CORA HARTSHORN ARBORETUM & BIRD SANCTUARY

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.

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 23% · 2018 18% · 2019 14% · 2020 17% · 2021 34% · 2022 15% · 2023 14% · 2024 11%. Grants only. Government contracts and fees sit inside program revenue.

Surplus & reserves

Operating surplus or deficit each year, and months of liquidity in hand. 6 of the last 8 reported years ran a deficit.

Who funds it, year by year

2017 → 2023: the base broadened from 2 funders to 4 funders, grant income fell $52k → $7k.

3 of 9 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 76% 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 CORA HARTSHORN ARBORETUM & BIRD SANCTUARY’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

CORA HARTSHORN ARBORETUM & BIRD SANCTUARY leans on a few funders — its largest provides 69% of grant income and the top three 89%; half comes from just 1 funder.

76% 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 CORA HARTSHORN ARBORETUM & BIRD SANCTUARY.

Largest funder’s share by year: 2017 100% · 2019 100% · 2020 99% · 2021 100% · 2022 100% · 2023 73% — 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

25% of CORA HARTSHORN ARBORETUM & BIRD SANCTUARY's funders are still giving 3 years after their first grant; 33% 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

76% of CORA HARTSHORN ARBORETUM & BIRD SANCTUARY'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 $18k that is directly attributable, 69% of it comes from New Jersey funders.

Funder states come from each funder’s own filing. $57k arriving through sponsors registered in 3 statesis 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.
