SPATIAL AND DIAMETRIC EVOLUTION OF A RARE SPECIES, PRUNUS AVIUM, IN DIFFERENT BIOTOPES IN NORTHWEST TUNISIA

This paper aimed to investigate and analyse the diametric and spatial distribution of Prunus avium populations in Tunisia. This study may help us document better information about the ecological processes and its functioning. Dendrometric and ecological data were collected on four square plots of an area of 1 ha each within two forests, Tabarka and Ain Draham, in northwest Tunisia. The results presented in this work show that P. avium individuals present a diametrical structure in the form of an "inverted J" translated by the dominance of the seedlings compared to the other classes. The analysis of the spatial distribution shows that wild cherry is identified by its aggregates and variable size (approximately 5 m and 20 m). It is coherent with the mode of vegetative propagation by suckering and the dispersal of fruits by birds. This investigation opens insight into other species to ensure good sustainable management of natural resources.
