What California Native Plant Society does
Mission
To protect Californias native plants and their natural habitats, today and into the future, through science, education, stewardship, gardening, and advocacy
As stated on its FY2025 Form 990.
Programs
Plant ScienceCalifornia's ambitious climate, working land, and biodiversity initiatives require the best available science on the state's native plants and habitats. With the State of California's record investment in vegetation mapping, the CNPS Vegetation Program partnered to complete 5 million acres of vegetation mapping, 100 additions or updates to the Manual of California Vegetation, and monitoring and sampling of 120 federally managed public lands. Vegetation mapping on Californias Central Coast was a highlight with 2,500 new vegetation surveys, more than 10,000 existing surveys compiled. More than 190 plant alliances and 1,556 rare and sensitive plant species were mapped. During this same time, CNPS Rare Plant Program Staff vouchered 522 plants, surveyed 225 rare plants, and made 46 status additions and updates to the CNPS Rare Plant Inventory. A highlight was the teams conservation work in the Caldor Fire burn scar, where the Rare Plant team and volunteers collected 85,000 rare plant seeds for seed-banking and 19 herbarium vouchers. Together, they collected 157 data points across 58 populations of target species, thanks in part to more than 600 hours of support from CNPS…

In Education, CNPS prepared for the 2026 CNPS Conference by forming its Conference Planning Committee and beginning its work under the theme: Growing the Movement Together for Native Plants. Education Staff also designed the new Biodiversity in Urban Gardens community science project, launching in late 2025/early 2026. The team awarded 15 student research grantees over $14,000 in funding, welcomed 110 participants to sold-out plant science workshops, and, under the leadership of the CNPS Rare Plant Program, awarded 94 new Certified California Botanists. Horticulture staff began work on cooperative agreements with the California Department of Food and Agriculture to scale up native plant production and habitat for pollinators, and introduced the new, interactive Calscape Garden Planner on Calscape.org. In Public Affairs, the team continued its leadership role in the Power in Nature coalition, advocating with partners statewide for the State of Californias goal to protect 30% of…

This year, CNPS Conservation and Public Affairs staff launched a new Advocacy Corps to support its grassroots network of volunteers at key moments of decision-making. In January, CNPS staff and volunteer representatives were invited to the White House to celebrate the designations of Stttla and Chuckwalla National Monuments. The new monuments coupled with the May 2024 expansions of Berryessa Snow Mountain and San Gabriel Mountains National Monuments represented nearly 1 million newly conserved acres in California! As the new federal administration took office, CNPS and partners across the state pivoted to a statewide defense campaign to ensure Californias new national monuments and public lands stay in public hands with the highest levels of protection for native plants and habitats. CNPS also provided comment letters and initiated litigation to protect imperiled habitats and plants, including a case against the Jurupa Valley City Council to protect a…

Subject matter spans scientific, horticultural, cultural, conservation, and educational topics surrounding native plants. This year, CNPS published Part II of a special issue of its science journal, Artemisia -- Indigenous Perspectives: Native Plants and Climate Change.

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 2019 to 2020, from $7.5M to $12M (+59%).
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: 2020 3% · 2021 6%. Grants only. Government contracts and fees sit inside program revenue.
47% of California Native Plant Society’s revenue is contributions — more earned-revenue than three-quarters of its peers (88% for the typical peer).
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 2 of the last 9 reported years ran a deficit.

The officers, directors, trustees and key employees listed on each return. Joined and no longer listed compare each filing with the year before, matching people by surname and first initial; a year after a gap, or a roster under three people, has no comparison.
Who funds it, year by year
2017 → 2023: the base broadened from 18 funders to 35 funders, grant income rose $251k → $1.3M.
24 of 85 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 72% 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 California Native Plant Society’s funders (the co-funder graph). Top 30 of 85 funders by total. 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
California Native Plant Society has a broad base — no single funder exceeds 16% of grant income, and it takes 4 funders to reach half.
the vertical line marks half of all grant income — 4 funders to its left
81% 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 California Native Plant Society.
Largest funder’s share by year: 2017 31% · 2018 58% · 2019 19% · 2020 63% · 2021 32% · 2022 14% · 2023 33% — 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.
How long its funders stay
43% of California Native Plant Society's funders are still giving 3 years after their first grant; 62% 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
72% of California Native Plant Society's grant income arrives through donor-advised or pass-through sponsors, whose addresses record where the money is held rather than where the donor is. Of the $1.7M that is directly attributable, 78% of it comes from California funders.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $4.3M 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.
