According to today's definition, artificial forests in Iran are half a century old. Most did not have production goals and were done to develop green space and protect the environment. Semnan province is one of the country's most extensive provinces, containing various natural environments. The current research investigated the current situation of plantations in the Irano-Turanian region of Semnan province. This was done by using responsible institutions' and people's information and confirming and supplementing it with field studies. Semnan province in the Irano-Turanian region has 68 plantations and forest parks, with 30 species of trees and shrubs used for planting. Afforestation in Semnan province started in the 1340s and increased from the 50s to the 90s. 32% of plantations are irrigated by tanker and 31% by drop irrigation. The current success rate of afforestation in Semnan province was about 75% on average, and the most critical reason for failure was irregular irrigation. In addition to the lack of water resources, the transfer of park management to the municipality, the lack of financial resources, and the lack of human force to protect the forests were also evaluated as the most critical problems of plantations and forest parks in Semnan province.
