Yes / In recent years there has been concern about the decrease in the quality and quantity of
Britain's heaths and moorlands. This concern has prompted attempts to monitor change in
moorland vegetation, and programmes of action designed to halt the decline, both
nationally and locally (Bunce, 1989; Hudson & Newborn, 1989a).
In northern England the decline has been brought about partly by a reduction in the areal
extent of the moors but mainly by changes in their species composition, with Calluna
vulgaris (L.) Hull (heather) declining and grasses, Empetrum nigrum L. (crowberry) and
other species increasing. These changes have been attributed to changed management
practices, such as less effective burning regimes and increased sheep grazing (Bunce,
1989). However, there are few detailed quantitative studies of long-term vegetation change.
This paper draws upon historical records to determine the nature and extent of change in
the vegetation of Ilkley Moor over a twenty-year interval.
