Bryophytes, which include mosses, liverworts, and hornworts, are present in most terrestrial ecosystems and are especially dominant in cold climates. Isla de los Estados has been an important site for bryophyte collection since the late eighteenth century, with contributions from notable botanists such as Menzies, Skottsberg, Castellanos, and Matteri. Although a considerable portion of the collected specimens has been identified and published, many remain undetermined and dispersed across various herbaria, making it difficult to produce a comprehensive species list. This study aims to provide a preliminary list of moss species from the island by reviewing historical collections, databases, and herbarium records. A total of 765 records were compiled, identifying 66 species across 37 families and 36 genera, along with 30 additional genera identified to that level. This work represents an initial step toward documenting the bryophyte diversity of Isla de los Estados.
