(02/20/2014) Nicaragua's plans for a canal linking the Pacific and Atlantic Oceans could trigger an environmental disaster through habitat destruction and alteration, introduction of non-native species, pollution, and sedimentation, warns a commentary published in this week's issue of Nature.
Handful of species key to ecosystem health, finds study
(01/20/2014) While conducting field research in the humid salt marshes of Sapelo Island, scientists Marc Hensel and Brian Silliman made an astonishing discovery: species type, not just quantity, is vital for maintaining healthy ecosystems. For decades, scientists believed that preserving the largest number of species was critical for ecosystem function, regardless of their genetic makeup.
Court orders logging company to clean up pollution disaster in Chile wetlands
(01/17/2014) Chile is probably best known for its volcanoes, earthquakes and the formidable peaks of the Andes, but as a country that spans 4,300 km (2,670 miles) from top to bottom, it also boasts a huge variety of bird life. And, until recently, it was home to what was thought to be the largest population of black-necked swans (Cygnus melancoryphus) in South America. Not long ago, these swans, as well as 100 other species of rare or vulnerable bird species, could be seen nesting in the Carlos Anwandter Nature Sanctuary in Valdivia, a Ramsar site that covers 12,000 acres in the south of Chile. But in 2004 the swans began to die.
Good news: Refuge for last blue-throated macaws doubles in size in Bolivia
(01/02/2014) A reserve that is home to the world's largest population of the critically endangered blue-throated macaw (Ara glaucogularis) has been more than doubled in size, reports the American Bird Conservancy (ABC), a group that helped fund the expansion.
Featured video: U.S. forests decimated for 'green' bio-energy in Europe
(12/12/2013) Wetland forests in the southern U.S. are becoming the victims of a drive for so-called green energy in Europe, according to activist group Dogwood Alliance, which has produced a new video highlighting the issue. The activists contend that bio-energy that depends on chopping down forests not only devastates vital ecosystems, but actually emits more greenhouse gases than traditional fossil fuels.
Armored giant turns out to be vital ecosystem engineer
(10/24/2013) The giant armadillo (Priodontes maximus) is not called a giant for nothing: it weighs as much as a large dog and grows longer than the world's biggest tortoise. However, despite its gigantism, many people in its range—from the Amazon to the Pantanal—don't even know it exists or believe it to be more mythology than reality. This is a rare megafauna that has long eluded not only scientific study, but even basic human attention. However, undertaking the world's first long-term study of giant armadillos has allowed intrepid biologist, Arnaud Desbiez, to uncovered a wealth of new information about these cryptic creatures. Not only has Desbiez documented giant armadillo reproduction for the first time, but has also discovered that these gentle giants create vital habitats for a variety of other species.
Scientists discover that threatened bird migrates entirely within Amazon Basin
(09/11/2013) When one thinks of bird migrations, it's usually a north-south route that follows seasonal climates. But researchers in the Amazon have tracked, for the first time, a largely-unknown long-distance migration that sticks entirely to the Amazon Basin. Using satellite telemetry, scientists tracked a pair of Orinoco geese (Neochen jubata) from Peru and a male from Western Brazil, who both migrated to the Llanos de Moxos, a vast savanna and Amazonian watershed in Bolivia. The research has shown that the Orinoco geese—which breeds in both Peru and Brazil—depends on wetlands in the Llanos de Moxos for much of the year.
Iraq gets its first national park: just call it Eden
(08/19/2013) Late last month, the Iraqi Council of Ministers approved the nation's first national park: the Mesopotamian marshes, which some scholars believe were the site of the historical Garden of Eden. The establishment of the park is a major milestone for a nation still plagued by violence with the park itself linked to the ravages of the Saddam Hussein regime.
Southern U.S. logging soars to meet foreign biofuel demand
(06/06/2013) In order to meet the European Union's goal of 20% renewables by 2020, some European utility companies are moving away from coal and replacing it with wood pellet fuel. The idea is simple: trees will regrow and recapture the carbon released in the burning of wood pellets, making the process supposedly carbon-neutral. But just like other simple ideas, it misses out important details that can turn it on its head.
New endangered list for ecosystems modeled after 'Red list' for species
(05/09/2013) The IUCN has unveiled the first iteration of its new Red List of Ecosystems, a ranking of habitats worldwide.
Unconventional swine: how invasive pigs are helping preserve biodiversity in the Pantanal
(05/06/2013) Ordinarily, invasive and exotic species are a grave threat to native wildlife: outcompeting local species, introducing parasites and disease, and disturbing local ecological regimes. A unique case in the Brazilian Pantanal, however, has turned the tables; here, an introduced mammal has actually aided the conservation of native wildlife.
World's rarest duck on the rebound in Madagascar
(05/01/2013) After a final sighting in 1991, the Madagascar pochard was thought to have vanished for good. But this diving duck was rediscovered in 2006 when a flock of 22 individuals was found on Lake Matsaborimena in northern Madagascar by conservationists during an expedition. Soon after Madagascar pochard eggs were taken and incubated in a joint captive breeding program by Durrell, the Wildfowl & Wetlands Trust (WWT), the Peregrine Fund, Asity Madagascar, and Madagascar government, which recently announced that the population—both captive and wild—has nearly quadrupled.
Two new frog genera discovered in India's Western Ghats, but restricted to threatened swamp-ecosystems
(04/22/2013) The misty mountains of the Western Ghats seem to unravel new secrets the more you explore it. Researchers have discovered two new frog genera, possibly restricted to rare and threatened freshwater swamps in the southern Western Ghats of India. The discoveries, described in the open-access journal Zootaxa, prove once again the importance of the mountain range as a biodiversity hotspot.
Iraqi who is bringing back the Garden of Eden wins top environment award
(04/16/2013) The vast Mesoptomian marshes in southern Iraq were said to be the site of the original Garden of Eden. On their fringes have risen and fallen 12,000 years of Sumerian, Assyrian, Chaldean, Persian and Arab civilizations. Organized farming is thought to have begun here, as did the first cities and writing. In legend, Gilgamesh fell asleep on the water side and let slip from his fingers the plant of eternal youth. Abraham was said to have been born here and explorers like Sir Wilfred Thesiger made their name here.
Cambodia loses half its seasonal wetlands in 10 years
(03/18/2013) Cambodia lost more than half of its seasonally flooded grasslands in ten years due to industrial agricultural conversion, abandonment of traditional farming, and illegal drainage, putting several endangered bird species at risk and undermining traditional livelihoods in the region, reports a new study published in the journal Conservation Biology.
Bolivia leads the way in wetland protection
(03/04/2013) Bolivia continues to be a champion for Amazonian conservation. On February 2, 2013, Bolivia celebrated World Wetlands Day with the designation of more than 6.9 million hectares of the Llanos de Moxos to the Ramsar Convention's Wetlands of International Importance. In addition to being the largest Ramsar designation to date, Bolivia now claims 14.8 million hectares of protected wetland, making it the leading Contracting Party out of 164 participating countries in terms of Ramsar site surface area.
Deforestation, wetlands loss in Brazil and Indonesia generated 45b tons of CO2 in 20 years
(02/22/2013) The United Nations Food and Agriculture Organization (FAO) has launched a global set of statistics on carbon emissions from deforestation, agriculture and other forms of land use for the 1990-2010 period.
World has lost half its wetlands
(11/29/2012) Half of the worlds wetlands have been destroyed in just the last 100 years, says a new report. Published by the Economics of Ecosystems and Biodiversity (TEEB), the report found that of the 25 million square kilometers of wetlands that existed in 1900 just 12.8 million square kilometers now remain. The rate of destruction varies geographically with notable loses in East Asia running at 1.6 per cent per year. In places where aquaculture, over-exploitation (e.g. unsustainable harvesting of fish) and storm damage have been severe, the rate of destruction can be as high as 80 percent.
Mangrove deforestation 3x worse for climate than rainforest loss
(09/07/2012) Degradation and destruction of the world's seagrasses, tidal marshes, and mangroves may generate up to a billion tons in carbon dioxide emissions annually, reports a new study.
Flooded savannas in Latin America shrinking 3 times faster than rainforests
(08/22/2012) Flooded grasslands and savannas in Latin America are disappearing nearly three times faster than tropical rainforests in the region, finds a new study published in the journal Biotropica.
Protecting jaguars a good business decision for ranchers
(06/20/2012) Live jaguars are worth considerably more for ecotourism than they livestock they kill, according to a study presented at the annual meeting of the Association for Tropical Biology and Conservation in Bonito, Brazil.
Global wetlands shrink 6% in 15 years
(05/14/2012) Global wetlands declined by six percent between 1993 and 2007 due to conversion for agriculture, drainage, and water diversion, reports a new satellite-based assessment published by European researchers in Geophysical Research Letters.
Photos of the day: a celebration of wetlands (for World Wetlands Day)
(02/02/2012) Forget the groundhogs, February 2nd is also World Wetland Day, commemorating the historic convention of wetlands in Ramsar, Iran in 1971. The Ramsar Treaty was an international agreement meant to address the loss and degradation of wetlands worldwide.
Invasion!: Burmese pythons decimate mammals in the Everglades
(01/30/2012) The Everglades in southern Florida has faced myriad environmental impacts from draining for sprawl to the construction of canals, but even as the U.S. government moves slowly on an ambitious plan to restore the massive wetlands a new threat is growing: big snakes from Southeast Asia. A new paper in the Proceedings of the National Academy of Sciences (PNAS) has found evidence of a massive collapse in the native mammal population following the invasion of Burmese pythons (Python molurus bivittatus) in the ecosystem. The research comes just after the U.S. federal government has announced an importation ban on the Burmese python and three other big snakes in an effort to safeguard wildlife in the Everglades. However, the PNAS study finds that a lot of damage has already been done.
Protecting original wetlands far preferable to restoration
(01/26/2012) Even after 100 years have passed a restored wetland may not reach the state of its former glory. A new study in the open access journal PLoS Biology finds that restored wetlands may take centuries to recover the biodiversity and carbon sequestration of original wetlands, if they ever do. The study questions laws, such as in the U.S., which allow the destruction of an original wetland so long as a similar wetland is restored elsewhere.
U.S. implements snake ban to save native ecosystems
(01/25/2012) Last week the U.S. Fish and Wildlife Service (USFWS) announced it was banning the importation and sale across state lines of four large, non-native snakes: the Burmese python (Python molurus bivittatus), the yellow anaconda (Eunectes notaeus), and two subspecies of the African python (Python sebae). Although popular pets, snakes released and escaped into the wild have caused considerable environmental damage especially in the Florida Everglades.
Economic slowdown leads to the pulping of Latvia's forests
(01/23/2012) The economic crisis has pushed many nations to scramble for revenue and jobs in tight times, and the small Eastern European nation of Latvia is no different. Facing tough circumstances, the country turned to its most important and abundant natural resource: forests. The Latvian government accepted a new plan for the nation's forests, which has resulted in logging at rates many scientists say are clearly unsustainable. In addition, researchers contend that the on-the-ground practices of state-owned timber giant, Latvijas Valsts meži (LVM), are hurting wildlife and destroying rare ecosystems.
Conserving Ecuador's Paramos, the alpine tundra ecosystem of the Andes
(01/17/2012) Grupo de Trabajo en Páramos del Ecuador (GTP) is a remarkable self-organized group of páramo experts that have met over the past 13 years in Quito, Ecuador. Páramo is an alpine tundra ecosystem which is located in the northern Andes of South America and adjacent southern Central America. Recently, the Grupo de Trabajo en Páramos del Ecuador published an excellent summary of their analysis from the past 13 years. Robert Hofstede, one of the editors of Páramo: Paisaje estudiado, habitado, manejado e institucionalizado, recently sat down with Mongabay.com and discussed the situation of páramo conservation in Ecuador.
Eco-toilets help save hippos and birds in Kenya
(01/04/2012) It may appear unintuitive that special toilets could benefit hippos and other wetland species, but the Center for Rural Empowerment and the Environment (CREE) has proven the unique benefits of new toilets in the Dunga Wetlands on Lake Victoria's Kenyan side. By building ecologically-sanitary (eco-san) toilets, CREE has managed to alleviate some of the conflict that has cropped up between hippos and humans for space.
Locals key to saving primate-rich wetlands in Cote D'Ivoire
(12/12/2011) Saved from being converted into a vast palm oil plantation by PALM-CI in 2009, the Ehy Tanoé wetlands and forest in the Cote D'Ivoire (Ivory Coast) is home to three gravely endangered primates and as well as many other species. Since 2006, a pilot community management program has been working to protect the 12,000 hectare area, and a new study in mongabay.com's open access journal Tropical Conservation Science finds that long-term conservation of the Ehy Tanoé wetlands and forest is, in fact, vital for locals who depend on the area for hunting, fishing, firewood, building materials, and medicinal plants. In addition, the study finds that the ecosystem has special cultural and spiritual importance to locals.
Extinct frog rediscovered in Israel
(11/21/2011) After its marshland was drained, researchers thought the Hula painted frog (Discoglossus nigriventer) had vanished for good. However a patrol at the Ha-Hula lake in Israel recently discovered a single female amphibian that turned out to be the long-lost, and long-sought, Hula painted frog.
Putting people to work: restoring our ecosystems, sequestering carbon
(10/02/2011) President Obama's sole focus of his September 8th speech to the United States Congress was job creation. He closed his speech by summoning an earlier time of promise: "President Kennedy once said, ' Our problems are man-made—therefore they can be solved by man. And man can be as big as he wants.' These are difficult years for our country. But we are Americans. We are tougher than the times we live in, and we are bigger than our politics have been. So let's meet the moment. Let's get to work..." Inspiration is surely needed because in addition to the United States, where unemployment remains at about 9 percent, severe unemployment is found throughout the world, with Greece, Spain, and South Africa, for example, having 2011 summer unemployment rates at over 16, 20, and 25 percent, respectively.
Valuing Ecosystem Services: The Case of Multi-functional Wetlands
(05/16/2011) Valuing Ecosystem Services: The Case of Multi-functional Wetlands provides the clearest guide yet to describing and implementing in a systematic fashion payments for ecosystems services (PES) strategies for wetland protection mechanisms. By focusing initially on frameworks and obstacles to implementation of wetland protection strategies such as property rights, measuring and monitoring, behavior and compensation, cultural barriers and external factors, the authors posit that is possible to effectively value multi-functional wetlands.
Ten-year-old takes on KFC for destroying US forests
(05/15/2011) Cole Rasenberger's quest to save forests in the US South started as a school assignment to 'be an activist' about something important to him. However, after learning from Dogwood Alliance that coastal forests in North Carolina are being destroyed to make throw-away paper packaging for big fast food companies—such as McDonalds and KFC—Cole Rasenberger, at the age of 8, became more than an activist; he became an environmental leader! He started by targeting McDonalds directly. With the help of 25 friends, and his elementary school administration, he got every student in his school to sign postcards to McDonalds. In all, Cole sent 2,250 postcards to McDonalds.
North America's tiniest turtle vanishing
(05/12/2011) Despite decades of conservation work, populations of North America's smallest turtle, the bog turtle (Glyptemys muhlenbergii), is continuing to decline. Habitat destruction, invasive plants, road-kill, and the illegal pet trade have all played a role in the bog turtle historic decline, but researchers are now reporting increased mortalities across bog turtle populations, bringing fears of disease or an as-yet-unnamed environmental issue.
Beaver dam lessens impact of massive oil spill in Canada
(05/09/2011) The Canadian province of Alberta has suffered its worst oil spill in 35 years with 28,000 barrels of oil (over a million gallons) spilling from a ruptured pipeline operated by Plains Midstream Canada in the Canadian boreal forest. The spill has sullied wetlands near Peace River.
New eco-tour to help save bizarre antelope in 'forgotten' region
(05/01/2011) Imagine visiting a region that is largely void of tourists, yet has world-class bird watching, a unique Buddhist population, and one of the world's most bizarre-looking and imperilled mammals: the saiga. A new tour to Southern Russia hopes to aid a Critically Endangered species while giving tourists an inside look at a region "largely forgotten by the rest of the world," says Anthony Dancer. Few species have fallen so far and so fast in the past 15 years as Central Asia's antelope, the saiga. Its precipitous decline is reminiscent of the bison or the passenger pigeon in 19th Century America, but conservationists hopes it avoids the fate of the latter.
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.
More biodiversity equals cleaner water, but why?
(04/07/2011) A new landmark study not only proves that adding more species to a freshwater stream linearly increases the ecosystem's ability to clean pollutants, but also shows why. The study, published in Nature found that by increasing the biodiversity of a lab controlled mini-stream from one algae species to eight caused the ecosystem to soak up nitrate pollution 4.5 times faster on average. To conduct the experiment, researchers used plastic to create 150 mini model streams. Molding the plastic, they recreated real stream-like habitats such as pools, runs, and eddies. Different species of algae gravitated toward particular mini-habitats, creating special ecological niches and allowing more of the stream to be utilized by the algae for soaking up the nitrate pollution. Less utilization of the available habitats resulted in a dirtier river and vice-versa.
How to save the Pantanal and increase profits for the cattle industry
(03/28/2011) The Pantanal spanning Brazil, Bolivia, and Paraguay is the world's largest wetland—the size of Florida—and home to a wide-variety of charismatic species, such as jaguars, capybaras, and giant anteaters. However, the great wetland is threatened by expansion in big agriculture and an increasingly intensive cattle industry. Yet there is hope: a new study by Wildlife Conservation Society of Brazil (WCS-Brazil) researchers has found that cattle and the ecosystem can exist harmoniously. By replacing current practices with rotational grazing, cattle ranchers gain a healthier herd and more profits while safeguarding the ecological integrity and wildlife of the world's largest wetland system. The study published in mongabay.com's open access journal Tropical Conservation Science is a rare instance of a win-win situation.
Foreign big agriculture threatens world's second largest wildlife migration
(03/07/2011) As the world's largest migration in the Serengeti plains—including two million wildebeest, zebra, and Thomson's gazelles—has come under unprecedented threat due to plans for a road that would sever the migration route, a far lesser famous, but nearly as large migration, is being silently eroded just 1,370 miles (2,200 kilometers) north in Ethiopia's Gambela National Park. The migration of over one million white-eared kob, tiang, and Mongalla gazelle starts in the southern Sudan but crosses the border into Ethiopia and Gambela where Fred Pearce at Yale360 reports it is running into the rapid expansion of big agribusiness. While providing habitat for the millions of migrants, Gambela National Park's land is also incredibly fertile enticing foreign investment.
Malaysian palm oil producers destroying Borneo peat forests faster than ever before
(02/01/2011) Peatlands and rainforests in Malaysia's Sarawak state on the island of Borneo are being rapidly destroyed for oil palm plantations, according to new studies by environmental group Wetlands International and remote sensing institute Sarvision. The analysis shows that more than one third (353,000 hectares or 872,000 acres) of Sarawak's peatswamp forests and ten percent of the state's rainforests were cleared between 2005 and 2010. About 65 percent of the area was converted for oil palm, which is replacing logging as timber stocks have been exhausted by unsustainable harvesting practices.
Rivers worldwide in peril: society treats symptoms, ignores causes
(09/29/2010) Dams, agricultural runoff, pesticides, sewage, mercury pollution from coal plants, invasive species, overconsumption, irrigation, erosion from deforestation, wetland destruction, overfishing, aquaculture: it's clear that the world's rivers are facing a barrage of unprecedented impacts from humans, but just how bad is the situation? A new global analysis of the world's rivers is not comforting: the comprehensive report, published in Nature, finds that our waterways are in a deep crisis which bridges the gap between developing nations and the wealthy west. According to the study, while societies spend billions treating the symptoms of widespread river degradation, they are still failing to address the causes, imperiling both human populations and freshwater biodiversity.
Nearly half of the world's wetlands used for crops
(09/27/2010) Wetlands used for crops have expanded significantly over the past eighty years. According to a new study in the open-access journal Tropical Conservation Science, wetlands being utilized for crop production has jumped from 25 percent in 1926 to 43 percent in 2006 of the world's wetlands as identified by the Ramsar Convention on Wetlands.
Visiting the Gulf: how wildlife and people are faring in America's worst environmental disaster, an interview with Jennifer Jacquet
(07/29/2010) "President Obama called it 'the worst environmental disaster America has ever faced.' So I thought I should face it and head to the Gulf"—these are the opening words on the popular blog Guilty Planet as the author, marine biologist Jennifer Jacquet, embarked on a ten day trip to Louisiana. As a scientist, Jacquet was, of course, interested in the impact of the some four million barrels of oil on the Gulf's already depleted ecosystem, however she was as equally keen to see how Louisianans were coping with the fossil fuel-disaster that devastated their most vital natural resource just four years after Hurricane Katrina.
Oil devastates indigenous tribes from the Amazon to the Gulf
(07/27/2010) For the past few months, the mainstream media has focused on the environmental and technical dimensions of the Gulf mess. While that’s certainly important, reporters have ignored a crucial aspect of the BP spill: cultural extermination and the plight of indigenous peoples. Recently, the issue was highlighted when Louisiana Gulf residents in the town of Dulac received some unfamiliar visitors: Cofán Indians and others from the Amazon jungle. What could have prompted these indigenous peoples to travel so far from their native South America? Victims of the criminal oil industry, the Cofán are cultural survivors. Intent on helping others avoid their own unfortunate fate, the Indians shared their experiences and insights with members of the United Houma Nation who have been wondering how they will ever preserve their way of life in the face of BP’s oil spill.
EU mandates biofuel environmental standards to protect forests, wetlands
(06/10/2010) The E.U. today moved to establish environmental standards for biofuels used in Europe, requiring biofuels to deliver "substantial reductions" in greenhouse gas emissions and not result in conversion of forests or wetlands, according to a statement from the European Commission.
Will we ever know the full wildlife toll of the BP oil spill?
(06/08/2010) Will we ever know the full wildlife toll of the BP oil spill? The short answer: no. The gruesome photos that are making the media rounds over the last week of oiled birds, fish, and crustaceans are according to experts only a small symbol of the ecological catastrophe that is likely occurring both in shallow and deep waters. Due to the photos, birds, especially the brown pelican, have become the symbol of the spill to date. But while dozens of birds have been brought to rescue stations covered in oil, the vast majority will die out at sea far from human eyes and snapping cameras, according to Sharon Taylor a vet with the US Fish and Wildlife Service.
Before the oil spill (photos)
(06/03/2010) With the BP oil spill continuing unabated into the 2010 Atlantic hurricane season, fears are rising that a major storm could dramatically worsen the impact of the disaster, which has already been called the worst in U.S. history. Forecasters are predicting 14 to 23 named storms this year, of which 3 to 7 will turn into major hurricanes. According to forecasters Philip Klotzbach and William Gray of Colorado State University, there is a 43 percent chance that Louisiana will be hit by a hurricane.
'No hope now remains' for the Alaotra grebe
(05/31/2010) World governments have missed their goal of stemming biodiversity loss by this year, instead biodiversity loss has worsened according to scientists and policy-makers, and a little rusty-colored bird, the Alaotra grebe (Tachybaptus rufolavatus) is perhaps a victim of this failure to prioritize biodiversity conservation. Native to a small region in Madagascar, the grebe has been declared extinct by BirdLife International and the IUCN Red List due to several factors including the introduction of invasive carnivorous fish and the use of nylon gill-nets by local fishermen, which now cover much of the bird's habitat, and are thought to have drowned diving grebes. The bird was also poached for food.
