Research is limited on the effects of climate change on the distribution, productivity or availability of medicinal plants , but some are facing threats due to climate change . Climate change is projected to impact some medicinal plant species through changes in temperature, precipitation, pests and pathogens; unsustainable harvest of high-value species will significantly exacerbate these impacts  . Table 5.9 highlights that climate change impacts on medicinal plant species will vary greatly by species. Medicinal plants that grow in arid environments are also highly susceptible to climate-induced change . Arctic medicinal species may also be particularly at risk due to climate change .
