‘Life can only be understood backwards but it must be lived forwards’.Thirty years of professional but spasmodic interest in the problem of bracken on the Scottish hills brings home the aptness of Kierkegaard's aphorism. Despite rapid technological change —from a man with a scythe to the pilot with a helicopter—the fact remains that control of this serious weed problem is currently running at only a fraction of the rate in the early fifties. Clearly, financial factors have played a major part in this situation but it is facile to lay the blame wholly at the door of economics. The objective of the paper is to summarise the dominant technical and economic aspects which have impinged upon the problem over three decades and to attempt to draw broad conclusions as to why we are in this situation and to outline more fruitful possibilities for the future.
