Overharvesting to meet skyrocketing demand in Turkey and elsewhere is placing the endemic wild orchid population in Pindos, northwestern Greece at risk, according to a team of scientists studying the flowers. A key ingredient for the production of salep, a popular sweet drink, and Turkey's mastic ice cream dondurma, the dried orchid is now fetching prices as high as 90-120 euros per kilo on the black market.
A researcher at the Ioannina University's Biological Applications and Technologies Ecology Laboratory, she is working with Martha Charitonidou, Anastasia Tzortzaki and John M. Halley to study the impact of harvesting on the orchid population, a project that is part of the Operatonal Programme 'Development of Human Resources, Education and Life-long Learning 2014-2020'.
The team is focused on the orchids Dactylorhiza sambucina and Orchis mascula ssp. mascula, which are the two types most commonly collected for salep production in Greece. The first is relatively common in Greece and its population is mainly affected by the available open spaces and nearby species, as well as proximity to roads, grazing and overharvesting, she said.
According to Stara, traditional orchid collection in the 60s was done by hand, using a specially-made small adze, and was a tiresome job that few elected to do. Harvesting started in June when the flowering season was over and harvesters would replace the old bulbs in the soil so they would find more the following year.
While ornamental orchids can be cultivated, the same was not true of wild orchids, whose reproductive biology was more unusual, she pointed out.
"Orchids are directly dependent on their symbiosis with fungi that live in the soil and support their development in the first stages of life, something that makes their cultivation difficult. In spite of this, many research efforts are underway in Turkey, Greece and elsewhere in Europe," she said. According to Stara, finding ways to cultivate the plants is the sole solution for their protection, while she underlined the urgent need to finds ways to sustainably manage wild plants in Greece that are the focus of great commercial interest.
