Trees
Trees create breathable, clean air, provide animals shelter, and offer us shade on a sunny day. A common part of our daily landscape, trees are often overlooked. Let's slow down and get to know a tree.
Challenge: Pick a Special Tree
It could be near your sit spot or somewhere new. It could be a coniferous or deciduous tree.
Look at all parts of your tree closely
around the base and the roots
at the trunk
high up into the branches.
Challenge: Document Your Tree Observations
Make detailed observations of your tree in your nature journal.
Draw your tree from different perspectives: from a high place, underneath looking up, or from a distance.
Based on your observations, write a list of 10 words to describe your tree. Use those words in a paragraph or poem.
Tree Buds

Tree Bark
Go outside and find 2-5 trees with different bark.
Write down your observations of each tree and do a bark rubbing.

Looking for Lichen
Lichen is a plant-like organism that grows on trees and rocks. Over 750 species of lichen live in Minnesota and come in a variety of colors like green, yellow, orange, red, and white. Lichen is easy to spot on trees, but don’t worry, the lichen is not hurting the tree, it just lives on top of the bark.
What is lichen?
Lichen is a combination of fungus and algae. The fungus creates the structure and the algae produces the food and together they live as lichen. This is a symbiotic relationship because the fungus and algae need each other to live.
Why is lichen important?
Lichen love clean air and die quickly if there is high air pollution. Scientists use lichen as a bioindicator to determine the air quality of an area. This means if there is lichen on trees, the air quality in that area is good.
3 Main Types of Lichen
Crustose- crusty and flat. Usually red, yellow and orange in color.
Foliose- leaf-like in shape with thin roots to anchor them
Fruticose- bushy, looks like miniature shrubs
Challenge: Lichen Hunting!
Now head outside and look for lichen. It can grow in unexpected places- like on this old clothesline.
