Where is there one?
New England and England have them, particularly the latter.
Just watch enough episodes of British shows like Robin Hood and you will
see a bracken meadow. There are also photos in some of the better books on
the ecology of New England and England.
Are they in competition with grass?
Not sure. They are almost grass-free. They are mostly limited to moist
openings in moist or wet forest (hence "meadow". I do not know why these
particular places are still fern dominated.
Are they like
most fern and need water to fertilize?
Yes, but, like most ferns, it takes very little. Just a few drops. The
gametophyte is quite small.
Why aren't there more of
Were they more dominant before grass?

I also seem to remember an in-place semi-arid florule from the Late
Cretaceous preserved by a volcanic event that was dominated by a mixture of
ferns and brambly bushes (similar to roses).
