(03/20/2013) For a long time male lions were derided as the lazy ones in the pride, depending on females for the bulk of hunting and not pulling their weight. Much of this was based on field observations—female lions hunt cooperatively, often in open savannah, and therefore are easier to track at night. But new research in Animal Behaviour is showing that males are adroit hunters in their own right, except prickly males hunt alone and use dense vegetation as cover; instead of social hunting in open savannah, they depend on ambushing unsuspecting prey.
Featured video: Saving the Amazon through maps
(02/20/2013) In a new video ethnobotanist, Mark Plotkin, talks about recent—and historical—efforts to preserve the Amazon rainforest through map-making and technology. Today scientists like Plotkin are teaching indigenous people how to digitally map their territory to win land rights over the forest they've used for centuries.
New forest map shows 6% of Amazon deforested between 2000 and 2010
(09/21/2012) An update to one of the most comprehensive maps of the Amazon basin shows that forest cover across the world's largest rainforest declined by about six percent between 2000 and 2010. But the map also reveals hopeful signs that recognition of protected areas and native lands across the eight countries and one department that make up the Amazon is improving, with conservation and indigenous territories now covering nearly half of its land mass.
3-D laser mapping shows elephants have big impact on trees
(08/06/2012) Scientists have long known that African elephants (Loxodonta africana) are talented tree-topplers, able to take down even large trees in order to gobble out-of-reach leaves. However the extent of his behavior across a large area has been difficult to quantify. But a new study in Ecology Letters has used a bird's-eye view—with 3-D—of Kruger National Park in South Africa to determine the impact of elephants on trees.
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.
Google brings Street View, Maps to the Amazon (photos)
(03/22/2012) Google has posted images of a stretch of rainforest and communities along the Amazon river on its Street View product available via Google Maps. The addition makes it possible to virtually explore communities and ecosystems in Earth's largest tropical forest.
Model airplane used to monitor rainforests - conservation drones take flight
(02/23/2012) Conservationists have converted a remote-controlled plane into a potent tool for conservation. Using seed funding from the National Geographic Society, The Orangutan Conservancy, and the Denver Zoo, Lian Pin Koh, an ecologist at the ETH Zürich, and Serge Wich, a biologist at the University of Zürich and PanEco, have developed a conservation drone equipped with cameras, sensors and GPS. So far they have used the remote-controlled aircraft to map deforestation, count orangutans and other endangered species, and get a bird's eye view of hard-to-access forest areas in North Sumatra, Indonesia.
Guyanese tribe maps Connecticut-sized rainforest for land rights
(02/07/2012) In a bid to gain legal recognition of their land, the indigenous Wapichan people have digitally mapped their customary rainforest land in Guyana over the past ten years. Covering 1.4 million hectares, about the size of Connecticut, the rainforest would be split between sustainable-use regions, sacred areas, and wildlife conservation according to a plan by the Wapichan tribe that will be released today. The plan says the tribe would preserve the forest from extractive industries.
Rainforests store 229 billion tons of carbon globally finds new 'wall-to-wall' carbon map
(01/30/2012) Tropical rainforests store some 229 billion tons of carbon in their vegetation — about 20 percent more than previously estimated — finds a new satellite-based assessment published in the journal Nature Climate Change. The findings could help improve the accuracy of reporting CO2 emissions reductions under the proposed REDD program, which aims to compensate tropical countries for cutting deforestation, forest degradation, and peatlands destruction.
Global map of REDD+ projects released
(12/03/2011) The Center for International Forestry Research (CIFOR) on Saturday released a comprehensive map of the world's REDD+ programs. The map includes 340 REDD+ projects, programs, and policies in 52 countries.
Community mapping of African rainforests could show way forward for preservation, REDD
(12/01/2011) A new initiative to place community mapping of central African rainforests online could prove key to local rights in the region, says the UK-based NGO Rainforest Foundation. Working with forest communities in five African countries, Rainforest Foundation has helped create digital maps of local forests, including use areas, parks, and threats such as logging and mining. The website, MappingForRights.org, includes interactive maps, photos, and video.
New global carbon map for 2.5 billion ha of forests
(05/31/2011) Tropical forests across Latin America, Africa, and Southeast Asia stored 247 gigatons of carbon — more than 30 years' worth of current emissions from fossil fuels use — in the early 2000s, according to a comprehensive assessment of the world's carbon stocks. The research, published in the journal Proceedings of the National Academy of Sciences by an international team of scientists, used data from 4,079 plot sites around the world and satellite-based measurements to estimate that forests store 193 billion tons of carbon in their vegetation and 54 billion tons in their roots structure. The study has produced a carbon map for 2.5 billion ha (6.2 billion acres) of forests.
Forest carbon map released for the US
(04/20/2011) The Woods Hole Research Center (WHRC) has released the first hectare-scale map displaying aboveground woody biomass and forest carbon in US forests. The map, which also shows canopy heights, is known as the National Biomass and Carbon Dataset (NBCD).
Indigenous peoples of Congo map their forests with GPS in an effort to save them
(04/13/2008) This week over five hundred villagers in the Democratic Republic of Congo's rainforest will employ GPS technology to map their forests in an effort to preserve their territory from logging companies.
