Justification of Red List category
This species is declining at a moderately rapid rate, qualifying the species as Near Threatened. Declines in the core population in Spain are largely responsible for overall declines. The drivers of this decline are not entirely clear but include habitat degradation and modification. Should the population be found to be declining more rapidly, the species would warrant uplisting to a higher threat category.
