What Tenafly Nature Center Association does
Mission
Form 990, part I, line 1, description of organization mission: the association's mission is to protect almost 400 wooded acres for the purposes of conservation, education, recreation, and community engagement. We strive to protect all native species found within our preserve and teach current and future generations to do the same. Since 1961 the association has nurtured an appreciation for nature, been a leader in open space preservation and in environmental education for the community and beyond. In 2021 we continued to make quick adjustments to meet the needs of our community and school systems. As in 2020 we were able to stay open and provide supplemental education opportunities both virtually and safely outside in person. During peak hours over 14,000 visitors were able to enjoy our trails and educational exhibits and signage was added to create more passive educational opportunities throughout the year. Despite the need for restrictions and reductions due to health and safety conc
As stated on its FY2025 Form 990.

The organization over time
Each line starts at 100 in 2020, so what you read is the shape rather than the size: 150 means half as much again as 2020, 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 $441k to $644k (+46%).
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 8% · 2021 12% · 2022 25% · 2023 6% · 2024 6% · 2025 8%. Grants only. Government contracts and fees sit inside program revenue.
45% of TENAFLY NATURE CENTER ASSOCIATION’s revenue is contributions — more earned-revenue than three-quarters of its peers (88% for the typical peer).

Who funds it, year by year
2017 → 2023: the base broadened from 1 funder to 9 funders, grant income rose $3k → $19k.
7 of 27 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 52% 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 TENAFLY NATURE CENTER ASSOCIATION’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
TENAFLY NATURE CENTER ASSOCIATION has a broad base — no single funder exceeds 20% of grant income, and it takes 5 funders to reach half.
the vertical line marks half of all grant income — 5 funders to its left
60% 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 TENAFLY NATURE CENTER ASSOCIATION.
Largest funder’s share by year: 2017 100% · 2018 71% · 2019 83% · 2020 25% · 2021 57% · 2022 68% · 2023 40% — 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
38% of TENAFLY NATURE CENTER ASSOCIATION's funders are still giving 3 years after their first grant; 44% 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
52% of TENAFLY NATURE CENTER ASSOCIATION'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 $90k that is directly attributable, 61% of it comes from New Jersey funders.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $96k arriving through sponsors registered in 7 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.
