The article presents some historical evidence about the veneration of individual trees, primarily the juniper and the oak-trees, traditionally considered to be sacred in the Zaza culture, as well as generally groves and forests. Unfortunately, the once vast and rich forestal covering of the Zazas’ main habitat in Dersim (Tunceli), which was a proverbial phenomenon still in the beginning of the 20th century, has been almost totally exterminated as a result of the mistreatment by the Turkish government. The folk beliefs related to tree worship have also been considerably erased from the people’s memory, lingering on only among the elderly in the remote mountain villages as a dwindling echo of the past.
