47) In particular, the intentional introduction of a revived species into a biotic community
of which it was never a constituent might be regarded as necessarily a degradation of native biotic communities and natural ecosystems, akin to an invasive species that makes the existing community ostensibly less authentic.
Nonetheless, the species is absent from most of Arizona's desert grassland, which is a semidesert grassland biotic community
within a temperate climate (Brown, 1994a; McClaran and Van Devender, 1995).
One of Leopold's most endearing ideas came from this book, that of the "land ethic," the moral imperative that "a thing is right when it tends to preserve the integrity, stability, and beauty of the biotic community
He proposed a dramatic change in how we view and relate to the natural world, advocating a "land ethic" based on preserving the integrity, stability and beauty of the biotic community
His 1925 American Forests' magazine article, "The Last Stand of the Wilderness," became the basis for American Forests' national campaign for wilderness preservation.
That's counterproductive if our long-term goal is to expand justice, which requires that our species become a "plain member and citizen of the biotic community
," as Aldo Leopold counseled.
The move from the human community to a biotic community
, then, requires that we recognize a complex system of mutually interdependent parts that includes "soils, water, plants, and animals," and that we be able to give an account of how we can frame generally reliable, albeit fallible and corrigible, judgments about the needs and interests of the non-human parts of such a system.
change can follow different pathways depending on physicochemical conditions and the susceptibility of the waterbody to nutrient enrichment (Figure 4).
We used to strive to interweave architecture with the human and biotic community
, but that presupposes a separation between the three, requiring a joining together.
