M. virolinensis remains in a single location in Colombia (EOO of less than 100 km2) where it is restricted to forests on the slopes and summits with lower level forests having already been converted to agriculture. It was previously assessed as Vulnerable in 1998 when it was recorded from localities in Boyaca and Santander.

Use and Trade: There have been no reported uses of this species however it is possible that it is exploited for its wood.

Threats [top]

Major Threat(s): Magnolia virolinensis can be found in small fragments of forest generally on mountain summits, isolated by fields with pastures, crops and access to farms, which could result in a continuing decrease of the population.

Conservation Actions [top]

Conservation Actions: Magnolia virolinensis is not found in any reserves however, due to its proximity, it could be located in the Flora and Fauna Sanctuary Guanenta-Alto Fonce Iguaque and its presence here should be determined. It is recommended to evaluate all existing populations and their structures and determine the conservation status. The Virolin region should be considered as a potential reserve as it justifies the high endemism of various plant species in the Magnolicaeae family. There is a need to develop protocols for the propagation of this species.
