                             Foreword
             The General Assembly is the principal policy-forming organ of
             the Union.
             It meets in ordinary session once in three years to carry out
             the functions specified in the Statutes. Since the inaugural
             meeting at Fontainebleau in 1948, the General Assembly has met
             at Brussels, Belgium (1950), Caracas, Venezuela (1952),
             Copenhagen, Denmark (1954), Edinburgh, Scotland (1956), Athens,
             Greece (1958), Warsaw, Poland (1960), Nairobi, Kenya (1963),
             Lucerne, Switzerland (1966), and New Delhi, India (1969).
             The Eleventh General Assembly met in Banff, Alberta, Canada, at
             the Banff Centre at the invitation of the Government of Canada,
             a State Member of the Union, on 11, 15 and 16 September 1972
             in its 41st - 44th Sessions. The present volume contains the
             official documents of the meeting including the report of the
             debates and decisions with the supporting reports and other
             papers.
             An open forum on matters relating to IUCN organization and
             activities was held in the evening of 15 September 1972. A
             series of informal discussion groups on various related topics
             also met during the period of the General Assembly. Reports
             on these matters are given in Section V of the present volume.
             Associated with the meeting of the General Assembly was the
             Twelfth Technical Meeting on the theme: Conservation for
             Development held at the same place on 12 - 15 September 1972.
             The Papers and Proceedings appear separately in the IUCN
             Publications New Series.
             At the time of the General Assembly, two meetings of the Ex-
             ecutive Board and meetings of each of the Commissions took
             place.
             A French version of these Proceedings is also available.
