Figure 13. Western Monarch Thanksgiving Count Data 1997-2013. From Monroe et al. 2014 An analysis of the 17 western <strong>monarch</strong> overwintering sites that have been monitored every year shows that there has been a statistically significant population decline (Griffiths and Villablanca in preparation). There is evidence that a range contraction has also occurred, with significantly more sites declining at the southern and northern extremes of the <strong>monarch</strong>’s winter range (Griffiths and Villablanca in preparation).
