The IBP, as a worldwide programme seeking to expand and co-ordinate
biological research, needed to provide for the protection of sites and
species for future scientific study. The IBP 'check-sheet' survey was
therefore devised as a tool for gathering information, allowing areas to
be evaluated on a comparative basis. In this was it was possible to
examine the extent to which scientifically adequate samples of the main
types of natural biological systems were already protected, for example
in national parks and nature reserves. The method chosen used a
questionnaire approach but on an enormous scale, creating an extremely
valuable report on the procedure of biological surveying, the successes
and shortcomings of which are examined critically. This 1980 volume
explains the procedures adopted in the check-list survey and the
problems of securing adequate descriptions of types of vegetation and
soil and suitable methods of information storage and retrieval.
