Here's an interesting note...
Only hitting about half or less of the resource squares along the way, walking from my house at the Yew Crossroads (the one between the liches and the Cemetary), in Trammel, with a Human lumberjack, in a dogleg trip (straight, other than detouring around the cemetary to keep the packies from chasing skeletons)
...I was able to fill up 2 packies and half of a third with boards (not logs) of various types (the other half of the 3rd packy was boards brought from home), plus my own pack (approximate 300 boards plus tools, could have gone closer to 450 if one was able to enter Heartwood while overweight - in fact, I had to leave some outside, and came back for it after dowing 2 bow quests).
Had it been serious logging, could have filled 5 empty packies in the trip, even with a human in Trammel.
granted, the only high-end wood I hit was heartwood (ironically AT the LJ-capable tree next to the Heartwood emissary & entrance).
