Vegetation Changes on Ilkley Moor 1964-1984Cotton, David E., Hale, William H.G. January 1989 (has links)
In 1970 a set of maps was published which summarized the results of an extensive survey of
the vegetation of Ilkley Moor. This paper presents new maps showing the distribution of
selected vegetation communities based on a detailed survey undertaken in 1983-84, and
examines the changes which have occurred in the period 1964--1984.
Comparison of the maps reveals that Calluna vulgaris and Pteridium aquilinum have
increased their occupancy of the moor, whilst there has been a marked reduction in the
abundance of Empetrum nigrum and Eriophorum spp. These changes indicate that the
degradation of the moor which was recorded during the 1960s was reversed, at least
partially, between 1964 and 1984.

Vegetation Changes on Ilkley Moor between 1964 and 1984, and Possible Environmental CausesHale, William H.G., Cotton, David E. January 1993 (has links)
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.
