The reason for Entlebuch’s high level of biodiversity (i.e. species diversity) is its closely intertwined mosaic of habitats which provide many plant and animal forms with a home in the region. For example, very dry and alkaline karst habitats interlink with very wet, acidic moorland habitats within a very small area. The Napf region of Entlebuch also has many special types of forest. The rough pastures and meadows at high elevations are particularly species-rich as they are extensively cultivated.
