  • what are the sampling techniques you will use?   

           We’re using a Lichen Grid tester. This captures the relative amount of lichen of each tree. You can make the grid by forming wire into four 10x10 squares.To measure the lichen you hold the grid up to the southside of the tree and record the lichen inside each quadrant on the tree. There are four different classifications of the amount of lichen you may see. If you see no lichen, the score is zero. If there are 1 to 2 cm of lichen the score is 1. If there are several small colonies of lichen, the score is 2. If lichen covers more than 10 percent of the grid square, the score is 3. Once you have the score from each lichen square you add each score up and divide by the number of grid squares, which is 4. A perfect score (which means good air quality) is 3. The lowest score is a 0. Might want to throw on a gas mask. This method is based off the following website: http://www.goodneighbourcampaigns.ca/resources/resources-community1408-2/tree-lichen-monitoring

 

Variables and Methods.

  • how often will you collect data?

         If ever we’re in a new neighborhood, we will try to get a sample of the lichen amounts

 

  • where will you collect data?

Different neighborhoods around the city of Chicago.
