I was wondering this also. I was looking for logging points in Fort Karugo-Narugo for 3 days to get Nopales for WotG mission (red textile dye). No one was in the zone logging during the time I spent there (hours!!) I read this from wiki "Logging points":
Logging Points will disappear if they have been emptied of all contents or have not been touched for a period of time.
The only place I found any logging points was in the area heading to Meriphataud Mountains area...which is swarming with yagudos. Died once (lol) but got 1 nopalas -- which synths 12 red textile dyes. More than enough for my static WotG group

But the area does need some attention to the logging points.
