It's a commonly held trust climax plants of closed wooded area platforms lined the lowlands of crucial and Western Europe ahead of people intervened in prehistoric occasions to advance agriculture. If this intervention had now not taken position, it can nonetheless be there and so if left, the grassland crops and fields we see this day could revert to its ordinary closed woodland country, even if with a discounted variety of wild species. This booklet demanding situations this view, utilizing examples from historical past, pollen analyses and reports at the ecology of tree and shrub species resembling oak and hazel. It assessments the hypotheses that the climax crops is a closed cover woodland opposed to the choice one during which species composition and succession of crops have been ruled by way of herbivores and that the principal and Western ecu lowlands have been coated by means of a park-like panorama such as grasslands, scrub, solitary bushes and groves bordered by means of a mantle and fringe plants. Comparative details from North the United States can be incorporated, as the forests there are mostly considered as being analogous to the primeval plants in Europe. This identify is a revised, up-to-date and increased translation of e-book released in Dutch.

8, 66; 1935; Moss, 1913, p. 91). According to Moss et al. (1910), and Tansley (1911, p. 71), British forests were descended in a direct line from the original forests. They called these forests semi-natural forests. 5 The forests that Moss et al. e. coppice with a few trees that were left standing. These were usually pedunculate or sessile oaks (Quercus robur and Q. , 1910; Peterken, 1981, p. 108). 4 Tansley’s Polyclimax Theory Tansley (1935) defended himself against Clements’s criticisms of the concept of retrogressive succession by stating that livestock are continuously present, and therefore a continuously active factor, and that forest can therefore change into grassland, slowly but surely.

In addition, it deals with the theories on succession and climax vegetations and the premises on which these are based. Chapter 3 describes how Europe was covered by a closed forest in its natural state, a conclusion based on pollen studies. It deals with the premises which are used in pollen analysis and describes Iversen’s ‘Landnam’ theory. I also examine whether a pollen collection believed to come from a closed forest could also come from a more open type of vegetation such as a wood-pasture.

Chapter 2 describes the development of the theory on succession. It contains an explanation of the development of the climax concept and a description of the models for the regeneration of the climax forest, such as Watt’s gap phase model (1947) and Leibundgut’s cyclical model (1959; 1978). In addition, it deals with the theories on succession and climax vegetations and the premises on which these are based. Chapter 3 describes how Europe was covered by a closed forest in its natural state, a conclusion based on pollen studies.
