Adansonia suarezensis has an extent of occurrence (EOO) of 209 km2 (within the limits for Endangered status under the criterion B2), an area of occupancy (AOO) just 72 km2 (within the limits for Endangered status under the criterion B2) and appears in four locations. Three subpopulations of this species occur outside protected areas and it is threatened by human intrusion, annual fire and forest exploitation. Three subpopulations present in Montagne des Français, Nosy Hara and Oronjia Protected Areas network. Recent study shows that A. suarezensis is vulnerable to climate change and more than half of his population occurs in the future in area that not suitable for the species. This scenario may conduct a loss of population more than 50% until 2080 (Baum 1995). Therefore this species is currently assessed as Endangered.
|Previously published Red List assessments:|
|Range Description:||The species is endemic to Madagascar, where it grows in Montagnes des Français, Beantely forest on W side of the Antsiranana to Cap d'Ambre road and Oronjia Diana region (Antsiaranana province) from sea level to 150 m asl (Baum 1995, Madagascar Catalogue 2016).|

|Population:||There are six known subpopulations of this species. The most recent collection was made in 2007 from Andavakoera, in Antsiranana province (Madagascar Catalogue 2016).|
|Current Population Trend:||Decreasing|
|Habitat and Ecology:||This tree grows in dry forests on limestone, although small trees are also found in disturbed sublittoral scrub (Baum 1995, Madagascar Catalogue 2016).|
|Continuing decline in area, extent and/or quality of habitat:||Yes|
|Use and Trade:||There is no information on the use or trade of this species.|
|Major Threat(s):||The forest's proximity to a rapidly growing mining town leads to intensive wood and charcoal extraction, grazing and hunting. Subpopulations elsewhere are smaller, show few signs of regeneration and are threatened by the rapid depletion of the habitat through human intrusion, charcoal and timber production (Baum 1995, Madagascar Catalogue 2016).|
|Conservation Actions:||This species occurs in Montagne des Français, Nosy Hara and Oronjia Protected Areas. Three of the six subpopulations are protected (Baum 1995, Madagascar Catalogue 2016).|
