- Climate change is giving old trees a growth spurt - Larch trees in the permafrost forests of northeastern China -- the northernmost tree species on Earth -- are growing faster as a result of climate change. A new study of growth rings from Dahurian larch in China's northern forests finds the hardy trees grew more from 2005 to 2014 than in the preceding 40 years.
- Oldest known trees in eastern North America documented - A stand of bald cypress trees in North Carolina, including one least 2,624 years old, are the oldest known living trees in eastern North America and the oldest wetland tree species in the world. They show evidence of severe flooding and drought during colonial and pre-colonial times.
- Non-native invasive insects, diseases decreasing carbon stored in US forests - Scientists have found that non-native invasive insects and diseases are reducing the amount of carbon stored in trees across the United States.
