Setting the Table for a Regal Butterfly Comeback, With Milkweed
It was a pod that, after a gentle squeeze, burst with chocolate brown buttons: seeds of milkweed, the favored indeed, the only food of the monarch butterfly caterpillar.
Once wild and common, milkweed has diminished as cropland expansion has drastically cut grasslands and conservation lands. Diminished too is the iconic monarch.
Dr. Jackson, a University of Northern Iowa biologist and director of its Tallgrass Prairie Center, is part of a growing effort to rescue the monarch. Her prairie center not only grows milkweed seeds for the states natural resources department, which spreads them in parks and other government lands, but has helped seed thousands of acres statewide with milkweed and other native plants in a broader effort to revive the flora and fauna that once blanketed more than four-fifths of the state.
Nationwide, organizations are working to increase the monarchs flagging numbers.
