What are POC arrows.What does POC stand for??

It's just a short way of saying Port Orford Cedar. POC is the wood that wood arrows are most commonly made of.

Port Orford Cedar shortened to POC.
Harvested at Port Orford, Oregeon.
That's my story and until I have more coffee, I'm sticking to it.

Port Orford Cedar is the name of the tree but it is not necessarily harvested in Port Orford, Oregon:  http://en.wikipedia.org/wiki/Chamaecyparis_lawsoniana  
Similarly, Sitka Spruce is the name of a tree but it is not necessarily harvested in Sitka, Alaska:

Port Orford cedar used to range up and down the s.w. part of Oregon and into n.w. California. There is less than 200 acres of marketable POC left on national forest lands in Oregon.

If I am not nistaken it also occurs in a limited area in Japan. There are a few other plant specie that are found in both locations. Our native cane, Arundaneria is very similar to a cane in Japan but I'm not sure which one.
