Eastern US forests more vulnerable to drought than before 1800s

ScienceDaily: Over thousands of years, most forests in the eastern United States evolved with frequent fire, which promoted tree species and ecosystems that were both fire and drought resistant. In little more than a century, humans upset that balance, suggest researchers, who blame the change, in part, on the well-meaning efforts of Smokey Bear. Since the 1930s, the composition of forests in the region has changed markedly, according to Marc Abrams, professor of forest ecology and physiology at Penn State. Drought-sensitive,...

New insights into the seasonality of Amazon's evergreen forests

EurekAlert: Sometimes you can't see the forest for the trees. In the Amazon, the opposite is true: without truly seeing the trees, you can't "see" the forest and understand the seasonal patterns of photosynthesis that play a major role in ecosystem and climate models, according to new research funded by the National Science Foundation (NSF). "We can't understand the forest unless we understand the individual details," said Scott Saleska, associate professor of ecology and evolutionary biology at the University...

Reuters: Bare-chested, Alan Siyampondo shovels soil onto a smoking kiln stuffed with burning teak wood to produce a batch of charcoal in the heart of Dambwa Forest Reserve outside Livingstone. Nearby in the savannah woodland close to Zambia's southern border, another man prepares to turn his chopped logs into charcoal. Despite concerted efforts to reduce deforestation, this season's poor rainfall - influenced by the El Nio weather phenomenon is causing food and power shortages that could force more Zambian...
Aerial vision captures bushfire devastation of Tasmania's world heritage-listed forests

Guardian: Footage shows the extent of the destruction caused by bushfires in the Australian states world heritage-listed wilderness. Unlike the countrys eucalyptus forests, which use fire to regenerate, these plants have not evolved to live within the cycle of conflagration and renewal. If they are burned, they die

Study: All US Forests From Coast To Coast Now Threatened Climate Change, Drought
2016-02-23 06:52:00| Climate Ark Climate Change & Global Warming Newsfeed
Inquistr: In as little as 20 years, forests in the U.S. may look very different than they do today. A new study is warning that climate change and drought will likely threaten all of the countrys trees. The effects on the American West have already proven disastrous, but a new study that compiles hundreds of smaller studies on the health of U.S. forests and rangelands has suggested that the problem will spread east, the Christian Science Monitor reported. Science is currently scrambling to understand the...
