The range of Rhipsalis russellii is markedly disjunct. Its habitat has severely contracted, especially in southeastern Bahia, where the most recent collection was obtained in 1971. Elsewhere, it is found within some reasonably secure protected areas, such as Parque Nacional Chapada Diamantina in Bahia, but its ecological niches are invariably limited. The area of occupancy is estimated to be less than 2,000 km², the range is severely fragmented, and there is continuing decline in area of occupancy, number of locations and subpopulations, and loss of mature individuals. This cactus therefore qualifies for listing as Vulnerable under criterion B2.
