Résumé :

[The following tentative conclusions have been drawn from a reconnaissance study of the ecology of hedges in the British Isles during 1961-66. Hedgerows, which have been an important feature of the landscape for at least 700 years, are being steadily destroyed throughout the British Isles. The rate of destruction varies between regions. In one district 71% of the total original length of hedges has been destroyed during the last 20 years. Away from roads very few new hedges are being planted. Hedges can be classified by the predominance of shrub species. The different species types vary between regions. Hawthorn hedges, and mixed hedges containing more than three shrub species, are the commonest types. A survey in the Purbeck region of Dorset suggested that geological formation and hedge type are associated. The relative abundance of hedges of different management types varies from region to region. Many bird species of farmland depend on hedges. Species and numbers depend both on the shrub species and on the type of hedge management. The abundance of different hedgerow trees varies between regions. The proportion of saplings to mature trees is less now than it was in 1951.]
