## How can you tell the age of a tree by its ring?

Count the dark rings to calculate the age of the tree. Start in the middle of the stump or cross-section of wood and count the first dark ring you see. Continue counting outwards from the middle ring until you reach the last dark ring. The total number of dark rings represents the age of the tree in years.

## Do tree rings represent years?

One light ring plus one dark ring equals one year of the trees life. Because trees are sensitive to local climate conditions, such as rain and temperature, they give scientists some information about that areas local climate in the past.

## How can you estimate the age of a tree?

## What are the limitations to tree rings?

Limitations. Along with the advantages of dendroclimatology are some limitations: confounding factors, geographic coverage, annular resolution, and collection difficulties. The field has developed various methods to partially adjust for these challenges.

## What is the lifespan of trees?

Under favourable conditions some specimens live five to seven years. The woody seed plants, such as conifers and broadleaf trees, are the most amenable to determination of age.
