Elm Bough

Elm boughs can double as Branches in crafting; though they aren't usable as fuel.

Elm boughs may be used in any construction or recipe that lists "Any Bough" as an ingredient. Some items that specifically list Fir Bough will not accept Elm Boughs.

"Elm boughs are now usable as fodder for animals." quote from jorb. source: http://www.havenandhearth.com/forum/viewtopic.php?f=6&t=5921
