In recent decades, wild boar numbers have increased worldwide. Wild boar can adapt to a wide range of habitats and foods and have the highest reproductive rate among ungulates. Therefore, wild boar can have a very substantial environmental impact and affect many ecosystem components. This paper summarises studies of the environmental impact of wild boar. Very few studies have quantified the impact of wild boar on plant and animal communities. Most of those studies indicate that wild boar can greatly affect species abundance, species richness. soil chemestry and food webs.
