La Roumanie compte aujourd'hui près de 400 000 hectares de forêts vierges et quasi vierges réparties principalement sur la chaîne des Carpates. Bien plus qu'une fierté, ces forêts constituent pour les forestiers et chercheurs roumains un patrimoine mondial qu'ils souhaitent conserver et faire connaître. L'édition du présent livre est l'une des étapes de cette quête. L’ouvrage se compose de quatre parties, les deux premières présentent la Roumanie à travers son territoire, son histoire et ses forêts. La troisième partie, plus particulièrement consacrée aux forêts vierges, débute par une intéressante mise au point sur la terminologie avec, entre autres, l’introduction de la notion de forêt quasi vierge. Cette section de l’ouvrage s’attache ensuite à caractériser les forêts vierges de Roumanie (histoire, biodiversité, statut…). Des pistes de politique à long terme sont également exposées. Enfin, la quatrième partie de l’ouvrage décrit quelques forêts vierges parmi les plus représentatives du territoire roumain.

This publication deals with the composition and structure of both natural and artificially established tropical forests. After a general introduction, the role of tropical forests in the production of timber is discussed. Attention is then given to the structure of natural tropical forests, especially in Congo, Gabon, Ghana and Laos. The structure of artificially established forests is dealt with in another chapter. At the end, information is given on the thinning of such forest stands in Tanzania.

Natural Woodland describes how woodlands grow, die and regenerate in the absence of human influence, and the structures and range of habitats found in natural woods. The underlying theme is that natural woodlands should form a basis for forest management, policies and practices. George Peterken compares the ecology of both North American and European forests, to produce a fascinating account of woodland natural history for all those concerned with woodland management and ecology.
