Abstract

Diversity of plant species in a community changes in response to topographic factors such as ALTITUDE, aspect and slope. This study examined diversity changes in relation to TOPOGRAPHY in DODANGEH FORESTs, in the south of Sari, Iran. Plant species were collected in sample plots and the cover percent of each species was recorded using quadrat plots of 400 m2 and 237 plant species were characterized in the area. All the quadrats were divided into 7 altitudinal, 3 slope and 8 aspect classes. Discriminant function analysis showed that ALTITUDE is the most effective factor to discriminate plant communities. The data were also subjected to analysis by specific diversity packages to characterize and obtain SPECIES DIVERSITY and evenness indices as well as species abundance models. Results showed that the highest SPECIES DIVERSITY (Shannon's index (H)=1.5-1.6) and evenness (Smith & Wilson’s index (E)=0.38-0.42) were observed in the moderate levels of ALTITUDE. Also it was found that the south, southeast and southwest facing slopes were more diverse than the northwest ones because of more available radiation and temperature. So, vegetation of the area accords with Gleason’s continuum view of communities.
