  • Monarchs: the DeRoode Lab Research and how to have a healthy habitats – Dr. Jaap DeRoode
  • Closing remarks


Karen Oberhauser

Director, Arboretum; Professor, Dept. of Entomology

University of Wisconsin – Madison

Monarch butterfly populations have been declining over the last 20 years. Because insect numbers are notoriously difficult to assess, and because they often show large annual fluctuations, simply documenting this decline has been a challenge. It is now important to move beyond simple documentation, and toward responding to the challenge posed by monarch conservation, and insect conservation in general. Karen will describe the amazing biology of migratory monarch populations, how citizens and scientists are documenting monarch numbers across their migratory cycle, and then discuss what all of us can do to help preserve this charismatic insect for generations to come.


Dr. Jaap de Roode

Professor of Biology; Emory University Biology Department
Director, Infectious Disease Across Scales Training Program (IDASTP); Co-Director, From Molecules and Pathogens to Populations and Pandemics (MP3); Member, Board of Directors, Rosalynn Carter Butterfly Trail®
