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

A standardized delineation of the world's mountains has many applications in research, education, and the science-policy interface. Here we provide a new inventory of 8616 mountain ranges developed under the auspices of the Global Mountain Biodiversity Assessment (GMBA). Building on an earlier compilation, the presented geospatial database uses a further advanced and generalized mountain definition and a semi-automated method to enable globally standardized, transparent delineations of mountain ranges worldwide. The inventory is presented on EarthEnv at various hierarchical levels and allows users to select their preferred level of regional aggregation from continents to small subranges according to their needs and the scale of their analyses. The clearly defined, globally consistent and hierarchical nature of the presented mountain inventory offers a standardized resource for referencing and addressing mountains across basic and applied natural as well as social sciences and a range of other uses in science communication and education.

Automated summary

This article introduces a global mountain range inventory developed under the auspices of the Global Mountain Biodiversity Assessment, which aims to achieve standardized delineation and transparency of mountains. The inventory provides a clear definition and hierarchical structure, and can be applied in various fields such as research, education, and science communication.
