International Dendrology Society

The International Dendrology Society (IDS) is an international society with members from all over the world and a programme of events, tours and study days. It was formed in 1952 after Mr Robert and Mr Georges de Belder (Belgium) discussed the idea with three other eminent horticulturists, Dr & Mrs Gerd Krüssmann (Germany) and Mr Jacques Lombarts (Netherlands). The aims are to promote the study and enjoyment of trees and other woody plants, to bring together dendrologists from all round the world, and to protect and conserve rare and endangered plant species worldwide. The Society gives grants and bursaries to support these aims. It is a Charitable Incorporated Organisation registered in England and Wales number 1178252, with its office at Hergest Estate Office, Kington, Herefordshire, HR5 3EG, United Kingdom.

The idea of a Society to bring together dendrologists from all over the world arose from a discussion in Belgium in May 1952 between Mr Robert and Mr George de Belder, Dr and Mrs Gerd Krussman and Mr Jacques Lombarts. This was followed up by a meeting on 18 September 1952 at Kalmthout in Belgium when 14 eminent botanists and gardeners, some professional, some amateur, agreed to form the International Dendrology Union (as it was called until 1965). The aims of the Society were, and still are, "to promote the study of woody plants and shrubs and to conserve and protect those that are rare and endangered. Candidates for election do not need to possess professional or scientific qualifications but must have a serious interest in woody plants and in particular trees and shrubs". Members were to be "any person engaged in effective dendrology work and having the opportunity to experience dendrology". Originally it was envisaged that there would only be about 50 members, but the Society has grown over the past 60 years and now numbers about 1,600 members from more than 50 countries. The Tours, originally just visiting other member's gardens in Northern Europe, were the principal activity in the early years and a Tours Committee was established to run the tours programme and encourage members to lead a tour in their own part of the world. The tours programme remains a very important part of the Society's activities and now runs up to nine tours each year all over the world, some leisurely and comfortable, others to wild areas (such as Tibet and Kyrgyzstan) which can be quite hard and distinctly uncomfortable! But the aim for all tours remains "to give us all fun but not to be too scientific." In the mid 1960s, a Conservation Committee was established.
