Ada Hayden, Preserving Iowa’s Prairies

Ada Hayden August 14, 1884–August 12, 1950

Hayden is primarily associated with prairie preservation in Iowa. Within a year of earning her Ph.D., her research on the ecology of prairie plants in central Iowa was published in the American Journal of Botany (1919) and the Proceedings of the Iowa Academy of Science (1919). She issued a tentative call for prairie preservation in a short piece, “Conservation of Prairie,” published in Iowa Parks: Conservation of Iowa Historic, Scientific and Scenic Areas (1919), suggesting that a few acres of relict prairie, preferably tracts located near larger schools, be preserved in each county of the state.

Dr. Hayden is also featured this month on the Special Collections blog at the Iowa State University Library.

Education:

  • 1908 BS, Botany, Iowa State College, Ames, IA
  • 1910 MS, Botany, Washington University St. Louis, MO
  • 1911 MS, Botany, Iowa State College, Ames, IA
  • 1918 PhD, Iowa State College, Ames, IA (on “ecologic anatomy” of prairie plants)

The Iowa farm on which Ada Hayden grew up provided early inspiration for nature studies. Her parents maintained several acres of native prairie for her to play in, and later study.

While still in high school, Hayden’s interest in botany was noted by botanist Dr. Louis Pammel, who encouraged her and later became her mentor and professor during her studies at Iowa State. In 1913, she contributed a chapter (“Scattering of Weeds”) and many illustrations to his book, The Weed Flora of Iowa. She succeeded Dr. Pammel as herbarium curator after his death.

Career highlights:

After being the first woman to receive a PhD from Iowa State, Dr. Hayden joined the Botany Department there as assistant professor in 1918. She served as curator of the herbarium there, which is now named in her honor, from 1931 until her death in 1950. She taught courses in botany, ecology, algalogy, and other fields.

According to Dr. Lois Hattery Tiffany, who joined the faculty in 1950:

“In 1934, Dr. Hayden was also appointed a Research assistant professor with the Agricultural Experiment Station. Her summer work for the station involved study of the vegetation of the lakes, marshes, and border areas of the state in relation to the feeding and nesting of wild water fowl and shore birds. She managed alone such tasks as loading, transporting, and launching her boat, if wading or swimming was required to obtain specimens or to investigate the area, she accomplished the task. She was an excellent photographer and an artist, illustrating her thoughtfully written, informative reports with exceptionally good visuals.”

Dr. Hayden developed radio speeches and gave public presentations for decades to educate Iowans on the importance of prairie preservation. These talks included her hand-colored lantern slides of prairie plants. In the 1940s, she documented “more than 100 tracts of native prairie,” identifying 32 as potential preserves. She later worked with John Aikman (ESA president 1946), co-authoring a paper on managing prairie reserves shortly before her death. Dr. Aikman later cited her “important contributions” to prairie preservation. For her long dedication to documentation and conservation of Iowa prairies, the Ada Hayden Prairie Preserve in Howard County was named in her honor by the Iowa Conservation Commission.

Dr. Hayden appears in the ESA directory of 1928. According to Alton Lindsey (ESA Eminent Ecologist 1976), he saw Dr. Hayden often at ESA meetings early in his career. She was very “prominent in society affairs, active in conservation efforts,” he wrote.
