What The Jmt Wilderness Conservancy does
Mission
Working to restore the watersheds, wilderness, and wildlife in the high sierra nevada following the john muir trail (est. 1915) for all life in california.
As stated on its FY2025 Form 990.
Program
The mission of The Jmt Wilderness Conservancy is to expand and restore the meadow ecosystems and riparian corridors of the central sierra nevada encompassed by the historic john muir trail, the first and oldest recreational trail in america. This high elevation terrain is covered in snow during winters and bursting with accelerated spring growth in spring/summer. Covering roughly 2.8 million acres, it is vitally important to absorb and infiltrate water, and hold it in the sierra nevada watersheds for year-round release into california's mighty rivers. It is also critical habitat for an enormous range of biodiverse species, many of them uniquely endemic to this region.studies and reports indicate that over 60% of the wet meadow alpine terrain in california has been lost in the last two hundred years. The reasons are many: voracious resource extraction, development and road construction, seasonal grazing by sheep and cattle, the decimation of native beaver species for fur trapping, and the forced (and often violent) removal of indigenous peoples who aptly managed this terrain with traditional practices.

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 2024 to 2025, from $3.1M to $5.4M (+70%).
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: 2021 3% · 2022 15% · 2023 84% · 2024 88% · 2025 90%. Grants only. Government contracts and fees sit inside program revenue.
98% of THE JMT WILDERNESS CONSERVANCY’s revenue is contributions — more reliant on donations than three-quarters of its peers (88% for the typical peer).
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 2 of the last 5 reported years ran a deficit.

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
2020 → 2023: the base broadened from 4 funders to 9 funders, grant income rose $151k → $275k.
11 of 23 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 64% 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 THE JMT WILDERNESS CONSERVANCY’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
THE JMT WILDERNESS CONSERVANCY has a broad base — no single funder exceeds 24% 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
88% 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 THE JMT WILDERNESS CONSERVANCY.
Largest funder’s share by year: 2020 79% · 2021 57% · 2022 39% · 2023 38% — 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
0% of THE JMT WILDERNESS CONSERVANCY's funders are still giving 3 years after their first grant; 48% 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
64% of THE JMT WILDERNESS CONSERVANCY'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 $696k that is directly attributable, 74% of it comes from California funders.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $1.3M arriving through sponsors registered in 9 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.
Against its field
THE JMT WILDERNESS CONSERVANCY holds deeper cash reserves than three-quarters of the 1,209 environment nonprofits its size.
