In situ conservation of genetic resources of forest trees in metropolitan France

Abstract

The conservation of forest genetic resources aims at the satisfaction of future needs and the preservation of the adaptability of species in a changing environment. The national policy followed by France in this field since 1991 has enabled the creation of in situ conservation networks for beech (Fagus sylvatica), fir (Abies alba) and sessile oak (Quercus petraea) and ex situ collections for a few other species. Diverse research topics and a broadening of the networks organisation are suggested to improve sampling methods, genetic pollution control, and the management of conservation stands. Such a research effort and a better coordination with the habitat protection networks are needed to improve existing and future networks.
