Bamboo is widely recognized as a highly renewable, fast-growing, economic raw material. Moreover, bamboo has the capability of mitigating climate change as it restores degraded land , act as carbon sequesters and protects from soil erosion. The study evaluated the effects of provenance variation on growth performance of indigenous highland bamboo species (Arundinaria alpina) in Bore District, Southern Ethiopia. Three provenances of indigenous highland bamboo species (Arundinaria alpina) such as Dimtu Hambela, Injibara and Shanan were collected from different parts of the country. Those collected provenances were planted in Bore Agricultural Research Center, on station in a Randomized Complete Block Design in three replications. Dimtu Hambela provenance had higher survival rate (85.1%) followed by Shanan (65.6%) and Injibara (64.8%) provenances. The maximum number of new emerged shoots (21.3) and number of nodes (29.9) were recorded in Dimtu Hambela provenance. In terms of root collar diameter and diameter at breast height, Dimtu Hambela provenance had (3.01cm) and (3.56cm) respectively. However, root collar diameter (2.23cm) and (2.12cm) and diameter at breast height (1.72cm) and (2.36cm) were recorded from Injibara and Shanan provenances respectively. Moreover, the highest internode length (32cm) and culm height growth (5.7cm) was recorded from Dimtu Hambela provenance followed by Shanan and Injibara provenances. Therefore, based on their growth performances Dimtu Hambela and Shanan provenances of indigenous highland bamboo species (Arundinaria alpina) were recommended and they could be demonstrated and popularized around Bore district and in similar climatic condition. Furthermore, vegetative propagation study of the recommended provenances should be mandatory in order to expand the indigenous highland bamboo resources.
