Tree resprouting offers hope in former pastures of Brazil's cerrado

(09/06/2007) Deforested landscapes in the Brazilian cerrado show hopeful signs of recovery even after long periods of intensive use, reports a study published in the journal Biotropica. Analyzing the natural reestablishment of native trees in former pastureland located in the dry woodlands of the Brazilian cerrado, a team of researchers found that while species richness was lower in older pasture, density and composition of regenerating trees did not change with pasture age.


Brazil's threatened Atlantic forest may be more resilient than thought

(09/06/2007) The Atlantic forest of Brazil, one of the world's most threatened biodiversity hotspots, may have served as a critical refuge for biodiversity during the ice ages. The findings suggest that despite being reduced to just 8 percent of its original extent due to agriculture and urban expansion, the Atlantic forest may be capable of recovery. In other words, the Atlantic forest may be more resilient to change than previously believed.


Can remittances and globalization help the environment?

(09/05/2007) Globalization and other economic trends appear to be helping the degraded forests of El Salvador recover, reports new research that evaluated the impact of global trade, land policy changes, and remittances on forest cover. The study, by Susanna B. Hecht of University of California at Los Angeles and Sassan S. Saatchi of the California Institute of Technology, used socioeconomic data, land-use surveys, and satellite imagery to document significant increases in the area of El Salvador covered by both light woodlands and forest since peace accords were signed in the warn-torn country in 1992.

(06/08/2007) Deforestation rates fell by 89 percent in the Brazilian Amazon state of Mato Grosso for April 2007 compared with April 2006, according to the System Alert for Deforestation, an innovative deforestation monitoring program backed from Brazilian NGO Imazon. Mato Grosso, which has suffered some of the highest rates of deforestation of any state in the Brazilian Amazon, lost 2,268 square kilometers of forest between August 2006 and April 2007, a decline of 62 percent from the year earlier period when 5,968 square kilometers were cleared.


Dorothy Stang fought for social equity in the Amazon

(06/07/2007) Murder is not a pleasant place to start an article. Destruction of enormous amounts of virgin forest also does not help improve ones feelings and thoughts. Leaving out millions of people and talking about only the rights of thousands is pretty discouraging if you wish to be transparent, progressive and see a future for a beautiful country with enormous potential.


Can cattle ranchers and soy farmers save the Amazon?

(06/06/2007) John Cain Carter, a Texas rancher who moved to the heart of the Amazon 11 years ago and founded what is perhaps the most innovative organization working in the Amazon, Alianca da Terra, believes the only way to save the Amazon is through the market. Carter says that by giving producers incentives to reduce their impact on the forest, the market can succeed where conservation efforts have failed. What is most remarkable about Alianca's system is that it has the potential to be applied to any commodity anywhere in the world. That means palm oil in Borneo could be certified just as easily as sugar cane in Brazil or sheep in New Zealand. By addressing the supply chain, tracing agricultural products back to the specific fields where they were produced, the system offers perhaps the best market-based solution to combating deforestation. Combining these approaches with large-scale land conservation and scientific research offers what may be the best hope for saving the Amazon.


Unknown tribe found in the Amazon

(06/04/2007) An unknown Indian tribe has been discovered in the Amazon rainforest reports the Associated Press. The Metyktire tribe, with about 87 members, was found in late May around 1,200 northwest of Rio de Janeiro. Brazil's Federal Indian Bureau (FUNAI) says the tribe is a subgroup of the Kayapo tribe and lives on the Kayapos, 12.1-million-acre Menkregnoti Indian reservation.


Pictures of newly discovered species in Suriname

(06/04/2007) Scientists documented 467 species, including 24 species believed new to science, during a rainforest survey in eastern Suriname, South America. The expedition, led by conservation International (CI), was sponsored by two mining companies, BHP-Billiton Maatschappij Suriname (BMS) and Suriname Aluminium Company LLC (Suralco), hoping to mine the area for bauxite, the raw material used to make aluminum. conservation International said the Rapid Assessment Survey (RAP) will help "give miners guidance on protecting unique plants and animals during potential future development," according to a statement from the organization.


Polynesians brought chickens to Americas before Columbus

(06/04/2007) New DNS analysis shows that Polynesians introduced chickens to South America well before Christopher Columbus first set foot in the New World. The evidence supports the theory that the Americas were visited by sea-faring groups from the East prior to the arrival of Europeans. Using carbon dating and analysis DNA to determine the origin of chicken bones discovered at El Arenal, an archaeological site in Chile, a team of researchers led by Alice Storey of the University of Auckland found that the birds were descended from Polynesian stock and were introduced at least 100 years before the arrival of Europeans on the continent. The findings undermine claims that chickens were native to South America or that they were introduced by Spanish or Portuguese explorers.


Rural population decline may not slow deforestation

(06/03/2007) A new paper shoots down the theory that increasing urbanization will lead to increasing forest cover in the tropics. Writing in the July issue of the journal Biotropica, Sean Sloan, a researcher from McGill University in Montreal, argues that anticipated declines in rural populations via urbanization will not necessarily result in reforestation--a scenario put forth in a controversial paper published in Biotropica last year by Joseph Wright of the Smithsonian Tropical Research Institute in Panama and Helene Muller-Landau of the University of Minnesota. Wright and Muller-Landau said that deforestation rates will likely slow, then reverse, due to declining rural population density in developing countries.


Globalization could save the Amazon rainforest

(06/03/2007) The Amazon basin is home to the world's largest rainforest, an ecosystem that supports perhaps 30 percent of the world's terrestrial species, stores vast amounts of carbon, and exerts considerable influence on global weather patterns and climate. Few would dispute that it is one of the planet's most important landscapes. Despite its scale, the Amazon is also one of the fastest changing ecosystems, largely as a result of human activities, including deforestation, forest fires, and, increasingly, climate change. Few people understand these impacts better than Dr. Daniel Nepstad, one of the world's foremost experts on the Amazon rainforest. Now head of the Woods Hole Research Center's Amazon program in Belem, Brazil, Nepstad has spent more than 23 years in the Amazon, studying subjects ranging from forest fires and forest management policy to sustainable development. Nepstad says the Amazon is presently at a point unlike any he's ever seen, one where there are unparalleled risks and opportunities. While he's hopeful about some of the trends, he knows the Amazon faces difficult and immediate challenges.


Will Amazon drought worsen in 2007?

(05/29/2007) Contrary to popular belief, the Amazon rainforest is not rainy year round. Further from the equator, rainfall is more seasonal, with dry periods that sometimes last for months.


Extortion or global warming mitigation?

(05/24/2007) Marketwatch reported more details on Ecuador's proposal to forgo development of Amazonian oil fields in exchange for payments from industrialized nations. Last month Ecuadorian President Rafael Correa said that if the South American country is compensated with half of the forecasted lost revenues, it will not exploit oil in Yasuni National Park, setting aside the area for wildlife and indigenous people. Correa said the cost would be about $350 million per year.


Saving big cats depends on science, practical interventions

(05/21/2007) Big cats are some of Earth's largest and most threatened predators. Long persecuted as perceived threats to livestock and humans, hunted for their skins and purported medicinal values, and losing critical habitat to deforestation and conversion for agriculture, big cat populations have dwindled around the world for the past century. Given these trends, it should come as no surprise that big cats have become the focus of conservation efforts. Not only are large predators often the most vulnerable to human pressures and the first to disappear from ecosystems, but efforts to conserve them effectively help protect thousands of other species that share their habitat. At the forefront of these efforts in Dr. Luke Hunter, a biologist with the Wildlife conservation Society (WCS) where he heads their Great Cats Program. In a May 2007 interview with mongabay.com, Hunter discussed strategies for conserving carnivores and offered insight for students interested in pursuing careers in conservation science.
