Through words and photographs, environmental scientist Gretchen C. Daily and photographer Charles J. Katz describe how one relict tree?the magnificent Ceiba pentandra in Sabalito, Costa Rica?carries physical and spiritual importance. The people in the town of Sabalito call the tree la ceiba, a term said to be derived from a Taíno word referring to a type of wood used for making canoes in the West Indies. Ceiba evokes times and places where people hollowed out the great cylindrical trunks and glided along languid rivers winding through lush tropical forest. Today the tree is known by different names in regions ranging from southern Mexico and the Caribbean to the southern edge of the Amazon Basin and in western Africa. The ceiba has survived what is probably the highest rate of tropical deforestation in the world. It is a legendary and vital tree in centuries-old forests in places like Costa Rica that were once almost completely forested (98 percent in the mid-twentieth century) and decades later have suffered devastating deforestation (34 percent by 1980). One Tree grew out of a conversation between photographer Chuck Katz and acclaimed ecologist Gretchen Daily about the relict tree?a single tree that remains standing in a pasture, for example, after the forest has been cleared from the land, and takes on iconic importance for the animals, plants, and people in the ecosystem.
