Service Description: The natural assemblage species indicator is a forest indicator. This is a proxy for measuring the congruency between the potential and current tree species distribution. The natural assemblage indicator is considered a key indicator in the evaluation of HNV forest area indicator (EEA, 2014). The dataset values express, in the fuzzy values between 0 and 1, the percentage of tree species vegetation agreed with potentially dominant tree species by pixels. The values close to 1 mean high percentage of native tree species (natural) whereas values close to 0 are an approximation of a low level of naturalness, being a high percentage of non-native species.

Description: The natural assemblage tree species indicator is a forest indicator. This is a proxy for measuring the congruency between the potential and current tree species distribution.
The dataset values express, in the fuzzy values between 0 and 1, the percentage of tree species vegetation agreed with potentially dominant tree species by pixels. This measure is independent of the current forest coverage. The values close to 1 mean high percentage of native tree species (natural) whereas values close to 0 are an approximation of a low level of naturalness, being a high percentage of non-native species.
