Insects rely on plants for survival. Desert Botanical Garden seeks to understand how native plants support local butterfly populations. To increase impact, the Garden combines research with native propagation and outreach efforts, under the umbrella of Great Milkweed Grow Out.

Kim Pegram, Ph.D.
Program Director, Pollinator Conservation and Research
I manage pollinator and butterfly conservation initiatives and research at the Garden. The Garden’s primary pollinator initiative, Great Milkweed Grow Out, helps conserve monarch butterflies and other pollinators in Arizona by propagating and distributing thousands of native milkweeds, outreach into the community and researching how insects interact with milkweed. My current research seeks to determine 1) which native milkweeds are best for monarch conservation, 2) how milkweeds support other beneficial insects and 3) butterfly-hostplant ecology in other species. My PhD research focused on warning coloration, understanding how iridescent blue can function to warn predators, with pipevine swallowtail butterflies as a model.

PhD. Biology, Arizona State University/Desert Botanical Garden (In progress)
Melkonoff’s work is focused on the interactions between plants and animals and how the physiological processes of both impact their interdependence on one another and their ability to thrive under different environmental stressors. She is currently working on her Ph.D. with a focus on the interactions between milkweed, monarch butterflies and pollinators in the Sonoran Desert. She also coordinates Desert Botanical Garden’s monarch and pollinator conservation initiative, Great Milkweed Grow Out.
