The purpose of research on the regeneration characteristics of Black Bamboo to find out propagation methods. Conducted research using the following methods Professional solution participatory rural assessment method PRA and KEYWORDS field investigation to determine the regeneration characteristics of black bamboo Black bamboo Phyllostachys distributed in the wild. The results of the study on natural regeneration nigra characteristics of Black bamboo in two provinces show that Black bamboo has the ability to regenerate well by the form of underground stem and underground body Ha Giang whip . The trunk whip grows from the trunk of the tree trunk with 3-5 sleeping Lao Cai eyes the most birth is 5 underground body.
