Opis predavanja (Abstract)

Veteran trees, i.e. trees bearing deadwood and its microhabitats, such as hollows, bare wood or fruiting bodies of fungi, host rich communities of associated biota with many specialists and endangered species. However, these trees have become rare and scattered, and their ongoing decline represents an actual threat for biodiversity of temperate woodlands. This is in a contrast with the fact that in last 200 years, cover of woodlands has considerably increased in most of Europe. The reason behind the loss of veteran trees is the intensification of forestry management together with abandonment of traditional silvicultural practices that has lead to a substantial increase in canopy closure and to a transition from former open woodlands to closed-canopy mesic forests. Interestingly, the veteran trees are not safe even in protected areas where minimal intervention regime often leads to homogenization of woodland habitats in a similar way as in productive landscape. In order to mitigate further loss of biodiversity, modern conservation needs, first, to gather data on habitat requirements of veteran trees and their associated biota, and second, to apply suitable, often active management practices.
