Who We Are

Through a collaborative partnership led by Open Space STL, the Community Stewardship Alliance (CSA) is a conservation program intended to provide focused, trained volunteer leadership to restore and maintain Greensfelder Park. We welcome Larry Lazar as our newest Ambassador to the CSA program! Join us for an event, meet our site ambassador, and learn more about how you can become part of the team

Greensfelder Park is one of the most natural and scenic parks in the St. Louis region. Spanning over 1,700 acres in the rugged foothills of the Ozark Mountains, it is a popular destination for hiking, biking, trail running, camping, equestrian activities, and nature enthusiasts.

The park is largely free of invasive species, although there are some “hot spots” where honeysuckle bushes have begun to take hold. Additionally, in a newly added section closer to the residential areas of Eureka, invasive grasses such as Japanese Stilt Grass, Johnson Grass, and Sericea Lespedeza are dominant.

The proposed CSA activities would work to accomplish three primary goals:

  1. Control and eradicate honeysuckle

  2. Manage and reduce invasive grasses

  3. Restore grassy areas to good health, dominated by native species

There are many opportunities for stewardship projects, including invasive plant removal, native planting, and more. Click here for more information on Greensfelder Park.

What We Do

For The Environment

CSA projects at Greensfelder County Park will include:

  • Invasive species management - Whether it be bush Garlic mustard, bush honeysuckle, Callary pear, or non-native thistles, battling invasive species is a constant, ongoing challenge in our parks and public spaces. If you're interested in protecting our natural communities and the animals that rely on them, consider joining us for one of our invasive species removal projects at the park. 

For The Community

CSA projects at Greensfelder County Park benefit:

  • Community members and volunteers by helping to create lasting relationships that empower local friends and neighbors while bringing people together who value this community treasure and want to see it sustained and thrive.
  • Park & trail users by improving the landscapes and beautifying the park for everyone who enjoys these outdoor spaces for recreation.
