Abstract
One of the problems in the field of biological restoration of the wetlands of deserts is the lack of diversity of species compatible with existing conditions and how establishment. Natural potential of moist margin of salt lake in Kashan during a research project entitled "Geochemistry and vegetation cover characteristics of Iranian wetland margins for their biological recovery (identification of habitat potential)" were identified and were zoned areas with different salinity and groundwater levels. Using the information of the above design, in order to enrich the species diversity and biological regeneration of the wet margin of salt lake, the establishment of 6 species of Suaeda fruticosa, Halostachys caspica, Atriplex halimus, Salsola imbricata, Halocnemum strobilaceum, Aeluropus littoralis, based on Complete randomized blocks were studied under species in 3 replicates. In this regard, after collecting the seeds of above mentioned species and determining the genus, they cultivate at the arid and desert areas research station of Kashan, and then cultivate according to the plan of the project implementation. The main trait was evaluated for survival percentage, but traits such as height and diameter of the canopy were also measured during the 5 years of the project. The results were analyzed in SPSS environment and it was determined that H.strobilaceum, S.fruticosa, H.caspica, S.imbricata were 5.67, 5.11, 5.56 and 4.9, each with the highest survival has been implementing the plan for the last 5 years. Considering the high nutritional value and favorable palatability for the camel, it is recommended to cultivate in the wet margin of the salt lake for prevent wind erosion and dust.
