What Plantamnesty does
Mission
PlantAmnesty's mission is to provide education, resources and advocacy to prevent mal-pruning and preserve urban greenspace.For nearly forty years, PlantAmnesty has been educating the general public and horticultural professionals on industry standard pruning of trees and shrubs to maintain the health of the urban landscape. The care and treatment of our urban forest has taken on high priority in the struggle against climate change as we rely on the carbon offset from older trees and plantings to clean our air and reduce temperatures. PlantAmnestys dynamic and professional classes, workshops and public events are cutting edge in this fight. We partner with the University of Washington Center for Urban Horticulture, WWU Master Gardeners, Bellevue Botanical Gardens, Edmonds College Horticultural Program and many local garden clubs and professional arborists to bring the message of care to the community at large. From individual homeowners to amateur orchardists to city parks personnel to

Programs
Creating Public Awareness of the Issues: PlantAmnesty uses any and all avenues to bring awareness of proper plant pruning to the general public. Boothing events provide PlantAmnesty with the one-on-one opportunity to reach new demographics in a festive setting and included The NW Flower and Garden Show five-day event along with Lake Forest Parke Green Fair, Redmonds Green Elephant Plant Swap, Alzheimers Caregiver Summit at Emerald Downs, Rainier Farm Fest at Rainier Beach Urban Farm & Wetlands, NEST Senior Fair at Magnuson Park, Bellevue Botanic Gardens Plant Sale, Ballard P-Patch Art Walk, and Shark Garden. The distribution of free literature (in English and Spanish) and hands on demonstrations help PA deliver its message. For the second year in a row, PA teamed up with the King County Master Gardeners program to teach pruning to Master Gardeners with a hands-on workshop at Highline Botanical Gardens in SeaTac. Public outreach included Arbor Day which saw teams of PlantAmnestys Referral Service professional arborists voluntarily working on trees and plantings on the Ryther campus for children with behavior challenges. PlantAmnestys Speakers Bureau provided expert Speakers to…
$23,293 spent28% of program spendingEducation/Solutions to the Problem: Education and outreach is a key component of PlantAmnestys mission and its premiere program is the Master Pruner certification series. Each year PA provides professional ISA certified classes and workshops for both those working in the field and individual gardeners/homeowners. The year-long program consisting of fourteen classes and three workshops required to earn Master Pruner certification are taught by professional horticulturists. In 2025 PA returned to the live, in-person classes with all the inherent advantages of group interaction. Class topics include fruit tree pruning from apples to cherries, all levels of tree care from 80 Douglas Firs to 8 Dogwoods, pruning for the health of major shrubs such as Rhododendrons and Azaleas, renovation of cane growing roses and Forsythia and so much more. The program is repeated in summer and winter in a six-week/twelve classes condensed course for professionals through PlantAmnestys partnership with the University of Washingtons Center for Urban Horticulture. The three required hands-on workshops are conducted in the field with professional instructors and volunteers working alongside students on…
$51,245 spent62% of program spendingEngender Respect for Plants and their Diversity: This aspect of the PA may seem superfluous but is actually essential in changing the publics viewpoint of how plants and trees impact our environment and aid against climate change. As long as humans view trees and plants as incidental, the ecosystem is at risk. PAs work in this area includes: The Cass Turnbull Garden is a long-term program of PA begun in 2018 after the death of founder Cass Turnbull. The property was donated by the philanthropic Bullitt Family to the City of Seattle and PA has worked with Seattle Parks and Recreation to continue to build an urban oasis of ADA accessible paths, public art and overlooks with more than 300 donated plantings. 350 volunteers have donated over 17,000 hours of their time and expertise to the creation of the garden. For 2025 under conditions dictated by Seattle Parks and Recreation, volunteerscontributed 765 hours weeding, raking, mulching, watering and pruning regularly in the garden and selected areas of the 1.75-acre property. A recent new agreement with Seattle Parks and Recreation granted the CTG permission to design and develop an additional corner of the property with space for…

The organization over time
Each line starts at 100 in 2021, so what you read is the shape rather than the size: 150 means half as much again as 2021, 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 2023 to 2024, from $435k to $263k (−40%).
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 5%. Grants only. Government contracts and fees sit inside program revenue.
64% of PLANTAMNESTY’s revenue is contributions — about as donation-reliant as the typical peer (73% for the typical peer).
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 3 of the last 5 reported years ran a deficit.

Who funds it, year by year
2020 → 2023: the base narrowed from 3 funders to 2 funders, grant income fell $21k → $7k.
4 of 12 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 58% 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 PLANTAMNESTY’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
PLANTAMNESTY leans on a few funders — its largest provides 41% of grant income and the top three 69%; half comes from just 2 funders.
the vertical line marks half of all grant income — 2 funders to its left
79% 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 PLANTAMNESTY.
Largest funder’s share by year: 2020 100% · 2021 54% · 2022 56% · 2023 99% — broadly stable.
“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
17% of PLANTAMNESTY's funders are still giving 2 years after their first grant; 25% 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
58% of PLANTAMNESTY'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 $49k that is directly attributable, 69% of it comes from funders outside Washington, across 5 states.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $68k arriving through sponsors registered in 3 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.
Against its field
PLANTAMNESTY's revenue fell 60% between 2021 and 2025.
