Global Mountain Biodiversity Assessment (GMBA)

A hierarchical inventory of the world’s mountains for global comparative mountain science


ACCESS the latest version of the GMBA inventory v2 on EarthEnv

This new release, introduces a hierarchical classification of the mountain ranges of the world, which allows for the partitioning of mountain systems into smaller ranges and subranges and enables spatially explicit and comparative mountain research across scales.


The construction of the mountain range polygons is the result of a semi-automated approach, where rivers form the borders between contiguous mountain ranges and the outer borders of the mountain systems correspond to a new, more generalized mountain definition. Details on the polygon delineation and additional information are available in Snethlage et al. (2022).
