Seeing the trees but not the forest (commentary)
(03/20/2015) Understanding forest dynamics is necessary for the sound management of forests, for both production and conservation. This includes an understanding of the extent of forest area, information about what the forest contains and how the forest resource is managed. Forest monitoring provides this information.
Endangered forests shrink as demand for soy rises
(03/10/2015) As battles over labeling genetically modified foods or displaying calorific breakdowns per serving rage on, it appears that a possibly more significant battle is in its infancy - where do all the ingredients on the package actually come from?
Brazil's soy moratorium dramatically reduced Amazon deforestation
(01/23/2015) The moratorium on forest conversion established by Brazilian soy giants in 2006 dramatically reduce deforestation for soy expansion in the Amazon, and have been more effective in cutting forest destruction than the government's land use policy in the region, finds a study published today in the journal Science.
China and Europe's outsourcing of soy production impacts the Amazon
(08/14/2014) Soy consumption in China and Europe is having significant ecological impacts in the Brazilian state of Mato Grosso, finds a study published in Environmental Research Letters.
Brazil could meet all its food demand by 2040 without cutting down another tree
(07/24/2014) Better utilization of its vast areas of pasturelands could enable Brazil to dramatically boost agricultural production without the need to clear another hectare of Amazon rainforest, cerrado, or Atlantic forest, argues a new study published in the journal Global Environmental Change.
Good intentions, collateral damage: forest conservation may be hurting grasslands
(07/10/2014) Trees absorb CO2 and trap carbon molecules, and countless are lost as forests are felled around the world. So why not plant as many as we can? A recent paper suggests otherwise; the planting of more trees through international reforestation schemes may actually be harming tropical grasslands, which harbor endemic species and offer unique ecosystem services.
Brazil should convert pasture, not cerrado for biofuel crops
(06/25/2014) If Brazil wants to respect its commitment to reducing greenhouse gas emissions it should target low productivity cattle pasture rather than native cerrado for biofuel crops like sugar cane, argues a new paper published in Nature Climate Change.
Intensifying cattle production in Brazil could cut global deforestation emissions 25%, says study
(04/28/2014) Brazil could reduce more than a quarter of emissions linked to deforestation worldwide by intensifying cattle production in the Amazon, argues a new study published in the journal Proceedings of the National Academy of Sciences.
Brazil's new Forest Code a mixed bag for native ecosystems
(04/24/2014) The revised Forest Code passed into law by Brazil in 2012 could authorize conversion of 400,000 square miles of native grassland for industrial agriculture, while granting amnesty for deforesters in the Amazon rainforest, argues a policy piece published this week in the journal Science.
Is Brazil's epic drought a taste of the future?
(02/25/2014) With more than 140 cities implementing water rationing, analysts warning of collapsing soy and coffee exports, and reservoirs and rivers running precipitously low, talk about the World Cup in some parts of Brazil has been sidelined by concerns about an epic drought affecting the country's agricultural heartland.
Brazil could boost agriculture without destroying forests
(12/03/2013) Brazil could substantially boost its agricultural output while increasing protection of its native ecosystems, finds a new analysis published by the Climate Policy Initiative (CPI), an international think tank.
Scientists discover new cat species roaming Brazil
(11/27/2013) As a family, cats are some of the most well-studied animals on Earth, but that doesn't mean these adept carnivores don't continue to surprise us. Scientists have announced today the stunning discovery of a new species of cat, long-confused with another. Looking at the molecular data of small cats in Brazil, researchers found that the tigrina—also known as the oncilla in Central America—is actually two separate species. The new species has been dubbed Leopardus guttulus and is found in the Atlantic Forest of southern Brazil, while the other Leopardus tigrinus is found in the cerrado and Caatinga ecosystems in northeastern Brazil.
New bat species discovered in Brazil leaves another at risk
(11/15/2013) A team of researchers has discovered a new species of bat in Brazil, which has put a previously known species, Bokermann's nectar bat (Lonchophylla bokermanni), at risk of extinction. Long thought to comprise one species, the bat populations of the Atlantic Forest and the Cerrado – the tropical savannah of Brazil's interior - are in fact distinct from one another, according to a new study in Zootaxa. Scientists now say the Atlantic Forest's population represents a newly described species, which they have dubbed Peracchi's nectar bat (Lonchophylla peracchii).
Little NGO takes on goliath task: conserving the vanishing ecosystems of Paraguay
(08/12/2013) Landlocked in the navel of South America, the forests, wetlands and savannahs of Paraguay boast rich biodiversity and endemic species, yet the unique landscapes of Paraguay also face increasing threats, primarily from agricultural expansion. Controlled burns and clear cutting have become common practice as wildlands are converted for soy and cattle production. In some areas this land conversion is rapid: the Paraguayan Chaco, for instance, is being lost at a rate of 10% per year. One organization is working to reverse this trend. Para La Tierra (PLT) is a small NGO dedicated to the conservation of threatened habitats in Paraguay. Located on the Reserva Natural Laguna Blanca, in-between two of South America's most threatened habitats: the Atlantic Forest and the vast topical savannah known as the cerrado, PLT is in a unique position to champion conservation.
Sugarcane production impacting local climate in Brazil
(05/01/2013) Intensification of Brazil's sugarcane industry in response to rising demand for sugar-based ethanol could have impacts on the regional climate reports a new study by researchers from Arizona State University, Stanford University and the Carnegie Institution for Science. Following the conversion of cerrado grasslands into sugarcane in Brazil, a recent study in Geophysical Research Letters found local cooling that approached 1 degree Celsius during the growing season and maximum local warming near 1 degree Celsius post-harvest.
Burned rainforest vulnerable to grass invasion
(04/24/2013) Rainforests that have been affected by even low-intensity fires are far more vulnerable to invasion by grasses, finds a new study published in special issue of the journal Philosophical Transactions of the Royal Society B. The findings are significant because they suggest that burned forests may be more susceptible to subsequent fires which may burn more intensely due to increased fuel loads.
Brazil launches forest trading system
(12/19/2012) Brazil has launched a new platform that enables farmers and ranchers who have cleared forest beyond the legal minimum to come into compliance by purchasing forest 'quotas' from landowners who have more than the mandated level of forest cover, reports the Associated Press. The system could spur increased compliance with the country's Forest Code, according to some experts.
Happy Halloween: nine new species of tree-climbing tarantula discovered
(10/31/2012) If you suffer from acute arachnophobia, this is the perfect Halloween discovery for you: a spider expert has discovered nine new species of arboreal (tree-dwelling) tarantulas in the Brazil. Although tarantula diversity is highest in the Amazon rainforest, the new species are all found in lesser-known Brazilian ecosystems like the Atlantic Forest, of which less than 7 percent remains, and the cerrado, a massive savannah that is being rapidly lost to agriculture and cattle ranching.
After seven year search, scientists film cryptic predator in Minas Gerais
(10/25/2012) South America's rare and little-known bush dog (Speothos venaticus) looks like a miniature dachshund who went bad: leaner, meaner, and not one to cuddle on your lap, the bush dog is found in 11 South American countries, but scientists believe it's rare in all of its habitats, which include the Amazon, the Pantanal wetlands, and the cerrado savannah. Given its scarcity, little is known about its wanderings.
Buffer zones key to survival of maned wolf
(09/17/2012) Known for its abnormally long lanky legs, its reddish-orange coat, and its omnivorous diet, the maned wolf (Chrysocyon brachyurus) is one of the more beautiful and bizarre predators of South America. However its stronghold, the Brazilian Cerrado, is vanishing rapidly to industrialized agriculture and urban development. Now, a new study in mongabay.com's open access journal Tropical Conservation Science reveals the key role of buffer zones and unprotected areas in keeping the maned wolf from extinction in the Cerrado savannah, where only 2 percent of the ecosystem is under protection.
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
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. Brazil's Environment Minister, Carlos Minc, has said that carbon emissions from the destruction of the cerrado are equal to those from the destruction of the Amazon.
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.
The cerrado is tropical savannah characterized by the annual average temperature of 68 degrees Fahrenheit (20 degrees Celsisu) 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.
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:
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.
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.
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.
