What Wolf Hollow Wildlife Rehabilitation Centre does
Mission
To promote the well-being of wildlife and their habitats through rehabilitation of injured and orphaned wildlife, public education and non-invasive research.
As stated on its FY2024 Form 990.
Programs
Wolf Hollow Wildlife Rehabilitation Center took in 298 wild animals during the year representing 91 species. Animals form 17 locations including multiple islands and the mainland in the Pacific Northwest. Ninety Seven, 97, animals were released with an uncorrected rate of 35.4%, a return to rehabilitation standards. Numbers were lower due to the center taking an intake pause October-December due to staffing changes at the center. In 2024, Wolf Hollow Wildlife Rehabilitation Center treated 4 Harbor Seals and released 3, one was humanly euthanized as it was determined it would not survive its injuries. All Harbor Seal Pups were from the San Juan County Marine Mammal Stranding network. The center has been receiving less pups since SR3 opened in Seattle in 2021. The rabbit population had a virus this year, but as the rabbits on San Juan Island are ferial domestics, none came in for care.
$314,248 spentof which $1,494 as grants$284,342 earned by the program73% of program spendingEducational activities were back in full strength in 2024. We participated in 83 events and engaged with 2,869 people. Some activities included weekly talks at national, state, and county parks, the local summer camps, and several special events. The largest event was four days at the San Juan County Fair where we interacted with 598 attendees. The majority of the educational activities take place in the summer months, but due to the centers pause, there were no educational events October-December. The Summer Internship program where interns come for two months of hands-on training was back to full strength. Eight rehabilitation interns, one educational intern were in attendance over the busy summer months. Madrona, our last educational ambassador, retired from service in March 2024. She was showing signs of arthritis which caused her pain. It was time to let her relax and enjoy her golden years.

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 $417k to $703k (+68%).
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: 2017 2% · 2018 11% · 2019 17% · 2020 12% · 2021 9% · 2022 5% · 2023 8% · 2024 0%. Grants only. Government contracts and fees sit inside program revenue.
97% of WOLF HOLLOW WILDLIFE REHABILITATION CENTRE’s revenue is contributions — more donation-reliant than the typical peer (86% for the typical peer).

Who funds it, year by year
2017 → 2023: the base broadened from 5 funders to 10 funders, grant income rose $31k → $92k.
10 of 21 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 75% 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 WOLF HOLLOW WILDLIFE REHABILITATION CENTRE’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
WOLF HOLLOW WILDLIFE REHABILITATION CENTRE has a broad base — no single funder exceeds 19% 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
75% 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 WOLF HOLLOW WILDLIFE REHABILITATION CENTRE.
Largest funder’s share by year: 2017 38% · 2018 29% · 2019 39% · 2020 31% · 2021 23% · 2022 32% · 2023 28% — 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
69% of WOLF HOLLOW WILDLIFE REHABILITATION CENTRE's funders are still giving 3 years after their first grant; 57% 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
75% of WOLF HOLLOW WILDLIFE REHABILITATION CENTRE'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 $166k that is directly attributable, 52% of it comes from funders outside Washington, across 5 states.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $499k arriving through sponsors registered in 7 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.
