For most people, taking care of the front yard means cutting the grass every few weeks.

But for Bill Massengale, lawn care involves looking after the lofty California coastal redwood growing in the front yard of his law office on Columbia Street.

“When we bought the place we were told that the only thing we had to do was to make sure nothing happens to the redwood,” Massengale says. “It’s one of my chief duties in life."

Officials with Duke Energy have decided to hold off on a program that would have used a chemical product, Cambistat, to slow the growth of trees near power lines.

Officials with Duke Energy have decided to hold off on a program that would have used a chemical product, Cambistat, to slow the growth of trees near power lines. The utility planned to inject the application into the soil around trees.  The application would slow growth, reduce how often trees near power lines needed to be trimmed, and save money. But residents questioned the risks, and complained that they were being forced into the program.

Researchers at Duke University have found evidence that climate change is shortening the life cycles of trees in the U.S.

Research in tropical areas like Peru has suggested that trees are migrating to cooler areas by producing offspring in higher elevations or latitudes, but the latest study says most plants in the U.S. might not be able to move quickly enough to keep up with rising temperatures.

Rising Temps Tough on Some Trees

A new study from Duke University points to tough times ahead for some tree species. Researchers examined data on climate change and the effect rising temperatures are having on tree populations in the eastern U.S. James Clark is a professor of biology and statistics at Duke. He says models that predicted trees would move with the climate were wrong.
