There is a certain like tree stump in vagulro that gives you a bit of sap and there is also a fuzzy, furry looking tree in the desert that you harvest for sap. Yes you can use the redwood tree taps but those take ages to start producing sap so this is a quick way to get some sap I don’t think this is on ark mobile though

You can craft a tree sap tap and attach it on the redwoods large tree...they will produce overtime up to 20 saps

How to get slotcap of sap real quick
1. Tame yourself a bronto
2. Go to any lunar cave and hit the yellow plants

A Theri leveled in delicate harvesting and melee can gather sap from the Joshua trees on scorched/extinction/rag about as efficiently as a chainsaw, and without expending any fuel.

Don't waste time with tree taps. Just go on valguero and farm redwood tree stumps, you can find them even on spawns

Gachas can "produce" these. I call those Gachas "Saps".

Not really a tip but how long does it take for sap to get collected
