Tinley Creek-Bartel Grassland

Tinley Creek Wetlands and Bartel Grasslands are adjacent properties of the Forest Preserve District of Cook County, and together they comprise one of a handful of large-scale native grassland habitats in northeastern Illinois.


Bartel Grassland and Bobolink Meadow Land and Water Reserves

Since 2008, Openlands has managed restoration at Bartel Grassland Land and Water Reserve and at the newly-designated Bobolink Meadow Land and Water Reserve, which is located at Tinley Creek Wetlands. Both restorations have been a major project for the Next Century Conservation Plan.
The two adjacent sites are both in proximity to Orland Grassland Land and Water Reserve, another legacy project of Openlands, which has created a network of pristine grassland and wetland habitats in southern Cook County. By identifying and restoring conservation areas in proximity to one another like these, we create the habitat on the scale needed for wildlife to thrive.

Openlands provides project management for these sites to restored native grassland. Specific restoration work at the site includes:

  • Coordinating planning and permitting
  • Invasive tree removal
  • Hydrologic restoration
  • Restoration of native plant species
  • Bird monitoring

Additionally, Openlands is working with the Forest Preserve District and Wheeler Kearns Architects to create an interactive interpretive plan for the site. Plan your visit to Bartel Grasslands.
