$27,268 spentof which $26,250 as grants26% of program spendingThe lyon arboretum micropropagation lab has successfully grown over 300 hawaiian plant taxa using micropropagation techniques. Micropropagation is a vital tool in plant recovery work, particularly in the case of immature seeds, rare taxa, or unhealthy plant stock. This medium-term storage method is high maintenance, but enables the growing of this irreplaceable germplasm in large numbers under disease-free, climate-controlled conditions. Fla continues to support this important program as lyon arboretum maintains and houses almost 25,000 plants, representing over 200 native plant taxa (of which more than 60% are federally listed as endangered or threatened. Research also includes developing and optimizing protocols for the maintenance of in vitro collections and acclimatization to transition them to greenhouse conditions. In the last two years, over 2,000 plants have been sent out of the lab and greenhouse for restoration purposes.

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 2023 to 2024, from $446k to $701k (+57%).

2017 → 2023: the base held at 2 funders, grant income rose $7k → $7k.
1 of 5 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 0% of grant dollars received. That money is really individual donors directing a sponsor; the institutions to cultivate are the non-DAF funders.

LYON ARBORETUM ASSOCIATION leans on a few funders — its largest provides 94% 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
95% 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 LYON ARBORETUM ASSOCIATION.
Largest funder’s share by year: 2017 85% · 2018 100% · 2019 94% · 2020 97% · 2021 99% · 2022 100% · 2023 100% — growing more concentrated.
“Effective funders” = inverse Herfindahl index (1 / Σ shareᵢ²) — the number of equal-sized funders that would give the same concentration.

In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $151 arriving through sponsors registered in 1 state 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.
