Iowa Sets Goal for Monarch Conservation

“The consortium has worked collaboratively with diverse stakeholders to develop a comprehensive plan to expand habitat on our agricultural land, urban areas, roadsides, and other public land. We appreciate the many partners that have been involved and are encouraged by the work already underway,” said Mike Naig, Iowa Secretary of Agriculture.

The updated Iowa Monarch Conservation Strategy seeks to establish approximately 480,000 to 830,000 acres of monarch habitat by 2038.

The strategy — developed by the consortium members — guides the implementation and documentation of a voluntary, statewide conservation effort based on the best available science. The consortium is a group of 40 organizations, including agricultural and conservation associations, agribusiness and utility companies, universities and county, state and federal agencies.

Iowa’s habitat goals are included in the Mid-America Monarch Conservation Strategy draft, released by the Midwest Association of Fish and Wildlife Agencies on March 12, 2018. The Mid-America strategy draft describes how the North Central states in the monarch’s northern breeding grounds will collectively establish 1.3 billion new milkweed stems over the next 20 years. Iowa’s strategy estimates 127 to 188 million new stems will be established within Iowa.

“Iowa falls entirely within the monarch’s northern breeding core. This means that every patch of milkweed habitat added in Iowa counts, and Iowa is perfectly situated to lead the way in conservation efforts for the monarch butterfly,” said Chuck Gipp, director of the Iowa Department of Natural Resources. “The recovery cannot succeed without Iowa.”

Female monarchs lay eggs exclusively on milkweed plants so national efforts focus on establishment of new milkweed stems for conservation goals. However, habitat plantings are expected to include a diverse array of nectar species to provide forage for adult monarchs throughout their life cycle and seasonal migrations.

“Recent research demonstrates that an ‘all hands on deck’ approach is necessary for successful monarch conservation. The dominance of agriculture within Iowa means that agricultural land must be a part of the solution,” said Joe Colletti, interim endowed dean of the College of Agriculture and Life Sciences at Iowa State University. “This means that consortium members are looking at all options on agricultural and non-agricultural lands for adding habitat including augmenting existing conservation practices, establishing habitat patches in underutilized, grass-dominated areas, and adding habitat in urban locations such as parks, industrial and school properties.”

The monarch population has declined by more than 80 percent during the last 20 years in North America.  Surveys of the 2017-2018 overwintering generation of monarchs indicate the numbers are still less than half of the size needed to ensure a sustainable population.

The U.S. Fish and Wildlife Service has until June of 2019 to determine whether the monarch should be listed under the Endangered Species Act. The consortium seeks to demonstrate how voluntary efforts can support species recovery and avoid the need to list the monarch.

The Iowa Monarch Conservation Consortium formed in 2015 in response to monarch population declines. More information about consortium is available at www.iowamonarchs.info.
