Abstract:
This study was conducted in four sites located in Lattakia governorate during the period between 2021-2022, and it aimed to estimate the current plant biodiversity from the city center towards the suburbs and to determine the integrity of the species richness, and compare the change in the diversity of tree species. The results showed that there were clear differences in the distribution of the total number of plant species among the study sites. it was found that the site located in the suburb of Buka, has a greater species richness, which the Arab Technical Institute for Agriculture and Fisheries recorded 90 species, followed by the Panorama garden and gardens of Ain Um Ibrahim with 58 species and 38 species respectively, while the lowest number was recorded in ALmashroa ALsabea garden with 14 species. The results also showed that there is a relative closeness between the city and the suburb in terms of endemic and exotic species, which the percentage of exotic species in the city reached 69,8% and in the suburb 68,9%, while the endemic species recorded a percentage of 30,2% in the city compared to 31,19% in the suburb. The similarity between the city and the suburb was 50%. Most of the families achieved the required percentages in the plant composition of the studied sites, while the percentage of some species and genera exceeded the permissible percentages in the study areas.
