Question 4.3

If a species becomes extinct (or undetectable by the monitoring scheme because it is becoming very rare), does it also disappear from an indicator?


No. In such case, the species index decreases to very low values, even to zero. If a species index falls to 5% or below, we set it at 5% and keep it fixed at this value until the index increases again. This is to warrant that this species has an ongoing influence on the indicator and that its disappearance will not be ´forgotten´. Species, to which this rule has been applied, are marked in published results.
