Program
Through the kosmos program we designed interpretive signs for the lafitte nature trail, we started rebuilding the lafitte nature trail that was destroyed during hurricane ida. We also started a climate workforce development training program for inner-city at-risk adults to train them work in wetland restoration. We planted 800 cypress seedlings, hosted 8 interns to work on the boardwalk, and hosted 4 wetland education workshops. We also started a feasibility study to plant 130,000+ acres with cypress trees for carbon credits.

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 2021 to 2022, from $283k to $465k (+65%).
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.
100% of TIERRA INTERNATIONAL FOUNDATION’s revenue is contributions — more reliant on donations than three-quarters of its peers (92% for the typical peer).
Surplus & reserves

Who funds it, year by year
2020 → 2022: the base narrowed from 3 funders to 1 funder, grant income fell $287k → $97k.
1 of 3 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 51% 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 TIERRA INTERNATIONAL FOUNDATION’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
TIERRA INTERNATIONAL FOUNDATION leans on a few funders — its largest provides 51% 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
78% 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 TIERRA INTERNATIONAL FOUNDATION.
Largest funder’s share by year: 2020 38% · 2021 100% · 2022 100% — growing more concentrated.
“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.
Where its funders are
51% of TIERRA INTERNATIONAL FOUNDATION'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 $196k that is directly attributable, 100% of it comes from funders outside Colorado, across 2 states.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $205k 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.
