With the implementation of the High-Resolution Diversity Monitoring System (Sistema de Alta Resolución para el Monitoreo de la Diversidad—SAR-MOD) in the Janos Biosphere Reserve, monarch butterfly monitoring was decisively carried out in 2016, in the northern Chihuahua region. This work applied the national standardized monitoring protocol.

As part of the results obtained in the first year of monitoring, the presence and passage of monarch butterflies was reported in the grassland zone during the autumn migration, along with certain passage and stopover sites in river zones. Along with the monitoring activities, management at the Protected Natural Area has also fostered capacity building among its community watch corps, where monarch conservation is a priority.
