Threats to populations of Corallium rubrum include water temperature anomalies, over-harvest, and destructive fishing practices. During the late summer of 1999, unusually high temperatures may have been the cause of both the mass mortality of the corals and the drastic reduction in settlement of new recruits (Bramanti et al., 2005). The popularity of Corallium rubrum in jewelry has resulted in the unsustainable harvest of easily accessible populations (Santiangelo & Abbiati, 2001; Oral, 2010). In addition, fishing practices like trawling damage or destroy the coral (Oral, 2010).
