Les sols urbains, des milieux contraignants pour le développement de l'arbre dans la ville

Abstract : It is no more useful to prove that nature is a crucial need for cities given that is essential for human well-being and the local ecology in cities. However, the phenomenon of artificialization is increasing up to 100% in the towncenters of the major ones. This nature is mainly represented by trees, strong symbolic element, companion of all civilizations. However, in spite of the efforts to insert nature into the city in the last past decades, the life expectancy of a tree in urbanized area rarely exceeds 50 years. In natural environnements, some trees can live more than a thousand years. We are trying within this study, to understand the functioning of the tree and more particularly, its root system. We expose the biological requirements of the tree to the constraints of the urban environment to establish a viable compromise between the alive and the inert. The aim is to sustain the presence of trees in town. This is done keeping in mind that the trees we plant today will be natural heritage of tomorrow, which our children will be able to enjoy. The possible solutions firstly focus on the quality and quantity of available soil to the plant in cities. In reality the knowledge we have on urban soils are poor. The choice of species as well as cultural operations in nurseries is inescapably a key factor in the success of a plantation, due to the heavy influence on the future of the post-planting tree.
