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.
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.
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 5 of the last 9 reported years ran a deficit.

Who funds it, year by year
2020 → 2023: the base broadened from 2 funders to 5 funders, grant income rose $626 → $46k.
4 of 9 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 40% of grant dollars received. That money is really individual donors directing a sponsor; the institutions to cultivate are the non-DAF funders.
From the IRS filings of REDWOOD TRAILS ALLIANCE’s funders (the co-funder graph). Association, not causation. 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.
How concentrated its funding is
REDWOOD TRAILS ALLIANCE has a broad base — no single funder exceeds 23% of grant income, and it takes 3 funders to reach half.
the vertical line marks half of all grant income — 3 funders to its left
67% 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 REDWOOD TRAILS ALLIANCE.
Largest funder’s share by year: 2020 80% · 2021 84% · 2022 54% · 2023 54% — diversifying over time.
“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.
How long its funders stay
75% of REDWOOD TRAILS ALLIANCE's funders are still giving 1 year after their first grant; 33% give in more than one year at all.
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. Measured to FY2023, the last fiscal year that has finished arriving — a funder cannot be counted as lapsed in a year most filers have not reached.
Where its funders are
100% of REDWOOD TRAILS ALLIANCE's grant income comes from California funders.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $52k arriving through sponsors registered in 4 statesis 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.
