Abstract
Most bamboo has a tight sympodial rhizome root system that can be used for conservation of river border. Generally, bamboo in each watershed has a variation, such as in Tiupupus watershed North Lombok District, there were found 4 bamboo genera, 9 species, and 1 variety while in Meniting watershed, West Lombok District, there were found 6 genera of 8 species of bamboo. This study aims to determine species of bamboo and its distribution along buffer zones of the Kedome river in East Lombok District. Sampling method was conducted by exploring the bamboo in the buffer zone as long as 6.000 m, the width of the two paths on both sides of the river was 50 m each. Data were analyzed using description method. The results showed: there were 3 bamboo genera, 5 species and 1 variety e.g. Gigantochloa apus, Gigantochloa atter, Thyrsostachis siamensis, Bambusa maculata, Bambusa vulgaris, and Bambusa vulgaris var. vittata. Species of Gigantochloa atter and Bambusa vulgaris have tight sympodial rhizome roots, rounded and thick canopy. Both types of bamboo are recommended to be used as soil and water conservation plants in the watershed.
