Biodiversity Conservation in the context of tropical Forest Management / Francis E. Putz

Public ISBD Titre : Biodiversity Conservation in the context of tropical Forest Management Type de document : texte imprimé Auteurs : Francis E. Putz, Auteur ; Kent H. Redford, Auteur ; John G. Robinson, Auteur Editeur : World Bank Année de publication : 2000 Importance : 80 p. Langues : Anglais (eng) Catégories : SCIENCES AGRICOLES Mots-clés : BIODIVERSITE  GESTION DE LA FORET  CONSERVATION DE LA NATURE Résumé : Protected areas and existing parks are cornerstones of biodiversity conservation but on their own, they are inadequate to assure the continued existence of a vast proportion of tropical forest biodiversity. As a result, priority must be given to ensuring that the greatest possible amount of biodiversity is conserved outside protected areas by altering harvest patterns in these landscapes of resource extraction. Of all forest uses within trpoical forests regions, logging or timber harvesting is the most important to influence because not only is it the most lucrative but also it causes the most severe direct and indirect environmental impacts. The analysis produces a number of key findings. All consumptive uses affect some component or attribute of biodiversity, commonly affecting not only the target resource but other elements as well. As a result only fully protected areas conserve all components and attributes of biodiversity. Recognizing that all significant interventions in natural forests have biodiversity impacts, all silvicultural decisions represent compromises. Management for some goods or services involves management against others. Different intensities and spatial patterns of timber harvesting, along with other silvicultural treatments result in different effects on the different components of biodiversity. Some components and attributes of biodiversity are more sensitive than others to forest management activities. There are some forested areas and some areas within forests which should never be logged. Biodiversity objectives can and should be established within production forests and finally, in many cases the logging itself is not the major cause of biodiversity loss but rather the indirect effects, often promoted by the presence of the roads, id est the major environmental threats.
