The population of Bulbophyllum alinae is currently thought to decrease because the habitat of the species has faced and is currently facing selective logging and shifting agriculture. The species also occurs within a mining area. The number of individuals of the species is not known and cannot be estimated since the species is epiphyte.

Mesures de conservation recommandéesExpert
Of the six locations known for Bulbophyllum alinae, only one (represented by two subpopulations) is in a protected area, the Campo Ma'an National Park. However, if the park is placed under protection, the sites where the species was collected inside the park are easily accessible by rpeople living along the river, a situation that threatens the survival of the species.
