    The present work aims to identify the biodiversity of fruit tree species in the region of Ouargla (Algeria) and to analyze the distribution of local cultivars and introduced varieties. The method adopted is to carry out surveys in the stations in the region of Ouargla Ksar Ouargla, Rouissat, N'Goussa and Hassi Ben Abdallah. The region of Ouargla seems to be the richest in fruit species with a biodiversity of 12 species. The pomegranate is present with a frequency of 29% in the traditional sector of the stations studied. The average values of the index of Shannon-W, for the study area are very low, they are estimated at 0.88 bits in the traditional sector. The average equitability is equal to 0.77 in the traditional farms. The regularity is high and the numbers of species present tend to be in equilibrium. Local cultivars, from this region, are found for pomegranate and fig. Many species are rare and are found in a few farms. The edapho-climatic conditions of the region and the salinity of the water and soil seem to be the limiting factors for this crop in the region. The preservation of this biodiversity, especially the local cultivars, as well as the implementation of a selection program and possibly of crossbreeding seem to be essential to promote the culture of fruit trees in the region of Ouargla.
