PNW moss for soil?

My friend is in WA right now and he says his forest is full of all this green moss, we're wondering if it can be harvested and composted or used as peat moss? Any tips?

Moss kinda seems like the rapid response team for covering over any bare on the mostly clay soils around here I leave mine in place to keep the sun and beating rain off and mulch and plant over it.

I'm sure that the soil below the moss is already made of composted moss - why not harvest some of that and let the moss keep making more?

Yeah, I mean I don't know the exact situation, but moss does protect the soil from the sun and rain and spring can bring both in various fluctuating degrees of extreme. If its under a full canopy there probably isn't a reason not to steal some, but the hazards of bare dirt must be stressed.
