Ecological parameter: LANDOLT Bryophytes - light Switzerland (Alpine region)

Parameter group: habitat related parameters

Explanation:
The light value of a species indicates the average light quantity received in the respective habitats. Species with high light values particularly grow in places with full light and species with low values are found in the shade. Values for trees and shrubs refer to the shade tolerance of seedlings and saplings.
