Dendroecology of Montpellier maple’s population (Acer monspessulanum) from the North Africa region: Analysis of maple stations characteristics and natural habitat

AbstractAcer monspessulanum (maple) is an endemic endangered tree with a wide but fragmented distribution in the Mediterranean mountains. The persistence of its small populations depends often on few adults, which makes it is highly vulnerable to limiting recruitment factors. In this paper, we examined the regeneration status of this maple in three populations through its geographical distribution in the mountain range of the Tunisian dorsal (Jbel Srerej national park and sacred site). Morphological parameters, genetic variability, and diversity were analyzed as species viability indicators. The ecological site of maple was studied based on the soil texture and structure under the population, additionally to the role of shrubs as nurse plants in maple regeneration dynamic. Here, the maple population in Tunisia was investigated for the first time. The results show that Acer monspessulanum population has a variation terms of height, stem diameter and crown diameter, it also shows that there is a good natura...
