The choice of tree species as a strategical concept

Abstract

The choice of species is not a goal in itself, but a means to an end. It is a natural phenomenon and part of the management of a vulnerable ecosystem. It has to do with the plantation and the forest sensu-stricto and with all possible transitions between these fundamental types. It has a double objective: the stability of the ecosystem and the continuity of its use, needing the acceptance of a dual strategy and a broad conceptual vision on forest use and forest care. The choice of species is not unique and never definitive. It has to be done at several occasions and on different levels of forest development. It must acknowledge the multiple realities of change. The choice must not be made between fast growth and slow growth, between tolerant and intolerant species, but aim at rightful use of species in adequate combinations of time sequences and space patterns. Homogenisation by choosing a single species should be the exception, because of the ecological and functional limitations. The choice of species should be part of a coherent strategy recognising and respecting the natural strategies for colonisation, exploitation, adaptation, differentiation and conservation.
