Abstract

Frequent occurrence of PATCHes with dominant shrub species is a common characteristic for arid and semi-arid ecosystems. In this study, the effect of shrubby PATCHes on SOIL SEED BANK characteristics was studied in mountainous rangelands in VAZ WATERSHED, Mazanderan province. Soil samples were taken in spring 2011 and spread out under natural conditions in greenhouse to germinate the seeds. Germinated seeds were identified and SEED DENSITY was calculated per square meter. Sorensen similarity between SOIL SEED BANK and above ground vegetation, seed richness, and diversity were estimated and compared between PATCHes and inter-PATCHes. The results showed that SEED DENSITY in PATCHes was significantly higher than that of inter-PATCHes. In addition, Shanon diversity index and richness were significantly higher in PATCHes than those of inter-PATCHes (1.81 vs. 1.37 and 11.86 vs. 7.9 per plot, respectively). Similarity between above ground vegetation and SOIL SEED BANK was significantly higher in inter-PATCHes than that of PATCHes (22.5% vs. 15.5%). The results of this study indicated the importance of small-remained PATCHes with shrub species in seed conservation of grasses.
