okay i thought i'd try to give some info on low level mats in Tryker..i only harvest choice mats though and since i got the prospect choice only skill almost as fast as i could i dont know so much about basic/fine
For <q50 all you need is just around Fair Haven, around the stables and in the closest woods you can prospect for ambers(all around), nodes(left part of woods looking from stables), resin(midle part of woods), wood(can't quite remember where right now) a bit further in, close to the little pond, you can find seeds and resin.
Standing at the stables and looking right there is a pillar not far away, around that one you can find fibre, shells and bark.
The best place for harvesting up to q50 i think though is southeast of Fairhaven, you go past the south entrance and swim across the water to a small hill. To the left of this hill there is cloppers and some other mobs but they wont come up on the hill. Anyway, on top of the hill there is lots of different mats, it's kind of hard to explain exactly where since they are so close together but go there and have a look, atleast i did most of my harvesting there up to q50
When you need materials over quality 50 i'd suggest Winds of Muse, you can find up to q100 there and mostly there are not many aggros close to the main harvesting spots (if you want some better mats, like bigshells and yana node there will be a bit of a hazzle though) the safest places i've found for harvesting there is in the northern parts close to the Kami teleport (north-northwest) there is also a village a bit to the east with a hawker that might be nice, saving you some dappers for tickets back and forth
Close to that Kami teleport (+-100m or so) you can find resin, seeds, ambers, node, wood, fibre and a bit closer to the village you can find oil and some other stuff. Also just north of the lake there are similar spots with fibre, node resin, bark and more.
There are also lots of excellent spots around winds of muse but find these yourself since they are not available all the time anyway, a tip for shells though is to check around the lake, i've found all sorts of ex. shells there (except for bigshells grrr).
