified as vulnerable to extinction.
- The former president of the Brazilian federal environmental protection agency, IBAMA, says the approval of a bill that made the use of pesticides more flexible in Brazil could worsen situations like those reported by the researchers.
Brazil’s Cerrado is main beneficiary of 2021 pledge to end deforestation
- The Financial Innovation for Amazonia, the Cerrado and Chaco, or IFACC, has allocated $234.5 million for projects aimed at expanding agriculture to already deforested land in Brazil’s Cerrado grasslands.
- First announced at the COP26 climate summit in 2021, the initiative aims to place small farms on the sustainability agenda by showing that it’s possible to increase profit without clearing native vegetation.
- Funded projects include soybean farming on degraded pastureland and financial incentives for farmers who maintain more preserved native vegetation on their land than the minimum required by law.
Deforestation from soy shows no sign of stopping in Cerrado, report says
- A recent report from Mighty Earth shows that approximately 26,901 hectares (66,473 acre) suffered deforestation and forest degradation in the Cerrado between last September and December, while 30,031 hectares (74,208 acres) were affected in the Amazon.
- Mighty Earth, in partnership with AidEnvironment and Repórter Brasil, are monitoring short-term soy and cattle ranching activities contributing to deforestation, aiming to highlight recent forest loss cases every three months.
- The report called for improved regulations that protect savanna biomes like the Cerrado, not just the Amazon Rainforest.
Major meatpackers are unlawfully deforesting Brazil’s Cerrado, report says
- In the state of Mato Grosso, some of the country’s largest meatpackers are clearing parts of the Cerrado at an even faster rate than the Amazon Rainforest, a new report from U.K.-based NGO Global Witness says.
- Meatpackers JBS, Marfrig and Minerva have cut down nearly five times more of the state’s Cerrado than they have its Amazon. One in three cows that the companies purchased from the Cerrado had grazed on illegally deforested land.
- A major EU law regulating deforestation in supply chains is scheduled for review this year, and the Global Witness report said its language should be expanded to include “other wooded land” that would protect the Cerrado.
Outcry as Brazil Congress overrides president to revive anti-Indigenous law
- Brazil’s Congress has pushed through a new law that includes several anti-Indigenous measures that strip back land rights and open traditional territories to mining and agribusiness.
- It includes the controversial time frame thesis, requiring Indigenous populations to prove they physically occupied their land on Oct. 5 1988, the day of the promulgation of the Federal Constitution; failure to provide such evidence will nullify demarcated land.
- The decision provoked outrage among activists, who say the new law is the biggest setback for Indigenous rights in Brazil in decades.
- Both President Lula and the Supreme Court have previously called the measures in the bill unconstitutional and against public interests, and Indigenous organizations announced they will challenge the law.
Deforestation falls for 8th straight month in the Amazon rainforest, but rises in the cerrado
- Deforestation in the Brazilian Amazon has decreased for the eighth consecutive month, but damage is rising in the cerrado, a tropical woody grassland that’s adjacent to Earth’s largest rainforest.
- According to data released today by Brazil’s National Space Research Institute (INPE), forest clearing in November totaled 201 square kilometers, bringing the cumulative loss for the past 12 months to 5,206 square kilometers – 51% less than last year.
- The decline in deforestation has persisted despite one of the most severe droughts ever recorded in the Amazon.
- However, while deforestation in the Amazon rainforest has decreased, it has reached the highest level in at least five years in the cerrado.
Cargill widens its deforestation-free goals, but critics say it’s not enough
- Cargill has announced its Brazil, Uruguay and Argentina supply chains will be free of deforestation and land conversion by 2025.
- The commitments also expand to all row crops in those countries, including soy, corn, wheat and cotton.
- While conservation groups have welcomed the expanded commitment, they say it still leaves out countries like Bolivia, Paraguay and Colombia, where deforestation from the expanding agricultural frontier continues to increase.
Glyphosate leaves its mark even in protected areas of Brazil’s Cerrado
- A study found lichens dying as a result of exposure to glyphosate in an ostensibly protected area in Brazil’s Goiás state.
- Formed by interaction between fungi and algae, lichens are bioindicators of air quality.
- Glyphosate is the top-selling herbicide in Brazil and the world, used intensively in soybean, corn and sugarcane plantations; around 70% of pesticides sold in the country are applied in the Cerrado grassland biome.
- The study confirms the dispersion of the product into conservation areas from farmland, with aerial spraying a major factor for this so-called drift.
A tale of two biomes as deforestation surges in Cerrado but wanes in Amazon
- Brazil has managed to bring down spiraling rates of deforestation in the Amazon Rainforest in the first half of this year, but the neighboring Cerrado savanna has seen a wave of environmental destruction during the same period.
- The country’s second largest biome, the Cerrado is seeing its highest deforestation figure since 2018; satellite data show 3,281 hectares (8,107 acres) per day have been cleared since the start of the year through Aug. 4.
- The leading causes of the rising deforestation rates in the Cerrado are a disparity in conservation efforts across Brazil’s biomes, an unsustainable economic model that prioritizes monocultures, and escalating levels of illegal native vegetation clearing.
- Given the importance of the Cerrado to replenish watersheds across the continent, its destruction would affect not just Brazil but South America too, experts warn, adding that the region’s water, food and energy security are at stake.
Sweet solution: Armadillo-friendly honey helps Brazil beekeepers, giant armadillos
- Giant armadillos in Brazil have been spotted destroying bee hives in search of larvae, causing economic losses to beekeepers and consequent retaliatory killings.
- The species has a low population growth rate, meaning human-wildlife conflicts like these significantly threaten their survival.
- One NGO promotes coexistence between beekeepers and giant armadillos by certifying beekeepers who use mitigation measures to prevent attacks on beehives, allowing them to sell armadillo-friendly honey at a higher price.
- The armadillo-friendly honey project has been applied within the Cerrado savanna and is now being implemented within the Amazon Rainforest region, zeroing armadillo killings in the apiaries involved in the scheme.
Lula wants to mirror Amazon’s lessons in all biomes, but challenges await
- A new decree intends to protect all of Brazil’s biomes and promote sustainable development in arguably one of the country’s most ambitious environmental policies to date.
- The mandate establishes action plans for the Amazon Rainforest, Cerrado savanna, Atlantic Forest, semi-arid Caatinga, Pampas grasslands and Pantanal wetlands, based on past strategies in the Amazon that have already proven successful against deforestation.
- Environmentalists have welcomed the decree amid the country’s surging deforestation levels and rising greenhouse emissions during the past four years under Jair Bolsonaro’s rule.
- The decree’s implementation won’t be easy, experts warn, and its success depends on coordinated action across all levels of the government, increased personnel in struggling environmental enforcement agencies and highly tailored plans for each biome.
