The IVC has a hierarchical structure with six levels. The aim of this hierarchy is to organise the defined plant communities in an intuitive fashion and provide options for users in terms of the level of detail used in recording or mapping. The upper three levels are based on physiognomy and ecology, whereas the lower three levels will be based on floristic data.

The navigation tree below begins at the division level and can be used to explore the IVC and find links to individual community descriptions. Currently, the grasslands, woodland and saltmarsh sections of the classification are available. Web-based descriptions are available for all 59 community types. Full pdf descriptions of each community can be downloaded from the respective webpage. As the project progresses groups, communities and sub-communities for other divisions will be added.
