The local council might be your saviour, then. It is likely that they will be equipped to spray bracken with Asulox, the only really effective bracken control. There is a temporary permission to use Asulox until, I think, the end of October, after which it will become banned again. However if their nature reserve is full of bracken it will come back to your strip of land by rhizome spread.
However, bracken is also susceptible to being physically bashed into submission, though that takes a little longer.
