Most tree species are reliable; oak is the most reliable tree type for tree rings - with not a single known case of a missing annual growth ring.

Due to the sweeping and diverse applications of this data, specialists can come from many academic disciplines.

There are no degrees in dendrochronology because though it is useful across the board, the method itself is fairly limited.

In each growth season, trees create a new ring that reflects the weather conditions of that growth season.

On its own, a single record can tell us only a little about the environmental conditions of the time in a specific year of the growth of the tree, and of course the age of the tree at felling, but when we put hundreds and thousands of tree-ring records together, it can tell us a lot more.
