La Société Guernesiaise was founded in 1882 to encourage the study of the history, natural history, geography and geology of the Bailiwick of Guernsey, the conservation of the Bailiwick's natural environment and the preservation of its historic buildings and monuments. La Société:

  • Publishes an Annual Report and Transactions and regular newsletters
  • Holds meetings, lectures, excursions and events
  • Manages nature reserves
  • Carries out research, gathers environmental data and maintains a research library and collections
  • Publishes books and other publications
  • Provides advice on conservation issues.

La Société owns, leases or manages some 30 separate areas of land. These include the four major reed-beds on the island, and some superb orchid fields, which are considered to be some of the best in the British Isles.
