About IC Monarchs

Monarch butterfly populations have declined by more than 90 percent in the past two decades.

Iowa City is committed to creating an environment that will allow monarchs to thrive and rehabilitate during the summer months, and is taking several steps to help support the monarch butterfly.

Local Monarch Initiatives 

Milkweed Distribution 

A key action in Iowa City is the planting of milkweed to help combat the declining population of monarch butterflies. 

Monarchs lay their eggs in milkweed during the summer months. When the caterpillars hatch they eat the leaves. The City of Iowa City has planted its own milkweed, while also giving away common milkweed for people to place in their own yards and gardens to help the monarchs.

The City also supports monarch waystations that provide milkweed for monarchs at Wetherby, Hickory Hill and Hunter's Run Parks as well as the Eastside Recycling Center

Mayor's Monarch Pledge 

Iowa City Mayor Jim Throgmorton signed the National Wildlife Federation's Mayors' Monarch Pledge on Tuesday, Aug. 16, 2016 to help raise awareness about declining Monarch populations. This pledge indicates a commitment from the City to help rehabilitate the Monarch population.

Local Monarch Research 

A team of students from Cornell College in Mount Vernon is conducting research at Waterworks Prairie Park in Iowa City.

They are working to understand how prairies and monarch butterflies interact. Dr. Tammy Mildenstein, of Cornell College, has designed a research program to learn about the relationship between prairie and monarch reproductive success. The goal is to provide managers and caretakers of parks, prairies and other outdoor spaces with research findings to increase suitability of milkweed populations for monarch reproduction and survival. With careful observation and thoughtful land stewardship, the team aims to revitalize the iconic monarch butterfly population.
