        1997 IUCN Red List of Threatened Plants

        Data Sources

        A critically important feature of the WCMC Threatened Plants Database is the linkage maintained between many data fields and their data sources. Considerable effort is made to ensure that the source of plant names, distribution and conservation status is tracked, ensuring that credit is given to the primary sources of data and that users can judge the validity of the data provided. A complete list of all the data sources used in the production of this Red List is included following the main list.

        The current practice while entering data into the database is to require the relevant data source number for all new plant names, distribution or threat data. However, prior to 1990, the practice was slightly different, and not all of these fields were mandatory in the earlier database. Although efforts have been made to fill in missing fields during the preparation of this list, time and resources have not permitted all missing data sources to be checked and updated from the original card index system.
