Abstract
The fabaceous shrub Caragana korshinskii Kom. is native to northern China and is commonly used for dune revegetation. However, the sustainability of revegetation by C. korshinskii depends on natural regeneration through seeds. We surveyed seed dispersal and seedling dynamics of C. korshinskii on a revegetated dune in Inner Mongolia, China and evaluated the possibility of natural regeneration. Seedling emergence and death were affected by changes in soil moisture caused by rainfall. The number of seedling that emerged during the study period corresponded to 6 % of the seeds dispersed, and about half of the seedlings survived till autumn. Natural regeneration was possible in C. korshinskii on a revegetated dune in Inner Mongolia, but it may be affected by the rainfall pattern during the summer. As livestock was excluded in this study, grazing effects should be considered in the future research.
