The Conservation Foundation
Non-Profit

Simply put, we save land and we save rivers, and we’ve been at it for more than 50 years. Founded in 1972, The Conservation Foundation is one of the region’s oldest and largest not-for-profit land and watershed conservation organizations dedicated to preserving and restoring open space, protecting rivers and watersheds and promoting stewardship of the environment in northeastern Illinois. We focus our work in DuPage, Kane, Kendall and Will Counties, but have also had the honor of working on significant projects in Cook, DeKalb, Grundy and LaSalle Counties.

IRS Financial Data
Summary: Over the past decade The Conservation Foundation has grown its asset base from about $3.9M in 2011 to roughly $13.0M in 2023-2024, showing strong balance-sheet growth and resilience. Revenue has generally trended upward with variability—peaking in 2023 at $5.73M—while expenses have been broadly controlled and usually below revenue, demonstrating prudent financial management.
