Programs
See detail in attachment Achievements.pdf Provide Environmental Education - As a leader in the community, we will raise awareness of important environmental issues in the county and region and promote environmental ethic of Calvert County residents and visitors. We will do this both as a partner to the county nature parks and as a stand-alone organization. The Society is an advocate for public access to natural lands and waterways in the county. The Society supports the activities led by Calvert County Department of Parks & Recreation Natural Resources Division. Our nature parks, and the programs that are provided through them, are second to none. We encourage residents and visitors to the county to enjoy these parks and activities to the fullest. Our goal is to have a series of programs that inform and connect the community to its natural heritage and create a passion for the environment.

Calvert Nature Society is positioned to be an advocate for public access to natural lands and waterways in the county. Our goal is to support and enhance these efforts in general throughout the county. Through our Land program, the Society will help protect natural spaces and local streams from stressors from development, climate change and invasive species. Because we will not, in most cases, be the owner or manager of these properties, we will work with partners to support land conservation and work to influence outcomes and set the stage for successful land protection initiatives.

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 2024 to 2025, from $1.7M to $1.8M (+4%).
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 30% · 2018 20% · 2019 1%. Grants only. Government contracts and fees sit inside program revenue.
23% of Calvert Nature Society Inc’s revenue is contributions — more earned-revenue than three-quarters of its peers (92% for the typical peer).

Who funds it, year by year
2020 → 2023: the base held at 1 funder, grant income fell $170 → $50.
1 of 1 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 100% 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 Calvert Nature Society Inc’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.
Where its funders are
100% of Calvert Nature Society Inc'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. Too little is directly attributable to place on a map.
Funder states come from each funder’s own filing. $611 arriving through sponsors registered in 1 state 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.
