Determinate the total forest surface occupied by butterflies
colonies in Mexico to establish the priority habitat.
Method: colonies localization and measurement

Conclusions:
1. We must continue with the monitoring program for the overwintering Monarchs in
Mexico
2. We have a real big problem with the declining of Monarch population,
3. In the Monarch Reserve; We have a real important information about the habitat
use by Monarchs and we´re going to use that to conform the next Management
Plan,
4. We need connect all monitoring programs to have a integrated analysis and point
of view,
5. WE NEED TO INCLUDES IN OUR PROGRAMS THE ADAPTATIOS TO
CLIMATE CHANGE ,
“THE CLIMATE CHANGE IS NOT AFECTING ONLY TO THE MONARCHS, IT’S
AFECTING TO US “THE HUMAN BEING”
