Good response, Wayne. Yes, we do need to question assumptions, and also terminology including the use of currently in vogue terms such as "ecosystem" "sustainable" "green" "ecology" etc.
If we define ecosystem as the community of living organisms plus the non-living environment, then everything from the crack in the sidewalk to a lawn to a rice field to a landfill to a tree farm to a wilderness to an ocean to the planet earth can be defined as an ecosystem -- some certainly more natural than others, and some certainly very pauperate of a variety and wealth of living organisms. So I think your use of the term needs to at least be qualified, e.g., "natural ecosystems" (I prefer the more general term "natural systems" because of the tawdry overuse and devaluation of the word "ecosystem"). The word "sustainable" has suffered from the same overuse and devaluation. Too many accept the "cheapest" definition (meeting the needs of the present without compromising the ability of future generations to meet their own needs). This can imply some sort of faith in technology that will benefit future generations, so we can use up nonrenewable resources or we can degrade renewable resource systems because technology can find something to take their place. E.g., topsoil erosion is sustainable because future generations can replace the lost soil horizon with mulch and fertilizer. Overallocation of ground water is sustainable because future generations can recharge the aquifers. Urbanization of productive farmland is sustainable because future generations can ship food in from further away. I prefer a stricter, more costly definition of sustainable: "To maintain forever the current productivity of renewable resource systems including soils, waters, forests, wildlands and the atmosphere, and to deplete nonrenewable resources only at the rate that cost-relative substitutes can be developed, with costs measured on economic, social and ecological scales." And I don't need to pontificate to ecologists on how the term "ecology" has been degraded, e.g., "we have to take care of the ecology" and "the threat of eco-terrorists." Warren W.

Aney; [email protected] Subject: Ecosystem Definition as Sustainable Re: SUSTAINABLE SITES INITIATIVE - we need your feedback. Dear Warren and Forum: I was trying to come up with different ideas, not criticize theirs. I wish them well, and hope that they will vigorously refute any or all of my responses to their request. It is not my intention to manipulate, but to stimulate. Either the points I have made are true or not true, more true than untrue, or more untrue than true. All may judge them, and, I hope, refute or validate them with intellectual and scientific--CRITICAL vigor. I do see that they are trying, and a laud their efforts and willingness to ask ecologists for "input" (if not invite them to join them). I hope others on this list will make suggestions that are more potent than mine. Intellectual progress, however, comes from questioning assumptions (especially one's own), not manipulating others or being manipulated by them. It is a NEUTRAL process, neither positive nor negative--merely inquisitive. I guess my definition of ecosystem is defecktive. I consider landscaping that is dependent upon intervention for its persistence to be a cultural artifact, not an ecosystem. A crack in the sidewalk, while not intentionally maintained, is at least indirectly a result of a cultural influences, but more subject to ecosystem processes (colonization and selection of ecotypes if not genotypes), so I'll give you that much. I'll even extend that to "old fields" covered with alien plants--a point I was not so willing to concede fully until Ma Nature gave me a good slap back in '80. In landscaping and gardening, one is altering the environment that has produced a biological complex (ecosystem) congruent with that environment and its fluctuations. Landscaping and gardening act against, not in concert, with that congruity. When the external (cultural) influences are withdrawn, a process of readjustment begins, in accordance with the altered environment, and the biological complex changes to one independent of those influences. The complex of organisms that ultimately develop must do so in accordance with interacting with each other and the environment altered by cultural influences, and often come to at least resemble those which originally occupied the site, but at least more so than not. The exception to this is when the cultural alterations (e.g. alien species introductions) continue to reproduce more than the recolonizing species which once occupied the site. Much of the Hawaiian Islands could serve as an example of this latter phenomenon. The list of species lost because of alien introductions and the "alteration" of the ecosystem is staggering, however true it might be that the present simplified biological complex must be called and ecosystem. Even farming, with its wholesale destruction of ecosystems, may not be as destructive as ornamental horticulture, in terms of permanent effects. Therefore landscaping that is NOT dependent upon intervention for its persistence is a culturally-induced biological invasion. To me, ecosystems in the plural are cultural (ecology) categories of convenience (therefore valid within that box or those boxes) but the "real" ecosystem is the earth on its own (though that might not always be strictly the case if, say, it turns out that all life here hitch-hiked here courtesy one or more comets, in which case we may have to consider the Universe to be an ecosystem). The crucial distinction to me is the self-sufficiency and adaptation of organisms according to the realities of the habitat. When the definition of "ecosystem" goes beyond that, then any smidgen of life, however transitory or dependent upon inputs external to the natural habitat "qualifies," and thus anything goes--and the term loses its meaning. As does "sustainable." WT At 10:09 PM 12/14/2007, Warren W. Aney wrote: >Aw, c'mon Wayne. Can't you see that they're trying.
