Iowa Lakeside Laboratory (Herbarium code ILH) was founded in 1909 for “the study of nature in nature.” It is owned by the State of Iowa, operated through the Board of Regents, and is a member of the Organization of Field Stations. The Dark Data Project began as an effort to bring the thousands of early 20th century natural history specimens sitting in storage “to light”. Natural history collections, because they document life in earlier times, are important tools for investigating understanding the broad questions of climate change, evolution, genetics, conservation, resource management, and education. By digitizing, transcribing, and releasing this data set to researchers around the world, the legions of ecologists that have worked at Iowa Lakeside Laboratory will continue to contribute to science.
The Iowa Lakeside Laboratory natural history specimens are included in the following collections.

Non-vascular plants
Henry S. Conard (1874 – 1971) established “The Moss Clinic” in 1950. This annual workshop hosted scholars from across the US and Canada to study mosses and solve taxonomic problems (Welch and LeBlanc 1972). At the time Dr. Conard was a professor at Grinnell College and a taxonomic expert in the mosses and water lilies. The State University of Iowa (University of Iowa) provided funding for the moss clinic. There were many notable alumni of the clinic, including many women, Dr. Eula Whitehouse, Dr. Winona Welch, Dr. Elva Lawton, and Rhoda Thompson.
