Ecology, physical and production characteristics of the steppe with Acacia tortilis in the Bouhedma national park (Tunisia southernmost). The present study was conducted in the Bouhedma national park and its surroundings, located in the arid area of Tunisia and considered a Biosphere reserve by UNESCO in 1977 ; it is a protected area with special ecological characteristics and an important dynamics of space occupation. The park contains the only wooded steppe with Acacia tortilis (Forsk.) Hayne subsp raddiana (Savi.) Brenan var. raddiana Brenan in Tunisia. With the aim of safeguarding and management of the park, a better knowledge of the distribution patterns and dynamics of the vegetation of this zone makes it possible to consider program...
