Plagues and earthly paradises
former park ranger Michael J. Yochim takes us on a tour of some of this country’s most iconic national parks, from Washington’s Olympic, to Arizona’s Grand Canyon, Montana’s Glacier and California’s Sequoia, Kings Canyon and Yosemite. Along the way, he addresses the drastic impacts of climate change on their ecosystems, while regaling us with engrossing facts about the complex life they harbor, noting, for example, that a certain kind of lichen is found only on 400-year-old trees in Olympic’s rainforests.
