The survey of regeneration diversity in managed and unmanaged beech stands of north forests of Iran

In this study regeneration diversity from the aspects of evenness and richness were compared and examined in the managed and unmanaged Nave-Asalem forests in north of Iran. In order to perform this survey, two parcels managed and unmanaged ones- were chosen for the reason that they had identical species and physiography. A randomsystematic inventory was done with a 100 m× 100 m inventory network and 7R 700 m sample pieces. For analyzing the data, different indexes of tree species regeneration in each sample piece was computed, and for the examination of considerable difference, the differences among the indexes means were used in two parts of the t-test. The results revealed that among the diversity mean of Shannon-wiener, N Hiill and N Mc-Arthur indexes in managed and unmanaged stands a considerable difference in a 5% level exists. Also among Brillouins's diversity index mean in two stands was a considerable difference in the levels of 1% and 5%. In this case the most increases were observed in N Hiill index with the amount of 1.973 and N Mc-Arthur index with the amount of 2.127 in the managed stand
