Application of a grazing model to predict heather moorland utilization and implications for nature conservation

Article Abstract:

A grazing model was used to audit heather moorland use by sheep in the Northern Isles of Scotland. Variation in use patterns was noted using guideline maximum utilization limits while around 15% of Orkney's heather moorland and 47% for Shetland was found overgrazed, based on sample grazing units. Grazing utilization was found greater along moorland edges and lesser in areas where statutory conservation designation is practiced and on land owned by conservation charities. The audit results imply that conservation management be undertaken to maintain extant heather moorland.

Integration of sheep production and nature conservation: experimental management

Article Abstract:

An experiment was conducted to study the impacts on sheep production, the flora and invertebrates of sheep grazing a southern England neutral grassland which has been taken out of intensive use. The study aimed to identify regimes that promoted faunistic and floristic species-richness even as they supported average levels of sheep production. The results of the study, which dwelt on sward heights, soil seed banks and vegetation, can be used to effectively manage nature conservation.
