Does a Horizon Walker's DR / adamantine stack?

[Gluttony]

Simple one:

Does a Horizon Walker's DR 1/adamantine from Terrain Mastery of the Plane of Earth stack with his DR 2/adamantine from Terrain Dominance of Mountains, becoming DR 3/adamantine? Or would the DR 2/adamantine simple take precedence over the lower DR?

[Cao Phen]

No. Unless stated otherwise, Damage Reduction does not stack.

I believe the higher DR takes precendence over the lower.

As thaX said, the higher DR takes precedence. You can have multiple types of DR, though. DR 5/- and DR 10/magic will give you 10 points of DR unless it penetrates magic, in which case it will give you 5 points of DR.
