Watch for the eyes of alligators as they emerge from the murky waters. Listen to the songs of frogs as they call their mates. Flit from cattail to cattail with graceful dragonflies. Check out the following books, DVD and specimens in the Naturalist Center, as well as other resources on wetlands and other freshwater sources. Then see live animals from wetlands in the southeastern United States in our Swamp exhibit.

Book and Media Reviews

Wilson, Sam and Moritz, Tom (eds.). The Sierra Club Wetlands Reader: A Literary Companion. San Francisco: Sierra Club Books, 1996. Nat. Ctr. QH76 .S58 1996

This is a great bedside book with a wealth of essays and writings to dip into. The Wetlands Reader is divided into two sections. The first, ‘Impressions’, contains a collection of readings by well-known figures: from Mark Twain to Zane Grey via Frederick Law Olmsted and Henry David Thoreau. Many of these selections are not specifically about wetlands; often the wetlands are part of the context of a story or a ‘character’ in their own right.

The second section of the Reader, entitled ‘Impacts and Compensations’, is “concerned with America’s cultural about-face regarding wetlands, from historical policies that rewarded destruction to today’s attempts at preservation and restoration”. It includes excerpts from significant government documents, as well as literary, legal and social commentary, many of them from the Bay Area.

The readings are interesting individually, and as a collection give a many faceted picture of one of our most fascinating ecological communities. There is a useful glossary and extensive bibliography for further reading.

Hoose, Phillip. The Race to Save the Lord God Bird. New York: Farrar, Staus and Giroux, 2004. Nat. Ctr. Juv. QL696.P56 H66 2004

Combining history, biology, adventure, and mystery, Hoose relates the tale of the Ivory-billed Woodpecker from it abundance in southern U.S. forests to its presumed extinction. Known as the “Lord God Bird” since when seen flying overhead that is all one can shout out in amazement, this majestic bird and the fight to save it helped shaped the conservation movement in the U.S., influencing the development of important conservation groups, such as the Audubon Society and the Nature Conservancy. Archival photos interspersed throughout the text help bring the history to life, and a glossary clarifies some of the terms used for younger readers. Meticulously researched and engagingly written, this important book helps readers see the interconnections between politics, economics and the environment, while impelling young conservationists to act given the urgency that still exists in conserving wildlife and its habitat in the U.S. Recommended for ages 12 to adult.

The Wetlands.[VHS]. Pittsburgh PA: Metropolitan Pittsburgh Public Broadcasting Inc., 1988. Nat. Ctr. Media QH76 .W47 1988

The Wetlands is part of WQED’s Conserving America series. The film examines the effects, both positive and negative, that people have had on wetlands across the U. S. from Florida to the San Francisco Bay Area. For some years the balance between economic development and conservation has been heavily in favor of development and these richly populated areas have suffered, in much the same way and for the same reasons as rainforests have. The Wetlands shows what a diverse array of people across the country has done, and is doing, to stop and reverse this decline. This includes farmers, a business coalition, naturalists, writers and those who make a living from the swamps, like Alligator Annie – a tour guide in the Everglades. There is an extended interview with Marjory Stoneham Douglas who wrote the classic River of Grass(available in the Academy’s Main Library) and, 40 years later, is still campaigning to save the Everglades. Although the video is somewhat dated, its central message remains true: it is down to all of us to protect our swamps and wetlands and their rich diversity of life.

Featured Creatures

American Bittern

Spotting this bird can be a tricky feat. Once detected, the American bittern (Botaurus lentiginosus) turns toward the threat, stretches its long neck and pointy bill upward, stands still, and sways ever so slightly. Its mottled brown plumage with vertical front stripes blends in amongst the tall, swaying grasses, reeds, and sedges of the freshwater and brackish marshes where it lives. So innate is this defensive behavior that the bird will even strike this pose when it is out in the open, away from its protective surroundings.

Western Pond Turtle

The only turtle native to California, western pond turtles (Actinemys marmorata) are found, as one would expect, in ponds, as well as other freshwater habitats. Their numbers are in serious decline throughout more than three-quarters of their range because of habitat loss and predation. If you spy a turtle basking on a log or mudbank, chances unfortunately are that it is a nonnative one. Hard-shelled western pond turtles and nonnative sliders and painted turtles all have similarly shaped, blunt-nosed heads. However, western pond turtles’ heads are lighter with black speckles, while sliders and painted turtles’ are darker with colored stripes or swirls.
