ID = Identification number of the potential problem area (see the map).
Distance =
 
Distance from the beginning of the STS action zone, km. Negative distance means that the PPA is in the monitoring zone.
N traps = Number of traps in the problem area.
Max catch = Maximum number of moths captured within the problem area.
Max before = Maximum number of moths captured in a 3-km neighborhood in the previous year.
Priority index = Shows the priority for STS action (either treatment or delimiting).
Delimit index = Shows how well the area was delimited in the previous year.
Backgr. moths = Mean log moth counts in a 25-km neighborhood.
