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 |
