Worldwide biodiversity is decreasing due to climate and land-use changes. Ecosystems at high altitudes such as subalpine and alpine habitats are particularly threatened. Monitoring is a useful tool to observe biodiversity and its development in space and time. In many cases monitoring programmes are restricted to local scales, being well-adapted for a certain region and the results being interpreted thoroughly for that specific site. However, no common platform exists where different approaches may be compared and further developed for (sub)-alpine-nival monitoring sites in Europe.
