The International Dendrology Society (IDS) is an international learned society and registered charity devoted to dendrology, the study of trees and other woody plants. It was established in 1952 by the Belgian arboriculturists Robert and Georges de Belder, the German dendrologist Gerd Krüssmann and his wife Edeltraut, and the Dutch nurseryman Jacques Lombarts, and is now headquartered at the Hergest Estate Office in Kington, Herefordshire, adjacent to Hergest Croft Gardens.[page needed][1][2] Its stated aims are to advance the knowledge and study of woody plants worldwide, to bring together dendrologists across professional and amateur backgrounds, and to support the conservation of rare and threatened arboreal taxa; the society operates with approximately 1,600 members in fifty countries and runs an annual programme of study tours, symposia, and bursaries for younger dendrologists, and routinely intervenes with national authorities where arboreta or wild woody-plant populations are reported to be at risk.[1][3] The IDS publishes a peer-reviewed Yearbook and a quarterly Newsletter, and since the early 2010s has hosted its flagship reference work, Trees and Shrubs Online a free open-access online encyclopaedia of cultivated temperate woody plants that incorporates the IDS book New Trees (2009) and the eighth edition of W. J. Bean's Trees and Shrubs Hardy in the British Isles; as of 2026 the site held more than 16,000 species and cultivar articles illustrated by over 30,500 images.[4][1]
