The 320-acre Rock Run Preserve was acquired between 1990 and 2009.

The preserve is part of the Rock Run preservation system, which conserves more than 1,450 acres of land.

A 168-acre portion of the site was registered as an Illinois Land and Water Reserve in 2003 and 2005. This registration provides permanent protection for the natural resources at the preserve.

Paul V. Nichols Access is one of two access areas to the preserve. The other access area is Black Road Access in Joliet.

Rock Run Preserve protects a diversity of habitats, including forest, prairie, wetland, and a portion of Rock Run.

The preserve is also home to more than 500 plant species, including the violet, buttercup, mint, and aster.

The site is managed with invasive species control, prescribed burning, and community restoration to protect and enhance its natural resources. Learn more about the District’s land management activities.
