Yew in Arasbaran forests is mixed with broad-leaved species like hornbeam, oak and maple that has been destroyed very much in the past years. This study is aimed to investigate the natural regeneration of yew in these forests. For this purpose, 111 sample plots, each 100m2, were established by a systematic-random grid of 100m×250m. The natural regeneration (saplings) of yew was investigated quantitatively and qualitatively in the sample plots. Results showed that the number of yew saplings per hectare were 520. Most of these saplings had seed origin and were classified in height class less than 30cm with high vitality and health condition. Regarding to the past history of the area, this results show that the protection of area was effective and successful, so a dense and fresh yew stand in the Arasbaran area is expected in the future, if the protection is continued.
