Abstract
Iran is located on the arid belt of the earth, and most of its territory is composed of arid and semi-arid lands. Many of its ecosystems have undergone a retrogressive succession due to human or natural disturbances, which could result in desertification unless vegetation is preserved and restored. Planting is one method to preserve and restore vegetation. This study assessed the quality of tree and shrub species planted as green space in Deh-Imam, Pakdasht county of Iran, from 2014 to 2023. Data were collected using the transect method, and quantitative evaluation was performed using the ranking method. Based on the results, Platycladus orientalis, Ulmus carpinifolia, Pinus eldarica, Melia azedarach and Eucalyptus sp. were significantly healthier than Morus alba, Fraxinus spp. and Robinia pseudoacacia. Further, in nine years, the number of P. eldarica, M. azedarach, Eucalyptus, and Cupressus arizonica increased, while the number of M. alba, Fraxinus sp., Oleae europea, R. pseudoacacia and Ulmus sp. decreased. The base number of P. orientalis remained unchanged. In general, P. orientalis and M. azedarach can be considered the successful and adaptive species of the region's green space.
