Mission: Fragile Inheritance promotes and supports the long term study of species and habitats, human & environmental effects on them, and the conservation of biodiversity, based on the lifetime work of Fred Schueler & Aleta Karstad.

"These examples continue to reinforce to me the value of good inventory and the valuable contribution of many of the contributors on the NatureList."
