Megjegyzések:Past and present pressures on forest resources have led to a drastic decrease in the surfacearea of unmanaged forests in Europe. Changes in forest structure, composition, and dynamics inevitablylead to changes in the biodiversity of forest-dwelling species. The possible biodiversity gains and losses due toforest management (i.e., anthropogenic pressures related to direct forest resource use), however, have neverbeen assessed at a pan-European scale. We used meta-analysis to review 49 published papers containing 120individual comparisons of species richness between unmanaged and managed forests throughout Europe. Weexplored the response of different taxonomic groups and the variability of their response with respect to timesince abandonment and intensity of forest management. Species richness was slightly higher in unmanagedthan in managed forests. Species dependent on forest cover continuity, deadwood, and large trees (bryophytes,lichens, fungi, saproxylic beetles) and carabids were negatively affected by forest management. In contrast,vascular plant species were favored. The response for birds was heterogeneous and probably depended moreon factors such as landscape patterns. The global difference in species richness between unmanaged andmanaged forests increased with time since abandonment and indicated a gradual recovery of biodiversity.Clearcut forests in which the composition of tree species changed had the strongest effect on species richness,but the effects of different types of management on taxa could not be assessed in a robust way becauseof low numbers of replications in the management-intensity classes. Our results show that some taxa aremore affected by forestry than others, but there is a need for research into poorly studied species groups inEurope and in particular locations. Our meta-analysis supports the need for a coordinated European researchnetwork to study and monitor the biodiversity of different taxa in managed and unmanaged forests.

Cím:National Responsibilities in European Species Conservation: a Methodological Review / Dirk S. Schmeller, Bernd Gruber, Eduardas Budrys, Erik Framsted, Szabolcs Lengyel, Klaus Henle
Dátum:2008
Megjegyzések:One particular challenge in reducing the loss of biodiversity by 2010, as agreed on at the Earth Summit in 2002, is to assign conservation tasks to geographic or administrative entities (e.g., countries or regions) on different geographical scales. To identify conservation tasks, it is imperative to determine the importance of a specific area for the global survival of a species. So far, these national or subnational responsibilities for the conservation of species have been included differently in methods prioritizing conservation. We reviewed how 12 European and 3 non-European methods determined national conservation responsibilities and evaluated the international importance of a biological population. Different countries used different methodologies, which made a direct comparison of assessments of national responsibilities among countries extremely difficult. Differences existed in the importance criteria used. Criteria included population decline, range reduction, rarity status, degree of isolation of a population, endemism, proportional distribution, and geographic location. To increase comparability, it is imperative to develop criteria for which data are generally available and to standardize the methodology among countries. A standardized method would allow conservation decisions to be based on the conservation status of a species and on the responsibility of a geographic or administrative entity for the survival of a species. We suggest that such a method should use a scalable index of proportional distribution, taxonomic status, and the distribution pattern of a taxon or species as key elements. Such a method would allow for the creation of hierarchical lists and would be highly relevant for parts of the world with multiple political jurisdictions or state unions and for nations with regional governmental structures. Conservation priorities could then be reasonably set by combining national responsibility assessments with the international conservation status of a species.
