Using a nationwide survey of Forest Service employees, this article compares the land ethic of foresters with that of other natural resource professionals and examines the relationship between one's land ethic and preferred forest policy options. Professional foresters embrace a more utilitarian land ethic than that expressed by biologists and other natural resource scientists in the agency. Because the number of foresters, engineers, and range managers in the Forest Service is declining while the ranks of natural resources scientists are growing, changes in the short-term management of national forest units may be forthcoming.

Leopold’s teaching is based on the belief that “the land is one organism.” Will an ecosystem collapse if a single species is removed, as would an organism without a single organ? What would happen if all native plants and the animals that depend on them were replaced by a single introduced species? The answer: a sustainable wheat field, without which Leopold would not be able to create his ethic, nor we conduct this discourse.

Reevaluating Aldo Leopold’s land ethic is timely, but Boris Zeide’s critique of it is both biased and logically flawed. The real target of Zeide’ essay is ecosystem management. The real sciences in which the land ethic is grounded are evolutionary biology, community ecology, and ecosystem ecology, not the outmoded Clementsian superorganism paradigm in ecology. Although Zeide believes in a strictly zero-sum world, Aldo Leopold had faith that we could achieve win-win solutions: log our forest and maintain their health and integrity; prosper economically and protect out ecological heritage.

Ecological restoration has been attacked as a morally repugnant attempt to take nature. “Postmodernism,” or poststructuralist epistemology, has been similarly attacked for its rejection of belief in “real nature.” The essentialism of these attacks is inconsistent with the empirical basis of science and value. The science of complexity theory is supportive of poststructuralism and ecological restoration, and an understanding of poststructuralism in facts enables us to defend ecological restoration as a joyful and creative act.

Genetic diversity in forest trees is best conserved in native populations. However, natural populations are threatened by many factors, eliminating valuable but often cryptic genetic resources. Gene banks (seed banks, plantations, or clonal archives) provide a prudent backup for breeders and ecological restorers should native populations be lost. Ottawa Valley white spruce, Guadalupe Island pine, and Torrey pine are examples of the value of gene banks in the conservation of forest genetic resources.

This study combines the spatial simulation of forest development on a large landscape, including wildfire occurrence and effects, with the search for management actions that achieve multiple goals. The approach was applied to the Eldorado National Forest. Resulting analysis suggests that active management (prescribed fire and timber harvest) could enable the simultaneous movement toward the goals of developing complex forest structure and reducing high-severity fire, while also limiting watershed disturbance and providing a regular timber harvest.
