Colonists of limestone dry stone walls In Winsley, West Wiltshire

Lichens

Lichenological studies (the study of the structure, life characteristics and species composition of lichens) have become increasingly popular in recent years. According to the researchers of the descriptive essay writing service, the relevance of these processes is that in the presence or absence of groups of species of flowering or spore plants, fungi, especially lichens with similar sensitivity to atmospheric pollution, the degree of anthropogenic burden on the ecosystem can be determined. Therefore, below we have placed images with the rarest types of lichens.
