Laid Low

The scarcity of frost and heavy rain has helped bracken to stay upright in its dead bronzed state into December. Only a week ago it was standing tall.



Today’s wet snow will make a difference; it’s usually been forced down before this. There are large areas of bracken on Blacka and generally people don’t like it, seeing it as something undesirable and alien intruding onto the land. It’s rarely asked why people dislike it and why it’s there. An obvious question is what should be there that the bracken displaces? Many people would probably have some picture in their heads of a mix of grass and heather of the sort that is portrayed as a kind of ‘typical’ heathland. But as heathland is artificial and only exists in certain circumstances, when many conditions have been contrived to come together there are problems. While some kinds of heathland may remain stable for many years with minimal management others succumb to a bracken invasion even when management is carried out giving rise to calls for harsh intervention such as spraying with herbicide, cutting with heavy machinery etc. This seems hard on bracken that is a wholly natural plant simply going about its business. And that very harsh intervention also serves to damage other aspects of the vegetation.



My ‘take’ on bracken is that here it is simply responding to man’s over-exploitation in the past. The artificial suppressing of tree cover over many years has created ideal conditions for bracken to colonise and the spread of the ferns is therefore understandable, part of the process by which nature reclaims the land. Managers wanting to know how to respond to this have the simplest of choices: either attack with every tool at the disposal of industrial agriculture; or allow, even encourage, nature’s own remedy by allowing the colonisation to run its course in the shape of natural succession.



Trees will spread onto these artificially open areas in time and that will reduce the vigour of the bracken growth and gradually limit its impact. To follow this strategy you need to boldly acknowledge a perspective of many years during which the more vigorous species struggle for supremacy before eventually achieving a balance. During this lengthy period some species will take over for a time and then subside. But wilder land will always bring its own pleasures for the observer. The idea that a landscape whether artificial or otherwise should remain fixed in time is anathema to the natural world. A major reason for this being the obvious strategy is that returning the bracken dominated parts of Blacka to grouse moor status would be incredibly demanding. There is so much of it and the collateral damage would be unthinkable and so expensive as to bring the whole conservation industry into ridicule. But then is not that where they are already? It looks as if there’s only one way forward for responsible managers and I accept that they are hard to find. Natural and more wooded must be the future.
