Domain‐specific neural networks improve automated bird sound recognition already with small amount of local data
1. An automatic bird sound recognition system is a useful tool for collecting data of different bird species for ecological analysis. Together with autonomous recording units (ARUs), such a system provides a possibility to collect bird observations on a scale that no human observer could ever match. During the last decades, progress has been made in the field of automatic bird sound recognition, but recognizing bird species from untargeted soundscape recordings remains a challenge. 2. In this article, we demonstrate the workflow for building a global identification model and adjusting it to perform well on the data of autonomous recorders from a specific region. We show how data augmentatio…
A synthesis of multi-taxa management experiments to guide forest biodiversity conservation in Europe
Most European forests are used for timber production. Given the limited extent of unmanaged (and especially primary) forests, it is essential to include commercial forests in the conservation of forest biodiversity. In order to develop ecologically sustainable forest management practices, it is important to understand the management impacts on forest-dwelling organisms. Experiments allow testing the effects of alternative management strategies, and monitoring of multiple taxa informs us on the response range across forest-dwelling organisms. To provide a representative picture of the currently available information, metadata on 28 multi-taxa forest management experiments were collected from…
Biodiversity and ecosystem services in forest - the ‘BioHolz’ project
Whenever a tree dies, it makes room for millions of organisms contributing to the crucial ecosystem process of decomposition. The diversity of saproxylic organisms, which are depending in at least some stage of their life on decaying wood, comprises about one third of all forest species. Forest management in Europe of the last centuries changed forest structures and in particular reduced the amount of available dead wood, which is mirrored by the current extinction risk of saproxylic species1. However, society expects a forest to be a multi-functional ecosystem, which provides, among others, timber, recreation and biodiversity conservation. In the trans-disciplinary project ‘BioHolz’, we tr…
Integrative forest management can promote biodiversity
Integrative conservation strategies that combine production of commodities and conservation, are considered as a valuable tool to promote biodiversity in unprotected areas. In forests, a considerable proportion of biodiversity is dependent on deadwood structures, and an enrichment of deadwood is often proposed as important integrative conservation measure. The Bavarian State Forestry in Germany has implemented an integrative nature conservation strategy where the key element is the enrichment of deadwood during harvests. Deadwood is accumulated by leaving large and small diameter wood usually sold as firewood (discolored stems, crowns) after harvest combined with a retention of naturally de…
