(11/30/2010) While governments continue to stall on action to cut greenhouse gas emissions worldwide, global corporations are promising big changes to tackle their responsibilities. The Board of Consumer Goods Forum (BCGF) has approved a resolution to achieve net zero deforestation by 2020 in products such as palm oil, soy, beef, and paper. Announced yesterday at the UN Climate Summit in Cancun, the BCGF has stated the goal will be met both by individual actions within companies and collective action, including partnerships with NGOs, development banks, and governments. With such giants as Walmart, Unilever, Carrefour, and General Mills, BCGF is made up of four hundred global consumer goods manufacturers and retailers totaling over $2.8 trillion in revenue.
Slight rise in mangrove forests in Eastern India
(11/29/2010) While mangrove forests are vanishing around the world, the Indian Ministry of Environment and Forests is reporting a slight uptick of mangrove forests along the nation's eastern coast. According to a report, mangroves expanded from 4,581 square kilometers in 2005 to 4,639 square kilometers in 2007, an increase of 58 square kilometers.
Good stewards of forests at home outsource deforestation abroad
(11/24/2010) As more nations adopt better laws and policies to save and restore forests at home, they may, in fact, be outsourcing deforestation to other parts of the world, according to a new study in the Proceedings of the National Academy of Sciences (PNAS). Looking at six developing nations where forests are recovering—instead of receding—the study found only one of them did not outsource deforestation to meet local demand for wood-products and food, a process known as 'leakage'.
Oil, indigenous people, and Ecuador's big idea
(11/23/2010) Ecuador's big idea—potentially Earth-rattling—goes something like this: the international community pays the small South American nation not to drill for nearly a billion barrels of oil in a massive block of Yasuni National Park. While Ecuador receives hundred of millions in an UN-backed fund, what does the international community receive? Arguably the world's most biodiverse rainforest is saved from oil extraction, two indigenous tribes' requests to be left uncontacted are respected, and some 400 million metric tons of CO2 is not emitted from burning the oil. In other words, the international community is being asked to put money where its mouth is on climate change, indigenous rights, and biodiversity loss. David Romo Vallejo, professor at the University of San Francisco Quito and co-director of Tiputini research station in Yasuni, recently told mongabay.com in an interview that this is "the best proposal so far made to ensure the protection of this incredible site."
New population of Critically Endangered monkey discovered
(11/22/2010) Classified as Critically Endangered by the IUCN Red List, listed among the Top 25 Most Endangered primates in the world, and rated number 71 on the EDGE's list of world's most endangered and unique mammals, the yellow-tailed woolly monkey needed some good news—and this week it got it. The conservation organization, Neotropical Primate Conservation (NPC), has announced the discovery of an unknown population of the yellow-tailed woolly monkey (Oreonax flavicauda), buttressing hopes that the species will survive in the long-term.
Photos: wild, weird, and rare mammals storm the conservation world
(11/21/2010) What do the New Zealand greater short-tailed bat, the black-and-white ruffed lemur, and the numbat have in common? They are all new members of the Zoological Society of London's EDGE top 100 most endangered and unique mammals list. Arguably the most innovative conservation program in the world, EDGE decides which species to focus conservation efforts on not based on popularity or fund-raising potential, but on hard data, only working with species that are considered the most endangered and evolutionarily distinct.
50 NGOS tell big oil to get out of uncontacted natives' territory
(11/21/2010) A letter signed by over 50 NGOs is calling on three big oil companies—Perenco, Repsol-YPF, and ConocoPhillips—to withdraw from Peruvian territory inhabited by uncontacted indigenous tribes. The letter states that the oil companies' presence in the area threatens the uncontacted tribe with diseases, for which they have little immunity, and puts the lives of oil company workers in jeopardy, since past encounters have ended in violence.
Bad books: US paper products are breaking the law and devastating rainforests
(11/18/2010) Everyone knows books are made of paper, but few think of where that paper comes from. However, two new reports may change that. Both the Rainforest Action Network (RAN) and the World Resources Institute (WRI) have found that some paper used in books, including popular children's books, is linked to forest devastation in Indonesian, even targeting endangered trees that have been harvested illegally.
Reforestation effort launched in Borneo with nearly-extinct rhinos in mind
(11/18/2010) The Rhino and Forest Fund (RFF) has partnered with the Forestry Department of Sabah in northern Borneo to launch a long-term reforestation project to aid Malaysia's threatened species with particular emphasis on the Bornean rhino (Dicerorhinus sumatrensis harrissoni), one of the world's most imperiled big mammals. The reforestation project will be occurring in and adjacent to Tabin Wildlife Reserve, which is surrounded on all sides by oil palm plantations.
Photographer discovers new species of meat-eating plant in Cambodia
(11/16/2010) British photographer Jeremy Holdren recently discovered a new species of carnivorous pitcher plant in Cambodia's Cardamom Mountains during a survey with Fauna & Flora International (FFI).
Chaco biodiversity expedition suspended
(11/15/2010) A joint expedition by the Natural History Museum (NHM), London and the Natural History Museum, Asuncion to the dwindling dry forest of the Gran Chaco in Paraguay to record biodiversity, and hopefully uncover 'hundreds' of new species, has been suspended by the Paraguayan government. The suspension comes after a local organization voiced concern that the expedition would threaten uncontacted member of the Ayoreo tribe in the forest.
Formal petition filed against Belo Monte dam
(11/11/2010) The struggle against Brazil's Belo Monte dam on the Xingu River continues as today indigenous groups sent a formal petition to the Inter-American Commission on Human Rights (IACHR) to suspend the dam's construction, stating the dam violates human rights. The dam, which has been contentious in Brazil for decades, would flood 500 square miles of rainforest, lead to the removal of at least 12,000 people in the region, and upturn the lives of 45,000 indigenous people who depend on the Xingu River for survival.
Chaco expedition working to "minimize the risk" of running into uncontacted natives
(11/11/2010) A joint expedition by the Natural History Museum (NHM), London and the Natural History Museum, Asuncion to study the biodiversity of the dwindling dry forests of Chaco in Paraguay have responded to recent concerns that they risk encountering uncontacted natives, which could potentially threaten the natives' lives as well as their own.
Amazon biodiversity older than believed
(11/11/2010) A new study in Science has found that the incredible biodiversity of the Amazon rainforest goes back much further than expected, perhaps upending old ideas about how the Amazon basin became arguably the world's most biodiverse ecosystem. According to the study, the origin of rich biodiversity in the Amazon likely goes back more than 20 million years when the Andean mountains were rising.
Rainforests thrived in warmer conditions in the past, yet study requires "caution"
(11/11/2010) A new study in Science is likely to reopen the contentious debate about the impact of climate change on tropical rainforests. Scientific modeling of future climate conditions in tropical rainforests, such as the Amazon, has shown that climate change—combined with deforestation and fire—could create a tipping point whereby a significant portion of the Amazon could turnover to savannah, pushing untold species to extinction and undercutting the many ecosystem services provided by tropical rainforests. Yet, a new study headed by Carlos Jaramillo, staff scientist at the Smithsonian Tropical Research Institute (STRI), has found a tropical forest ecosystem thriving in much warmer conditions than today.
Photos: surprises discovered in tiny forest fragment surrounded by palm oil
(11/10/2010) Researchers have uncovered an astounding number of species in a tiny protected forest fragment surrounded on all side by palm oil plantations in the Indonesian island of Sumatra. Researchers with the Zoological Society of London (ZSL), Queen Mary, University of London and the Durrell Institute of Conservation and Ecology (DICE – University of Kent) recorded sun bear (Helarctos malayanus), Malayan tapir (Tapirus indicus), the banded langur (Presbytis femoralis), and agile gibbons (Hylobates agilis), but most notable, was the first record ever of the Ridley's leaf-nosed bat (Hipposideros ridleyi) in Sumatra. The discoveries highlight the importance of preserving even small forest fragments surrounded by agriculture.
Eight new plants discovered in Bolivia
(11/07/2010) Researchers have described eight new species of plant from in and near Madidi National Park in the Bolivian Andes. Described in the journal Novon by botanists with the Missouri Botanical Garden and the National Herbaium in Laz Paz, Bolivia, seven of the eight plants were found as apart of the Proyecto Madidi (Project Madidi), a ten year effort to describe the plant species of three inter-connecting protected areas in Bolivia—Madidi National Park, Pilón Lajas Biosphere Reserve and Communal Lands, and Apolobamba Integrated Management Natural Area.
Tropical agriculture "double-whammy": high emissions, low yields
(11/02/2010) Food produced in the tropics comes with high carbon emissions and low crop yields, according to a new study in the Proceedings of the National Academy of Sciences (PNAS). In the most comprehensive and detailed study to date looking at carbon emissions versus crop yields, researchers found that food produced in the tropics releases almost double the amount of carbon while producing half the yield as food produced in temperate regions. In other words, temperate food production is three times more efficient in terms of yield and carbon emissions.
Undergrads in the Amazon: American students witness beauty and crisis in Yasuni National Park, Ecuador
(10/28/2010) Although most Americans have likely seen photos and videos of the world's largest rainforest, the Amazon, they will probably never see it face-to-face. For many, the Amazon seems incredibly remote: it is a dim, mysterious place, a jungle surfeit in adventure and beauty—but not a place to take a family vacation or spend a honeymoon. This means that the destruction of the Amazon, like the rainforest itself, also appears distant when seen from Oregon or North Carolina or Pennsylvania. Oil spills in Ecuador, cattle ranching in Brazil, hydroelectric dams in Peru: these issues are low, if not non-existent, for most Americans. But a visit to the Amazon changes all that. This was recently confirmed to me when I traveled with American college students during a trip to far-flung Yasuni National Park in Ecuador. As a part of a study abroad program with the University of San Francisco in Quito and the Galapagos Academic Institute for the Arts and Sciences (GAIAS), these students spend a semester studying ecology and environmental issues in Ecuador, including a first-time visit to the Amazon rainforest at Tiputini Biodiversity Station in Yasuni—and our trips just happened to overlap.
Norway calls for other nations to step up in fight against deforestation in Indonesia
(10/27/2010) On Monday, Norway's Environment Minister called for the US, Japan, and the EU to open their pocket books to support Indonesia's drive to stop deforestation, according to Reuters. Norway has pledged $1 billion to Indonesia in an effort to stop rampant deforestation mostly due to industrial logging and the establishment of commercial plantations for palm oil and paper production.
Picture: new monkey discovered in Myanmar
(10/26/2010) Hunters' reports have led scientists to discover a new species of monkey in the northern forests of Myanmar. Discovered by biologists from the Myanmar Biodiversity and Nature Conservation Association with support from primatologists with Fauna & Flora International (FFI) and the People Resources and Biodiversity Foundation, the strange looking primate is a member of the snub-nosed monkey family, adding a fifth member to this unmistakably odd-looking group of Asian primates. However, the species survives in only a small single population, threatened by Chinese logging and hunting.
Life shocker: new species discovered every three days in the Amazon
(10/26/2010) A new report by the World Wide Fund for Nature (WWF) confirms the Amazon rainforest, even as it is shrinking due to deforestation, remains among the world's most surprising places. According to the report, Amazon Alive, over the past decade (1999-2009) researchers have found 1,200 new species in the Amazon: one new species for every three days. Not surprisingly invertebrates, including insects, made up the bulk of new discoveries. But no type of species was left out: from 1999-2009 researchers discovered 637 new plants, 357 fish, 216 amphibians, 55 reptiles, 39 mammals, and 16 new birds. In new discoveries over the past decade, the Amazon has beaten out a number of high-biodiversity contenders including Borneo, the Eastern Himalayas, and the Congo rainforest.
Amazon suffers worst drought in decades
(10/24/2010) The worst drought since 1963 has created a regional disaster in the Brazilian Amazon. Severely low water levels have isolated communities dependent on river transport. Given a worsening situation, Brazil announced on Friday an emergency package of $13.5 million for water purification, tents, and food airdrops.
Foreign corporations devastating Papua New Guinea rainforests
(10/21/2010) A letter in Nature from seven top scientists warns that Papua New Guinea's accessible forest will be lost or heavily logged in just ten to twenty years if swift action isn't taken. A potent mix of poor governance, corruption, and corporate disregard is leading to the rapid loss of Papua New Guinea's much-heralded rainforests, home to a vast array of species found no-where else in the world. "Papua New Guinea has some of the world's most biologically and culturally rich forests, and they’re vanishing before our eyes," author William Laurance of James Cook University in Cairns, Australia, said in a statement.
Environmentalists must recognize 'biases and delusions' to succeed
(10/18/2010) As nations from around the world meet at the Convention on Biological Diversity in Nagoya, Japan to discuss ways to stem the loss of biodiversity worldwide, two prominent researchers argue that conservationists need to consider paradigm shifts if biodiversity is to be preserved, especially in developing countries. Writing in the journal Biotropica, Douglas Sheil and Erik Meijaard argue that some of conservationists' most deeply held beliefs are actually hurting the cause.
The ultimate bike trip: the Amazon rainforest
(10/17/2010) Like all commercial roads through rainforests, the 5,300 kilometer long Rodovia Transamazonica (in English, the Trans-Amazonia), brought two things: people and environmental destruction. Opening once-remote areas of the Amazon to both legal and illegal development, farmers, loggers, and miners cut swathes into the forest now easily visible from satellite. But the road has also brought little prosperity: many who live there are far from infrastructure and eek out an impoverished existence in a harsh lonely wilderness. This is not a place even the most adventurous travelers go, yet Doug Gunzelmann not only traveled the entirety of the Transamazonica in 2009, he cycled it. A self-described adventurer, Gunzelmann chose to bike the Transamazonica as a way to test his endurance on a road which only a few before have completed. But Gunzelmann wasn't just out for adrenaline-rushes, he was also deeply interested in the environmental issues related to the Transamazonica. What he found was a story without villains, but only humans—and the Amazon itself—trying to survive in a complex, confusing world.
Video: camera trap catches bulldozer clearing Sumatran tiger habitat for palm oil
(10/14/2010) Seven days after footage of a Sumatran tiger (Panthera tigris sumatrae) was taken by a heat-trigger video camera trap, the camera captured a bulldozer clearing the Critically Endangered animal's habitat. Taken by the World Wildlife Fund—Indonesia (WWF), the video provides clear evidence of forest destruction for oil palm plantations in Bukit Batabuh Protected Forest, a protected area since 1994.
Satellites show fragmented rainforests significantly drier than intact forest
(10/13/2010) A new study in Biological Conservation has shown that edge forests and forest patches are more vulnerable to burning because they are drier than intact forests. Using eight years of satellite imagery over East Amazonia, the researchers found that desiccation (extreme dryness) penetrated anywhere from 1 to 3 kilometers into forests depending on the level of fragmentation.
Humanity consuming the Earth: by 2030 we'll need two planets
(10/13/2010) Too many people consuming too much is depleting the world's natural resources faster than they are replenished, imperiling not only the world's species but risking the well-being of human societies, according to a new massive study by the World Wildlife Fund (WWF), entitled the Living Planet Report. The report finds that humanity is currently consuming the equivalent of 1.5 planet Earths every year for its activities. This overconsumption has caused biodiversity—in this case, representative populations of vertebrate animals—to fall by 30 percent worldwide since 1970. The situation is more dire in tropical regions where terrestrial species' populations have fallen by 60 percent and freshwater species by 70 percent.
Can 'boutique capitalism' help protect the Amazon?
(10/11/2010) Most companies talk green, but few—almost none in fact—actually walk the walk. Sustainable design company, Ecostasy, not only walks the walk, but actually seeks out among the most challenging places to work: the imperiled Brazilian Amazon. Specializing in hand-crafted products by indigenous groups—such as jewelry, pots, and furniture—Ecostasy seeks to balance smart economics, environmental protection, and community development. Make no mistake, however, Ecostasy is not a non-profit, but a rare and refreshing example of a company truly dedicated to changing the world for the better. "In my mind, a virtuous company does not compromise ethical principles for economic interests. For me, being ethical is comprised of conducting oneself with honesty and responsibility to one’s constituencies (customers, employees, suppliers), society and the environment," Katherine Ponte, founder of Ecostasy, told mongabay.com in an interview.
The Nestlé example: how responsible companies could end deforestation
(10/06/2010) The NGO, The Forest Trust (TFT), made international headlines this year after food giant Nestlé chose them to monitor their sustainability efforts. Nestlé's move followed a Greenpeace campaign that blew-up into a blistering free-for-all on social media sites. For months Nestle was dogged online not just for sourcing palm oil connected to deforestation in Southeast Asia—the focus of Greenpeace's campaign—but for a litany of perceived social and environmental abuses and Nestlé's reactions, which veered from draconian to clumsy to stonily silent. The announcement on May 17th that Nestlé was bending to demands to rid its products of deforestation quickly quelled the storm. Behind the scenes, Nestlé and TFT had been meeting for a number of weeks before the partnership was made official. But can TFT ensure consumers that Nestlé is truly moving forward on cutting deforestation from all of its products?
Photos: 200 new species discovered in 60-day expedition in New Guinea
(10/06/2010) A 2009 expedition to Papua New Guinea proves once again that the island-nation is as diverse in life as it is in human cultures. It took researchers with Conservation International (CI) and the local Institute for Biological Research (IBR) just two months to uncover a startling 200 new species: averaging more than 3 a day in the remote Nakanai Mountains and Muller Range rising from the island of New Britain, a part of Papua New Guinea. Half of the new species were spiders, but the team also found two new mammals, nine new plants, two dozen frogs, and multitude of insects. Most surprising was the discovery of at least two species so unique that they are likely to be assigned their own genus.
Losing nature's medicine cabinet
(10/04/2010) In all the discussions of saving the world's biodiversity from extinction, one point is often and surprisingly forgotten: the importance of the world's species in providing humankind with a multitude of life-saving medicines so far, as well as the certainty that more vital medications are out there if only we save the unheralded animals and plants that contain cures unknown. Already, species have provided humankind everything from quinine to aspirin, from morphine to numerous cancer and HIV-fighting drugs. "As the ethnobotanist Dr. Mark Plotkin commented, the history of medicine can be written in terms of its reliance on and utilization of natural products," physician Christopher Herndon told mongabay.com. Herndon is co-author of a recent paper in the journal Biotropica, which calls for policy-makers and the public to recognize how biodiversity underpins not only ecosystems, but medicine.
Yasuni on film: could a documentary save the world's most biodiverse ecosystem?
(10/04/2010) How do you save one of the most biologically and culturally diverse places in the world if most people have never heard of it? If you want a big audience—you make a film. This is what wildlife-filmmaker Ryan Killackey is hoping to do with his new movie Yasuni Man. Killackey says the film will show-off the wonders of Yasuni National Park while highlighting the complexity of its biggest threat: the oil industry. "Conceptually, the film resembles a true-life cross between the documentary Crude and the blockbuster Avatar—except it's real and it's happening now," Killackey told mongabay.com.
Fighting poachers, going undercover, saving wildlife: all in a day's work for Arief Rubianto
(09/29/2010) Arief Rubianto, the head of an anti-poaching squad on the Indonesian island of Sumatra best describes his daily life in this way: "like mission impossible". Don't believe me? Rubianto has fought with illegal loggers, exchanged gunfire with poachers, survived four days without food in the jungle, and even gone undercover—posing as a buyer of illegal wildlife products—to infiltrate a poaching operation. While many conservationists work from offices—sometimes thousands of miles away from the area they are striving to protect—Rubianto works on the ground (in the jungle, in flood rains, on rock faces, on unpredictable seas, and at all hours of the day), often risking his own life to save the incredibly unique and highly imperiled wildlife of Sumatra.
Mass extinction fears widen: 22 percent of world's plants endangered
(09/28/2010) Scientific warnings that the world is in the midst of a mass extinction were bolstered today by the release of a new study that shows just over a fifth of the world's known plants are threatened with extinction—levels comparable to the Earth's mammals and greater than birds. Conducted by the Royal Botanic Gardens, Kew; the Natural History Museum, London; and the International Union for the Conservation of Nature (IUCN), the study is the first time researchers have outlined the full threat level to the world's plant species. In order to estimate overall threat levels, researchers created a Sampled Red List Index for Plants, analyzing 7,000 representative species, including both common and rare plants.
U.S. government bombs Guam with frozen mice to kill snakes
(09/28/2010) In a spectacularly creative effort to rid the island of Guam of an invasive species, the US Department of Agriculture is planning to 'bomb' the rainforests with dead frozen mice laced with acetaminophen. The mice-bombs are meant to target the brown tree snake, an invasive species which has ravaged local wildlife, and angered local residents, since arriving in the 1940s.
Discovery of new population boosts almost-extinct Colombian bird
(09/28/2010) The Baudo oropendola (Psarocolius cassini) has gone from less than a dozen known individuals to nearly a hundred due to the discovery of two new colonies in northwestern Colombia by local conservation group, Fundación ProAves. However, the new colonies are located in an unprotected area currently being impacted by deforestation. George Fenwick, president of American Bird Conservancy which focuses on bird conservation, said in a press release that his organization "is thrilled to have helped fund the research expedition that led to this stunning discovery of these two new colonies of this rare bird. Now we need to work with ProAves to conserve and protect them."
Ugandan forest being stripped for fuel wood
(09/27/2010) A new study in the open access journal of Tropical Conservation Science finds that the Kasagala forest reserve in central Uganda is losing important tree species and suffering from low diversity of species. Researchers believe that forest degradation for charcoal and firewood has put heavy pressure on this ecosystem.
The effect of forest regeneration strategies on beetles
(09/27/2010) As conservationists attempt to find the best way to re-establish forests in abandoned areas, a new study in the open-access journal Tropical Conservation Science compares the impacts on bess beetles of different method to regeneration forest. Bess beetles are important dead wood-recyclers in the forest. Looking at three different forests in the Colombian Andes—natural regeneration, monoculture reforestation, and an old-growth forest as a baseline—researchers found that old-growth and natural regeneration had the highest diversity of bess beetles, while old-growth sported the greatest abundance of beetles.
Financial crisis pummels wildlife and people in the Congo rainforest
(09/27/2010) Spreading over three central African nations—Cameroon, Central African Republic, and Republic of Congo—the Sangha tri-national landscape is home to a variety of actors: over 150,000 Bantu people and nearly 20,000 pygmies; endangered species including forest elephants and gorillas; and, not least, the Congo rainforest ecosystem itself, which here remains largely intact. Given its interplay of species-richness, primary rainforest, and people—many of whom are among the poorest in the world—the landscape became internationally important in 2002 when under the Congo Basin Forest Partnership (CBFP) conservation groups and development agencies agreed to work together to preserve the ecosystems while providing development in the region.
Into the Congo: saving bonobos means aiding left-behind communities, an interview with Gay Reinartz
(09/23/2010) Unlike every other of the world's great apes—the gorilla, chimpanzee, and orangutan—saving the bonobo means focusing conservation efforts on a single nation, the Democratic Republic of the Congo. While such a fact would seem to simplify conservation, according to the director of the Bonobo and Congo Biodiversity Initiative (BCBI), Gay Reinartz, it in fact complicates it: after decades of one of world's brutal civil wars, the DRC remains among the world's most left-behind nations. Widespread poverty, violence, politically instability, corruption, and lack of basic infrastructure have left the Congolese people in desperate straits.
Another food goliath falls to palm oil campaign
(09/22/2010) One of the world's biggest food makers, General Mills, has pledged to source only sustainable and responsible palm oil within five years time. With this announcement, General Mills becomes only the most recent food giant to pledge to move away from problematic sources of palm oil, which is used in everything from processed foods to health and beauty products. Nestle made a similar pledge earlier this year after a brutalizing social media campaign that lasted for months while Unilever, the world's biggest palm oil buyer, has been working closely with green groups for years.
An undamaged Amazon produces its own clouds and rain
(09/21/2010) Researchers recently traveled to the remote Brazilian Amazon to investigate how clouds are formed and rain falls in an atmosphere unburdened by human-caused pollution. Studying the atmospheric aerosol particles, which impact cloud formation and particles, above a pristine forests, researchers discovered that when left alone the Amazon acts as its own 'bioreactor': clouds and precipitation are produced by the abundance of plant materials.
How the overlooked peccary engineers the Amazon, an interview with Harald Beck
(09/20/2010) When people think of the Amazon rainforest, they likely think of roaring jaguars, jumping monkeys, marching ants, and squeezing anacondas. The humble peccary would hardly be among the first animals to cross their mind, if they even know such pig-like animals exists! Yet new research on the peccary is proving just how vital these species are to the world's greatest rainforest. As seed dispersers and seed destroyers, engineers of freshwater habitats and forest gaps, peccaries play an immense, long overlooked, role in the rainforest. "Peccaries have the highest density and biomass of any Neotropical mammal species. Obviously these fellows have quite an appetite for almost anything, but primarily they consume fruits and seeds. Their specialized jaws allow them to crush very hard seeds. The cracking sounds can be heard through the thick vegetation long before we could see them. As peccary herds bulldoze through the leaf litter in search for insects, frogs, seeds, and fruits, they destroy (i.e. snap and trample) many seedlings and saplings, sometimes leaving only the bare ground behind," Harald Beck, assistant professor at Towson University in Maryland, told mongabay.com in an interview.
80% of tropical agricultural expansion between 1980-2000 came at expense of forests
(09/02/2010) More than 80 percent of agricultural expansion in the tropics between 1980 and 2000 came at the expense of forests, reports research published last week in the early online edition of the Proceedings of the National Academy of Sciences (PNAS). The study, based on analysis satellite images collected by the United Nations Food and Agricultural Organization (FAO) and led by Holly Gibbs of Stanford University, found that 55 percent of new agricultural land came at the expense of intact forests, while 28 percent came from disturbed forests. Another six percent came from shrub lands.
Could camera traps save wildlife worldwide?
(08/31/2010) It's safe to say that the humble camera trap has revolutionized wildlife conservation. This simple contraption—an automated digital camera that takes a flash photo whenever an animal triggers an infrared sensor—has allowed scientists to collect photographic evidence of rarely seen, and often globally endangered species, with little expense and relative ease—at least compared to tromping through tropical forests and swamps looking for endangered rhino scat . Now researchers with the Wildlife Conservation Society (WCS) and the Zoological Society of London (ZSL) are taking the utility of the camera trap one step further: a study in Animal Conservation uses a novel methodology, entitled the Wildlife Picture Index (WPI), to analyze population trends of 26 species in Bukit Barisan Selatan National Park on the Indonesian island of Sumatra. While the study found a bleak decline in species, it shows the potential of camera traps for moving conservation forward since it marks the first time researchers have used camera traps to analyze long-term population trends of multiple species.
Norway divests from Malaysian logging company after rainforest destruction
(08/24/2010) The Norwegian Government's pension fund sold all its 16 million shares of Samling Global, a Malaysian timber company, after concluding the firm had committed 'serious transgessions' in logging outside of concession areas and destroying protected rainforests, reports the Bruno Manser Fund. The sale, worth a total of $1.2 million, represents about 0.3 percent of the company's outstanding shares based on today's closing market price in Hong Kong.
Satellites show mangrove forest loss even worse than estimated
(08/19/2010) New satellite data shows that human actions are wiping out mangrove forests even faster than previous bleak estimates. Conducted by the US Geological Survey and NASA, the researchers found that mangroves comprise 12.3 percent less area than previously estimated. In total, satellites reveal that mangrove forests cover approximately 53,290 square miles (137,760 square kilometers). "Our assessment shows, for the first time, the exact extent and distribution of mangrove forests of the world at 30 meters spatial resolution, the highest resolution ever," said Dr Chandra Giri from USGS.
146 dams threaten Amazon basin
(08/19/2010) Although developers and government often tout dams as environmentally-friendly energy sources, this is not always the case. Dams impact river flows, changing ecosystems indefinitely; they may flood large areas forcing people and wildlife to move; and in the tropics they can also become massive source of greenhouse gases due to emissions of methane. Despite these concerns, the Amazon basin—the world's largest tropical rainforest—is being seen as prime development for hydropower projects. Currently five nations—Brazil, Bolivia, Colombia, Ecuador, and Peru—are planning over 146 big dams in the Amazon Basin. Some of these dams would flood pristine rainforests, others threaten indigenous people, and all would change the Amazonian ecosystem. Now a new website, Dams in Amazonia, outlines the sites and impacts of these dams with an interactive map.
