The symbols are placed on the map in the order black, red to cyan, except for Reversed order and Red-list category where the order is black, cyan to red, and Herbarium where they follow database index order.

 NLD reads this file to get the red list category for each species.

Hot Spots: The sum of rarety index values for each species recorded (collected or noted) at each locality (see locality definition below) per grid cell. The rarety index value is defined as the inverse of the number of Norwegian localities for a given species, calculated for the 25% most rare macrolichen species. The value is set to zero for the remaining species. NLD generated this file of rarety index values at the latest update.
Species richness: The number of species recorded per grid cell.
Collections: The number of separate species-locality-date records per grid cell. E.g., one species collected at two separate dates at the same locality is counted as two, whereas two collections of the same species at the same locality and date are counted as one.
Localities: The number of localities recorded per grid cell. A locality is defined as a 1×1 km square in UTM zone 33 where there at least one collection or field note has been made.
Field days: The number of dates with at least one collection of field note recorded per grid cell.
