The relevé data of the National Vegetation Database (NVD) is held within vegetation data management software called Turboveg. It was designed to store phytosociological vegetation data and is used by the European Vegetation Survey. The software contains multiple export functions to a range of analytical tools (including JUICE, PC-ORD, R)  and can also be linked to an information management system that includes spatial data (e.g. DMAP).

Species Dictionary:

‘Ireland2008′ is an Irish plant checklist that was specially constructed by the National Botanic Gardens for use within the National Vegetation Database. It includes vascular plants, bryophytes, lichens and charophytes and incorporates all known synonyms that have been used in Ireland. ‘Ireland2008’ was installed as a Turboveg dictionary by Stephen Hennekens and is supplied with the version of the software distributed in Ireland. All data held in the National Vegetation Database is based on this taxonomy. All taxonomic updates to the dictionary ‘Ireland2008’ are controlled by the National Botanic Gardens. Outside this, the checklist is managed as a working dictionary for the National Vegetation Database by the Data Centre. The Irish checklists are available on the National Botanic Gardens website.

Data Quality:

To ensure the quality of the vegetation data in the NVD, only relevés which contain the minimum mandatory information are included in the database.

Datasets can only be included in the NVD if the data have passed a validation process

All surveys in the NVD are accompanied by a data entry log to track any changes made during the data entry process.  

All surveys within the database are accompanied by metadata

Fossitt Habitat categories

All relevés in the NVD have been allocated a Fossitt habitat code.The Fossitt habitat classification scheme, initiated by the Heritage Council is based on categories that are defined primarily on vegetation present but also other factors including geology, hydrology and altitude.

It is hoped that in time, the data will also be classified phytosociologically by the construction of a National Vegetation Classification System
