What I'm saying is, these problems of boggy pasture need looking at and analysing in the round rather than simply saying 'here's some wet ground, what animals would suit it best?'. It's a fair bet that the original makers of the meadow would have put some system in place to keep the ground reasonably dry, particularly in summer. Even the ground in purpose-made water meadows can harden and dry in summer. There are usually ditch systems round them which control the water table to manage otherwise boggy ground. They get abandoned and silt up then the field floods regularly. People think 'Oh, they're water meadows, that's why the field's permanently wet'. Not necessarily so.
