Unexpectedly Intriguing!

How can you tell how old a tree is without chopping it down and counting its rings?

It turns out that there's some really simple math that you can use to estimate the age of a tree. All you need to know is how big around its trunk is and what kind of tree it is!

Here at Political Calculations, we build tools to solve problems like this! And, after a quick Internet search, we discovered that no one else appears to have already built a tool to solve this kind of math, which means that we'll have a monopoly on tree age calculators on the World Wide Web! Can fame and riches be far behind? Or an intensive investigation by the anti-trust division of the Department of Justice?

Bring it on, we say! Now, let's get to business....

In our tool, enter the circumference of the tree you measured and select which kind of tree it is from our list (if it's not in the list, select a tree that you believe would have a similar growth factor). Then click the "Calculate" button, and we'll give you a pretty good estimate of the age of that tree!

Arboriculturist Jim Skiera offers the following insight for interpreting the results of the math:

"The figures in the chart are taken for forest grown trees. In a landscape setting, where trees are being provided additional care, these figures probably would need to be adjusted to get an accurate estimate. Growth has to do with the location of the tree and the type of care it has received. Trees in the landscape tend to grow faster and develop wider growth rings more quickly because the competition from other trees is usually less and the additional water and fertilizer that is provided by the home owner will also increase growth.

In other words, you need to take into account where the tree you've measured is located. If the tree whose age you're trying to estimate is in your yard or in a park, and not in a forest, our tool will overestimate the age of the tree.

Now for the really cool part. What we've just done for estimating the age of trees, we can do with people too! We'll explain more soon....
