Mission
The Indiana Karst Conservancy is a non-profit organization dedicated to the conservation and preservation of caves and karst features in Indiana and other areas of the world. The Conservancy encourages research and promotes education related to karst and its proper, environmentally compatible use.
Program accomplishments
- Educational Services - The IKC has many volunteers who provide educational services to school groups, conservation groups, youth groups (e.g., Scout troops, developers, government agencies, and the general public who live in karst areas). In 2025 volunteers organized or presented at a number of events. In addition to our direct outreach, we have participated in authoring newspaper articles, have educational materials on our website, and have provided educational opportunities through our property holdings. The IKC's seven properties provide visitors with various opportunities including "wild" caving experiences, interpretive hiking on trails, and easy access to a large karst spring/resurgence. We also publish a quarterly newsletter to promote karst education opportunities and report on accomplishments. This newsletter is distributed for free to our members, supporters, and regional/national organizations and government agencies. It is also available (along with all back issues) on our public website.Expenses $4,543

In 2025, we continued to expended resources (funds and volunteer labor) at our various preserves, including trail maintenance, tree planting, invasive plant control, and the restoration and maintenance of our preserves. This year we also made capital investments in a brush mower and other stewardship tools, partially funded by a wildlife habitat grant.Expenses $11,169 · revenue $10,000
