Letters From The Field describing overwintering monarchs at the Monarch Butterfly Biosphere Reserve are coming to a close.

Our contributors, Dr. Ellen Sharp, Ms. Anna Moreno, Mr. Pato Moreno, and Ms. Estela Romero have provided rich stories from the monarch sanctuaries in the States of Michoacán and Mexico, in central Mexico. Estela will write a few more articles before we say farewell for the overwintering season in Mexico. Throughout the spring, summer and fall, you can catch up on news you may have missed.

Targeted Project: Monitoring Overwintering Monarchs

A heart-felt THANK YOU goes out to all those who participated in the targeted study of monarchs in the Gulf states of Texas, Louisiana, Mississippi, Alabama, and Florida as well as Georgia, South Carolina and North Carolina. Journey North will share your submitted reports to researchers and others studying monarch behavior in this region. We hope to replicate this monitoring effort next year. (This project was a collaborative effort among Journey North, Monarchs Across Georgia, the University of Georgia and the Georgia Department of Natural Resources.)
