Prangos ferulacea (L.) Lindl is a perennial plant that besides fodder and medicinal values the plant can help to control soil erosion. There is little knowledge about the effect of climate change on the Prangos genus especially P. ferulacea. In this study, we used ensemble modeling based on five species distribution models to predict the potential effects of climate change on the future geograp...
