Citizen Scientist: Searching For Heroes And Hope In An Age Of Extinction - Book by Mary Ellen Hannibal

Citizen Scientist: Searching For Heroes And Hope In An Age Of Extinction” (2016)

Hannibal, an award-winning writer and emerging emissary from scientists to the public, sets out to become a citizen scientist herself. In search of vanishing species, she wades into tide pools, follows hawks, and scours mountains. The data she collects will help environmental research—but her most precious discovery might be her fellow citizen scientists: a heroic cast of volunteers devoting long hours to helping scientists measure—and even slow—today’s unprecedented mass extinction.

The Spine of the Continent: The Most Ambitious Wildlife Conservation Project Ever Undertaken - Book by Mary Ellen Hannibal

The Spine of the Continent: The Most Ambitious Wildlife Conservation Project Ever Undertaken” (2012)

As climate change encroaches, animals and plants around the globe are having their habitats pulled out from under them. At the same time, human development has made islands out of even our largest nature reserves, stranding the biodiversity that lives within them. The Spine of the Continent introduces readers to the most ambitious conservation effort ever undertaken: to create linked protected areas extending from the Yukon to Mexico, the entire length of North America. This movement is the brainchild of Michael Soule, the founder of conservation biology and the peer of E.O. Wilson and Paul Ehrlich, who endorse his effort as necessary to saving nature on our continent.
