Registered Charity No 259211 The Chichester Natural History Society, Chi Nats for short, is a friendly group of local people with a shared interest in all aspects of wildlife, who have been studying and recording all branches of natural history for over 50 years. We do this in an entertaining manner and, in cooperation with other like-minded groups, help conserve the flora and fauna of Sussex. Members of the Society share a common interest in natural history and while some are experts in particular wildlife fields, others are newcomers to the subject. New members are always welcome - Single membership £12 per annum, Joint/Family Membership £22 per annum.
