This page isn't as much a guide as it is a map for all the different Ancient Wood nodes I have found in the game. There will always be nodes not listed here since they are always changing but consider this a constant source of new information for when I find a node that isn't on this page. And a source of information of known locations or areas you could hunt to find Ancient Wood Spawn Locations. I will update it as much as possible but for now, here you go!
Important: It is extremely important to remember that a lot of spawn locations for nodes such as Orichalcum Ore, Ancient Wood, Omnomberry and other popular farming materials are constantly changing. While my map might say there are X amount of an item somewhere this may not be the case this week.
If you follow the links below you'll find all of the Orichalcum Spawn Locations as well as Ancient Wood Spawn locations listed on big map pictures instead of broken down into their own individual pictures. It may be easier to understand for some people.
Cursed Shore - Orichalcum & Ancient Wood Hotspot Desmina's Hallow
This location deserves to be completely singled out because at almost all times there is an orichalcum node and Ancient Wood here. I have found that no matter how many times the nodes change Desmina's Hallows always has at least one but typically two active Orichalcum and Ancient Wood nodes present. If you want to find some easy Orichalcum or Ancient wood without too much running around aimlessly, come here!
Central Frostgorge Ancient Wood Spawn Location
This is in central Frostgorge Sound, take the Slough of Despond Waypoint and swim across the short little ocean area to reach the Orrian Sapling nodes.
Eastern Malchor's Leap Ancient Wood Spawn Location
North of Pagga's Waypoint. This is one of the easiest Ancient Wood nodes to get.

This spawn point is in the center of Desmina's Hallows and has almost no mobs around it. Unless of course there is an event going on in the area.

Very easy Orrian Sapling to get to, just run north of Wren and it's right out in the open.

This spawn point is pretty easy to get too. A lot of mobs are surrounding it though so be careful.

It's quite common for Ancient Wood to spawn in the area north of Arah/South of Jofast's Camp.
