What Oc Habitats does
Mission
To provide conservation education and monitoring services for a variety of ecological habitats within Orange County California that may contain sensitive protected or listed plant or animal species.
As stated on its FY2025 Form 990-EZ.
Programs
Education & Outreach - We expanded our educational programming in 2025 by serving over 5,094 individuals in 2025. We continued to partner with Girl Scouts of Orange County,OC Coastkeeper and title 1 schools in Capistrano Garden Grove Irvine Newport-Mesa Saddleback Valley and Santa Ana Unified School Districts. We expanded our hike programs overall with Santa Ana Wilderness Club and Cancer Kinship and continued our programs with Mission Viejo to serve over 400 individuals. We were asked by the City of Newport Beach to become a contracted educator and began this process at the end of 2025. Our hikes take us all over the county where we share knowledge of habitats species indigenous history and climate change issues and impacts with attendees. We participated in thirty-seven outreach events throughout the year including Earth Day events at local community colleges Anaheims OC Green Expo OCWDs Childrens Water Festival the Panhe Gathering and Mission Viejo Environmental Fair.
$74,971 spent69% of program spendingMonitoring - We began a partnership with Xerces Society on Monarch Butterfly Overwintering Surveys in Fall of 2025. They had approached us to help and potentially take over as coordinator of Orange County in 2026. This is an exciting expansion of our work with specific species. We completed our 3rd cycle of Purple and Red Sea Urchin Population Densities surveys and prepared to renew our permit in collaboration with Get Inpsired Nancy Caruso. We did an Independence Day monitoring of the Tern Preserve to protect both CA least terns and Western snowy plovers Charadrius nivosus nivosus
$3,897 spent4% of program spendingRestoration - Received two generous grants from Henry W. & Ellen R. Warne Family Foundation and Rose Foundation to help us fund 12 months worth of restoration work within Upper Newport Bay and Santiago Creek Santa Ana. We secured a new project through HBWC Tern Preserve Cohort to help restore the tern preserve that is the only breeding ground for our endangered CA Least Tern Sterna anitillarum browni. We worked tirelessly throughout the year to remove invasive species and debris planting native plants propogating seeds and buliding new habitat in all of our sites in Huntington Beach Wetlands Conservancy salt marsh Upper Newport Bay salt marsh and riparian Huntington Beach State Park coastal dunes and Santa Ana - Santiago Creek riparian. In all of these spaces we removed close to 25,000lbs of nonnatives and debris. We had the pleasure of working with volunteers from all over Orange County and surrounding areas LA Riverside San Bernardino and San Diego counties.

The 3 programs described on its FY2025 Form 990-EZ. Program spending in total: $109,018.
The organization over time
Each line starts at 100 in 2021, so what you read is the shape rather than the size: 150 means half as much again as 2021, 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 $55k to $102k (+87%).
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.
58% of OC HABITATS’s revenue is contributions — about as donation-reliant as the typical peer (88% for the typical peer).
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 0 of the last 5 reported years ran a deficit.
Who funds it, year by year
2018 → 2023: the base broadened from 1 funder to 2 funders, grant income fell $10k → $5k.
2 of 4 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 25% 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 OC HABITATS’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
OC HABITATS leans on a few funders — its largest provides 68% 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
32% 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 OC HABITATS.
Largest funder’s share by year: 2018 100% · 2019 100% · 2020 100% · 2021 99% · 2022 79% · 2023 98% — broadly stable.
“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
OC HABITATS draws 90% of its grant income from funders outside California, across 2 states in all.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $35k arriving through sponsors registered in 2 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.
