A few Ideas...
Black locust is great, don't inhale the dust from it though, clots your 
blood.  O sage orange and oak are also rot resistant.  There are references 
on wood characteristics out there so you can check for locally available 
stuff.  As for treated lumber, if you can find it WO arsenic you should be 
OK.  Plastic is Ok with me, help pump up the recycling market.  You might 
also consider used concrete, plenty available in more less stack able 
slabs.  You might even get paid to haul it away.  You could chink it 
together with soil and plant herbs, violets, strawberries etc in the cracks 
to keep it looking good.
