The following pictures show lichens growing on tree stumps or trunks. They are all nitrogen tolerant which means that they can grow where the levels of air pollution are quite high. This is to be expected because of the main road running along the West side of the park. The Yellowish one is Xanthoria, the one with black spots is Lecidella, the grey green crusty one is Flavoparmelia, the one with greenish spikes is Cladonia and the dusty grey one is Lepraria.
