Résumé : | During the last 150 years black woodpeckers are recolonizing some parts of Europe which were heavily deforested by man over centuries and then partly afforested mainly using non native conifer species in regions of temperate broadleaved forests. At the same time remaining forests were managed with higher rotation ages and reached as well as the growing afforestations much larger trees sizes und stocks as before. Because of their large sized cavities black woodpeckers are of conservation concern. In managed forests they are key species for some other large bird species, which use their cavities for nesting and roosting. Because the recolonization and populations growth of black woodpecker in these landscape is often coinciding with conifer afforestations the question arises, if conifer introduction in regions of broadleaved forests especially improves the habitat for this species or not. According to this question I analyzed data from large-scale inventories on woodpeckers and their habitats in conifer poor and conifer rich landscapes that would be naturally covered by broadleaved forests. The conifer poor National Park Poloniny in the Eastern Carpathians of Slovakia sustained a black woodpecker population with a more than double so high abundance as the conifer rich Nature Park Solling in northwestern Germany. Further the Solling was subdivided in two large strata, one dominated by broadleaved trees and the other heavily by conifers, what makes no difference for black woodpeckers from the point of view of their abundance in these strata as well as from their localization in broadleaved or conifer stands during the inventory. According to this, conifers and the related growing supply of ants of the genus Camponotus and Formica seem not to improve the habitat of black woodpeckers more than broadleaved trees. The habitat choice of black woodpeckers seems to be more generalistic and their feeding more variable as is often mentioned in elder literature. The much higher abundances of black woodpeckers in the Eastern Carpathians may be caused by the high supply of old, decaying and dead trees in these forests. High rotation ages and increasing supply of these trees are better opportunities to preserve and improve black woodpecker populations in regions of broadleaved forests than to introduce or continue with management of non native conifer species.
