Stewardship work develops and implements science-based approaches to taking care of lands and waters.

In addition to stewarding the ~5,000 acres we hold, we take a regional approach working in partnership with other organizations, indigenous groups, land managers, public and private landowners on strategies to improve habitat connectivity, increase climate resilience, improve biodiversity, while building a workforce of trained stewards in the north san francisco bay region.

The organization over time
Each line starts at 100 in 2017, so what you read is the shape rather than the size: 150 means half as much again as 2017, 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 $48M to $42M (−13%).
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: 2021 6% · 2024 18% · 2025 10%. Grants only. Government contracts and fees sit inside program revenue.

From the IRS filings of AUDUBON CANYON RANCH INC’s funders (the co-funder graph). Top 30 of 65 funders by total. Association, not causation.

the vertical line marks half of all grant income — 3 funders to its left
36% of the income these shares are computed over arrives through pass-through sponsors or from payers whose filings do not say what kind of payment it is. Concentration is still measured over all of it, because the money is real; what it does not support is a claim about how many institutions have chosen to fund AUDUBON CANYON RANCH INC.
Largest funder’s share by year: 2017 27% · 2018 22% · 2019 58% · 2020 47% · 2021 38% · 2022 36% · 2023 53% — growing more concentrated.
“Effective funders” = inverse Herfindahl index (1 / Σ shareᵢ²) — the number of equal-sized funders that would give the same concentration. 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.

Share of funders still giving k years after their first recorded grant, pooled across every acquisition cohort. A funder counts as retained in a year only if it made a grant that year.

In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $1.6M arriving through sponsors registered in 12 states 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.
