Join Dr. Stuart Weiss as he discusses how the altered environment of the 21st century has affected two butterfly species, the monarch and the checkerspot. He suggests that simply protecting habitat and hands-off management may no longer be effective.
Overwintering monarch butterflies are now dependent on non-native eucalyptus trees at many sites, which need intensive management to maintain suitable micro-climates over coming decades. Bay checkerspot butterflies depend on grazing cattle to maintain their open grassland habitat in the face of nitrogen fertilization from air pollution. These two butterflies highlight the needs for flexible pragmatic thinking if conservation is to succeed.
