The conservation group Monarch Watch has designated the UW Oshkosh campus as a Monarch waystation since 2015. This is because UWO’s campus grows large amounts of milkweed, a plant crucial to the livelihood of Monarchs.

The Monarch has several broods each summer in Wisconsin, the last of which is typically headed south by October, creating a spike in their presence from August to October as they prepare for their long journey south to Mexico.
