The iconic monarch butterfly, well known for its striking orange-enveloped wings contrasted by black venation, has become an insect of high intrigue across North America. The marathon-length migration the butterfly makes to Mexico to overwinter in the alpine oyamel fir forests inspires wonder and fascination. The biological mechanisms and evolutionary relevance of this journey have become the subject of scientific research, while first sighting of the adults, eggs and caterpillars each year draws excitement from community scientists who participate in observation recording.
Recently, the monarch butterfly has garnered even greater attention. News broke on December 15, 2020 that the United States Fish and Wildlife Service (USFWS) had come to a decision on the federal listing status of the monarch butterfly. The Service had been petitioned in 2014 to list the monarch as a threatened species under the Endangered Species Act. Following comprehensive review of the current and future population status of the monarch butterfly, USFWS announced that listing the monarch as threatened or endangered is warranted, but precluded while higher priority listing actions are addressed.
This action results in the monarch becoming a candidate species under the Endangered Species Act. As a candidate species, the status of the monarch butterfly will now be reviewed yearly by USFWS scientists until a listing decision can be made. The monarch will likely stay in the national spotlight for years to come, during which time data collection will continue to assess the population and habitat created or improved for the butterfly.
The Kentucky Department of Fish and Wildlife Resources views the U.S. Fish and Wildlife Service’s decision as an indication of the vulnerable status of the species and as affirmation in the need for continued conservation work for the monarch. Conservation of the species will require efforts throughout the monarch’s range. Here in the state, we are moving forward with work on monarch preservation. Kentucky not only supports the iconic migration of the monarch, but serves as breeding habitat within the butterfly’s range.
Kentucky embarked on creation of the Kentucky Monarch Conservation Plan in 2016 following a targeted national effort surrounding concerns of population-level decline. During this time, garden clubs, native plant groups, and other organizations were already making headway for monarchs in the state. Published in 2018, this plan guides current priorities for monarch conservation, and will continue to do so through potential future changes in the listing status of the butterfly. Kentucky is also a member state in the Mid-America Monarch Conservation Plan, allowing for collaboration with other states across the monarch’s midwestern range to increase habitat. Of primary concern is increasing the number of milkweed stems in the region, which provide the sole food source of monarch caterpillars.
Currently, stakeholders of the Monarch Plan are working to increase habitat, which includes both milkweed and native flowering plants (a source of nectar resources for adult butterflies) on the landscape. There are now 827 Monarch Waystations officially registered in Kentucky, and thousands of acres of habitat have been improved or added for the benefit of monarchs and other pollinators through the enhancement of private, public, and right-of-way land. A variety of educational events and outreach initiatives have been aimed at raising awareness for the monarch in the state, with several hundred monarchs tagged over the course of fall tagging events, over a thousand seed packets distributed, and presentations given in classrooms, during workshops, at club and professional meetings, and most recently, in virtual settings.
Conserving the monarch butterfly has been called an “all hands on deck” approach, with participation from the transportation and agricultural sectors, public agencies, non-government organizations, private businesses, and urban, suburban and rural environments all being important in support of such a widespread species.
Planting milkweed is one of the most important things you can do to help the monarch. If you don’t have a garden, you can aid instead by participating in community science initiatives that track monarchs along their migration route (visit monarchjointventure.org and journeynorth.org to learn about opportunities). Follow us on Facebook at “Kentucky Monarchs” as we share information and links related to monarch butterflies in Kentucky, and remember that no effort is too small to help conserve monarchs!
