As a part of a long tradition, animal farmers of Zavardasht village in Alamut identify their prospective shepherds a few days after the New Year celebration. Shepherds proceed to move the herd towards pasture lands which are rented from neighboring villages. This migratory move towards the highlands follows a pre-planned timetable. For the period of their stay the shepherds use their knowledge of local plants to divide the pasture into grazing zones based on the vegetation of each region. This zone allocation is way to optimize the yield of milk as a result. This paper reports on native knowledge of shepherds about small portion of plants and vegetation of the region.
