2015, San Andres de Giles, Buenos Aires, Argentina

lichensThe focus of this project is to analyze the population of lichens found in trees within different areas of San Antonio de Giles town. The study of these lichens is important because they can be indicators of the quality of the air we are breathing. In order to define a parameter, the students plan to analyze the presence, or absence, of lichens in different parts of town. They also proposed an investigation on the density of the population of lichens and the analysis of the different types of lichens found. This analysis takes into account their color, appearance and the lichen’s grouping/type (foliose, fruticose, crustose). By analyzing the lichens the students are able to check and/or refute their hypothesis about the feasibility of solely using this method to monitor the quality of the air we breathe.
