Louisville/Jefferson County Metro Government

Louisville, KY

Craig Greenberg


Pledge Summary

Founded in 1778, the City of Louisville is the largest city in the Commonwealth of Kentucky and sits on the banks of the Ohio River. Mayor Craig Greenberg is continuing Louisville’s support and is joining over 600 fellow mayors across the U.S. in support of monarch butterfly and pollinator conservation by signing the National Wildlife Federation’s “Mayor’s Monarch Pledge”. With the monarch butterfly population declining by 80% over the last 20 years, and the 2023-2024 overwintering population in Mexico reaching the second lowest level ever recorded, the monarch butterfly has emerged as an ambassador species to raise awareness for all pollinators and ecosystem health about their need for milkweed plants as well as other native wildflowers and grasses that provide nectar for food and habitat. Mayor Greenberg is dedicated to environmental health by supporting sustainable monarch conservation efforts through encouraging, educating, and empowering citizens that their efforts to create more pollinator habitat throughout the community can have a lasting impact on wildlife and human health. The Louisville Zoo is an accredited member of the Association of Zoos & Aquariums (AZA) and an agency of the Louisville Metro Government. The Louisville Zoo is also partner of the AZA’s Saving Animals From Extinction (S.A.F.E.) North American Monarch Butterfly Program.

Community Spotlight

Action Items Committed for 2024

Communications and Convening

  • Issue a proclamation to raise awareness about the decline of the monarch butterfly and the species’ need for habitat. This proclamation must incorporate a focus on monarch conservation.
  • Launch or maintain a public communication effort to encourage residents to plant monarch gardens at their homes or in their neighborhoods. (If you have community members who speak a language other than English, we encourage you to also communicate in that language; Champion Pledges must communicate in that language.)
  • Engage with community garden groups and urge them to plant native milkweeds and nectar-producing plants.
  • Engage with gardening leaders and partners (e.g., Master Naturalists, Master Gardeners, Nature Centers, Native Plant Society Chapters , other long-standing and influential community leaders) to support monarch butterfly conservation.
  • Create a community-driven educational conservation strategy, initiative, or practice that focuses on and benefits local, underserved residents.

Program and Demonstration Gardens

  • Host or support a native seed or plant sale, giveaway or swap.
  • Plant or maintain a monarch and pollinator-friendly demonstration garden at City Hall or another prominent or culturally significant community location.
  • Add or maintain native milkweed and nectar-producing plants in gardens in the community.
  • Host or support a monarch butterfly festival that is accessible to all residents in the community and promotes monarch and pollinator conservation, as well as cultural awareness and recognition.
