The selection of forest species and the analysis of their behavior variability, considering the main environmental factors, remains a major concern for the forester in Tunisia. This work is prepared to answer the following question: for reforestation needs, which is the most suitable species to reach a sustainable and productive plantation? The answer can be provided in the elimination trials in the arboretum. The arboretums offer an ideal experimental support to know the requirements of the forest species and to make a selection in favor of the best adapted and the most efficient species.
• Establish, by compilation of data obtained from collectors and producers, a list of plant species picked for artisanal or industrial production chains,
• Referencing these species according to their validated scientific name,
• Provide some indicators of the risks that could weigh on these species.
