The main threats are posed by natural catastrophes such as landslides or factors such as erosion. This plant also suffers from competition with native flora (Commission of the European Communities 2009) and exotic flora (Jardim et al. 2006). There is also a major threat that arises from fires such as the one in summer 2010 that affected the Central Mountain Massif (J.A. Carvalho, unpublished data).
