Time series of monarch butterfly overwinter abundance in Mexico
Detailed Description
Zylstra and colleagues (2021) published a re-analysis of historical studies of monarch butterfly overwinter abundance, predicting a time series of historical abundance for monarch butterflies before systematic surveys began. For more information, see Zylstra, E. R., W. E. Thogmartin, M. I. Ramírez, and E. F. Zipkin. 2020. Summary of available data from the monarch overwintering colonies in central Mexico, 1976–1991: U.S. Geological Survey Open-File Report 2020–1150, 10 p.

The Challenge Over the last two decades, the Eastern migratory population of monarch butterflies has declined by about 80%, leading many scientists to consider how to best conserve and rebuild monarch populations. Conservation efforts can be challenging to design and execute because of the multi-generational migration of monarchs that spans North America. Conservationists must consider many...
