While I agree with everything you've stated, I must point out that the Chandeleur Islands were initially "devastated and dismembered", as was the entire eastern 2/3 of the Louisiana coastline by the U.S. Army Corps of Engineers beginning in the late 1920s/early 1930s when the Mississippi River locks and dams, plus levee system was constructed. Jindal is just the latest in a very long line of political incompetents whose passions seem to include destroying the La. coastline.

You're absolutely right, and thanks for emphasizing this sad saga. The Chandeleur Islands are but one (dramatic) example of the wholesale deterioration of the coast resulting from the shutoff of sediment supply by the massive engineering experiments carried out on the Mississippi and its delta. The historic sequence of images that I posted back in May (http://throughthesandglass.typepad.com/through_the_sandglass/2010/05/80-miles-of-sand-berms-experts-express-doubts.html)illustrate this - and why the islands were particularly vulnerable to Katrina. The USGS report, that I have referred to earlier, contains, in Chapter D, a fascinating (but depressing) documentation of changes since 1869 (http://pubs.usgs.gov/sir/2009/5252/downloads/Chapter-D/Chapter-D.pdf).
