World Geographical Scheme for Recording Plant Distributions
The World Geographical Scheme for Recording Plant Distributions is a biogeography system developed by the international Biodiversity Information Standards—TDWG, formerly The International Working Group on Taxonomic Databases. Developing these standards for data fields in botanical databases was done to promote the wider and more effective dissemination of information about the World's heritage of biological organisms for the benefit of the world at large.
Plant Distribution scales
- Continental — botanical continents
- Regional or sub-continental;
- "Botanical Country" — generally equates to a political country, but may split large countries or omit outlying areas.
- "Basic Recording Units" — only used for very large countries, to subdivide into states or provinces on purely political grounds.
The World Geographical Scheme for Recording Plant Distributions defines nine botanical continents:
- Northern America,
- Southern America,
Principles of organization
The scheme is particularly aimed at taxonomic databases. It represents a compromise between political and botanical divisions. All boundaries either follow a political boundary (country boundary, province boundary, etc.), or coast lines. The scheme aims to follow botanical tradition, in terms of the categories of works like the Flora Europaea, Flora Malesiana, or Med-Checklist.
