The Study of Flora, Life Form and Chorology of Herbaceous Plants in Protected and Unprotected Area in Shaft, Guilan

This study was carried out to investigate the flora, life form and chorology of herbaceous plants in the protected and unprotected (7 years) areas in SHAFT, Guilan province. For this purpose 30 -1000 m2 circular sampling plots were selected by random- systematic method. Then, tree and shrub species were recorded and sampling of herbaceous species was done. In total, 57 species belong to 35 families and 55 species of 33 families were identified in protected and unprotected areas, respectively. In protected area, Rosaceae had the highest number of species, while, in unprotected areas the highest number belonged to Asteraceae. The study of chorology indicated that the species of euro- Siberian region were dominant in protected and unprotected areas by 12 and 14 species, respectively. hemicryptophytes was dominant life in protected (50.87%) and unprotected area (49%), whereas, Chamaephytes and Geophytes had the lowest number of species in these areas. Systematic planning and optimal utilization of plant cover for livestock grazing needs grazing management which can lead to continuous evaluation of vegetation cover based upon further studies on reconstruction in these ecosystems.
