Abstract

Running buffalo clover (RBC) [Trifolium stoloniferum (Muhl. ex Eat.)] is an endangered species whose survival is uncertain. An experiment was conducted on extant RBC sites to investigate biological nitrogen (N₂) fixation, associated plant species, and soil conditions under natural mountain settings. Isotope (¹⁵N) dilution technique was used to calculate quantities of N fixation. Sites were sampled three times within a 2-yr period. Associated plant species were identified, and their dry matter contributions to the total system were assessed.
