Field Trip - Indiana Dunes National Lakeshore - 12 of 12
By Paul Katula, Dateline: GARY, Ind. (May 27, 2006)


Succession is defined as the process by which a group of plants and animals in a particular space is gradually replaced over time by other, sometimes very different, natural communities. And when harsh wind and possibly storms wipe out any plant life that has established itself in an area, succession goes back to Square One. This desolate strip, usually on the side of a valley carved out by those same violent winds, is called a blowout. A few cottonwoods have already arrived. Just give this plot of land a few thousand years!
