I've foraged many hundreds of these in every foragable zone, and by far the two best places are the cities of Thurgadin and Kael Drakkel. These two cities have nearly identical forage tables, and both provide Tufts of Dire Wolf Fur at exactly the same rate. Here is what you can get from most common to least:
Glob of Slush Water (very common)
Acrtic Mussels (common)
Arctic Scallops (common)
Tuft of Dire Wolf Fur (less common)
Chunk of Velium (Thurgadin) and Arctic King Crab (Kael) (rarer)
Roots (quite rare)
Pod of Water (very rare)
7 foragable items. Every other zone has at least 9. Plus, 2 of them are very rare, and hardly ever come up. So it's almost as if there are only 5 foragable items, which means Tuft's come up quite often.
If you are not KoS in Kael, or can Hide, then I recommend foraging there. The Arctic King Crab is stackable. The Chunk of Velium which come from Thurgadin are not. You can quickly fill up your available inventory slots in Thurgadin for those of you which AFK forage (shame on you! :-). Of course, if you are not AFK can destroying the velium anyway, the two zones are identical from the perspective of foraging for Tufts.
I don't have a firm statistical analysis, but basically roots are about twice as common as pods of water, but still both quite rare (2% to 4% or so). Globs of Slush Water are by far most common, perhaps 30%. Then Mussels and Scallops are both about 20%, and Tufts around 16%, and Chunk of Velium (Thurgadin) or Arctic King Crab (Kael) around 10% or so. The water is worthless (other than for a drink), but the mussels, scallops, and crab can all be sold at vendor.
