I'd put weather prediction, terrain lore, wayfinding, finding water, identifying edible/medicinal/poisonous plants and knowing cycles under Survival - If I'm in the wilderness hunting then I need to know where its safe to go, what the weather is doing, what plants I can eat and what to avoid, where the animals are going to be, etc etc all so I dont die.
Maybe I dont know that the Sekwaka Tree thrives in limey soils and tend to grow in clusters of 7 to 15 plants, but survival lets me know if I can eat its fruit when theyre yellow but not when they develop purple spots
