Best Spots For Birch & Barley?

I looked all over the map and you get some barley and birch scattered around, but I was wondering if there was an all birch forest and barley farm, or something close to that, thanks.

 

There isn't much for Birch (though it's not really a big deal since it's low-level), but there's about 12 nodes of Barley on one of the Durum Isles.

 

Here's a really useful guide, so you will always know where you should gather materials:
