Dendrology

Dendrology is the study and science of wooded plants. In this lab, we examined a pine tree from Georgia and a palm tree in Palm Springs. By counting the tree rings, you can mark important events that were happening in the world.

Elm Tree: By counting the tree rings, this tree is between 30 and 35 years old. After counting and measuring the rings and seeing the discrepancies in size I decided to look into why they were that way. It could be because of droughts and extreme heat or a lot of rain. the outer ones could be due to the saw being cut unevenly. There are many many many things that could attribute to the changes in the rings.

Pine Tree: By counting the tree rings, this tree was around 50-55 years old. This tree has very defined rings which means it probably had a healthy life and was a strong beautiful tree. although the edges are a little rough it could once again be because of a saw unevenly cutting.

Temperature:

now we will look at the climate conditions of the georgia pine and the California elm. this data goes all the way back to the 1960s and because the pine is older than the elm there is more data for it. This chart is looking at the temperatures of the state and the thickness of the tree rings

With this information, we can graph the data to deduct if there is a correlation between the rings thickness and their temperatures.

From this graph, we may conclude that there is a huge difference in temperatures between the two trees, obviously since they are located in two different climate conditions. However, there is not too much difference in their ring thickness, meaning temperature must not be a crucial factor in determining what gives tree rings their characteristics.

Below is a chart of comparing tree thickness to precipitation to see if there may be a correlation there.

Now, a graph will be made from this data to visually illustrate a correlation.

It is still apparent that there are differences in precipitation based on location of the two trees, but there is still no correlation with the tree rings' characteristics. Therefore, the tree rings may have their characteristics based on other climate conditions.

It is an interesting concept to ponder on what events have happened while the tree has been a live. Here are a few events that have happened during both trees lives.
