Territorial units used in the checklist

Two main territorial units are used in the checklist:

• Czech Republic (CZ) consisting of two historical parts, Bohemia (B) and Moravia (M) [dotted borderline]

• Slovakia (SK).

The borderlines do not follow the mountain ridges and river meanders; they are smoothed for the purpose of this checklist. As figured in the map, they do not represent the editors' view and/or claims.
