Abstract: 

This study aims to determine zone effect of secondary forest roads on flora, life form and chorology of beech-hornbeam stand in Kheyroud forest of Nowshahr.36 transects with the length of 100 m (number of 18 transects on each of up and down slope) from road edge in to the forest interior were selected, also number of eight plots with the size of 1´2 m at the distances of zero (road edge), five, 10, 15, 20, 30, 45 and 100 m were established. Edge effect of roads on the frequency of the plants was appeared up to five meter because after this interval, Fagaceae and Betulacese families were dominant and Rosaceae, Cyperiaceae, Aceraceae and Poaceae were as a light tolerant family so the presence of them decreased.
Edge effect of roads were apparent up to five meter, because after this distance Chamaephytes did not exist and life form of the study site changed from Phanerophytes to Hemicryptophytes. Roads of the study site had an effect on chorology up to five meter. After this distance semi cosmopolitan and cosmopolitan decreased and percentage of Pluriregional and Europe-Siberian increased.
