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: The Conservation Foundation has shown steady financial growth over the past decade, with revenues rising from about $1.8M in 2011 to $5.7M in 2023 and assets growing from roughly $3.9M to $13.1M (and projected to about $21.2M in 2025). Expenses have generally tracked revenues, supporting program growth while liabilities have remained modest relative to assets, indicating a strong net position and financial stability. The 2025 figures include an unusual accounting adjustment that boosts assets and alters expense and liability presentation, suggesting a one-time or reclassification event. Overall, the trend points to expanding capacity, reliable stewardship, and a healthy balance sheet.
