Skyline Interns Map the Trees!

For the last couple meetings, the Skyline Interns have practiced their data collection skills by creating an inventory of the trees on their school campus.

The students measured the diameter of trees, recording the GPS coordinates, identified the species, and took a picture of the tree. This data can be used to track the number, growth rate, and health of trees in an specified area. It can also help determine when and where to add more trees to an area. Soon the students will use this tree data to calculate the amount of carbon the trees are sequestering as part of their air quality initiative.

The skill of accurately recording and organizing data extends beyond just collecting data on trees. It is a valuable skill that applies across scientific fields and other non science specific disciplines.

The Interns will soon be able to use their data collection experience in a few upcoming projects to help local governments collect data on their trees.

Skyline Interns Draw The Trees

The Skyline interns practiced their finest field sketches of the large and various trees on their campus. Drawing trees helps focus on the small details, and can help reveal subtle differences among tree parts to aid in identifying different tree species. For example, while the carbo tree has an ordinary oval shaped leaf, the interns noticed that the leaves have a small indent on their tip.

Students are practicing their tree identification skills in preparation for making a tree inventory on their campus, and collecting data for some local government. A tree inventory is a collection of tree information, and the tree species is one of the important criteria.
