Low-growing vegetation aids butterflies, keeps rights-of-way compatible

Transmission line corridors in central Wisconsin are prime habitat for the federally endangered Karner blue butterfly.

The larvae of these butterflies feed only on wild lupine plants, severely restricting where they can survive. We are among a group of more than 30 public and private landowners working to protect the species through habitat conservation plans.

Common milkweed is an additional species of vegetation that ATC advocates for and plants in our rights-of-way. Milkweed provides the depleting Monarch butterfly population with their primary food source. Check out the Grow Smart planting guide for suggestions on additional low-growing options that help the pollinators and keep the vegetation compatible within the rights-of-way.
