What Endangered Habitats League does
Mission
EHL leads the way toward a better future for southern California through the creation of secure intact native landscapes where diverse, abundant wildlife thrives, by building sustainable human communities with a high quality of life for everyone, and by protecting rural and agricultural lands from being overrun by urban sprawl.
As stated on its FY2025 Form 990.
Programs
Since 1991, the Endangered Habitats League has worked on Californias Natural Communities Conservation Planning program. EHL works with local and state advisory groups, reviews and analyzes technical documents, appears in legal proceedings, comments on and/or initiates relevant scientific studies for regional climate action and land use programs. EHL served on the Tejon Ranch Conservancy Board of Directors and on advisory committees in San Diego and Orange Counties, in the former to adopt a new North County habitat plan and in the latter to direct Measure M funding to create connectivity between NCCP regions. In San Bernardino County, in 2025, EHL made progress in its goal to preserve vital habitat for the endangered San Bernardino Kangaroo Rat and restore the upper Santa Ana River. The launch of the Greater Prado Basin Habitat Conservation Plan complements this effort. In Riverside County, EHL worked to protect a regional wildlife linkage along Temecula Creek. EHL participated in a consortium that introduces fishermen to gear systems that do not entangle whales.
$431,004 spentof which $102,000 as grants34% of program spendingEHL takes an active role in cross-border protection of habitats common to Baja California and southern California. EHL partners with Terra Peninsular and Jardin Botanico de San Quintin, Baja-based non-profits which protect habitat in Baja California through land purchases and conservation agreements with land owners, and through education programs for local residents. In 2007 and again in 2012, EHL assisted with important transactions that protected key coastal properties. In 2024, EHL continued assistance to Terra Peninsular for the stewardship of these lands, the undertaking of supporting scientific studies, and, in particular, by protecting legal rights to an essential estuary in the preserve.
$663,824 spentof which $651,749 as grants52% of program spendingIn 2006, EHL established the Endangered Habitats Conservancy for the purpose of holding land and conservation easements and managing them for their habitat values. The Conservancy has undertaken extensive habitat restoration programs along the San Diego River and elsewhere, primarily in San Diego County. In 2007, the first acquisition of 314 acres of coastal sage scrub habitat was completed, forming a southern extension of the Crestridge Ecological Preserve. Work continued on acquisition of a two-mile stretch of river basin for habitat restoration and park uses with additional purchases in 2008 and 2009 for a cumulative investment of more than 10,000,000. In 2013, EHL completed the transfer of ownership and management of these lands to EHC. In 2024, EHL continued facilitating the purchase of additional conservation property through a grant for transaction costs and operating support.

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 2020 to 2021, from $735k to $1.4M (+97%).
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.
83% of ENDANGERED HABITATS LEAGUE’s revenue is contributions — more donation-reliant than the typical peer (74% for the typical peer).
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 3 of the last 9 reported years ran a deficit.

Leadership and staff
The officers, directors, trustees and key employees listed on each return. Joined and no longer listed compare each filing with the year before, matching people by surname and first initial; a year after a gap, or a roster under three people, has no comparison.

Who funds it, year by year
2017 → 2023: the base broadened from 4 funders to 6 funders, grant income rose $123k → $455k.
5 of 12 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 37% of grant dollars received. That money is really individual donors directing a sponsor; the institutions to cultivate are the non-DAF funders.
Left out of every figure on this page: $100k from one payer (the payer shares this organization's board, largest Endangered Habitats Conservancy). These are real filings, and they are not money ENDANGERED HABITATS LEAGUE raised.
From the IRS filings of ENDANGERED HABITATS LEAGUE’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
ENDANGERED HABITATS LEAGUE has a broad base — no single funder exceeds 32% 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
55% 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 ENDANGERED HABITATS LEAGUE.
Largest funder’s share by year: 2017 37% · 2018 50% · 2019 34% · 2020 77% · 2021 68% · 2022 38% · 2023 44% — 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.
How long its funders stay
50% of ENDANGERED HABITATS LEAGUE's funders are still giving 3 years after their first grant; 83% 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
79% of ENDANGERED HABITATS LEAGUE's grant income comes from California funders.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $1.2M arriving through sponsors registered in 4 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.
