Spatial Partitioning Terrain and Stationary Objects
Imagine that I have a terrain and various stationary objects in my scene. A good example would be a field with trees, bushes, shrubs, etc. The Terrain will not change, however the trees and shrubs may sway in the wind. What would be the best way to partition this scenario?
Octree for Terrain and BVH for Objects?
The only problem I see with a Quad tree is that it may not be as effective in Frustum Culling when displaying a cliff or mountain (because the triangles are now going up the Y-axis.

You are right although on todays GPU's, a few triangles here and there won't be such a performance hit! If you want to optimize your terrain rendering then you might wanna use other efficient culling methods and LOD not just frustum culling.
