Frank,
The pros of straw:
Helps erosion,Doesn't blow around,allows seedlings to push upwards more easily due to it's texture, conserves moisture for those seed that didn't make it under soil so they don't dry out
The cons:
It sticks out like a sore you know what and says \"Woo Hooo, over here! I've got something really fishy going on in these woods!\"
There really is no greater benefit other than it doesn't mat down like some larger leaves can do which will sometimes not allow seedlings to emerge but, it is a benefit. I myself, use it. After completely clearing an area of leaves and putting them out of the way, it seems easier to use the straw. It's faster than raking them back on a tarp and pulling them up a hill. It takes about 40-50 to do a half acre. If a person were doing beds here or there then I would just use the leaves I think but with a large area I usually wind up with a piles of leaves filled with rock,branches and dirt. We get some strong winds in Winter which blows the leaves all over, you can put an excessive amount to make sure you have coverage but then you risk them matting.
