"Mighty Old Trees Are Perishing Fast, Study Warns"
"The death rate of many of the biggest and oldest trees around the world is increasing rapidly, scientists report in a new study in Friday’s issue of the journal Science. They warned that research to understand and stem the loss of the trees is urgently needed."
"'It’s a worldwide problem and appears to be happening in most types of forest,' said the study’s lead author, David Lindemayer, a professor at Australian National University and an expert in landscape ecology and forest management.
The research team found that big, old trees are dying at an alarmingly fast clip around the world at all latitudes – Yosemite National Park in California, the African savanna, the Brazilian rain forest, Europe and the boreal forests around the world. "Source: Green/NYT, 12/10/2012
