Green Council look at our school air quality by studying trees!

Today, we had a special visitor to Green Council.
Bike it Ray came with a lot of interesting chart about different animals, poo, and lichens.  He told us that lichens grow on trees and bricks and can tell us a lot about the air quality in our area.

We went for a nature walk to see what we would find in the bottom playground. We were very excited to see lichen on the trees and Bike It Rays said that although there is more to do, the lichens we saw were a healthy green colour and indicate that our air quality is not bad for our infants.  Hooray!

Here we are studying a tree. Do you know what type of tree it is? (clue: the colour is silver!)
