Beech forests would cover about 66% of<br />

Germany's land area, with the country<br />

consequently occupying some 25% of the<br />

potential total range of European beech<br />

forests.<br />

Historical and cultural developments have<br />

resulted in the beech forests in the Central<br />

European and German centre of distri b ution<br />

having shrunken by over 90% due to<br />

direct destruction and human interfer ence.<br />

Th e nominated component parts are some<br />

of the very last remains. As regards age<br />

and integrity, these are the prime examples<br />

of the beech forest climax ecosystem at its<br />

centre of distribution.<br />

3.c Comparative analysis<br />

3.c.1 Nemoral deciduous<br />

forests of the world<br />

For the most part, the occurrence of deciduous<br />

forests is limited to the Holarctic of<br />

the Earth’s northern hemisphere. Th ey are<br />

found throughout the nemoral zones for<br />

climatic reasons and are limited to moderate<br />

climates with a minimum vegetative period<br />

of four months, a cold phase in the winter,<br />

and humid-(semihumid) conditions.<br />

Th e genus of beech (Fagus) is a typical element<br />

of deciduous forests. It comprises a total<br />

of 14 species that exist under humid climate<br />

conditions in the three major Holarctic<br />

regions of deciduous forest: in the east of<br />

North America, in Europe / West Asia, and<br />

in East Asia. Its counterpart in the southern<br />

hemisphere is the cognate Nothofagus genus<br />

(Fagaceae) with its approx. 45 species native<br />

to the austral and Antarctic zones as<br />

well as the Australian fl oristic realm, to New<br />

Zealand, and to New Guinea.<br />

Fagus spread all over the northern hemi sphere<br />

during the early Tertiary (PETERS 1997).<br />
