The basis of the science lies in a tree's unique pattern of growth rings, which acts as a kind of fingerprint. Every year a new ring is added to a tree's trunk and branches, just beneath the bark.

Researchers believe they have identified a network of spies to help combat illegal gold mining operations in the Amazon ...

(See Create a DNA Fingerprint.) Every year a new ring of growth is added to a tree's trunk and branches, just beneath the bark. The thickness of this ring depends on how much the tree grows during ...

Climate change has significantly reduced snow cover, affecting caribou herds and hydroelectric forecasts, study shows.

Quebec tree rings dating back nearly 200 years indicate snowpack in the Gaspésie mountains has declined considerably in ...

But after months of short-term drought across Arizona, the stream gently rippled by on a February outing. The water level was ...

But few people know that the rings in trees can tell us much more than just a tree’s age. And perhaps even fewer know that there is a field of science dedicated to the study of tree rings.

After carefully counting each ring of the tree, paleobotanist Scott Wing determined that the tree lived for 260 years, although he admits that may not be exactly correct. Each ring on the sequoia ...

A study of tree rings in the Gaspésie’s Sainte-Anne River area reveals that snowpacks have been declining noticeably in the ...

Quebec tree rings dating back nearly 200 years indicate snowpack in the Gaspésie mountains has declined considerably in recent decades, Concordia University researchers suggest in a study that ...

Tree rings in the region can be a natural indicator of snow melt: thinner rings are associated with springs that have a late-staying snow cover, thicker rings with years of early thaw.
