How accurate is the data used about how many medicinal and aromatic plants are supplied from the wild, how many are cultivated (or both), which plants are classified as threatened species in some regions, which are not (or are not yet assessed)? In this webinar Josef Brinckmann and Wolfgang Kathe will discuss the findings in their recent article updating estimates on medicinal plant species in cultivation and their conservation status. They will also discuss what it took to retrieve and compile this data, its limits, and why, more broadly, accurate data matters.
