Skerries Lichen

During the course of our project, we at Ardgillan C.C and Skerries C.C discovered that the lichen found in Skerries tend to be more green and white than orange and red.

This tells us that Skerries is a not very polluted town. The green lichen can only grow when there are low levels of pollution in the air. The lichen that we found in Skerries were mainly green and we searched mainly for lichen on trees.

Skerries has low levels of pollution because they have a relatively small population. There are no factories in Skerries so they don't produce many fumes. Skerries is a fairly small town so people can walk to places so there is not a lot of pollution from cars.
