Founded in 1929 by Claude Morley (1874–1951), the Suffolk Naturalists’ Society pioneered the study and recording of the County’s flora, fauna and geology, to promote a wider interest in natural history.

Recording the natural history of Suffolk is still one of the Society’s primary objects, and members’ observations are fed to a network of specialist recorders for possible publication, and deposited in the Suffolk Biodiversity Information Service.

Suffolk Natural History, a review of the County’s wildlife, and Suffolk Birds, the County bird report, are two high quality annual publications issued free to members. The Society also publishes a quarterly newsletter and holds two Members’ evenings a year in Spring and Autumn.

The Suffolk Naturalists’ Society offers a joint membership with the Suffolk Bird Group at a reduced subscription. This entitles joint members to receive literature and attend the meetings of both organisations.

If you are not yet a member of the Society but would like to join visit www.sns.org.uk
