How does the isolation of a small island environment shape the behavior and survival of both human inhabitants and local wildlife? Ronald M. Lockley, a naturalist and author, draws upon his extensive experience living on Skokholm Island to examine the ecological dynamics of a remote maritime habitat. He presents a detailed account of the symbiotic relationship between the island's geography and the species that occupy it, utilizing his observations to argue for the importance of undisturbed natural spaces.

Naturalists and historians frequently cite this work as a foundational text for understanding the ecological significance of small, isolated islands. Readers often note the descriptive, observational quality of the prose, which balances scientific inquiry with a personal narrative of solitude.
