The relationship Sorger found was that areas with high levels of SO2 and NO2 had low to non-existent levels of tree lichen, whereas areas with low levels of SO2 and NO2 had higher levels of lichen and an overall better air quality. Thus, by simply monitoring tree lichen species (two to be exact) we will be able to get a good indication of the air quality in various parts of the city.
Interesting in getting involved but have no idea what lichen is or how to identify it? Not a problem! We plan to provide free and fun training to anyone interested in getting involved and who want to learn the skills. Please note: high school students are also encouraged to come out as we are able to sign off on volunteer hours.
Please join us for our next session as part of the Hamilton Centre for Teaching Peace's Edu-macation Mondays at the Sky Dragon centre!
