The positive side of big floods

13 January 2011

While big floods are devastating to man and property, they encompass all sorts of ecological benefits.  As with other natural disasters (disasters in human terms, long-term cyclical events in nature), massive floods bring about a “reset” in the status quo insofar as the dispersal of organisms are concerned.

Floods allow otherwise isolated aquatic fauna to be relocated to new habitat, in the processing not only “restocking” but also introducing new genetic material into stagnant gene pools.  There are, of course, some downsides, as the same applies to introduced species of fish and other fauna, which will now be even more widely distributed than they were before.
