Justification
This species is considered to be Endangered due to its restricted range. It is only known from three locations in the eastern mountain range between Santander and Boyaca and the east of Cundinamarca, Colombia with an extent of occurrence (EOO) of 2,385 km2. Further surveying is needed to determine whether the species occurs in less accessible areas. The remaining populations are under pressure from habitat conversion and logging.

Major Threats
Historically the fragmented forests of the region have been subject to logging mostly to clear the land for livestock and agriculture.

Management

Conservation Actions

Conservation Actions
It is important to determine whether M. arcabucoana occurs in wildlife corridors between its three known locations which could harbour populations from Arcabuco and Virolin. Further survey is needed of the Farallones de Medina region which has high slopes and very little settlement and could potentially harbour this species.

There are no existing records of Magnolia arcabucoana in protected areas but it is possible that it occurs in the Flora and Fauna Sanctuary Guanenta-Alto Rio Fonce e Iguaque and in the Nature National Park of Chingaza. These areas should be explored to determine the presence of this species.

Based on herbarium records it is a species for which very few specimens have been collected and there have been no new collections since 1981. It is necessary to develop protocols to assist the regeneration of this species. It does not occur in any ex situ collections.
