Maps 8/9: Map comparison between the European Landscape Typology LANMAP1 (MÜCHER et al.
2003) with the European Natural Vegetation Map (BOHN et al. 2000) – excerpts with high-lighted
vegetation types:
F 1.1/7: Aquitanian pedunculate oak forests (Quercus robur),
F 1.1/8: Atlantic-subatlantic birch-pedunculate oak forests (Quercus robur, Betula pendula, Populus
tremula)
F 1.1/9: Atlantic-subatlantic hygrophilous birch-pedunculate oak forests
F 1.2/15: Euscaldian & south Aquitanian mixed oak forests (Quercus petraea, Q. robur, partly Q.
pyrenaica, Sorbus torminalis)
F 3.1/34: West French and Picard-Belgian mixed pedunculate oak-ash forests
F 3.2/55: Central European sessile oak-hornbeam forests mostly with Fagus sylvatica,
F 3.2/57: Central European sessile oak-hornbeam forests partly with Tilia cordata, few F. sylvatica,
G 3.1/37: Aquitanian mixed downy oak forests (Quercus pubescens, Q. petraea, Q. robur)
J 1.2/14&15: Provencal meso- and supra-Mediterranean holm oak forests (Quercus ilex)
coastal dunes between 1797 and 1865. 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Loire Atlantique, where the original West Armorican oak forests (F4) have been replaced by a variety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,
