The development of the National Vegetation Database (NVD) is due thus far, to the goodwill and cooperation of surveyors who have kindly shared their data with the National Biodiversity Data Centre for inclusion in the database.
The pie chart below shows the main source categories for relevés captured in the NVD. The numbers refer to the number of relevés provided by each source.
The bibliography below provides a list of all sources of vegetation data that have been included in the NVD as of the end of 2014.
If you are aware of significant existing vegetation data sources that have not been included in the NVD please contact us.
