Foes of Arnor

[Meneldil]

Previously, I posted this on another message board, but got no real response, and I'm hoping I may get some answers and good discussion here.

`And yet less thanks have we than you. Travellers scowl at us, and countrymen give us scornful names. "Strider" I am to one fat man who lives within a day's march of foes that would freeze his heart or lay his little town in ruin, if he were not guarded ceaselessly. Yet we would not have it otherwise. If simple folk are free from care and fear, simple they will be, and we must be secret to keep them so. That has been the task of my kindred, while the years have lengthened and the grass has grown.

What are these foes? Are they the barrow wights, and if so how do the Dúnedain stop them? The most feasible explanation I can come up with is trolls but I'm not too sure about that.
