Abstract

Access to basic and up-to-date information on rangeland ecosystems; needs continuous and long-term vegetation measurement. For this purpose, during the years 2018-2021 at a specific time, from the vegetation of plant types representing the saline habitats of Lake Urmia, including; Salicornia europaea, Halocnemum strobilaceum, Aeluropus littoralis- Aeluropus lagopoides- Salicornia europaea, Aeluropus littoralis- Aeluropus lagopoides and Atriplex verrucifera were recorded in the customary system of Osalo. In each of the plant types, considering the dimensions and space between the plant spots, four 300-meter transects with the same azimuth were used, along the salinity gradient, at a distance of 25-50 meters from each other. On each transect, 10 plots were placed at a distance of 30 meters from each other. The plotting was done in such a way that while the distances of the plots were the same, the principle of randomness was observed. Therefore, the starting points of different transects were not the same. Size of sampling units and their dimensions; due to the different distribution of vegetation, the plant types were not considered the same. Plot size for plant types Salicornia europaea, Halocnemum strobilaceum, Aeluropus littoralis- Aeluropus lagopoides- Salicornia europaea, Aeluropus littoralis- Aeluropus lagopoides and Atriplex verrucifera, respectively; 0.5, 2, 0.5, 0.25 and 2 square meters were considered. Average forage production of the study site during 1397, 1398, 1399 and 1400, respectively; 404.6, 456.6, 478.6 and 338.2 kg/ha and the average percentage of canopy cover were 48.4, 54.6, 58.8 and 41.1%. During this period,
