The protected flora of long-established cemeteries in Hungary: Using historical maps in biodiversity conservation.

The role of anthropogenically influenced habitats in conserving elements of the original wildlife has increased worldwide simultaneously with the disappearance of natural sites.

However, little is known about the occurrence and factors influencing harvesting of salep in graveyards.
