The ancient trees produced more wood over the past century than they have during any other time in their life, a stretch that dates back, in at least one case, a thousand years before the birth of Christ, according to a study released by the Redwoods and Climate Change Initiative.

The growth trend has actually accelerated over the past few decades, said the scientists from UC Berkeley and Humboldt State University who conducted the four-year study.

"It shows these trees are being impacted by something in the environment," said Emily Burns, director of science for Save the Redwoods League, the San Francisco nonprofit that is managing the initiative. That lengthens the growth season." The million study, funded by grants and donations, was the most intensive research project ever conducted on the giant trees.

The researchers climbed, poked and prodded 137 coast redwoods and giant sequoias on 16 research plots throughout the trees' geographic range.
