Population justification: Different surveying methods identification have made population estimates difficult. However, three surveys in 2001, 2002 and 2007 indicate a population of between 217 and 304 individuals, hence the population is best placed in the band 50-249 mature individuals.
Trend justification: Standardised surveying methods reveal a decline from 304 individuals in 2001 to 217 individuals in 2007 (ECOAN 2009), hence the population decline is estimated to be 30-49% over the past 10 years (three generations).
