The Northern Highlands are a mountainous biogeographical region of northern Madagascar. The region includes the Tsaratanana Massif (with the highest mountain of Madagascar, Maromokotro) and smaller nearby massifs such as Marojejy, Anjanaharibe-Sud, and Manongarivo.^[1] The Mandritsara Window separates the Northern from the Central Highlands and apparently acts as a barrier to dispersal between the two highlands, leading to species pairs such as Voalavo gymnocaudus (Northern Highlands) and Voalavo antsahabensis (Central Highlands).^[2] None of the montane endemics of Tsaratanana are shared with the major massifs of the Central Highlands.^[3]
