Abstract:
Regeneration and forest durability guarantee is one of the most important aspects of forest sustainability and it should be placed in forest plans priority. To compare regeneration in the two grazed and non-grazed forest, Baghe-shady forest located in Khatam city (it has the preservative regions that they are 20 years old), Yazd province, Central of Iran was selected. For this purpose, 60 sample plots (30 plots in the grazed and 30 plots in the non-grazed area) were sampled by arandomized-systematic method with 100 m2 square plots (10×10 m) in the Net 100×200 meters were sampled. In every sample plot recorded regeneration and health condition. T-test was used to analysis of mean regeneration differences between grazed and non-grazed area. To analysisdata use the SPSS16 software. Results showed the mean of sound seedlings of almond, pistachioand Monpollier maple in the non-grazed region were more than grazed region. These results indicated that non-grazed region more preference than grazed region. Regeneration in non-grazed region was less than grazed region. T-test indicated significant difference between non-grazed and grazed region for sound and height seedlings. Overall results showed that the grazing have a negative effects on regeneration. To manage of this forest authors suggested that continue preservative plans (non-grazed area) and provide foliage for cattle.
