Remarks on indicator update frequency #91

Marianne Evju: Indikatoren kan oppdateres jevnlig basert på ANO-data, gitt at ANO-feltprotokollen utvides. Vi kan ikke forvente at NiN-data vil kunne bidra i like stor grad til en tidsserie, da pressområder er prioritert i kartleggingen de siste årene, og andre arealer muligens vil prioriteres framover (i.e. data fra ulike tidsperioder vil representere ulike HIF-er).

Added this:

Regarding update frequency, the Nature type data set is not replicated, nor will it be in the future. We must therefore trust that the selection criteria for which areas to survey will not change drastically and systematically over time. For example, we are now surveying a lot in pressure areas, meaning lowland areas close to human population centers. If we in the future allocate more time to surveying wilderness areas, then the indicator becomes biased. On the other hand, ANO is replicated every 5 years.
