Impact of Grazing and Nitrogen Deposition on the Condition of Racomitrium lanuginosum on the Carneddau Mountains
Results of work conducted on the moss heath habitat of the Carneddau massif to establish whether the overall condition of the dominant woolly fragile moss Racomitrium lanuginosum was associated with grazing pressure. The purpose of this data capture was to: - Determine whether the condition and growth of R. lanuginosum (on the basis of tissue chemistry, physiology, and growth rate) differs in areas of differing grazing intensity. - Investigate the recovery potential of R. lanuginosum under the current pollution climate if grazers were removed. - Find out whether membrane potassium leakage from R. lanuginosum shoots increases under increased levels of trampling damage and whether the depth of R. lanuginosum is affected by increased levels of trampling damage.

The location, altitude and aspect of 31 randomly distributed plots were recorded. Two sample points were set up at each plot. A composite sample of Racomitrium shoots was collected from each sample point for tissue chemistry analysis. The samples were used to analyse the nitrogen assimilation capacity of R. lanuginosum, compare shoot growth between different habitats and measure membrane potassium leakage. Simulated sheep trampling was undertaken to evaluate whether sheep trampling damages moss tissue causing membrane potassium ion leakage. This work follows on from a study the year before looking at the condition and conservation of montane heath and summit heath vegetation in Wales (CCW Science report 643).
