What Trout Lake Nature Center Inc does
Mission
The mission emphasizes environmental education for children and adults. The children's education, largely for elementary schools is designed in conjunction with florida state standards and administered by volunteers and staff. The adult programs involve staff and non-staff experts conducting activities on site and also include visits to other locations.
As stated on its FY2025 Form 990.
Programs
The mission of the trout lake nature center is to connect people with nature through education and conservation. Programming is provided for students, homeschoolers and youth organizations. School programs include field trips with activities that are correlated to florida's science education standards and vary by grade level. In-school presentations are provided per grade level on a class by class basis. Concepts such as food webs, adaptations, water quality, vertebrates and invertebrates, classification of species, weather, biodiversity and more are taught through interactive lessons. In addition to teaching science concepts, students and youth make valuable connections to nature and our natural resources.

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 2024 to 2025, from $2.4M to $3.4M (+45%).
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.

Who funds it, year by year
2017 → 2023: the base broadened from 2 funders to 4 funders, grant income rose $29k → $45k.
7 of 17 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 29% of grant dollars received. That money is really individual donors directing a sponsor; the institutions to cultivate are the non-DAF funders.

How concentrated its funding is
TROUT LAKE NATURE CENTER INC has a broad base — no single funder exceeds 22% of grant income, and it takes 4 funders to reach half.
the vertical line marks half of all grant income — 4 funders to its left
35% 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 TROUT LAKE NATURE CENTER INC.
Largest funder’s share by year: 2017 88% · 2018 39% · 2019 30% · 2020 29% · 2021 36% · 2022 45% · 2023 44% — 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
36% of TROUT LAKE NATURE CENTER INC's funders are still giving 3 years after their first grant; 59% 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
95% of TROUT LAKE NATURE CENTER INC's grant income comes from Florida funders.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $137k 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.
