What San Francisco Bay Wildlife Society does
Mission
Nurture in the public an understanding, appreciation, and stewardship of the San Francisco Bay National Wildlife Refuge Complex, its natural and cultural history, and to conserve, preserve, and restore bay lands as essential wildlife habitat. Environmental Education supports conservation awareness and builds stewardship in local communities. Biology programs support habitat preservation and restoration. Long term partnerships with Santa Clara Valley Urban Runoff Pollution Prevention Program and local corporations provide major funding for these efforts. Efforts also support public access and conservation education.
As stated on its FY2025 Form 990.

Appointed an Executive Director who led an improved Nature Store investment at the Don Edwards San Francisco Bay National Wildlife Refuge Visitor Contact Station. The BOD approved double coverage between the outgoing Program Administrator and the incoming Executive Director, resulting in a larger-than-normal loss for the fiscal year.

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 2024 to 2025, from $250k to $215k (−14%).
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: 2018 0% · 2021 8% · 2022 0% · 2023 0% · 2024 0% · 2025 0%. Grants only. Government contracts and fees sit inside program revenue.

Who funds it, year by year
2019 → 2023: the base broadened from 1 funder to 3 funders, grant income fell $25k → $16k.
2 of 4 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 49% of grant dollars received. That money is really individual donors directing a sponsor; the institutions to cultivate are the non-DAF funders.

How concentrated its funding is
SAN FRANCISCO BAY WILDLIFE SOCIETY leans on a few funders — its largest provides 50% 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
99% 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 SAN FRANCISCO BAY WILDLIFE SOCIETY.
Largest funder’s share by year: 2019 100% · 2020 100% · 2021 100% · 2022 100% · 2023 97% — 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.
Where its funders are
SAN FRANCISCO BAY WILDLIFE SOCIETY draws 100% of its grant income from funders outside California, across 2 states in all.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $24k arriving through sponsors registered in 2 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.
