Creating a field of models...batching?

I'm looking to create a field of 200+ models each having about 50 vertices and I don't know how many faces cuz I don't have it in front of me. I'm low-balling this estimate which is 200x50 = 10000 verts. It could very easily be way more than that. I'm using Unity free version, and from what I've read I haven't come to any good conclusions on this. The field is part of the environment, so the player will be in the middle of it.

All the objects use one material, they just have tweaked meshes. So is it better to import the whole field as a single object, or import them in chunks or as individual objects and then do some kind of combine in Unity? Importing the whole field at once resulted in Unity automatically breaking the mesh into groups - that's how many verts I'm working with. If I mark the field as 'static' in the inspector that won't help will it? According to a Unity document page this uses a terrible amount of memory. I think what I need is occlusion culling, so that I can have the whole field there but any faces not within the cameras view are not drawn. I would consider something like billboarding too but I read that's only something I can do with the terrain.

If anyone can point me in the right direction I'd appreciate it. Otherwise I may have to resort to doing something entirely different. For what it's worth my target platform is pc.
