In 2019, MBF funded the update and publication of the “Monarch Cartographic Series: Vegetation and Land Cover 2018” and it is now online on UNAM’s Center for Research in Environmental Geography (CIGA)’s website. Developed by board member Isabel Ramírez, and her collaborators Jairo G. López-Sánchez and Sara Barrasa, this update is the second part of the Monarch Cartographic Series of which Volume 1 was published a decade ago and both are part of a long-term monitoring project of land cover in the Monarch Butterfly Biosphere Reserve (MBBR) and its surrounding areas. The monitoring will allow us to identify the magnitude and location of changes in land use.
