Agreed on the cariad ysbryd ability. That should probably work with pretty slight modification. Maybe just drop the "linking" bit. Do you agree? Good memory, by the way.
Yes, we don't need the linking bit, and we might as well simplify the text a bit. I fancy changing the name as well.
How's this:
Ecosense (Su): A warden beast is mystically tied into the ecosystem of its territory (an area up to 10 miles across). The warden beast instantly senses when major changes affect the living creatures of its territory, such as the territory's plants or animals being killed or injured, a flooding river, or a large group of creatures entering its land.
Any effect that opposes divination spells, such as the nondetection spell, will also oppose a warden beast's ecosense. Ecosense can penetrate barriers, but 1 foot of stone, 1 inch of common metal, a thin sheet of lead, or 3 feet of wood or dirt blocks it.
