As a result of the statistical analysis, there were significant differences in terms of runoff, sediment transport amount and sediment concentration according to season and years, but no significant differences were observed between bare area and caper experimental sites. It has been determined that the adaptation of the caper in the eroded soil and its development is not at the desired level. It is thought that severe summer drought during the growing season negatively affects the survival and development of the caper saplings in the first years of planting. The survival rate of the caper and its low development could not prevent the erosive effect of the rain. It can be said that severe summer drought and soil characteristics (e.g: soil texture, soil water level) have significant effects on growing and survival rates of caper saplings. It can be more useful to use combination with additional erosion control techniques (e.g., soil protection techniques) to make erosion control in this kind of sites where there is irregular and inadequate rainfall. In this study, the growth performance and soil protection ability of the Caper (Capparis sp) in eroded site in semi-arid region of Artvin, Turkey were investigated. For this purpose, the experimental design at the site included a randomized complete block with four replicates (a total of 8 experimental plots: 2 treatments × 4 replicates). Each plot was 20-m long×5-mwide, which is wide enough to minimize edge effects and large enough for downslope rills to develop. Between 2006-2008, water and sediment accumulated in sediment deposited tanks were measured. Then, with the help of these values, the runoff, the amount of transported sediment and the concentration of transported sediment were calculated. In addition, the development of the caper seedlings has been observed and recorded. As a result of the research, the average survival percent of caper sapling in 2006 was found to be 21%. While, the mean height of caper seedlings varied between 4.6 cm and 6.1 cm in 2006, it has been varied between 5.2 cm and 8.18 cm in 2007.
