Monarch Butterfly Biosphere Reserve News Archive

Letters From The Field

Thanks to Ms. Estela Romero and Dr. Ellen Sharp, Journey North is able to bring our readers news about monarch butterflies from the Monarch Butterfly Biosphere Reserve (Mariposa Monarca Biosphere Reserve) in Mexico. These Letters From The Field herald the arrival of millions of monarchs to their overwintering habitat in the high altitude forests situated within the states of Mexico and Michoacán. From October to February, Ms. Romero and Dr. Sharp provide first hand observations of monarch behavior within Sierra Chincua, El Rosario and Cerro Pelon Sanctuaries. These writers share stories from the community, stories that tell of the challenges and opportunities as well as joys and responsibilities of living in close proximity to an internationally recognized world heritage site.

Every week, starting in mid-October, Estela Romero writes articles describing monarch activity within the Monarch Butterfly Biosphere Reserve. Ms. Romero’s articles focus on Sierra Chincua and El Rosario Sanctuaries. 

As an experienced environmental educator, Ms. Romero works with other educators and students in communities surrounding the Monarch Reserve. She delivers educational programming as well as Symbolic Migration Classroom Ambassadors to local schools. Ms. Romero describes these school visits in her weekly blog posts for the Symbolic Migration Project.

During the 2020-2021 overwintering season, Dr. Ellen Sharp, co-owner of JM Butterfly B&B and Ecotours and co-founder of Butterflies & Their People, generously shares observations from the Cerro Pelon Monarch Butterfly Sanctuary. Due to the pandemic, the Cerro Pelon Sanctuary closed to outside visitors. Dr. Sharp and Forest Guardians at the Cerro Pelon Sanctuary will provide glimpses of monarch happenings in this region for the Journey North community. More of Dr. Sharp’s writings are available at
