Public gardens are the lungs of cities. Their structures vary according to the style of landscaping chosen for their design. In this study we have used the lichen biomonitoring with the IQA indices for the comparison between the two parts of the botanical garden of ElHamma in Algiers. Although this garden is located in the most polluted area of the Algiers bay, it still provides better air quality. French style part of the garden is characterized by open perpendicular alleys, while the other dance is somewhat similar to the English style. The results indicate that the second one has a superior quality and a greater specific richness of lichens.
