What Island Conservation does
Mission
Prevent extinctions by removing invasive species from islands. By rewilding islands, we restore and protect wildlife, communities, and oceans. Restoring islands by removing invasive species has repeatedly proven to be a high impact conservation action.
As stated on its FY2024 Form 990.
Programs
Conservation operations: islands are biodiversity hotspots and hope spots for the planet. They're special places where conservation interventions make an outsized impact for nature, oceans, and people. Islands are on the front lines of three major threats: climate change, extinction crisis, and failing ocean health--but they are also resilient. By bringing back biodiversity, Island Conservation restores the vital nutrient flows that nourish both land and sea, a nature-based solution that prevents extinctions, improves human livelihoods, and boosts climate resilience. Island Conservation supports local island communities' vision of a world filled with vibrant, thriving island ecosystems. In so doing, we foster sustainable development, climate resilience, and healthy island-ocean ecosystems across the globe.

We pair land-based methods with marine monitoring to paint a holistic picture of interconnected ecosystems, and we continue to monitor these project sites for years after the interventions are implemented. Scientifically documenting the response of island species and ecosystems also enables us to adjust and improve island restoration strategies and tools. We aim to increase the scope, scale, and pace of island restoration projects globally.

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 2019 to 2020, from $4.4M to $9.3M (+111%).
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 5% · 2021 8% · 2022 6% · 2023 17% · 2024 25%. Grants only. Government contracts and fees sit inside program revenue.
85% of ISLAND CONSERVATION’s revenue is contributions — about as donation-reliant as the typical peer (87% for the typical peer).
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 5 of the last 8 reported years ran a deficit.

Who funds it, year by year
2017 → 2023: the base broadened from 15 funders to 34 funders, grant income rose $1.5M → $4.1M.
15 of 77 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 14% 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 ISLAND CONSERVATION’s funders (the co-funder graph). Top 30 of 77 funders by total. 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
ISLAND CONSERVATION has a broad base — no single funder exceeds 34% 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
46% 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 ISLAND CONSERVATION.
Largest funder’s share by year: 2017 42% · 2018 42% · 2019 26% · 2020 27% · 2021 34% · 2022 60% · 2023 26% — 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
50% of ISLAND CONSERVATION's funders are still giving 3 years after their first grant; 60% 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 ISLAND CONSERVATION's grant income comes from California funders.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $4.5M arriving through sponsors registered in 11 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.
