Programs
Native Plant Public Education and Publications: WNPS provides a broad array of educational services to the public through its 12 chapters and 2,750 members statewide. Our online training offers a wide variety of subjects such as native pollinators, virtual plant walks, forest fire ecology, climate change, botanical drawing and many more. Study Weekend is a member event that focuses on botanical field trips, speakers, dinners and more. Each event is sponsored by a different chapter(s), allowing this event to be held in diversified areas throughout the state. Another popular event is Botany Washington, co-sponsored with the University of Washington Herbarium at the Burke Museum (WTU). Botany Washington provides botanists, ecologists, and other professionals with access to experts and an in-depth study of selected taxonomic groups.

In two primary components; a five-week unit where students take on the role of restoration ecologists and a field experience, where the students partner with restoration experts to implement restoration components typically over two days work on public land.

WNPS has committed over twenty years of steward training to conserve, protect and sustain the biodiversity of the native flora of Washington. Participants agree to return service hours at least equivalent to their training hours in efforts such as habitat restoration in forests and woodlands, shrub-steppe, prairies, riparian and wetlands. By using stewardship training to support our YEER program above, both programs benefit each other. Continuing education is also offered to Veteran Plant Stewards.

Customers like the at-home online shopping experience, along with knowing which plants are available. These sales provide extensive education of plant materials to home gardeners and landscapers utilizing native species in their landscapes. In 2024, the chapters have improved availability by propagation (and training) of some selections to increase availability. Any remaining plants not sold online are offered during the time of plant pickup. Three chapter plant sale stores were active in 2024, providing chapter revenue to support programs, and resources in the community to support native plant gardening. Hundreds of customers have obtained plants through this program.

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 2020 to 2021, from $792k to $932k (+18%).
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: 2017 10% · 2018 13% · 2019 10% · 2020 3% · 2021 3% · 2023 3% · 2024 2%. Grants only. Government contracts and fees sit inside program revenue.
65% of WASHINGTON NATIVE PLANT SOCIETY’s revenue is contributions — about as donation-reliant as the typical peer (88% for the typical peer).

Who funds it, year by year
2017 → 2023: the base broadened from 3 funders to 7 funders, grant income rose $11k → $79k.
5 of 13 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 95% 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
WASHINGTON NATIVE PLANT SOCIETY leans on a few funders — its largest provides 61% of grant income and the top three 89%; half comes from just 1 funder.
the vertical line marks half of all grant income — 1 funder to its left
97% 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 WASHINGTON NATIVE PLANT SOCIETY.
Largest funder’s share by year: 2017 53% · 2018 100% · 2019 100% · 2020 59% · 2021 91% · 2022 38% · 2023 78% — growing more concentrated.
“Effective funders” = inverse Herfindahl index (1 / Σ shareᵢ²) — the number of equal-sized funders that would give the same concentration.

How long its funders stay
80% of WASHINGTON NATIVE PLANT SOCIETY's funders are still giving 3 years after their first grant; 54% 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
95% of WASHINGTON 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 $15k that is directly attributable, 65% of it comes from funders outside Washington, across 6 states.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $273k arriving through sponsors registered in 4 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.
