When engine quit; I switched from empty tank to rear tank which was half full and it did not restart.  I was over some wetlands and I made a landing there. There was no damage to the plane or anything else.  I inadvertently allowed my Class 3 physical to expire and I am renewing it.
DHC2 pilot experiences engine failure at 2;000 FT when the tank suppling the engine is used up. After switching to the rear tank which is half full the engine does not restart and an engine out landing in wetlands ensues without damage.
