Meadows like that are mostly the result of cutting for hay or grazing at certain times of year, it might look kind of disastrous to go in and cut it all down but not regularly removing nutrients encourages coarse grasses and other weedy stuff like docks, nettles, cow parsley
There are a few places with naturally very poor soil will produce suitable conditions, you sometimes see it in the most unlikely locations such as steep motorway verges.
(fairly) locally at Redcar the old steelworks used to tip slag and other waste out over sand dunes until the 1960s, that area is now a remarkable reserve with orchids and many other plants not found anywhere else along the coast.
