Resumé :
A bioclimate model predicting the presence of Abies religiosa, host for 
overwintering Monarch butterfly migratory populations inside the Mexican 
Monarch Butterfly Biosphere Reserve (MBBR), was developed for 
contemporary and future climates (years 2030, 2060 and 2090). Results 
suggest that the area occupied by the A. religiosa niche should diminish 
69 % by 2030, 94 % for 2060, and 97 % for 2090, and suitable habitat may 
no longer occur inside the MBBR by 2090. That would induce a severe 
forest declination that likely will decimate the unique winter refuge 
for Canadian and USA migratory Monarch butterfly populations. Signs of 
forest decline are being observed already. We suggest conducting 
assisted migration of A. religiosa, shifting altitudinal upwards at 
least 275 m to match climate predicted for 2030, and establishing A. 
religiosa new populations outside the MBBR, using Lupinus sp. as nurse 
plants to protect the seedlings against frost damage.
