About the Program
The BASF Hannibal agricultural chemical production facility is located in Palmyra, Missouri, just north of Hannibal and two hours northwest of St. Louis at the confluence of the South River. It sits adjacent to the Mississippi River and is surrounded by open agricultural fields. As part of their corporate commitment, BASF established the “Living Acres” initiative, a research-driven effort wherein they recognize that the vast majority of monarch butterfly reproduction occurs in the northern-central region of the United States, known as the “Corn Belt”, and that land not used for crops could support milkweed communities without interfering with agricultural production. Living Acres focuses on protecting monarch habitat and increasing biodiversity.  BASF Hannibal has dedicated a 5000 square foot landscaped garden to aid in its research focused on providing habitat for all life stages of the Monarch Butterflies on non-crop areas of farmland.

Practices and Impacts

  • A pollinator garden was created in 2017 to support the monarch butterfly by establishing a no-mow zone and planting a variety of native, pollinator-supporting plants with guidance from a local native plants nursery.
  • Monitoring notes are collected about generally vegetation growth condition once a month during growing season; with plants in bloom, invasive species present, pollinator species, and other signs of wildlife (e.g. coyote scat) noted.
  • A perimeter fence was installed to the area in 2020 to prevent the plants from being over-browsed or mowed.
  • Late June 2020 effort included manual/hand removal of non-native and invasive plant species installation of new fences and perimeter rope that can be moved to expand the garden.
  • 50 plants of six additional plant species, including Spider Milkweed, arrived on site to be prepared for installation in the newly cleared garden area.
