In landscape ecology the analytical base of vegetation contains a map of real or potential vegetation. There exists a map of potential vegetation of the whole territory of Slovakia at scale 1:200 000 but it is always necessary to make the map of real vegetation. From the aspect of time and professional abilities it is a very difficult task and therefore it is often substituted by the map of secondary landscape structure where only basic vegetation formations are usually mapped. Since 1970s original interpretation procedures were developed and also several regions were mapped in Slovakia. However, at present, the botany is again applied without the experts - botanists, because it is quicker and cheaper - to the detriment of vegetation.
