Death Rate of Forests Doubles, Scientists Find
EcoSalon — ... The scientists, operating with the U.S. Geological Survey, monitored trees for generations, carefully counting them by hand. They found that the death rate of trees increased across species and was not related to other factors, such as normal forest growth patterns, fire suppression, or pollution. Pines do appear to be the most sensitive, however. Equally troubling is the fact that it appears these dying trees release more carbon than they absorb. ...

Trees in Western U.S.Dying at Faster Rate in Recent Decades
Yale Environment 360 — Trees in western U.S. forests are dying twice as fast as 20 to 30 years ago because of rising temperatures, drought, and major insect infestations sparked by these changing conditions, according to a new study. The study, overseen by the U.S. Geological Survey and published in the journal Science, looked at changes in 76 forest plots that have been monitored for years and found that regardless of region, tree species, or elevation, forests are losing trees at an accelerated rate. The team of 11 researchers said the quickening pace of forest ...
