BiodiverseCity St. Louis


About BiodiverseCity St. Louis


On May 15, 2013, community stakeholders with a shared interest in urban biodiversity participated in a summit held at the Missouri Botanical Garden. This Summit celebrated the existing efforts and projects already underway across the St. Louis region to promote and protect biodiversity, while also identifying critical gaps and needs in the areas of biodiversity understanding, awareness, and willingness/incentives to act.

Summit participants urged the development and implementation of a regional biodiversity initiative. It is in this spirit that BiodiverseCity St. Louis — a community initiative to promote, protect and plan for biodiversity throughout the Greater St. Louis Region — will shape its priorities and programs. Learn more.

BiodiverseCity St. Louis calls for everyone in our shared community — city governments, corporations, non-profit organizations, universities, schools, scientists, concerned citizens, homeowners, families and community leaders — to be inspired and take action. Take the pledge!
Project Profile

Milkweeds for Monarchs:  The St. Louis Butterfly Project

On Earth Day 2014, Mayor Slay announced the launch of a new initiative designed to foster the connection between people and urban natural resources. Milkweeds for Monarchs: The St. Louis Butterfly Project is an initiative out of the Mayor's Sustainability Action Agenda.

The first year goals are to create 250 monarch butterfly gardens throughout City neighborhoods and community spaces, so that more people will have the opportunity to experience butterflies in the City. Mayor Slay has committed that the City will plant 50 monarch gardens, and is challenging the community to plant an additional 200 monarch gardens in 2014 to commemorate our 250th birthday year.

In partnership with community plant and butterfly experts, the City has created a STL Monarch Mix brochure to serve as a reference in establishing your monarch garden. These plants have been carefully selected to provide the best combination of features for the butterflies and your personal enjoyment. These plants were chosen to flower at different times of the growing season, offering seasonal color and important butterfly food and nectar sources. Learn more.
