What Springs Stewardship Institute does
Mission
We promote and improve scientific understanding and stewardship of springs ecosystems and the riparian systems they support. We pursue this mission through research, sharing information, stewardship, and collaboration. We work closely with individuals and organizations with similar goals to plan and conduct springs research and disseminate the results. We provide information, trainings, advisement, tools, and expertise, both directly and electronically, to interested springs stewards. With the goal of reaching a broad and inclusive audience, we conduct outreach and education by publishing our findings and providing lectures and other presentations. We provide advisement and assistance to agencies conducting restoration or other management activities that promote the ecological care of springs. These strategies are designed to advance sustainable ecological stewardship of springs ecosystems for the benefit of nature and humanity.
As stated on its FY2025 Form 990.
Programs
Springs Ecosystem Inventory and Assessment Consulting - The primary focus of this program is to inventory and assess spring ecosystems and provide recommendations to land managers to improve stewardship. Land managers include private landowners, federal and state agencies, tribes, and other nonprofit organizations. We submit project-level reports summarizing data collection and findings and provide geodatabases to partners while also hosting data on Springs Online (https://springsdata.org).This work also includes supporting and, in some cases, implementing restoration and protection actions informed by these assessments, such as fencing, flow restoration, and habitat improvement, as well as monitoring to evaluate effectiveness. More broadly, this program integrates hydrology, biology, and geomorphology to inform management and conservation at both site and regional scales.

Data include flow, water chemistry, vegetation, invertebrates, vertebrates, geomorphology, georeferencing, and imagery.The platform supports data integration, analysis, and reporting, with export options to Excel, Word, and GIS formats. It also includes spatial tools for mapping and visualization. Springs Online provides free access to a broad user base, including students, researchers, land managers, tribes, and nonprofit organizations, and serves as shared infrastructure for understanding and managing spring ecosystems.

The organization over time
Each line starts at 100 in 2021, so what you read is the shape rather than the size: 150 means half as much again as 2021, 50 means half. The number beside each label in the key is where it ended. The shaded band is where the middle 50% of its peers' revenue would sit, given their growth.
Balance sheet
Total assets and total liabilities at each year end, in dollars. The largest one-year move in total assets was 2021 to 2022, from $18k to $114k (+544%).
How it's funded, over time
Each bar is one year's revenue split into where it came from, and every bar is the same height — these are shares, not amounts, so a year that raised twice as much looks the same size. Hover a bar for the split.
Government-grant reliance: 2022 0% · 2025 50%. Grants only. Government contracts and fees sit inside program revenue.
83% of SPRINGS STEWARDSHIP INSTITUTE’s revenue is contributions — more donation-reliant than the typical peer (79% for the typical peer).
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 0 of the last 5 reported years ran a deficit.

1 of 2 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 1% of grant dollars received. That money is really individual donors directing a sponsor; the institutions to cultivate are the non-DAF funders.

SPRINGS STEWARDSHIP INSTITUTE leans on a few funders — its largest provides 99% of grant income and the top three 100%; half comes from just 1 funder.
the vertical line marks half of all grant income — 1 funder to its left

“Effective funders” = inverse Herfindahl index (1 / Σ shareᵢ²) — the number of equal-sized funders that would give the same concentration.

Where its funders are
SPRINGS STEWARDSHIP INSTITUTE draws 100% of its grant income from funders outside Arizona, across 1 state in all.
Funder states come from each funder’s own filing. $276 arriving through sponsors registered in 1 state is excluded from the map and the split above: a sponsor holds money on a donor’s behalf, so its registered address would place those dollars somewhere no donor need ever have been. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
