The episode mentions Marjory Stoneman Douglas, who became an important public voice in support of the Everglades in the face of attitudes like those of a respected zoologist of the day, who argued that "a swamp is a swamp." However, the series is particularly drawn to the figure of George Melendez Wright, originally a naturalist at Yosemite who became in 1933 head of the National Parks Service's newly established wildlife division. Wright took a research party over the Everglades in the Goodyear blimp, and the quantity and diversity of wildlife he observed helped convert him to a fervent champion of establishing this unique swamp as a park.

Great backlist titles on the natural history of the Everglades include naturalist Ted Levin's LIQUID LAND and Susan Cerulean's vivid account of a search for swallow-tailed kites, TRACKING DESIRE. Finally, for a true insider account of the wilderness Everglades, before development and drainage, try Rob Storter's charming, illustrated CRACKERS IN THE GLADE.
