Milkweeds, monarchs and pollinators in a changing climate | Desert Botanical Garden

OPEN DAILY 8 A.M.|7 A.M. FOR MEMBERS WED. & SUN.

As monarch butterfly populations experience declines of up to 99%  across the United States, and essential host milkweed habitat is lost to urbanization, critical conservation choices need to be made about these species and their interactions. At the DPEL, staff explores how the functional relationships between milkweeds and the insects that utilize them may be impacted as the Southwest gets warmer and drier. The goal is to increase understanding of these impacts that in turn will guide conservation decisions into the future.
