Résumé :
|
A group of woodland species has been threatened by changes in land use: those that depend on old trees, and dead and dying wood. Having 'sorted out one end of the woodland cycle there was a need to raise the profile of species at the other end -fungi, lichens and saproxylic invertebrates. A symposium organised by the Parks Department of the Colporation of London on pollards, veteran trees and their management attracted over 200 people. To carry this enthusiasm forward we decided to organise this meeting, which concentrated just on the invertebrate perspective. The contributors were chosen to cover a wide range of aspects. The first two papers set the scene in terms of the historical origins of our saproxylic fauna and the significance of our sites and species in Europe as a whole. The third is a detailed study of species in one wood and illustrates how scanty is our knowledge of the ecology of even some common species. The fauna of parkland is probably better understood but further survey is still needed, and this and the management needs of such sites are considered in the fourth paper . Those concerned with conservation must however be aware of the conflicts that may (or may be perceived to) exist between looking after these special invertebrates and other uses of woodland or parks. The possible threats to commercial timber production and public safety questions are the subjects of the fifth and sixth papers. The final paper pulls together some of the practical ways in which conservation of deadwood invertebrates can be furthered, and we have supplemented this by two annexes on guidelines for surveys and the treatment of storm-damaged woods.
