État de la populationTexte officiel évaluation IUCNExpert
The population of Angraecum sanfordii is currently thought to b declining because the habitat above Buea in Mount Cameroon is currently facing selective logging and clearance for agriculture and urbanization. The species is known from five subpopulations that represent two different locations. The number of individuals of the species is not known and cannot be estimated since the species is epiphyte.

Mesures de conservation recommandéesStratégies de conservation IUCNExpert
Angraecum sanfordii is known from five subpopulations representing two different locations, of which only one appears under protection. In fact, much of the forest above 1,000 m, around the summit of Kupe rock has some form of protected status with a limited disturbance. However, efforts to rediscover the population on the eastern slopes of Mt Cameroon should be made. A survey of its population on Mt Kupe, particularly at lower elevations, would allow a better assessment of its status on the mountain, seemingly the stronghold of this species. The species is cultivated in the Yaoundé shade house.
