About Milkweeds for Monarchs
On Earth Day 2014, former Mayor Slay launched Milkweeds for Monarchs: The St. Louis Butterfly Project to foster the connection between people and urban natural resources where they live, work, learn and play. Milkweeds for Monarchs (overview document here) aligns with the City of St. Louis Urban Vitality & Ecology effort and advances objectives in the City of St. Louis Sustainability Plan. The City commenced the effort by establishing 50 monarch gardens in 2014; most of these gardens are located at fire houses and City parks across the City. The community was challenged to plant an additional 200 monarch gardens to celebrate the City's 250th birthday. The program was expanded in 2015 to reach further into the community and to 50 urban schools, and was expanded in 2016 to launch a St. Louis Riverfront Butterfly Byway along the Mississippi Riverfront.
