In old decalcified coastal dunes these formations occur spontaneously. In 1936 only a very small area of heathland remained. In pine plantations the pedunculate oak has survived in sufficient amounts as single trees; in contrast, the Pyrenean oak only exists in scattered form. Map 10 presents another, more detailed, comparison in the adjacent area of the basin of Rennes and Loire Atlantique, where the original West Armorican oak forests (F4) have been replaced by a variety of other land use types, namely heterogenous agriculture, arable lands, pastures and interspersed wetlands. The main landscape types in this former oak forest region are lowland alluvial landscapes and colline (hilly) areas on crystalline rocks and magmatites with relatively large diversity of agricultural land use. Other selected examples demonstrate similar patterns: while also the larger Rhone delta and the western region of Poland show high land use diversity in comparison to the original vegetation cover, 102
the boundaries of current land use still capture much of the extend and location of the previous natural vegetation units, especially where these are determined by geo-morphological characteristics and/or water bodies. 4.4. Extended version of the European Landscape Map: LANMAP 2 LANMAP 1 had been considered as a prototype for initial testing and method development. Therefore an extended version covering pan-Europe has been realised in 2004 and is still further developed. The resulting European Landscape Map is presented in Map 11. In order to manage the extended data base, the three input data layers had to be further aggregated. However, initial comparisons between LANMAP 1 and LANMAP 2 showed that the changes with regard to the original landscape unit borders (LANMAP 1) can be considered as being within a tolerable range. The new approach includes reference to Alterrra’s Environmental Map of Europe that is largely based on climate assessment (see MÜCHER et al. 2003). LANMAP 2 (landscapemap_v12.shp) is an Arcview shape file with 14.000 landscape mapping polygons. Each of the 376 landscape types has a unique code and the landscape type itself is the LCC code. The LCC code is based on the climate zone, the dominant altitude class, parent material class and land cover class (see Figure 4). LANMAP 2 is currently being revised as part of the EU project “European Landscape Character Assessment Initiative”(ELCAI, WASCHER 2003). 5 Conclusions and Recommendations 5.1 General conclusions With regard to landscapes, we can conclude that natural vegetation provides not only insights on climax plant communities (in Europe mainly forest communities) as a measurement of naturally open versus naturally closed landscapes types, but also on a whole series of other natural parameters that are relevant at the landscape level, namely: � Geology, soils ; � Morphology and exposition; � Hydrology; � Climate; and � Phytogeography and Biodiversity. Since the development of plant communities is a direct function of the bio-physical processes that occur in and between soil, water and air – natural vegetation types can be considered as an aggregate indicator of the main environmental media and systems. Beyond the indicative qualities – especially in hemerobie assessments – the section on biogeographic concepts has also demonstrated that natural vegetation is a key component in the identification of large and coherent holistic life-forms or biomes. The biogeographic dimension of Europe’s natural vegetation as manifested in the map-project coordinated by the Bundesamt für Naturschutz has already played a substantial role in identifying European Ecological Regions. With regard to the actual situation on the ground, namely today’s land cover, any brief interpretation of natural vegetation data will prove the obvious, namely that human land use history has had such a profound impact on Europe’s surface that there is for many parts of Europe hardly any resemblance to be found when comparing natural with real vegetation.

5.1 General conclusions<br />
With regard to landscapes, we can conclude that natural vegetation provides not only insights on<br />
climax plant communities (in Europe mainly forest communities) as a measurement of naturally open<br />
versus naturally closed landscapes types, but also on a whole series of other natural parameters that are<br />
relevant at the landscape level, namely:<br />
� Geology, soils ;<br />
� Morphology and exposition;<br />
� Hydrology;<br />
� Climate; and<br />

Since the development of plant communities is a direct function of the bio-physical processes that<br />
occur in and between soil, water and air – natural vegetation types can be considered as an aggregate<br />
indicator of the main environmental media and systems.<br />
Beyond the indicative qualities – especially in hemerobie assessments – the section on biogeographic<br />
concepts has also demonstrated that natural vegetation is a key component in the identification of large<br />
and coherent holistic life-forms or biomes. The biogeographic dimension of Europe’s natural<br />
vegetation as manifested in the map-project coordinated by the B<strong>und</strong>esamt für Naturschutz has already<br />
played a substantial role in identifying European Ecological Regions.<br />

profo<strong>und</strong> impact on Europe’s surface that there is for many parts of Europe hardly any resemblance to<br />
