The Belfast Naturalists' Field Club is a club of naturalists based in Belfast, Northern Ireland. Founded in 1863, the club was an important part of the education system for Victorian naturalists and worked largely through first-hand field studies.[1] It has been credited with playing an important role in the elucidation of glacial and post-glacial sea levels, climates and fossil beaches and issuing the first of the regional handbooks for meetings of the British Association for the Advancement of Science as far back as 1874.[2] The club has four sections, Archeology & History, Botany, Geology and Zoology, and has published several books and a periodical. The Herbarium of the BNFC is now in the Ulster Museum.[3]
