Project description
Retention forestry and large mammals in European forests
Retention forestry aims to reduce the negative effect of forest transformation and homogenisation on biodiversity. It is a promising tool to meet sustainability goals like those set forth in the EU Forest and Biodiversity strategies, and the practice has been adopted in some forests in Central Europe. The planning of efficient retention strategies depends on ecological knowledge, but it is unknown how large terrestrial mammals respond to variable retention harvesting in temperate forests. The EU-funded ConFoBiNM project will investigate how the large mammal community changes in response to varying levels of retention forestry. It will use the Black Forest in Germany as a model system for multiple-use continuous-cover forest landscape in Central Europe, and will apply a combination of advanced survey techniques (camera trapping) and Bayesian statistical methods.
Objective
The integration of conservation into production forest management is crucial to achieve desired biodiversity goals at the EU level. Retention forestry, which was introduced as a tool to mitigate the negative impact of transformation and homogenization of forests, is now common practice in Central European forests. The design of efficient retention strategies hinges on ecological knowledge, yet research-based evidence for its effectiveness is lacking. In particular, responses of large terrestrial mammals to variable retention harvesting are unknown. I will address this knowledge gap by using a combination of advanced techniques and statistical methods to investigate how the large mammal community changes in response to varying levels of retention forestry in multiple-use forests, and assess the interplay between retention forestry and the surrounding landscape. I will (a) quantify mammal species richness, species-specific abundance and β-diversity across a gradient of retention forestry and landscape forest cover, and (b) determine a threshold of retention at which significant responses occur. I expect that retention will enhance mammal diversity, but not below a certain threshold or below a certain amount of forest cover. I will use the Black Forest in Southwestern Germany as a model system for multiple-use forests in Central Europe, and conduct camera-trapping in 135 plots embedded in patches of mixed-montane forests which differ along 2 gradients of retention and landscape fragmentation. I will use multispecies hierarchical modeling in a Bayesian framework to quantify the effects of retention forestry on mammal species at different spatial grains. This multidisciplinary research combines spatial ecology, with landscape and forest ecology and will integrate for the first time ecological study of large mammals and retention forestry in Central European landscapes.
