In 1892, Wood River Valley pioneer and botanist Eliza Avery Brodhead collected an uncommon spring-blooming primrose near Ketchum and Bayhorse, but in the intervening 134 years, those populations have gone unnoticed or have perhaps even disappeared. This talk follows a biogeographer’s slightly obsessive search for Mrs. Brodhead’s enigmatic primroses and shows how local knowledge, citizen science, and modern mapping technologies can help document and protect overlooked plant populations in central Idaho.

Presented in partnership with the Sawtooth Interpretive & Historical Association (SIHA), kicking off their 2026 Summer Series.
