| Many endemic plants with limited distributions are in danger of extinction and their protection is a priority. Quercus castaneifolia is an endemic species distributed in the Caucasus Mountains and northern Iran. The conservation status of the species was defined based on IUCN Red List criteria and categories. The Extent of Occurrence (EOO) in Iran is 153172 Km2, and the conservation status of this species is defined as LC (Least Concern). Based on EOO, Q. castaneifolia is not a threatened species in Iran. We managed to collect plant samples and habitat information from 36 populations of this species in different habitats of the country. The Area of Occupancy was measured as 1339 km2 and evaluated as vulnerable (VU), but based on the forest measurement reports, the authors' studies, and field observations, Q. castaneifolia has a wide, continuous, and good coverage in the northern regions of the country from sea level to the upper heights of the forest, and is one of the dominant species, making plant communities as mixed stands with other trees, and regenerates well. So, considering all these data, we evaluate it as Least Concern (LC) in Iran. Nevertheless, because the Hyrcanian Forests are fragile and lowland habitats in Iran are threatened and changing rapidly, as well as high exploitation of timber and compaction of the soil at the base of the trees, all create problems for its survival and continuation. There must be regular surveys and monitoring programs on its populations, conservation status, and protection by Natural Resources and Watershed Organization. Furthermore, botanists should do regular periodical surveys on Q. castaneifolia and report its conservation status to the relevant authorities. Expanding its use in parks, arboriculture, botanical gardens, and forest plantations will significantly help to protect this valuable species in the country. | ||
