dc.description.abstractThe delta of the Colorado River, praised for its wealth of wildlife, has <br /><br />been dramatically altered by agriculture. In this article we provide a basic over- <br /><br />view of the status of the aquatic wildlife of this area. Overall there is a great lack <br /><br />of knowledge on the status of the different aquatic species in the area, but negative <br /><br />impacts include the disappearance of the massive riparian forests, a reduction in <br /><br />the populations of native fish (very severe), a number of birds, two mammals, <br /><br />and possibly one amphibian and two reptiles. Conversely, habitat transformation <br /><br />might have benefited some amphibians, some birds, and one mammal. Alien <br /><br />aquatic taxa that have been introduced to the area or have colonized it include <br /><br />some plants, 4 invertebrates, more than 20 fish species, 3 amphibians, 3 reptiles, <br /><br />and 1 bird. We conclude that the area is far from being biologically intact, and <br /><br />that it does not meet the legal criteria for being a Biosphere Reserve, as it has <br /><br />been declared. Listing of some of the species as at risk is unsupported. Although <br /><br />the area is biologically very modified, it can provide important opportunities for <br /><br />the conservation of wetland taxa.
