Érdekesebb florisztikai adatok egy nyírségi ruderális élőhelyről
Regular floristic and coenological survey of an abandoned goose-breeding farm at village Vámospércs resulted in some uncommon records. Appearance of Ceratocephalus testiculatus, Consolida orientalis and Pholiurus pannonicus was surprising on sand. Their presence suggests unintentional introduction by transporting the animals and their fodder from the Hortobágy. Chamaenerion angustifolium may have established from an unknown forest or clear-cut locality. Presence of all species was temporal between years 1990-93.
