(06/13/2011) Germany has backed out of a pledge to commit $50 million a year to Ecuador's Yasuni ITT Initiative, reports Science Insider. The move by Germany potentially upsets an innovative program hailed by environmentalists and scientists alike. This one-of-a-kind initiative would protect a 200,000 hectare bloc in Yasuni National Park from oil drilling in return for a trust fund of $3.6 billion, or about half the market value of the nearly billion barrels of oil lying underneath the area. The plan is meant to mitigate climate change, protect biodiversity, and safeguard the rights of indigenous people.
Environment versus economy: local communities find economic benefits from living next to conservation areas
(06/12/2011) While few would question that conserving a certain percentage of land or water is good for society overall, it has long been believed that protected areas economically impoverish, rather than enrich, communities living adjacent to them. Many communities worldwide have protested against the establishment of conservation areas near them, fearing that less access and increased regulations would imperil their livelihoods. However, a surprising study overturns the common wisdom: showing that, at least in Thailand and Costa Rica, protected areas actually boost local economies and decrease poverty.
90% of tropical forests managed poorly or not at all
(06/07/2011) More than 90 percent of tropical forests are managed poorly or not at all, says a new assessment by the International Tropical Timber Organization (ITTO).
South Sudan’s tropical forests fast disappearing
(06/06/2011) South Sudan’s tropical montane forests are fast disappearing according to new analysis by PRINS Engineering. At current rates, Mount Dongotomea, located in South Sudan’s most biodiverse ecosystem, could be completely stripped of tree cover by 2020.
Photos: Cambodians rally as 'Avatars' to save one of the region's last great rainforests
(05/31/2011) Two hundred Cambodians rallied in Phnom Penh last week to protest the widespread destruction of one of Southeast Asia's last intact lowland rainforests, known as Prey Lang. In an effort to gain wider media attention, protestors donned dress and make-up inspired by the James Cameron film, Avatar, which depicts the destruction of a forest and its inhabitants on an alien world. The idea worked as the rally received international attention from Reuters, CNN (i-report), MSNBC, and NPR, among other media outlets.
Amphibian-plague strikes frogs harder in pristine ecosystems
(05/31/2011) Frog populations worldwide are facing two apocalypses: habitat destruction and a lethal plague, known as chytridiomycosis. Over 30 percent of the world's amphibians are currently threatened with extinction and it is thought at least 120 species have gone extinct in just the last 30 years. Unfortunately, a new study in Proceedings of the National Academy of Sciences (PNAS) finds that the two threats—habitat loss and chytridiomycosis—are likely to leave no frog population undisturbed. According to the study, frogs that live in still-pristine habitats are more susceptible to chytridiomycosis than those that are already suffering from habitat loss.
Restoring forests: an opportunity for Africa
(05/26/2011) Tropical forest news last week was dominated by Indonesia and Brazil. Forest clearing has surged over the past year in parts of the Amazon, the Brazilian Government reported. Meanwhile, Indonesia’s President signed a moratorium on cutting some intact forest areas, as part of a landmark billion-dollar deal with international donors. But new research shows that Africa offers some of the greatest opportunities globally for restoring forests.
Green groups to Japan: don't buy illegally logged wood from Indonesia to aid reconstruction
(05/26/2011) Following Japan's devastating earthquake and tsunami, it needs to rebuild and do so the battered nation has already turned to a neighbor, Indonesia, for timber. However, the Environmental Investigation Agency (EIA) and Indonesian NGO, Telapak, warn that much of the timber that reaches Japan's shores from Indonesia could be illegally logged from rainforests, unless Japan pledges to only purchase legally-certified wood under Indonesia's new assurance system.
Shipping firm pledges to disconnect itself from rainforest destruction
(05/25/2011) The Danish shipping giant Maersk pledged this week to stop purchasing containers with floors made from uncertified tropical hardwood, reports Deutsche Welle press. In an effort to reduce illegal logging and combat climate change, the company will be turning to recycled plastic, bamboo, and tropical wood certified by the Forest Stewardship Council (FSC) for its flooring. The Copenhagen-based firm is the first cargo company to transition to 'green containers' as part of a sustainable business strategy.
Killing in the name of deforestation: Amazon activist and wife assassinated
(05/24/2011) José Cláudio Ribeiro da Silva and his wife, Maria do Espírito Santo da Silva, were gunned down last night in an ambush near their home in the Brazilian state of Pará. Da Silva was known as a community leader and an outspoken critic of deforestation in the region. Police believe the da Silvas were killed by hired assassins because both victims had an ear cut off, which is a common token for hired gunmen to prove their victims had been slain, according to local police investigator, Marcos Augusto Cruz, who spoke to Al Jazeera. Suspicion immediately fell on illegal loggers linked to the charcoal trade that supplies pig iron smelters in the region.
Authorities launch stealth operation in Amazon after satellite images reveal deforestation
(05/24/2011) Brazil’s environmental enforcement agency busted an illegal logging ring following analysis of satellite imagery, reports Globo.
On the edge of extinction, Philippine eagles being picked off one-by-one
(05/23/2011) Down to a few hundred individuals, every Philippine eagle is important if the species is to survive. However, the Philippine Eagle Foundation (PEF) has recently announced that people continue to illegally trap and keep eagles captive. Since December the organization has taken-in four confiscated Philippine eagles (Pithecophaga jefferyi), according to The Philippine Star. One died of a fungal infection after confiscation, while two others has suffered serious injuries.
Photos: the top ten new species discovered in 2010
(05/23/2011) If we had to characterize our understanding of life on Earth as either ignorant or knowledgeable, the former would be most correct. In 250 years of rigorous taxonomic work researchers have cataloged nearly two million species, however scientists estimate the total number of species on Earth is at least five million and perhaps up to a hundred million. This means every year thousands of new species are discovered by researchers, and from these thousands, the International Institute for Species Exploration at Arizona State University selects ten especially notable new species.
Locals clash with 'sustainable' FSC logging company in the Congo
(05/22/2011) Two separate protests against logging companies by local communities have turned violent in the Democratic Republic of Congo (DRC), leaving at least one dead. According to Greenpeace, one of the companies involved in the violence, Sodefor, is sustainably certified by the Forest Stewardship Council (FSC). Given that the industry in DRC is rife with social conflict and corruption, Greenpeace is advocating that FSC place a moratorium on certifying new industrial-style logging concessions in the central African nation.
Uncovering the private lives of Amazon wildlife through camera traps
(05/20/2011) One of the best words to describe Amazon wildlife, including large mammals and birds, is cryptic. A person can spend a day trekking through the dense green and brown foliage of the Amazon and see nothing more than a few insects, maybe a frog here and there if they have good eyes. In fact, researchers have spent years in the jungle and never seen a jaguar, let alone a tapir. Some species like the bushdog and the giant armadillo are even more cryptic. Almost never encountered by people, in some parts of the Amazon they have taken on a mythic status, more rumor around the fire than reality. However, camera traps—automated cameras that take a flash photo whenever an animal triggers an infrared sensor—in the Amazon have begun to reveal long-sought information about the presence and abundance of species, providing new data on range and territories. And even at times giving glimpses into the private lives of species that remain largely shrouded in mystery.
3,000 amphibians, 160 land mammals remain undiscovered—that is if they don't go extinct first
(05/18/2011) Remote little-explored rainforests probably harbor the majority of undiscovered amphibians and land mammals according to a new study in Proceedings of the Royal Society B. The study calculated that it's likely 33% of the world's amphibians and 3% of terrestrial mammals still remain unknown. However, the paper also found that these undiscovered species are likely in worse peril of extinction than already-described species.
Australia forest destruction connected to local products
(05/15/2011) Some of Australia's most popular stores are driving the destruction of native forests, according to a report by a new environmental group Markets for Change (MFC). Furniture, building materials, and paper products were found to be coming at the expense of native forests in Australia and being sold by over 30 businesses in the country, such as Freedom Furniture, Bunnings, Officeworks, Staples, Target, Coles, and Woolsworths.
ConocoPhillips withdraws from oil exploitation in uncontacted indigenous territory
(05/11/2011) ConocoPhillips has announced it is withdrawing from its 45% share of oil drilling in Block 39 of Peru's Amazon rainforest. The withdrawal comes after pressure from indigenous-rights and environmental groups to leave two Peruvian oil blocks—39 and 67—alone, due to the presence of indigenous people who have chosen to remain uncontacted. ConocoPhillips and other companies have been warned they will 'decimate' tribes if they remain. However, Spanish oil company Repsol-YPF still operates in block 39 and is currently doing seismic testing for oil reserves in the untouched region. ConocoPhillips has not divulged what company is taking their place.
Cambodia's wildlife pioneer: saving species and places in Southeast Asia's last forest
(05/11/2011) Suwanna Gauntlett has dedicated her life to protecting rainforests and wildlife in some of the world’s most hostile and rugged environments and has set the trend of a new generation of direct action conservationists. She has designed, implemented, and supported bold, front-line conservation programs to save endangered wildlife populations from the brink of extinction, including saving the Amur Tiger (also known as the Siberian Tiger) from extinction in the 1990s in the Russian Far East, when only about 80 individuals remained and reversing the drastic decline of Olive Ridley sea turtles along the coast of Orissa, India in the 1990s, when annual nestings had declined from 600,000 to a mere 8,130. When she first arrived in Cambodia in the late 1990s, its forests were silent. 'You couldn’t hear any birds, you couldn’t hear any wildlife and you could hardly see any signs of wildlife because of the destruction,' Gauntlett said. Wildlife was being sold everywhere, in restaurants, on the street, and even her local beauty parlor had a bear.
Liberia fights illegal logging through agreement with EU
(05/10/2011) The tiny West African nation of Liberia (about the size of the US state of Virginia) is the most recent country to work with the European Union (EU) on ending the illegal logging trade. Yesterday the EU and Liberia signed a Voluntary Partnership Agreement (VPA) that would make certain no raw wood or wood products exported from Liberia to the EU would have been illegally cut.
Chainsaw Milling: Domestic Unregulated Deforestation Agents or Local Entrepreneurs?
(05/10/2011) Chainsaw milling: supplier to local markets, provides a much needed insight into the generally unregulated on-site conversion of logs into lumber using chainsaws for tropical in-country domestic markets. Tropical forest chainsaw milling juxtaposes local economic benefit with lack, unregulated oversight.
Girls Scouts censors Facebook page after coming under criticism for product linked to rainforest loss
(05/04/2011) Girls Scouts USA has censored its Facebook page after receiving comments criticizing the organization, according to Rainforest Action Network (RAN). RAN along with Change.org and two Girl Scout activists, Rhiannon Tomtishen and Madison Vorva, declared today a social media day of activism against the Girl Scouts for using palm oil in their popular cookies. The oil has been linked to rainforest destruction in Indonesia and Malaysia.
Forgotten species: the endearing Tenkile tree kangaroo
(05/03/2011) With their long snout, furry body, soft eyes, and, at times, upright stance, tree kangaroos often remind me of the muppets. Of course, if there were any fairness in the world, the muppets would remind me of tree kangaroos, since kangaroos, or macropods, have inhabited the Earth for at least 5 million years longer than Jim Henson’s muppets. But as a child of the 1980s, I knew about muppets well before tree kangaroos, which play second fiddle in the public imagination to their bigger, boxing cousins. This is perhaps surprising, as tree kangaroos possess three characteristics that should make them immensely popular: they are mammals, they are monkey-like (and who doesn't like monkeys?), and they are desperately 'cute'.
Conservation organizations ask Tanzania to reconsider UNESCO status for Eastern Arc Mountains
(05/02/2011) Tanzanian President Jakaya Kikwete has recently stated he would withdraw the application to list two Eastern Arc Mountains as UNESCO World Heritage sites: Udzungwa and Uluguru Mountains. However, ten NGOS, both local and international, have asked the president to reconsider, according to The Citizen.
Controversial Brazilian mega-dam receives investment of $1.4 billion
(05/02/2011) Brazil's most controversial mega-dam, Belo Monte, which is moving full steam ahead against massive opposition, has received an extra infusion of cash from Vale, a Brazilian-run mining company.
Elephants: the gardeners of Asia's and Africa's forests
(04/25/2011) It seems difficult to imagine elephants delicately tending a garden, but these pachyderms may well be the world's weightiest horticulturalist. Elephants both in Asia and Africa eat abundant amounts of fruit when available; seeds pass through their guts, and after expelled—sometimes tens of miles down the trail—sprouts a new plant if conditions are right. This process is known by ecologists as 'seed dispersal', and scientists have long studied the 'gardening' capacities of monkeys, birds, bats, and rodents. Recently, however, researchers have begun to document the seed dispersal capacity of the world's largest land animal, the elephant, proving that this species may be among the world's most important tropical gardeners.
Mexican environmental activist shot dead
(04/25/2011) Javier Torres Cruz, 30, who fought illegal deforestation by drug traffickers in the Mexican state of Guerroro, was murdered a week ago. A member of the local NGO, Environmental Organization of the Coyuca and Petatlán Mountains, Torres Cruz was known as an outspoken activist against illegal logging in the mountainous dry forest region. Logging in the region is primarily linked to fields of poppies for the illegal drug trade.
What does Nature give us? A special Earth Day article
(04/22/2011) There is no question that Earth has been a giving planet. Everything humans have needed to survive, and thrive, was provided by the natural world around us: food, water, medicine, materials for shelter, and even natural cycles such as climate and nutrients. Scientists have come to term such gifts 'ecosystem services', however the recognition of such services goes back thousands of years, and perhaps even farther if one accepts the caves paintings at Lascaux as evidence. Yet we have so disconnected ourselves from the natural world that it is easy—and often convenient—to forget that nature remains as giving as ever, even as it vanishes bit-by-bit. The rise of technology and industry may have distanced us superficially from nature, but it has not changed our reliance on the natural world: most of what we use and consume on a daily basis remains the product of multitudes of interactions within nature, and many of those interactions are imperiled. Beyond such physical goods, the natural world provides less tangible, but just as important, gifts in terms of beauty, art, and spirituality.
Demand for gold pushing deforestation in Peruvian Amazon
(04/19/2011) Deforestation is on the rise in Peru's Madre de Dios region from illegal, small-scale, and dangerous gold mining. In some areas forest loss has increased up to six times. But the loss of forest is only the beginning; the unregulated mining is likely leaching mercury into the air, soil, and water, contaminating the region and imperiling its people. Using satellite imagery from NASA, researchers were able to follow rising deforestation due to artisanal gold mining in Peru. According the study, published in PLoS ONE, Two large mining sites saw the loss of 7,000 hectares of forest (15,200 acres)—an area larger than Bermuda—between 2003 and 2009.
Forest Governance Measuring Tools within Collaborative Governance of Tropical Landscapes: Book Review
(04/19/2011) Conservation projects at the landscape level in the tropics often require collaborative governance because there are many factors that may be involved with conserving and enhancing the ecosystem services with a landscape-based project. Yet as eloquently described in Collaborative Governance of Tropical Landscapes, significant issues remain in designing and implementing effective collaborative governance models for tropical landscapes.
Scientists urge Papua New Guinea to declare moratorium on massive forest clearing
(04/19/2011) Forests spanning an area larger than Costa Rica—5.6 million hectares (13.8 million acres)—have been handed out by the Papua New Guinea government to foreign corporations, largely for logging. Granted under government agreements known as Special Agricultural and Business Leases (SABLs), the land leases circumvent the nation's strong laws pertaining to communal land ownership. Now, the Association for Tropical Biology and Conservation (ATBC), the world's largest professional society devoted to studying and conserving tropical forests, is urging the Papua New Guinea government to declare a moratorium on SABLs.
NASA image reveals extent of 2010 Amazon drought
(04/17/2011) NASA has revealed a satellite image of the crippling effect of last year's record-breaking drought on the Amazon ecosystem. For those of you counting, that's two record droughts in the Amazon Basin in 5 years.
Indonesia and the EU reach agreement on illegal wood trade
(04/17/2011) A new agreement will work to keep illegal wood from Indonesia out of European Union markets. The Voluntary Partnership Agreement (VPA) will force Indonesia to only ship wood to the EU that has been approved as legal by a national authority, while EU customs workers are set to send any unapproved wood back to Indonesia. The VPA is a step forward in tackling the illegal timber market in Indonesia that is estimated to be worth $1 billion and has been responsible, in part, for leveling rainforests across the Indonesia islands.
Vietnam creates reserve for newly-discovered, nearly-extinct mammal, the saola
(04/14/2011) The Vietnam government and local people have approved a Saola Natural Reserve to protect one of the world's most endangered—and most elusive—mammals. Only discovered by the outside world in 1992, the saola (Pseudoryx nghetinhensis) inhabits the lush forests of the Annamite Mountains. No one knows how many saola remain, but it has been classified as Critically Endangered as it is likely very few. Recently, conservationist William Robichaud told mongabay.com that the saola was "perhaps the most spectacular zoological discovery of the 20th century", comparing it only to the discovery of the okapi in central Africa in 1900.
From the Serengeti to Lake Natron: is the Tanzanian government aiming to destroy its wildlife and lands?
(04/14/2011) What's happening in Tanzania? This is a question making the rounds in conservation and environmental circles. Why is a nation that has so much invested in its wild lands and wild animals willing to pursue projects that appear destined not only to wreak havoc on the East African nation's world-famous wildlife and ecosystems, but to cripple its economically-important tourism industry? The most well known example is the proposed road bisecting Serengeti National Park, which scientists, conservationists, the UN, and foreign governments alike have condemned. But there are other concerns among conservationists, including the fast-tracking of soda ash mining in East Africa's most important breeding ground for millions of lesser flamingo, and the recent announcement to nullify an application for UNESCO Heritage Status for a portion of Tanzania's Eastern Arc Mountains, a threatened forest rich in species found no-where else. According to President Jakaya Kikwete, Tanzania is simply trying to provide for its poorest citizens (such as communities near the Serengeti and the Eastern Arc Mountains) while pursuing western-style industrial development.
Satellite evidence of deforestation in uncontacted tribe's territory sparks legal action
(04/12/2011) The destruction of 3,600 hectares (8,900 acres) of the Gran Chaco forest in Paraguay by large Brazilian cattle ranching companies has led to a legal complaint filed by a local indigenous-rights organization, since the land in question was one of the last refuges of a group of uncontacted indigenous people in the Ayoreo-Totobiegosode tribe. The loss of the forest was revealed in part by satellite images of the remote area.
Giant fish help grow the Amazon rainforest
(04/12/2011) A fruit in the flooded Amazon falls from a tree and plops in the water. Before it can even sink to the floor, a 60-pound monster fish with a voracious appetite gobbles it. Nearly a week later—and miles away—the fish expels its waste, including seeds from the fruit eaten long ago and far away. One fortunate seed floats to a particularly suitable spot and germinates. Many years later the new fruit tree is thriving, while the same monster-fish returns from time-to-time, waiting for another meal to drop from the sky. This process is known as seed-dispersal, and while researchers have studied the seed-dispersal capacity of such species as birds, bats, monkeys, and rodents, one type of animal is often overlooked: fish.
Cambodian prime minister cancels titanium mine project citing impact on biodiversity and local people
(04/11/2011) In a surprise move, the Cambodian Prime Minister, Sandech Hun Sen, has cancelled a titanium strip mine project in one of Southeast Asia’s last great intact forest ecosystems, the Cardamom Mountains. According to a press release sent out by the Cambodian government the mine was canceled due to "concerns of the impact on the environment, biodiversity and local livelihoods" of villagers. The mine, which was planned to sit directly in the migration route for the largest population of Asian elephants in Cambodia, had been largely opposed by locals in the region who spent years developing eco-tourism in the region.
Indigenous group claims Ecuadorian government complicit in 'genocide'
(04/06/2011) Ecuador's paramount indigenous organization has filed a legal complaint against the government, including President Rafael Correa, for allegedly participating in 'genocide' against indigenous people in the Amazon. The Confederation of Indigenous Nationalities of Ecuador (CONAIE) is arguing that expanding oil exploration and mining is imperiling the lives of uncontacted tribes that have chosen voluntary isolation known as the Tagaeri and the Tarmenane, reports the AFP.
Japan disaster to put logging pressure on rainforests in Indonesia, Malaysia
(04/05/2011) The tragic earthquake and tsunami that hit Japan last month is likely to boost wood imports into the recovering nation, adding increased pressure on the already imperiled rainforests of Southeast Asia. Even before the disaster, Japan was the world's number one importer of wood chips and plywood and the second largest importer of logs. Japan usually imports plywood from China, Malaysia, and Indonesia, however the forests of Southeast Asia are facing tremendous loss due to logging and clearing for industrial-scale agriculture, such as palm oil.
Vanishing mangroves are carbon sequestration powerhouses
(04/05/2011) Mangroves may be the world's most carbon rich forests, according to a new study in Nature Geoscience. Measuring the carbon stored in 25 mangrove forests in the Indo-Pacific region, researchers found that mangroves forests stored up to four times as much carbon as other tropical forests, including rainforests. "Mangroves have long been known as extremely productive ecosystems that cycle carbon quickly, but until now there had been no estimate of how much carbon resides in these systems. That's essential information because when land-use change occurs, much of that standing carbon stock can be released to the atmosphere," explains co-author Daniel Donato, a postdoctoral research ecologist at the Pacific Southwest Research Station in Hilo, Hawaii.
The saola: rushing to save the most 'spectacular zoological discovery' of the 20th Century
(04/04/2011) The saola (Pseudoryx nghetinhensis) may be the most enigmatic, beautiful, and endangered big mammal in the world—that no one has ever heard of. The shy ungulate looks like an African antelope—perhaps inhabiting the wide deserts of the Sahara—but instead it lives in the dense jungles of Vietnam and Laos, and is more related to wild cattle than Africa's antelopes. The saola is so unusual that is has been given its own genus: Pseudoryx, due to its superficial similarities to Africa's oryx. In the company of humans this quiet forest dweller acts calm and tame, but has yet to survive captivity long. Yet strangest of all, the 200 pound (90 kilogram) animal remained wholly unknown to science until 1992.
'Luck and perseverance': new plant genus discovered in Amazon
(03/31/2011) The discovery of a new plant species is not uncommon, especially in places of remarkable biodiversity such as the Amazon rainforest. However, discovering a new plant genus, a taxonomic rank above species, is, according to Henk van der Werff fromt the Missouri Botanical Garden (MBG), "a matter of luck and perseverance". Researchers with the Missouri Botanical Garden have been blessed with both as they have announced two new species of Amazonian plants, one from Ecuador and one from Peru, that comprise a completely new genus: named, Yasunia, since the plant was originally discovered in Ecuador's vast Yasuni National Park.
Last year's drought hit Amazon hard: nearly a million square miles impacted
(03/29/2011) A new study on its way to being published shows that the Amazon rainforest suffered greatly from last year's drought. Employing satellite data and supercomputing technology, researchers have found that the Amazon was likely hit harder by last year's drought than a recent severe drought from 2005. The droughts have supported predictions by the Intergovernmental Panel on Climate Change's (IPCC) that climate change, among other impacts, could push portions of the Amazon to grasslands, devastating the world's greatest rainforest. "The greenness levels of Amazonian vegetation—a measure of its health—decreased dramatically over an area more than three and one-half times the size of Texas and did not recover to normal levels, even after the drought ended in late October 2010," explains the study's lead author Liang Xu of Boston University.
Amazon still neglected by researchers
(03/28/2011) Although the Amazon is the world's largest tropical forest, it is not the most well known. Given the difficulty of access along with the fear of disease, dangerous species, indigenous groups, among other perceived perils, this great treasure chest of biology and ecology was practically ignored by scientists for centuries. Over the past few decades that trend has changed, however even today the Amazon remains lesser known than the much smaller, and more secure, tropical forests of Central America. A new study in mongabay.com's open access journal Tropical Conservation Science, which surveyed two prominent international tropical ecology journals (Biotropica and Journal of Tropical Ecology) between 1995 and 2008, finds that Central America was the subject of twice as many studies as the Amazon. In fact, according to the authors, much of the Amazon remains terra incognito to researchers, even as every year more of the rainforest is lost to human impacts.
Leaf harvesting impacts Amazon palm
(03/28/2011) Overexploitation of wildlife doesn't just threaten animals such as bluefin tuna, pangolins, and parrots, but plants as well. Leaves from the carana or puy palm (Lepidocaryum tenue) are used for thatching buildings in the northwestern Amazon, however a recent study in mongabay.com's open access journal Tropical Conservation Science finds that the overharvesting could imperil a palm's ability to survive.
Bill Clinton takes on Brazil's megadams, James Cameron backs tribal groups
(03/28/2011) Former US President, Bill Clinton, spoke out against Brazil's megadams at the 2nd World Sustainability Forum, which was also attended by former California governor, Arnold Schwarzenegger, and film director, James Cameron, who has been an outspoken critic of the most famous of the controversial dams, the Belo Monte on the Xingu River.
Logged forests in Vietnam retain significant biodiversity, including dipterocarp trees
(03/28/2011) Little remains of Vietnam's primary forest: as of 2005 only 12% of Vietnam forest was classified as primary. While deforestation rates have lessened since the end of the 1990s, survival of species in Vietnam depends in part on secondary, logged, and degraded forests. A new study in mongabay.com's open access journal Tropical Conservation Science finds that logged forests in southern Vietnam still retain significant biodiversity of trees, including important conservation species, such as Dipterocarp trees.
Alien plants invade Nigerian protected 'gene bank'
(03/28/2011) Very few studies have been conducted on invasive species in Nigeria, however a new study in mongabay.com's open access journal Tropical Conservation Science has discovered 25 invasive plants in a field gene bank at the National Center for Genetic Resources and Biotechnology (NASGRAB) in Ibadan. The gene bank is used to establish populations of important and, in some cases threatened, native plant species. The gene bank spans 12 hectares, but the study found that 18% of the area was overtaken with invasive species that likely compete with the protected Nigerian plants for nutrients, space, and light. Among the 25 invasive species, 14 were herbs, 8 were vines, 2 were shrubs, and one was a tree.
Cloud forest dung beetles in India point to 'fossil ecosystem'
(03/28/2011) In the cloud forests and grasslands of India's Western Ghats, known as sholas, researchers have for the first time comprehensively studied the inhabiting dung beetle populations. The resulting study in mongabay.com's open access journal Tropical Conservation Science, has led scientists to hypothesize that the beetles in concordance with the sheep-like mammal, the nilgiri tahr (Nilgiritragus hylocrius), may be a sign of a 'fossil ecosystem'.
