Lichens are well-known sentinels of problems with air quality. This project uses locally collected field data on lichen presence & abundance to better understand how lichens respond to changes. Navigation skills with a hand held compass are developed. Students collect data from 5 trees at their site, and write navigation instructions so the next team can find the same trees. Students download apps to their phone to use in the field. Students and instructors will explore and gain experience with statistical analyses, and field data collection as part of this project. This project can be the subject of a course laboratory activity lasting between 1 and 3 weeks.
