Successful reintroduction of Peganum harmala to Nicosia old walls, Cyprus
24 May 2019
Peganum harmala occurs in Southeaster Europe, Mediterranean region and to the east towards central Asia and northwest India. It is a perennial species, flowering from May to June and fruiting from May to August. In Cyprus, it was recorded only at one location, near the walls of the old city of Lefkosia, on waste ground. It is classified as “Critically endangered” in the Red Data Book of the Flora of Cyprus. The only population of the species was extinct probably due to the heavy use of herbicides in the area.
Within the framework of the CARE-MEDIFLORA project, the species was reintroduced to Nicosia old walls. Seeds were collected from plants originated from Nicosia area and conserved at Athalassa Botanical Garden. Fifty-six plants were planted in April 2017. Two years after (May 2019), fifty mother plants survived (89% survival rate). One year after the successful completion of the first growing cycle of the mother plants, young seedlings have been recorded. The control of noxious weeds is identified as the critical element for the long term survival of the species at the area.
