Shia LaBeouf -- Log Jammin' ... Takes a Huge Load (PHOTO)

Shia LaBeouf's got wood ... LOTS of it -- after hauling off huge loads of logs in L.A. 

Looking like a hybrid of a hipster lumberjack and a smooth jazz DJ -- ponytailed Shia was doing some major wood work Monday ... hauling logs with TreePeople, an LA based non-profit environmental organization.

Hard to tell what Shia's up to now -- bizarre art installation, DIY home improvement project, or just charity ... honestly, we're stumped. 

At least we're one step closer to knowing how much wood a LaBeouf would chuck if a LaBeouf could chuck wood.
