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.

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.

This species of amphibian (Corythomantis greeningi) occurs mainly in the Caatinga region, with only scant recordings in the Cerrado.The discovery of this species in the EESGT is the first recorded for the Jalapao region.

THE LATEST CERRADO NEWS FROM MONGABAY

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.

Protecting canids from planet-wide threats offers ecological opportunities
- Five species within the Canidae family are considered endangered. These species, while found far apart in North and South America, Asia and Africa, often share similar threats, including habitat loss, persecution, disease and climate change.
- For some at-risk canid species, loss of prey, particularly due to snaring, is a significant concern that can also exacerbate human-wildlife conflict. Ecosystem-level conservation that protects prey species populations is required to protect canids and other carnivore species, experts say.
- Conservationists and researchers emphasize that canids play important roles in maintaining the habitats in which they live. That makes protecting these predators key to restoring and maintaining functional ecosystems.
- In the face of widespread global biodiversity loss, some canid reintroductions are taking place and proving successful. These rewilding efforts are offering evidence of the importance of canids to healthy ecosystems and to reducing various ecosystem-wide threats, even potentially helping curb climate change.

To be effective, zero-deforestation pledges need a critical mass, study shows
- The importance of rapidly halting tropical deforestation to achieve net-zero emissions was a key message at this year’s climate summit, but corporate efforts to this end have stalled for decades.
- Cattle, soy and palm oil are the main commodities driving deforestation and destruction of other important ecosystems. Zero-deforestation commitments from the companies that trade in those commodities are seen as an important way to reduce deforestation globally.
- A new study compares the effectiveness of corporate commitments to reduce soy-related deforestation in the Brazilian Amazon and Cerrado, showing that zero-deforestation commitments can reduce deforestation locally, but only if there is widespread adoption and implementation among both small and big soy traders.
- Overall, the study points to the limitations of relying just on supply chain agreements to reduce regional deforestation and protect biodiverse ecosystems, and highlights the need for strong public-private partnerships.

Growing soy on cattle pasture can eliminate Amazon deforestation in Brazil
- Expanding soy cultivation into underutilized cattle pastureland would help prevent massive deforestation and carbon emissions compared to the current practice of clearing new forest for farmland, a new study says.
- Experts say that Brazil, the world’s No. 1 soy producer and beef exporter, has enough pastureland lying unused that would allow soy production to increase by more than a third without any further deforestation.
- Researchers warn that if Brazil continues with its current method of soy cultivation, it would end up clearing 5.7 million hectares (14 million acres) of Amazon rainforest and Cerrado savanna into cropland over the next 15 years.
- Environmentalists have welcomed intensifying agriculture as a solution to deforestation, but have raised concerns about the potential for increased pesticide use, biodiversity loss, and the expansion of cattle ranching into forested areas.

Habitat loss, climate change send hyacinth macaw reeling back into endangered status
- The hyacinth macaw, the world’s largest flying parrot, is closer to return to Brazil’s endangered species list, less than a decade after intensive conservation efforts succeeded in getting it off the list.
- The latest assessment still needs to be made official by the Ministry of the Environment, which is likely to publish the updated endangered species list next year.
- Conservation experts attribute the bird’s decline to the loss of its habitat due to fires in the Pantanal wetlands and ongoing deforestation in the Amazon and Cerrado biomes.
- Climate change also poses a serious threat, subjecting the birds to temperature swings that can kill eggs and hatchlings, and driving heavy rainfall that floods their preferred nesting sites.

World Bank approves $200 million IFC loan for industrial agriculture in Brazil’s Cerrado
- A $200 million loan was granted to Louis Dreyfus Company (LDC), an industrial soy and corn producer, for monoculture work in Brazil’s Cerrado, a grassland biome that has lost nearly 80% of its habitat cover.
- The loan was granted by the International Finance Corporation (IFC), a sister organization of the World Bank that’s tasked with private sector finance in developing countries.
- Corn, soy and cattle ranching have been connected to a long list of human rights violations, as well as the acceleration of deforestation and greenhouse gas emissions.

EU’s anti-deforestation bill leaves out critical ecosystems, study shows
- New regulation proposed by the European Commission aims to reduce the import of commodities that cause deforestation and forest degradation abroad.
- But according to a report commissioned by the EU Greens parliament members, the narrow definition of forest and deforestation in the revised legislation would not protect ecosystems in South America where EU demand for commodities such as soy and beef create high deforestation risk.
- Soy production is not only destroying native vegetation, but also threatens the livelihoods of hundreds of Indigenous peoples and traditional communities in the Cerrado and Chaco biomes, made of grasslands, savannas and dry forests stretching down the center of South America.
- Broadening the definition of forest to include other types of wooded land, or adopting a definition based on native vegetation rather than forest, would protect much more of the Cerrado and the Chaco, and be much more effective at tackling deforestation, the report says.

Indigenous village harvests seeds to slow deforestation in Brazil’s Cerrado
- Mato Grosso’s Cerrado forest in Brazil is supposed to be protected with set asides when logged for new croplands and pastures. However, farms often get away with protecting less than they’re supposed to.
- In the village of Ripá, Indigenous Xavante people make expeditions for harvesting fruit with seeds for replanting forests, helping to repair some of the damage and supplement their income.
- Ripá and another two dozen Indigenous communities in Mato Grosso sell their harvest to Rede de Sementes do Xingu (RSX), a wholesaler that, since 2007, has sold or given away enough seeds to replant 74 square kilometers (about 29 square miles) of degraded land.
- This story was produced with support from the Pulitzer Center.

Training on pasture recovery is a win-win for Brazil’s cattle ranchers and forests
- A recent study found that providing Brazilian cattle ranchers with customized training in sustainable pasture restoration could bring long-term economic and environmental benefits.
- Trained ranchers saw an increase in cattle productivity and revenue, and a reduction in carbon dioxide emissions over a period of two years.
- Researchers say that recovering degraded pastures could help stop deforestation for agriculture by allowing farmers to increase cattle numbers without needing more land.
- Despite government-led programs that promote sustainable agriculture, experts say pasture recovery is not yet being fully prioritized.

Tropical mammals under rising chemical pollution pressure, study warns
- Pesticides, pharmaceuticals, plastics, nanoparticles, and other potentially toxic synthetic materials are being released into the environment in ever greater amounts. A recent study warns that action is needed to better monitor and understand their impacts on terrestrial mammals in the tropics.
- Mortality and mass die offs could result, but sublethal effects — such as reduced fitness or fertility — are perhaps of greater concern in the long-term, warn experts.
- In the research, scientists raise concerns over an increasing load of chemicals released into the tropical environment, with little monitoring conducted to understand the impacts on wildlife.
- Another study released this year reported that the novel entities planetary boundary has been transgressed. Novel entities include pesticides and other synthetic substances. The boundary was declared breached because scientific assessments can’t keep up with new chemicals entering the environment.

Brazil bill seeks to redraw Amazon borders in favor of agribusiness
- A new bill before Brazil’s Congress proposes cutting out the state of Mato Grosso from the country’s legally defined Amazon region to allow greater deforestation there for agribusiness.
- Under the bill, known as PL 337, requirements to maintain Amazonian vegetation in the state at 80% of a rural property’s area, and 35% for Cerrado vegetation, would be slashed to just 20% for both.
- The approval of the bill would allow for an increase in deforestation of at least 10 million hectares (25 million acres) — an area the size of South Korea — and exempt farmers from having to restore degraded areas on their properties.
- Environmental law specialists warn that the departure of Mato Grosso from under the administrative umbrella of the Legal Amazon would set off a domino effect encouraging the eight other states in the region to push for similar bills.

In Brazil’s northeast, family farmers are guardians of creole seeds
- Families in northeastern Brazil’s Alto Jequitinhonha region have held out against industrial farming by preserving dozens of traditional seed varieties through generations of family farming.
- The tradition led to publication in 2019 of the Alto Jequitinhonha Creole Seed Catalog, which lists 132 varieties preserved and grown by 28 families in the region.
- Guaranteeing food security means dealing with several challenges in this region, including increasingly longer dry seasons as a result of climate change, and competition with eucalyptus monocultures for water.

In destroying the Amazon, big agribusiness is torching its own viability
- A new study has found that the transition zone between the Amazon and Cerrado in the northeast of Brazil has heated up significantly and become drier in the past two decades.
- The research points to deforestation in the Amazon and global climate changes as factors prolonging the dry season and warming up the region, leaving it susceptible to severe droughts and forest fires.
- Ironically, the changes being driven by the intensified agricultural activity are rendering the region less suitable for crop cultivation.
- The authors of the new study say there needs to be a balance of sustainable agricultural solutions and an environmentally focused political agenda to protect the region’s ecosystems, its economy, and its people.

Pay or punish? Study looks at how to engage with farmers deforesting the Cerrado
- Businesses and countries are renewing their commitments to reducing deforestation in supply chains, but disagreements still exist over what the most effective, efficient and equitable tools are to make that happen.
- In the Brazilian Cerrado, the world’s most biodiverse savanna, soybean production is one of the key industries driving rampant deforestation and conversion of native vegetation.
- While some observers favor the “carrot” approach of paying farmers not to deforest, others advocate for a “stick” approach that would cut market access for farmers who deforest.
- A new study says that in the case of the Cerrado, just using a stand-alone policy that pays farmers not to deforest would be expensive, inefficient and inequitable, and that some measure of market exclusion is also needed.

Is a European proposal on imported deforestation too punitive? (commentary)
- One third of global deforestation is linked to international trade, and the European Union plus the UK are estimated to account for 16% of global trade-related deforestation.
- A recent European Commission proposal would require companies to ensure that commodities placed on the European market are not linked to a territory that has been deforested after December 31, 2020.
- A senior scientist at CIRAD argues that as worded, the proposal could punish some countries unfairly while ignoring other useful certification schemes that protect forests.

As its end looms, Cerrado tracker records 6-year deforestation high
- The satellite-based deforestation-monitoring program focused on Brazil’s vast Cerrado savanna may end in April because of lack of funding, with some members of the team reportedly already laid off.
- Unlike the monitoring program for the Amazon, the one for the Cerrado isn’t included in the government budget and relies on external financing, which dried up in August 2020; since then, the program team has had to scrounge for funding from other projects and institutions.
- Sharing the scientists’ concerns is the agribusiness sector, which relies on the data to prove that its commodity is deforestation-free, and which has blasted the government’s “blurred” vision with regard to failing to fund the monitoring program.
- News of the impending closure of the monitoring program comes a week after its latest data release showed an area six times the size of the city of São Paulo was cleared between August 2020 and July 2021 — the highest deforestation rate in the Cerrado since 2015.

Brazil farming co-op carves a sustainable path through agribusiness stronghold
- Coopcerrado, a farmer’s cooperative of 5,000 families, won the United Nations’ Equator Prize under the category of “New Nature Economies” due to its more than two decades of work in developing a farmer-to-farmer model of mutual support for training, commercializing and setting up organic and regenerative businesses in the Brazilian Cerrado.
- The Cerrado savanna, a biodiversity hotspot holding 5% of the world’s biodiversity is also among one of the most threatened, with almost half of the biome destroyed for agriculture and a process of desertification already underway, scientists say.
- To save the Cerrado, farmers and traditional extractivist communities have developed an expandable model of collective support in knowledge and resource-sharing while restoring the biome and providing an income for thousands of vulnerable families.
- Bureaucratic and logistic hurdles in Brazil traditionally leave small farmers and traditional communities out of mainstream markets and industries, but bridging this gap has been one of the keys to the cooperative’s success.

Timmermans vs. Bolsonaro: Will the EU get deforestation off our dinner plates? (commentary)
- The European Commission is drafting a plan to address deforestation linked with commodity supply chains.
- But Nico Muzi, Europe Director of global environmental group Mighty Earth and member of the EU Commission Expert Group on protecting and restoring the world’s forests, argues the measure has a significant loophole for soy-based animal feed and leather from Brazil.
- “The leaked plan has several major loopholes that would substantially and unnecessarily weaken its impact even as deforestation in Brazil surges,” Muzi writes. “Even while the law would protect parts of the Amazon rainforest, it would still allow big agriculture companies like Cargill to continue to drive large-scale deforestation right next door in Brazil’s Cerrado savanna and Pantanal wetlands and export the products of that destruction to Europe.”
- The views expressed are those of the author, not necessarily Mongabay.

Fires bear down on Brazil park that’s home to jaguars, maned wolves
- Thousands of fires caused by humans in Brazil’s Cerrado savanna region continue to spread, with several fires around and inside Chapada dos Veadeiros National Park, a UNESCO World Heritage Site.
- The park is home to dozens of rare and threatened species as well as the source of many important rivers and waterways; experts warn the intensity of the fires could permanently damage the natural vegetation.
- The fires don’t come as a surprise to many scientists who had predicted earlier this year that ongoing drought, rising rates of deforestation, and lack of enforcement would build up to a severe fire season.
- Every single month this year has seen above-average levels of fire in the Cerrado, with more than 36% of all fires in Brazil this year concentrated in this biome, even though it only covers just over 20% of Brazil’s land mass.

‘On the map’: App shines light on 5,000 ‘invisible’ families in Brazil’s Cerrado and beyond
- A new report shows the results of an application that has mapped out more than 5,000 families in 76 communities from 23 Brazilian states, whose territories amount to 350,000 hectares (865,000 acres) that, until now, have gone unrecognized on official government maps.
- The digital mapping platform, called Tô No Mapa (“I am on the map” in Portuguese), allows traditional communities to demarcate their lands and list significant points of interest and conflict.
- The app was developed by the Brazilian civil society organization Institute for Society, Population and Nature (ISPN), the Amazon Environmental Research Institute (IPAM) and several other Brazilian NGOs working with traditional communities.
- Traditional peoples and communities play a vital role in conserving biodiversity, and guaranteeing their legal rights to land and territory is increasingly being recognized as a key conservation necessity, according to a wide range of studies and reports.
