Great Rivers is a chapter in the Missouri Master Naturalist™ program. This program, sponsored by the Missouri Department of Conservation and the University of Missouri Extension, is designed to engage Missourians in active responsible stewardship of our state's natural resources through science-based education and community service.

The Chapter's objectives include:

  • Improve public understanding of natural resources, ecology, and management by developing a pool of local knowledge about natural resources and ecology that can be used to enhance education efforts within local communities.
  • Enhance existing natural resources, education, and outreach activities by providing natural resources training at the local level, thereby developing a team of dedicated and informed members.
  • Develop a self-sufficient state-wide Missouri Master Naturalist™ volunteer network. This network is dedicated to preserving, maintaining, and restoring Missouri's natural ecosystems and educating others about the positive benefits gained through responsible stewardship of our state's natural resources.


The first Missouri Master Naturalist™ chapter in the greater St. Louis region was the Confluence Chapter. This chapter was established in the fall of 2005 upon the graduation of the area's first Master Naturalists from classes at Busch Wildlife Area in St. Charles County.

With each graduating class the Confluence Chapter grew. In response to the increasing size of the chapter and to better serve the Confluence members from the St. Louis City, St. Louis County, northern Jefferson and eastern Franklin counties a new Chapter was formed; Great Rivers.

The Great Rivers Chapter was established in June 2007. Meetings are held at the Kirkwood Community Center in Kirkwood, MO. Additionally, the Great Rivers Chapter meets for a Summer Picnic and a Winter Holiday Party in lieu of a regular chapter meeting.
