Why is human activity restricted on Sursey Island?

Human activity is restricted on Sursey Island primarily to protect its unique ecosystem and facilitate scientific research. The island, formed by volcanic activity in 1967, serves as an important natural laboratory for studying colonization and ecological succession. Restrictions help prevent disturbances that could disrupt the delicate balance of species and habitats that have developed there. Access is limited to researchers and conservationists, ensuring the preservation of its pristine environment.
