A study shows that the worlds biggest trees are dying quickly in forests at all latitudes ... from California to Sweden to Australia. Yosemite National Park, African savannahs, Amazon rainforests, and northern arboreal forests are all affected.
"A report by three of the world’s leading ecologists in today’s issue of the journal Science warns of an alarming increase in deathrates among trees 100-300 years old" (SciNews)
"Large old trees play critical ecological roles. They provide nesting or sheltering cavities for up to 30% of all birds and animals in some ecosystems. They store huge amounts of carbon. They recycle soil nutrients, create rich patches for other life to thrive in, and influence the flow of water within landscapes and the local climate."
(Professor Bill Lawrence, James Cook University)
