No place for old trees (J. A. Lutz)
The oldest and largest trees within California's world famous Yosemite National Park are disappearing.
Climate change appears to be a major cause of the loss.
The revelation comes from an analysis of data collected over 60 years by forest ecologists.
They say one worrying aspect of the decline is that it is happening within one of most protected forests within the US, suggesting that even more large trees may be dying off elsewhere."
