Humans drove rainforest into savannah in ancient Africa

2012-02-09T19:18:00Z

Three thousand years ago (around 1000 BCE) several large sections of the Congo rainforest in central Africa suddenly vanished and became savannah. Scientists have long believed the loss of the forest was due to changes in the climate, however a new study in Science implicates an additional culprit: humans. The study argues that a migration of farmers into the region led to rapid land-use changes from agriculture and iron smelting, eventually causing the collapse of rainforest in places and a rise of grasslands. The study has implications for today as scientists warn that the potent combination of deforestation and climate change could flip parts of the Amazon rainforest as well into savannah.

Majority of protected tropical forests "empty" due to hunting

2012-02-08T18:11:00Z

Protected areas in the world's tropical rainforests are absolutely essential, but one cannot simply set up a new refuge and believe the work is done, according to a new paper in Bioscience. Unsustainable hunting and poaching is decimating tropical forest species in the Amazon, the Congo, Southeast Asia, and Oceana, leaving behind "empty forests," places largely devoid of any mammal, bird, or reptile over a few pounds. The loss of such species impacts the whole ecosystems, as plants lose seed dispersers and the food chain is unraveled.

New rainforest and indigenous reserve established in Peru

2012-02-07T17:39:00Z

On February 4th, the Peruvian government and a small indigenous group created a new Amazon reserve, dubbed the Maijuna Reserve. Located in northeastern Peru, the 390,000 hectare (970,000 acres) reserve is larger than California's Yosemite National Park and over three times the size of Hong Kong.

Guyanese tribe maps Connecticut-sized rainforest for land rights

2012-02-07T16:20:00Z

In a bid to gain legal recognition of their land, the indigenous Wapichan people have digitally mapped their customary rainforest land in Guyana over the past ten years. Covering 1.4 million hectares, about the size of Connecticut, the rainforest would be split between sustainable-use regions, sacred areas, and wildlife conservation according to a plan by the Wapichan tribe that will be released today. The plan says the tribe would preserve the forest from extractive industries.

Fungus from the Amazon devours plastic

2012-02-02T20:05:00Z

Students from Yale University have made the amazing discovery of a species of fungus that devours one of the world's most durable, and therefore environmentally troublesome, plastics: polyurethane. The new species of fungus, Pestalotiopsis microspora, is even able to consume polyurethane in zero-oxygen (anaerobic) conditions, which would be important in eating plastics in the deep dark layers of landfills where little sunlight, water, or oxygen is found.

Photo of the day: super-abundance of life found in Amazon park

2012-02-02T18:22:00Z

Surveying a little-explored park in the Peruvian Amazon has paid off in dividends: researchers with the Wildlife Conservation Society (WCS) have cataloged 365 species that had not yet been recorded in Bahuaja Sonene National Park. The never-before recorded species included two bats, thirty birds, and over two hundred butterflies and moths.

Group releases close-up photos of 'uncontacted' tribe in Peru

2012-02-01T20:38:00Z

New photos provide visual evidence of just how close the long-isolated tribe of Mashco-Piro people in the Amazon rainforest are to being contacted by the outside world—a perilous moment for tribes highly susceptible to disease and likely to defend their people and territory with weapons. According to indigenous rights NGO Survival International, the Maschco-Piro tribe has been seen more frequently outside of their forest home in Manu National Park in recent years. Some experts blame illegal logging in the park and helicopters used in oil and gas projects for the sightings.

New meteorological theory argues that the world's forests are rainmakers

2012-02-01T17:36:00Z

New, radical theories in science often take time to be accepted, especially those that directly challenge longstanding ideas, contemporary policy or cultural norms. The fact that the Earth revolves around the sun, and not vice-versa, took centuries to gain widespread scientific and public acceptance. While Darwin's theory of evolution was quickly grasped by biologists, portions of the public today, especially in places like the U.S., still disbelieve. Currently, the near total consensus by climatologists that human activities are warming the Earth continues to be challenged by outsiders. Whether or not the biotic pump theory will one day fall into this grouping remains to be seen. First published in 2007 by two Russian physicists, Victor Gorshkov and Anastassia Makarieva, the still little-known biotic pump theory postulates that forests are the driving force behind precipitation over land masses.

Saving the world's biggest river otter

2012-01-30T20:12:00Z

Charismatic, vocal, unpredictable, domestic, and playful are all adjectives that aptly describe the giant river otter (Pteronura brasiliensis), one of the Amazon's most spectacular big mammals. As its name suggest, this otter is the longest member of the weasel family: from tip of the nose to tail's end the otter can measure 6 feet (1.8 meters) long. Living in closely-knit family groups, sporting a complex range of behavior, and displaying almost human-like capricious moods, the giant river otter has captured a number of researchers and conservationists' hearts, including Dutch conservationist Jessica Groenendijk.

Big trees, like the old-growth forests they inhabit, are declining globally

2012-01-26T23:01:00Z

Already on the decline worldwide, big trees face a dire future due to habitat fragmentation, selective harvesting by loggers, exotic invaders, and the effects of climate change, warns an article published this week in New Scientist magazine. Reviewing research from forests around the world, William F. Laurance, an ecologist at James Cook University in Cairns, Australia, provides evidence of decline among the world's 'biggest and most magnificent' trees and details the range of threats they face. He says their demise will have substantial impacts on biodiversity and forest ecology, while worsening climate change.

Photos: 46 new species found in little-explored Amazonian nation

2012-01-25T00:02:00Z

South America's tiniest independent nation still hides a number of big surprises: a three week survey to the sourthern rainforests of Suriname found 46 potentially new species and recorded nearly 1,300 species in all. Undertaken by Conservation International's (CI) Rapid Assessment Program (RAP) the survey found new species of freshwater fish, insects, and a new frog dubbed the "cowboy frog" for the spur on its heel. While Suriname may be small, much of its forest, in the Guyana Shield region of the Amazon, remains intact and pristine. The Food and Agriculture Organization (FAO) estimates that 91 percent of Suriname is covered in primary forests, however this data has not been updated in over two decades.

Brazil begins preliminary damming of Xingu River as protests continue

2012-01-19T19:58:00Z

Damming of the Xingu River has begun in Brazil to make way for the eventual construction of the hugely controversial, Belo Monte dam. The Norte Energia (NESA) consortium has begun building coffer dams across the Xingu, which will dry out parts of the river before permanent damming, reports the NGO International Rivers. Indigenous tribes, who have long opposed the dam plans on their ancestral river, conducted a peaceful protest that interrupted construction for a couple hours.

Geology has split the Amazon into two distinct forests

2012-01-19T17:38:00Z

The common view of the Amazon is that it is one massive, unbroken forest. This impression is given by maps which tend to mark the Amazon by a large glob of green or even by its single name which doesn't account for regional changes. Of course, scientists have long recognized different ecosystems in the Amazon, most especially related to climate. But a new study in the Journal of Biogeography has uncovered two distinct forest ecosystems, sharply divided, caused by million of years of geologic forces.

Deforestation, climate change threaten the ecological resilience of the Amazon rainforest

2012-01-19T02:02:00Z

Colonization program remains important driver of deforestation in Brazil

2012-01-10T13:58:00Z

Government-subsidized colonization of the Amazon rainforest remains an important driver of forest loss in Brazil, but has mixed economic value, argues a paper published in Biological Conservation.

As Amazon deforestation falls, food production rises

2012-01-09T22:38:00Z

A sharp drop in deforestation has been accompanied by an increase in food production in the Brazilian state of Mato Grosso, reports a new study published in the journal Proceedings of the National Academy of Science. The research argues that policy interventions, combined with pressure from environmental groups, have encouraged agricultural expansion in already-deforested areas, rather than driving new forest clearing.

Ecuador makes $116 million to not drill for oil in Amazon

2012-01-02T17:39:00Z

A possibly ground-breaking idea has been kept on life support after Ecuador revealed its Yasuni-ITT Initiative had raked in $116 million before the end of the year, breaking the $100 million mark that Ecuador said it needed to keep the program alive. Ecuador is proposing to not drill for an estimated 850 million barrels of oil in the Ishpingo-Tambococha-Tiputinin (ITT) blocs of Yasuni National Park if the international community pledges $3.6 billion to a United Nations Development Fund (UNDF), or about half of what the oil is currently worth. The Yasuni-ITT Initiative would preserve arguably the most biodiverse region on Earth from oil exploitation, safeguard indigenous populations, and keep an estimated 410 million tons of CO2 out of the atmosphere. However, the initiative is not without its detractors, some arguing the program is little more than blackmail; meanwhile proponents say it could prove an effective way to combat climate change, deforestation, and mass extinction.

The year in review for rainforests

2011-12-28T18:08:00Z

2011 was designated as "Year of the Forests" by the United Nations. While there was relatively little progress on intergovernmental forest protection programs during the year, a lot happened elsewhere. Below is a look at some of the biggest tropical forest-related news stories for 2011. We at mongabay readily acknowledge there were a number of important temperate and boreal forest developments, including Britain's decision not to privatize its forests and the severe drought in Texas, but this article will cover only tropical forest news.

Peru's Cocha Cashu biological station changes management

2011-12-08T18:30:00Z

The San Diego Zoo Global Wildlife Conservancy is taking over management of the productive Cocha Cashu field station in Manu National Park, Peru. To date, nearly 600 scientific papers have come out of research conducted at the station, making it among the five most productive research stations in the Amazon and Andes. Located in a part of the Amazon rainforest that has seen little human impact, the station was founded in 1969, four years before Manu National Park was gazetted.

Brazil passes controversial Forest Code reform environmentalists say will be 'a disaster' for the Amazon

2011-12-06T23:59:00Z

The Brazilian Senate tonight passed controversial legislation that will reform the country's 46-year-old Forest Code, which limits how much forest can be cleared on private lands. Environmentalists are calling the move "a disaster" that will reverse Brazil's recent progress in slowing deforestation in the world's largest rainforests.

Amazon rainforest loss in Brazil drops to lowest ever reported

2011-12-05T23:59:00Z

Deforestation and forest degradation slows in Brazil's Amazon since August

2011-12-02T23:17:00Z

Deforestation and forest degradation are down moderately from August through October 2011 relative to the same period a year ago, reports a satellite-based assessment released today by Imazon. Imazon's near-real time system found that 512 sq km of rainforest were cleared between Aug 2011 and Oct 2011, the first three months of the deforestation calendar year, which runs from August 1 through July 31. The figure represents a 4 percent decline from the 533 sq km cleared in 2010

Brazil's Forest Code vote delayed

2011-11-30T18:27:00Z

The Brazilian Senate's much-anticipated vote over proposed changes to the country's Forest Code will take place Tuesday December 6, rather than today. The delay will give lawmakers more time to understand pending revisions to the code, which limits the amount of land private landowners can clear and restricts development in ecologically sensitive areas.

Carbon piracy, lack of recognition of indigenous rights undermining REDD in Peru, alleges report

2011-11-30T05:51:00Z

Lack of meaningful consultation with indigenous communities over forest carbon projects is causing social conflict and undermining efforts to responsibly reduce emissions from deforestation and forest degradation in Peru under the REDD mechanism, argues a new report released during international climate talks in Durban.

Ecotourism isn't bad for wildlife in the Amazon

2011-11-23T18:28:00Z

Ecotourism doesn't hurt biodiversity, and in some cases may even safeguard vulnerable areas, concludes a new study from the Amazon in Mammalian Biology. Surveying large mammals in an ecotourism area in Manu National Biosphere, the researchers found that ecotourists had no effect on the animals. However, the researchers warn that not all ecotourism is the same, and some types may, in fact, hurt the very animals tourists come to see.

Peru's real test is a 200km pipeline

2011-10-27T17:32:00Z

One of Ollanta Humala's most striking achievements since becoming Peru's president three months ago is new legislation guaranteeing indigenous people the right to be consulted about and in agreement with any project that affects them. Leading indigenous organization AIDESEP, usually so critical of the government, cautiously welcomed the move, while Survival International called it 'a significant step away from the policies of former Peruvian president Alan Garcia, who vetoed a similar bill.'

Breakthrough technology enables 3D mapping of rainforests, tree by tree

2011-10-24T23:33:00Z

High above the Amazon rainforest in Peru, a team of scientists and technicians is conducting an ambitious experiment: a biological survey of a never-before-explored tract of remote and inaccessible cloud forest. They are doing so using an advanced system that enables them to map the three-dimensional physical structure of the forest as well as its chemical and optical properties. The scientists hope to determine not only what species may lie below but also how the ecosystem is responding to last year's drought—the worst ever recorded in the Amazon—as well as help Peru develop a better mechanism for monitoring deforestation and degradation.

Bolivian road project through Amazon reserve canceled

2011-10-23T18:06:00Z

Following a violent crackdown on protestors which deeply embarrassed the Bolivian government, president Evo Morales has thrown-out plans to build a road through an indigenous reserve, reports the BBC. Protestors marched 310 miles (498 kilometers) from the Amazon to La Paz to show their opposition to the road, saying that the project would destroy vast areas of biodiverse rainforest and open up their land to illegal settlers.

Isolated indigenous people and tourists collide in Peru park

2011-10-19T17:57:00Z

New video released by the Peruvian government shows a potentially disastrous encounter between tourists and indigenous people long isolated from the outside world. In a motor boat tourists follow a group of Mashco-Piro people walking along the shores of the Manu River in Manu National Park. At one point one of the tribal members prepares to fire at the boat with an arrow. But danger doesn't only come from the possibility of a violent clash: uncontacted indigenous people, those who have chosen isolation from the world, are incredibly susceptible to disease.

Belo Monte dam license 'illegal' rules Brazilian federal judge

High gold price triggers rainforest devastation in Peru

2011-10-11T12:54:00Z

As the price of gold inches upward on international markets, a dead zone is spreading across the southern Peruvian rain forest. Tourists flying to Manu or Tambopata, the crown jewels of the country’s Amazonian parks, get a jarring view of a muddy, cratered moonscape ... and then another ... and another in what the country boasts is its capital of biodiversity. While alluvial gold mining in the Amazon is probably older than the Incas, miners using motorized suction equipment, huge floating dredges and backhoes are plowing through the landscape on an unprecedented scale, leaving treeless scars visible from outer space. Sources close to the Peruvian Environment Ministry say the government is considering declaring an environmental emergency in the region, but emergency measures passed two years ago were not enough to contain the destruction, and some observers doubt that a new decree would have any more impact.

Brazil: Amazon deforestation higher than initially stated

2010 Amazon drought released more carbon than India's annual emissions

2011-10-09T14:34:00Z

The 2010 drought that affected much of the Amazon rainforest triggered the release of nearly 500 million tons of carbon (1.8 billion tons of carbon dioxide) into the atmosphere, or more than the total emissions from deforestation in the region over the period, estimates a new study published in the journal Environmental Research Letters.

Judge: work must halt on monster dam, Belo Monte

2011-09-29T18:51:00Z

The decades-long fight over Brazilian megadam, the Belo Monte, has taken another U-turn after a judge ordered work to stop immediately since the dam would devastate vital fishing grounds for local people. In June the Brazilian government gave a go-ahead to the $11-17 billion dam, despite large-scale opposition from indigenous groups along the Xingu River and international outcry, including a petition signed by 600,000 people.

Repeated burning undercuts Amazon rainforest recovery

2011-09-26T20:21:00Z

The Amazon rainforest can recover fromlogging, but has a far more difficult time returning after repeated burning, reports a new study in mongabay.com's open-access journal Tropical Conservation Science. In areas where the Amazon had been turned to pasture and was subject to repeated burning, Visima trees become the dominant tree inhibiting the return of a biodiverse forest. The key to the sudden domination of Visima trees, according to the study, is that these species re-sprout readily following fires; a capacity most other Amazonian trees lack.
