  Bio-geographical region:
Bio-geographical regions show the extent of areas with common characteristics, usually based on climatic, topographic and geo-botanical information. Thus the bio-geographical regions show areas with relatively homogeneous ecological conditions. Commonly potential vegetation data is used as a basis for the classificaitons.
The data are used for comparisons and assessments of biodiversity and conservation. Includes both data termed bio-geographical regions and ecological regions. WFD is referring to the use of ecological regions, Natura 2000 to bio-geographical regions. DEMEER: Potential vegetation: Harmonised pan-European data exists.
  Vegetation:
The determination of structure and composition of the natural or near-natural vegetation.
The classification of natural vegetation can be used to interpret ecological/ edaphic/ temperature conditions, environmental pressure and biodiversity modelling.
Used in assessment at European or regiona/ local level, on natural production suitability, ecology, changes.
Scattered data with a variety of classification systems exist at lower levels
  Habitats and biotopes:
Description of living areas for any kind of biota, usually used as a term for describing areas used by zoo-biota. Habitats commonly follow bio-geographical regions/ vegetation types, but habitats can also be described at more detailed levels. Includes small features of the rural landscale - hedgerows, creeks etc.
Linked to Habitats directive. The habitats designated to the directive are mentioned in the "area regulation" data component.
Species distribution:
Species distribution, species by species or grouped to family etc. Often species distribution is being recorded by grid cells. Pan-European mapping initiatives, e.g. for birds, insects, mammals, evertebrats
In biodiversity assessment it is essential to have information on species distribution, quantities, development through time.
Needed for Natura 2000
