All rat data are interventions, not occurrences: no presence absence information

There should be a field Materiaal_consumptie -> then it's definitly a management interaction, unless it's bak buis, those are always a management intervention.

It's possible if you do a management interaction that you don't see a rat, it could be a trail or a mark. If the poison is not eaten, the status should change to afgewerkt en afgesloten. But it is really more complicated:

On private land, they only go once, explain what they have to do, startup with vermin, and then they have to do it themselves, so then we don't know what happened next.
