Magnolia georgii is a range restricted species, with an extent of occurrence (EOO) of less than 5,000 km2. It is known from two locations in forests that are fragmented due to pressure from habitat conversion for agriculture and roads. It has a very restricted altitudinal distribution. This species has experienced a continuing decline in area and quality of habitat due to deforestation for agriculture and infrastructure. The number of mature individuals is also likely to be declining as this species is used for timber. Therefore, this species is assessed as Endangered B1ab(iii,v).

Geographic Range [top]

Range Description:Magnolia georgii is endemic to Colombia. It is known from the western slopes of the eastern mountain range, between the north part of the Boyaca department and southern part of the Santander department between altitudes of 2,300 and 2,400 m asl. It has an extent of occurrence (EOO) of less than 5,000 km2 from two known locations.

Habitat and Ecology [top]

Habitat and Ecology:Magnolia georgii is a canopy tree of sub-Andean humid forests. It flowers and fruits in July and October. This species is commonly known as 'Cucharo' as its leaves are spoon shaped and thick and it grows exclusively in the eastern mountain range. Two trees were found in Santander Province with flowers and fruits but not seedlings or saplings (Serna pers. comm. 2015).

Continuing decline in area, extent and/or quality of habitat:Yes

Use and Trade [top]

Use and Trade: Magnolia georgii is used for its wood for roundwood and sawlogs.

Threats [top]

Major Threat(s): Magnolia georgii is only known from two localities where the habitat is fragmented mostly due to land clearance for agriculture, pasture and construction of access roads. It is used for timber.

Conservation Actions [top]

Conservation Actions: It is possible that Magnolia georgii could be present in the Flora and Fauna Sanctuary of Iguaque. It is recommended to further evaluate the status of existing subpopulations, determine its presence in the Flora and Fauna Sanctuary of Iguaque and other surrounding reserved areas. There is a need to develop protocols for the propagation of this species.
