The Electric Power Research Institute (EPRI) worked with the Xerces Society for Invertebrate Conservation to develop this report, which synthesizes the scientific literature and existing best management practices for monarch butterflies along with input from a survey of monarch experts and a survey of EPRI members. Monarch experts were surveyed to identify the relative benefit of specific conservation actions for monarchs as well as to provide opinions on the opportunities for power companies to engage in monarch conservation.
It can be difficult to establish native milkweeds in the western states. The Xerces Society partnered with USDA Natural Resources Conservation Service Plant Materials Centers to find the best methods for planting and growing two widespread species, showy milkweed and narrow-leaved milkweed. This fact sheet presents the information learned from these trials.
