Comparative study on height and survival of seven plant species planted in 2017 in hillside ditches under semi-arid conditions at Paya Muslimabad, District Kohat was carried out. Seven drought resistant tree species were planted in three replications on RCB design. After plantation in 2017 the survival and height data of each species were collected every year in June till 2020 and analysed statistically. Acacia ampliceps and Acacia elata gained maximum height than Acacia nilotica, Zizyphus mauritiana, Acacia victoriae, Acacia catechu and Acacia stenophylla

Mean heights recorded for different species were not significantly different from each other. Maximum survival percentage (75%) was recorded for Acacia catechu followed by Zizyphus mauritiana (74%) and the lowest survival percentage (62%) was recorded for each Acacia ampliceps and Acacia victoriae in the final year 2020. The mean values of survival among the different species were not significantly different from each other.
