چکیده مقاله:

The effects of 15 years old Italian cypress afforestation on woody plant biodiversitywere studied in North Iran. Three 15 years old Italian cypress afforestation areas andan area of natural broad-leaved deciduous forest stand as studied areas were selectedin the downstream forests of Mazandaran Province. Three plots (20×20 m) werechosen in each studied area and the type of all wooden species were recorded andtheir abundance were counted. Species diversity was calculated by using Shannon-Wiener diversity index. The evenness and richness indexes were calculated by usingSimpson and Manhinc indexes, respectively. Sixteen wooden tree and shrub specieswere appeared in Italian cypress understory naturally, of which, some species wererare. There was no significant difference between the rate of diversity and richnessindex of Italian cypress afforestation and natural broad-leaved deciduous foreststand. From point of view of the rate of evenness, only in one area, a significantdifference was observed between Italian cypress afforestation areas and naturalforest stand. Regarding to the results of this study, Italian cypress afforestation didnot reduce the woody plant biodiversity until the age of fifteen.
