Remembrance of Lost Species Day (November 30) is a time to honor the species that have gone extinct, especially in modern times, or are facing extinction. It is also a day to reflect on the roles we (humans) play in driving species imperilment and the responsibility we have to prevent further extinction. In honor of extinct and imperiled species, the Journal of Lost Species (JLS) is a new, peer-reviewed record of the contemporary biodiversity crisis. The goals of JLS are to advance scientific understanding of extinction, support the development of methods for biodiversity documentation, and facilitate the rediscovery of lost species. Publications in JLS include the documentation of imperiled, lost, and extinct species, as well as notes on rediscovery. Lost species are defined as species that have not been detected in the wild in ten or more years, and lost species might be extinct, imperiled, or even stable and simply difficult to detect or insufficiently searched for. This particular use of the word "lost" is important, because it reminds us that even species that have not been seen in many years might be found again. JLS is true open access: free for authors and readers. Our partners include Re:wild, the IUCN Species Survival Commission, the University of Nevada Museum of Natural History, and the Tahoe Institute for Global Sustainability. Our Editorial Board members span the globe and provide expertise across the tree of life. Our contributors and audience extend beyond academic scientists: JLS invites contributions from land managers, conservation practitioners, amateur naturalists, and community scientists. JLS is currently accepting submissions for the first issue. To learn more about article types and the submission process, visit journaloflostspecies.org.
