An '''ecoregion''' is defined as being a cartographical delineation of distinct [[ecology|ecological]] areas, land or water, identified by its [[geology]], [[topography]], [[soil]]s, [[vegetation]], [[climate]] conditions, a distinct assemblage of natural communities and [[species]], [[water]] resources, as well as anthropic factors. | An '''ecoregion''' is defined as being a cartographical delineation of distinct [[w:ecology|ecological]] areas, land or water, identified by its [[w:geology]], [[w:topography]], [[w:soil]]s, [[w:vegetation]], [[w:climate]] conditions, a distinct assemblage of natural communities and [[w:species]], [[w:water]] resources, as well as anthropic factors. | ||
//''I have a problem with the definition given by WWF, as it add to this one "with boundaries that approximate the original extent of natural communities prior to major land-use change". I think this approach tends to consider that these areas were static (which is only true on a very small time scale) and the preanthropic areas were the "right" ones (when thinking in terms of biodiversity conservation). Besides, on some continents, it is likely major land-use change occured quite a long time ago. I think they focuse too much on what would have been expected to be found given local conditions, "if" human had had no impact whatsoever.<br>'' | //''I have a problem with the definition given by WWF, as it add to this one "with boundaries that approximate the original extent of natural communities prior to major land-use change".
