Ranger / Horizon walker skills

[JuliusCromwell]

Putting together a Horizon walker that Starts out as a warden Ranger.

I know I get a survival bonus via my Terrain and then another against fav enemies native to that terrain if you have Dominance in said terrain

Do they overlap or stack?

[Belafon]

They stack.

The bonuses from Terrain Dominance work like the ranger’s Favored Enemy bonuses.

As untyped bonuses, the survival bonus from Favored Terrain and the survival bonus vs. Favored Enemy do stack.
