Determination of allowable use for Stipa hohenackerian in semi-steppe rangelands of Iran
Journal Title: Journal of Biodiversity and Environmental Sciences (JBES) - Year 2013, Vol 3, Issue 6
Abstract
Current research was carried out in selected sites of semi-steppe region including Arshagh (Ardebil), Firoozkooh (Tehran), Kordan (Alborz) and Jashloobar (Semnan). Stipa hohenackerian is a key and palatable species which has a considerable portion in rangeland yield. For this purpose, 40 similar species of Stipa hohenackerian were selected in each site. Selected species were exposed to different harvesting intensities of 25, 50 and 75 and 0% as control group. Data were analyzed by SPSS and MSTATC and Duncan’s Multiple Range Test was used for mean comparisons. According to the results, no significant differences were recorded for 25 and 50% harvesting intensities in terms of studied traits but a harvesting intensity of 75% negatively affected Stipa hohenackerian. Consequently, a harvesting intensity of 25-50% is recommended as the best allowable use for Stipa hohenackeriana in this vegetative region and other similar areas.
