Justification:
A study by Perdices and Doadrio observed a decline in population of C. calderoni of over 70% in the past 10 years, declines in area of occupancy (AOO) and extent of occurrence (EOO) have also been observed due to gravel and water extraction and introduced species are also having a negative impact. This decline is suspected to continue into the future at the same rate (Carmona, J. pers comm).
