Reforestation a growing, but complicated, initiative
(06/12/2008) As the rate of deforestation continues apace — 13 million hectares per year in a global basis — several countries have begun to look at reforesting degraded areas to aid suffering biodiversity, indigenous groups, and small local economies. However most of the interest and activity surrounding reforestation is as a tool to mitigate climate change. A new program just launched by the Nature Conservancy and several local partners plans to plant a billion trees in the fragmented Atlantic Forest of Brazil. The United Nations Environmental Program has already planted over two billion trees worldwide and plans to plant five billion more. China has planted billions more. However effective reforestation is not proving as easy as simply planting trees and waiting for them to grow, in fact, sometimes it may be best to leave the whole process to nature.
New discoveries about past forest changes may help predict future ones in a changing climate
(06/12/2008) There is no better method to understand the future than to look to the past. Several new studies of the earth's glacial history are transforming the way scientists look at tree behvaior during extreme changes in climate. Scientists Remj Petit, Feng Sheng Hu, and Christopher Dick described such changes in relation to current global warming in the new issue of the journal Science. They report that already "in some parts of the world, tree species have started to shift their distributions in response to anthropogenic climatic warming", thus raising the stakes for understanding how tree species will adapt to coming changes.
REDD could trigger bias in conservation funding towards carbon-rich ecosystems
(06/12/2008) The Reducing Emissions from Deforestation and Degradation (REDD) mechanism proposed as a means to fight global warming and protect forests may leave some ecosystems at risk to development argue researchers in an editorial published in the journal Science.
Forestry will play a critical role in slowing global warming
(06/12/2008) While reducing deforestation and forest degradation would pay great dividends in the fight against global climate change by eliminating up to a fifth of greenhouse gas emissions, other mechanisms can also enhance the capacity of forests to sequester carbon from the atmosphere, show researchers writing in this week's issue of the journal Science.

Forests face governance challenges
(06/12/2008) Governments "own" about 86 percent of the word's forests, but recent changes in forest management structure means they effectively control far less than they did just a generation ago. As such, the fate of forests is increasingly determined by concesssionary agreements with extractive industries and the whims of market demand for commodities produced on forest lands. Climate change and rapid economic growth are poised to further complicate effective management of forest areas.

Colombia creates rainforest reserve to protect medicinal plants
(06/11/2008) Colombia today announced the creation of a rainforest reserve dedicated to the protection of medicinal plants. The Orito Ingi-Ande Medicinal Flora Sanctuary encompasses 10,626 hectares of biologically-rich tropical rainforest ranging in altitude from 700 to 3300 meters above sea level. The sanctuary is based on an initiative launched by local indigenous communities with the support of the Amazon conservation Team (ACT), an innovative NGO working with native peoples to conserve biodiversity, health, and culture in South American rainforests. Members of the communities — which include the Kofán, Inga, Siona, Kamtsá, and Coreguaje tribes — combined their rich knowledge of medicinal plants with cutting-edge technology to determine the placement and extent of the reserve. Their contributions to the effort are reflected in the name of the reserve, according to ACT.

Argentina's primates under threat from agriculture
(06/09/2008) Five species of non-human primates inhabit in northern Argentina: black and gold howlers, brown howlers, black capuchins, brown-capped capuchins, and owl monkeys. Although two of these species are clearly endangered (brown howlers and owl monkeys), populations of all other species are disappearing due to anthropogenic changes of their habitats. Most of the forests where these species inhabit are under continuous alteration and degradation due to soy, rice, and forest plantations, and exotic pastures for livestock. Moreover, protected forests in Argentina are insufficient to protect these primates.
Tropical dry evergreen forests in India protected by religious and cultural beliefs
(06/09/2008) Tropical dry evergreen forest has restricted global distribution — limited to parts of Asia (on the Coromandel coast of India, northern Sri Lanka, Vietnam, Thailand), Africa and Central America — but is highly variable in terms of height and the species it contains, depending on site location, soil type and the level of human impacts. A new study, published in the June issue of Tropical conservation Science by N. Parthasarathy and colleagues, looks at tropical dry evergreen forest on the Coromandel coast of India where the ecosystem occurs both in patches and as sacred groves or temple forests protected by the local people on religious grounds.
Mexican canyon serves as key refuge for endangered spider monkeys

Dung beetles persist in long-term forest fragments but may suffer from hunting of large animals
(06/09/2008) Dung beetles bury animal dung to use as their own food and to provide food for their young. This group of beetles is especially prevalent in tropical rainforests. Their burying behvaior incidentally contributes to ecosystem functioning and health by the removal of waste, control of dung-breeding pests, soil fertilization and aeration, and the secondary burial of intact seeds found in mammal feces. Because of their important roles in ecosystems, it is important to know how they are affected by habitat change, in this case, habitat fragmentation.
Biodiversity data gap impedes research and conservation efforts
(06/09/2008) Biodiversity loss is occurring at an alarming rate around the world. Species are found in the greatest numbers in the tropics and as these areas are impacted by an increasing intensity of human pressure, the status of animal and plant life within them is in many cases in severe decline. International legislation, such as the 2010 Target of the Convention on Biological Diversity, requires countries to measure trends in biodiversity, and also monitor progress towards lowering the rate of biodiversity loss.
Rare golden primates help speed recovery of endangered Brazilian forest
(06/09/2008) The endangered golden lion tamarin — a flagship species for conservation efforts in Brazil's highly threatened Atlantic Forest or Mata Atlantica — plays an important role in seed dispersal, thereby helping forest regeneration, according to research published in the June issue of the open access e-journal Tropical conservation Science.

Amazon beef producer creates eco-certified meat product with help of scientists
(06/08/2008) Independencia Alimentos SA, Brazil's fifth-largest beef producer, will create an "eco-certified", branded beef product from the Amazon's Xingu region. Certification will be based on criteria established by Alian?a da Terra, an Brazilian NGO that seeks to improve the environmental performance of ranchers and beef producers in the world's largest rainforest. The new beef product will include a per-kilo "ecosystem service fee" — calculated with the help of scientists at the Woods Hole Research Center — to facilitate a financial reward for the producer's environmental stewardship.
Big Farms Can Make the Leap to Organic Farming, Study Suggests
(06/04/2008) Large fruit and vegetable growers can adopt the methods of small-scale organic farms while maintaining crop yields, keeping pests in check, and improving the health of their soil, researchers report in the July 2008 issue of Agriculture, Ecosystems and Environment.
Scientists aim to catalogue tropical island from mountaintops to seafloor
(06/04/2008) Scientists are launching an effort to catalogue a complete tropical ecosystem, the first time anyone has attempted such an ambitious undertaking. Led by researchers at the University of California, Berkeley, a U.S.-French team plans to collect DNA "barcodes" for every animal, plant, and fungus on the small island of Moorea in the South Pacific, scouring habitats from coral reefs to high-reaching cloud forests. The island could eventually serve as a model for how ecosystems respond to stresses such as climate change, invasive species, and pollution.
Diversity in streams may brace Chinook salmon for climate change
(06/03/2008) Chinook salmon face a one-two punch. They have disappeared from several rivers in the western U.S. largely because of human interventions and some populations are threatened or endangered. Numbers of Chinook in California's Central Valley have dwindled by 88 percent in the past five years, a loss that closed fisheries for 2008 and may cost California's economy $167 million, according to the state Department of Fish and Game. On top of all this looms a second impact: These salmon will be in hotter water still because of climate change.
Brazil's new environmental minister blames ranchers for surge in Amazon deforestation
(06/03/2008) Deforestation in the Brazilian Amazon rose significantly in April 2008 according to Carlos Minc, Brazil's newly appointed environment minister.
Food miles are less important to environment than food choices, study concludes
(06/02/2008) Shoppers concerned about the environment should not place "buying local" at the top of their list of priorities when purchasing food, according to a study published online on April 16 in the journal Environmental Science & Technology. The fuel burned in transporting food items from farm to marketplace creates just a small percentage of the total greenhouse gas emissions associated with the food. Instead, consumers should shift their diets to include more foods that require less energy to produce in the first place.
Papua New Guinea's rainforests disappearing faster than thought
(06/02/2008) Logging is taking a heavy toll on the forests of Papua New Guinea, suggests a new study. Using satellite images to reveal changes in forest cover between 1972 and 2002, researchers from the University of Papua New Guinea and the Australian National University found that Papua New Guinea (PNG) lost more than 5 million hectares of forest over the past three decades — total forest cover declined from 38 million hectares in 1972 to 33 million hectares in 2002. Worse, deforestation rates may be accelerating, with the pace of forest clearing reaching 362,000 hectares (895,000 acres) per year in 2001. The study warns that at current rates 53 percent of the country's forests could be lost or seriously degraded by 2021.
Cellulosic biofuels may be viable alternative to gas within 5 years
(06/02/2008) A new institute in the San Francisco Bay Area is seeking to make cellulosic biofuel an economically viable alternative to corn ethanol and gasoline within the next five years. The Joint BioEnergy Institute (JBEI), a partnership between three national laboratories and three Bay Area universities, was formed in June 2007 after the U.S. Department of Energy awarded the institute a $125 million grant to develop better methods for making liquid biofuels from the natural cellulose in trees and grasses. JBEI researchers expect cellulosic biofuels to yield more energy, produce less greenhouse gases, and have less impact on the environment than other alternatives to gasoline, such as corn ethanol.
