Abstract

For achievement to sustainable development and conservation of natural ecosystems and their biodiversity, study on ecological factors and their effects is necessary. Regarding to topographical condition of northern forests of Iran, altitudinal gradient is an important ecological factor controlling many other dependant variables. In order to, 66 sample plots with 400 m2 were selected in GOLBAND forests of Nowshahr. Sample plots were taken from 100-2200m ALTITUDEs in north aspect with 20 - 40 % slope. Tree species with diameter more than 7.5 cm (dbh) as well as herbal species and regeneration density (in five micro plots per plot) were recorded. Homogenous and heterogeneous in general which indices you used for analyses in your work were calculated. Analysis of variance carried out for all of studied indices. DIVERSITY and RICHNESS indices showed significant difference. In relation regeneration (more than 1.30m), Sheldon EVENNESS index showed significant difference. Regeneration biodiversity showed that DIVERSITY and RICHNESS indices had significantly differences as the maximum and minimum were detected in 500m and 2200m ALTITUDE, respectively. ANOVA for biodiversity indices in relation to herbal layer showed that Menhennic RICHNESS index showed significant difference. Furthermore, Simpson and Shannon DIVERSITY indices and Margalef RICHNESS index also showed Sheldon EVENNESS index had not significant differences.
