Abstract

Vegetation and soil dynamic study on grazed and ungrazed rangelands is significant for improvement range management. For this reason, the effect of 26 years of grazing protection were studied on vegetation and SOIL INFILTRATION dynamic on two range condition sites (enclosure and EXCLOSURE) in Isfahan, province. Random sampling was done in two range sites using 50 (2x 1m2) quadrates along five 100mlong transect and the vegetation parameter and SOIL INFILTRATION was studied simultaneously in both excluded and exposed range sites. In this study vegetation characteristics as well as vegetation floristic, canopy cover, plant DENSITY, plant composition, plant diversity and SOIL INFILTRATION were recorded during grazing season from 2006 to 2007. The results indicated that vegetation characteristics had significant differences between excluded and exposed range sites (P<0.05). The analysis showed that canopy percentage and DENSITY in the ENCLOSURE and exposed sites had significant difference and their amount increased significantly in ENCLOSURE range site (P<0.01). The VEGETATION COVER in encluded site was mainly comprised of I and II class plants while III class plant mainly occupied the exposed site. Whereas the diversity of the two areas had no significant difference (P<0.45). This research indicated significant increase in gramineae in the ENCLOSURE site compared to surrounding exposed site, but forbs species had considerable decrease (P<0.5). Also this research showed significant decrease in SOIL INFILTRATION in the exposed (Grazed) range site compared to ENCLOSURE range site (P<0.05). Litter was higher inside and bare soil outside the ENCLOSURE (P<0.05).The results of the experiment showed that infiltration rate reduced from ENCLOSURE area to EXCLOSURE area as well as through grazing season. Comparing vegetation and SOIL INFILTRATION on ENCLOSURE show that vegetation condition and SOIL INFILTRATION were good, and ENCLOSURE cause improve range condition in this region.
