Sorbus hibernica, Irish whitebeam or fionn-choill, is a species native and endemic to Ireland. Its connection to the island is carried in its scientific name hibernica, Hibernia being the early Latin name for Ireland. It is a culturally important species, used as a symbol of royal authority and as a source of food for its edible fruits [1]. Both globally and regionally, the Irish whitebeam is a species vulnerable to extinction [2]. In Ireland in particular, surveys of the species suggest a population size of fewer than 1000 individuals [3]. It is also a species that is commonly researched globally, with more than 30 of its features being studied, as retrieved from relevant databases.
