摘要：This study was conducted in an uneven aged deciduous natural forest of Hyrcanian zone to evaluate the status of trees diversity at the edge of streams and forest road. Transects were established parallel to road and perpendicular to stream and then all regenerations and trees were counted in circular plots on each transect. Past software was used to apply Shannon biodiversity index, Margalef richness index and Camargo evenness index. Results show that biodiversity index decreased with increasing distance from road edge and stream. Shannon heterogeneity index at the edge of stream (2.06) was more than that of road edge (2.03). Indeed trees species diversity tended to increase at the edge of forest roads and streams of study area.
