The organization over time
Each line starts at 100 in 2019, so what you read is the shape rather than the size: 150 means half as much again as 2019, 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 $199k to $386k (+94%).
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 17% · 2023 0% · 2024 0% · 2025 0%. Grants only. Government contracts and fees sit inside program revenue.

Who funds it, year by year

From the IRS filings of ZILKER BOTANICAL GARDEN CONSERVANCY NON-PROFIT CORPORATION’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
ZILKER BOTANICAL GARDEN CONSERVANCY NON-PROFIT CORPORATION has a broad base — no single funder exceeds 31% of grant income, and it takes 3 funders to reach half.
the vertical line marks half of all grant income — 3 funders to its left
86% 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 ZILKER BOTANICAL GARDEN CONSERVANCY NON-PROFIT CORPORATION.
Largest funder’s share by year: 2017 100% · 2018 100% · 2019 100% · 2020 58% · 2021 51% · 2022 69% · 2023 47% — 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.
How long its funders stay
33% of ZILKER BOTANICAL GARDEN CONSERVANCY NON-PROFIT CORPORATION's funders are still giving 3 years after their first grant; 57% 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
66% of ZILKER BOTANICAL GARDEN CONSERVANCY NON-PROFIT CORPORATION'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 $83k that is directly attributable, 52% of it comes from funders outside Texas, across 4 states.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $160k arriving through sponsors registered in 6 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.
