The black discoloration on tree trunks could be due to several factors, including the presence of fungal infections, such as black sooty mold, which can develop from insect excretions like honeydew. It might also indicate a problem with bark health, such as cankers or rot. Additionally, environmental factors like pollution or physical damage could lead to blackened areas. It's a good idea to inspect the trees closely and consider consulting an arborist for a proper diagnosis and treatment.
