This thesis is a literature study. It focuses on the theory that a climax vegetation of closed forest systems covered the lowlands of Central and Western Europe in prehistoric times before man intervened and that it would still be there had this intervention not taken place. The theory also states that man's intervention, notably the introduction of livestock, has led to the disappearence of this climax vegetation in a process known as retrogressive succession. By the grazing of livestock the forest was degraded to thorny scrub and ultimately to grassland. According to the theory, it will revert to its natural vegetation of closed forest systems once the grazing of livestock is stopped.The problem central to this study is that literature shows that pedunculate oak ( Quercus robur ) , sessile oak ( Q. petraea ) and hazel ( Coryllus avellana ) do not regenerate and cannot survive in closed forest systems while pollen analyses show that these species were present continuously in Central and Western Europe for 10,000 years since the end of the ice age. On the other hand these species do regenerate in park-like landscapes in the presence of grazing by cattle and horses, domesticated descendants of wild progenitors, and deer in so called wood-pastures.The null hypothesis formulated in this thesis is that pedunculate oak, sessile oak and hazel have survived in the closed forest systems in the lowlands of Central and Western Europe and that the grazing of the indigenous large herbivores, such as aurochs ( Bos primigenius ), tarpan or European wild horse ( Equus przewalski gmelini ), European bison ( Bison bonasus ), Elk ( Alces alces ), red deer ( Cervus elaphus ), and roe deer ( Capreolus capreolus ), that inhabited these regions did not affect the composition of species or the succession of the forest in prehistoric times. The alternative hypothesis is that, in prehistoric times, the natural vegetation in the lowlands of Central and Western Europe was a park-like landscape, consisting of a mosaic of grasslands, scrub ...
